Part I

ITEM 1. BUSINESS.

General

TGC Industries, Inc. is a Texas corporation, and its wholly-owned subsidiary, Eagle Canada, Inc., a Delaware corporation (collectively “TGC” or the “Company”), are primarily engaged in the geophysical service business of conducting Three-D (“3-D”) surveys for clients in the oil and gas business.  TGC’s principal business office is located at 101 E. Park Blvd., Suite 955, Plano, Texas 75074 (Telephone: 972-881-1099).  TGC’s internet address is www.tgcseismic.com.  TGC makes available free of charge on its website its annual reports on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K as soon as reasonably practicable after filing or furnishing such information with the Securities and Exchange Commission.

History

In April of 1980, Supreme Industries, Inc. (“Supreme”), formerly ESI Industries, Inc., formed a wholly-owned subsidiary, Tidelands Geophysical Co., Inc. (“Tidelands”), that acquired certain equipment, instruments, and related supplies from a Houston-based corporation that was engaged in the business of conducting seismic, gravity, and magnetic surveys under contracts for oil and natural gas companies.  On June 30, 1986, the Boards of Directors of Supreme and Tidelands approved a spin-off of substantially all of the shares of Tidelands owned by Supreme which were distributed as a stock dividend to Supreme’s security holders.  In July of 1986, our name was changed from “Tidelands Geophysical Co., Inc.” to “TGC Industries, Inc.” (“TGC”).  On October 19, 2009, we disclosed our entry into an agreement regarding the acquisition of the stock of Eagle Canada, Inc. (“Eagle Canada”), a Delaware corporation.  Eagle Canada was a wholly-owned subsidiary of Eagle Geophysical, Inc. and Eagle Geophysical Onshore, Inc. (the “Debtors”) which were debtors in a Chapter 11 bankruptcy proceeding in Houston, Texas.  Eagle Canada is in the business of providing seismic data and surveying services to the Canadian energy industry and has its principal place of business located in Calgary, Alberta, Canada.  By Order dated October 14, 2009, the Bankruptcy Court approved the sale of the Eagle Canada stock by the Debtors to TGC and authorized the Debtors to enter into a stock purchase agreement with TGC.  In accordance with the terms of the stock purchase agreement, the sale transaction closed on October 16, 2009, with TGC acquiring the Eagle Canada stock for a total purchase price of approximately $10.3 million paid from existing cash.

We are a leading provider of seismic data acquisition services throughout the continental United States and Canada.  As of December 31, 2010, we operated eleven seismic crews, seven in the U.S. and four in Canada.  These seismic crews supply seismic data primarily to companies engaged in the exploration and development of oil and natural gas on land and in land-to-water transition areas.  Eagle Canada’s seismic acquisition services are also used by the potash mining industry in Canada, and Eagle Canada has particular expertise through its heliportable capabilities.  Our customers rely on seismic data to identify areas where subsurface conditions are favorable for the accumulation of existing hydrocarbons, to optimize the development and production of hydrocarbon reservoirs, to better delineate existing oil and natural gas fields, and to augment reservoir management techniques.

We acquire geophysical data using the latest in 3-D survey techniques. We introduce acoustic energy into the ground by using vibration equipment or dynamite detonation, depending on the surface terrain and subsurface requirements. The reflected energy, or echoes, is received through geophones, converted into a digital signal at a multi-channel recording unit, and then transmitted to a central recording vehicle. Subsurface requirements dictate the number of channels necessary to perform our services. With our state-of-the-art seismic equipment, including computer technology and multiple channels, we acquire, on a cost effective basis, immense volumes of seismic data that, when processed and interpreted, produce more precise images of the earth’s subsurface. Our customers then use our seismic data to generate 3-D geologic models that help reduce finding costs and improve recovery rates from existing wells.

The Industry

Technological advances in seismic equipment and computing allow the seismic industry to acquire and process, on a cost-effective basis, immense volumes of seismic data which produce precise images of the earth’s subsurface. The latest accepted method of seismic data acquisition, processing, and the subsequent interpretation of the processed data is the 3-D seismic method. Geophysicists use computer workstations to interpret 3-D data volumes, identify subsurface anomalies, and generate a geologic model of subsurface features.

2

3-D seismic data are used in the exploration and development of new reserves and enable oil and natural gas companies to better delineate existing fields and to augment their reservoir management techniques. Benefits of incorporating high resolution 3-D seismic surveys into exploration and development programs include reducing drilling risk, decreasing oil and natural gas finding costs, and increasing the efficiencies of reservoir location, delineation, and management. In order to meet the requirements necessary to fully realize the benefits of 3-D seismic data, there is an increasing demand for improved data quality with greater subsurface resolution.

Currently, the seismic data acquisition industry is made up of a number of companies divided into two groups. The first group is made up of four publicly-traded companies with long operating histories who field numerous crews and work in a number of different regions and terrain.  This group includes us, Dawson Geophysical Company, Geokinetics, Inc., and CGG-Veritas.  These companies field approximately 50% of the estimated 81 seismic crews currently operating in the continental U.S. and Canada.  The second group is made up of smaller companies which generally run one or two seismic crews and often specialize in specific regions or types of operations.

We provide our seismic data acquisition services primarily to onshore oil and natural gas exploration and development companies for use in the onshore drilling and production of oil and natural gas in the continental U.S. and Canada. The main factors influencing demand for seismic data acquisition services in our industry are the levels of drilling activity by oil and natural gas companies and the sizes of such companies’ exploration and development budgets, which, in turn, depend largely on current and anticipated future crude oil and natural gas prices and depletion rates.

Equipment and Crews

In January of 2008, the Company entered into an agreement with a bank to provide financing for the purchase of new vibration vehicles.  In February of 2008, the Company exercised its purchase option for seismic recording equipment it had been renting.  In March of 2008, the Company entered into a loan agreement with a commercial lender to provide financing for the purchase of this rented equipment and to replace an existing loan the Company had with the lender.  In July of 2008, the Company entered into a loan agreement with a bank to provide financing for the purchase of additional seismic recording equipment.  In August of 2008, the Company entered into a loan agreement with a bank to provide financing for the purchase of new vibration vehicles.  In September of 2008, the Company entered into a loan agreement with a commercial lender to provide financing for the purchase of a new seismic recording system and equipment.  In December of 2008, we deployed our ninth seismic data acquisition crew along with our eighth new ARAM ARIES recording system.  During the second quarter of 2009, demand weakened and seismic market activity declined significantly in North America.  We responded to the weakening demand for seismic services by aggressively managing our costs, including our crew count, reducing TGC’s crews from a peak of nine crews in the first quarter of 2009 to four crews in the second half of the year in the U.S.  During October of 2009, we purchased Eagle Canada, Inc. a provider of seismic data services to the Canadian energy industry.  Following that acquisition, Eagle Canada operated two seismic crews for the remainder of 2009.  Eagle Canada utilizes the latest in Geospace GSR and ARAM ARIES recording equipment which is interchangeable with that of TGC. During 2010, an increase in the demand for seismic services allowed for an expansion of the Company’s crew count from six at December 31, 2009 to  eleven at December 31, 2010.

In June of 2010, the Company acquired a new 3,000 channel Geospace Seismic Recording System (“GSR System”). This new GSR System uses cable-free/radio-free autonomous nodal data recorders which have a built-in GPS and disciplined clock. The GSR System provides for up to 30 days of continuous data recording.  This system is fully compatible with our current ARAM recording equipment. In addition, our crews continue to utilize the state-of-the-art ARAM ARIES recording systems.  These systems employ cable telemetry technology enhanced by multiple baseline and redundant cable connections that provide seismic data acquisition services with increased reliability.

We currently own equipment for 14 land-based seismic data acquisition crews and 69 vibration vehicles.  Each crew consists of approximately 35 to 45 technicians with associated vehicles, geophones, a seismic recording system, energy sources, cables, and a variety of other equipment. Each ARAM crew has one central recording vehicle which captures seismic data. The GSR crews utilize a recorder to manage the data acquisition while the individual GSR System captures and holds the data until they are placed in the Data Transfer Module (“the DTM”).  The data is then transferred to a CD ROM or data tape which is delivered to a data processing center selected by the customer.

Capital Expenditures

We believe that it is essential to take advantage of advances in seismic technology and to commit capital to purchase and update our equipment cost-effectively. Purchasing and updating seismic equipment and technology involves a commitment to capital spending.  As a result, during the year ended December 31, 2010 capital expenditures of approximately $15,226,000 were used to acquire, maintain, and replace seismic equipment and vehicles. Major purchases included a new 3,000 channel GSR System.  The Company also purchased approximately 5,000 additional GSR channels and 8,500 additional ARAM channels. Because of the market downturn in 2009, we reduced capital expenditures for fiscal year 2009 to approximately $1,960,000, primarily for equipment and vehicle maintenance and replacement.  For fiscal year 2008, capital expenditures were approximately $21,686,000.

Customers and Consultants

Our customers are major and independent oil and natural gas exploration and development companies. The services we provide to our customers vary according to the size and needs of each customer.  Our services are marketed by supervisory and executive personnel who contact customers to determine their needs and respond to customer inquiries regarding the availability of crews. Contacts are based principally upon professional relationships developed over a number of years. There are many consultants in the oil and natural gas industry who process and interpret seismic data for oil and natural gas companies. These consultants can have a significant influence in determining which company their customers use to acquire seismic data.

During 2010, our largest customer accounted for approximately 15% of revenues.  During 2009, our largest customer accounted for approximately 31% of revenues.  During 2008, our two largest customers accounted for approximately  27% of revenues.

In order to avoid potential conflicts of interest with our customers, we do not participate in oil and natural gas ventures. The results of a seismic survey conducted for a customer belong to that customer. All of our customers’ information is maintained in strictest confidence.

Contracts

Our contracts are obtained either through competitive bidding or as a result of customer negotiations. Our services are conducted under general service agreements for seismic data acquisition services which define certain obligations for us and for our customers. A supplemental agreement setting forth the terms of a specific project, which may be cancelled by either party upon 30 days’ advance written notice, is entered into for every project. We currently operate under supplemental agreements that are either “turnkey” agreements providing for a fixed fee to be paid to us for each unit of data acquired or “term” agreements providing for a fixed hourly, daily, or monthly fee during the term of the project or projects.

Competition

The acquisition of seismic data for the oil and natural gas industry is a highly competitive business. There are approximately 81 seismic crews currently operating in the continental United States and Canada.  Contracts for such services generally are awarded on the basis of price quotations, crew experience, and the availability of crews to perform in a timely manner, although factors other than price, such as crew safety performance history and technological and operational expertise, are often determinative. Our competitors include companies with financial resources that are significantly greater than our own as well as companies of comparable and smaller size. Our primary competitors are Dawson Geophysical Company, Geokinetics, Inc. and CGG-Veritas.  In addition to the previously named companies, we also compete for projects from time to time with smaller seismic companies which operate in local markets with only one or two crews.

Employees

As of December 31, 2010, we employed a total of 804 full-time (non-union) employees, of which 29 consisted of management, sales, and administrative personnel with the remainder being crew and crew support personnel.  We believe our relationship with our employees to be satisfactory.

4

Data Bank

We own a data bank which contains gravity data, and to a lesser extent magnetic data, from many of the major oil and natural gas producing areas located within the United States. We do not have a seismic data bank. Our data bank information has been amassed through participatory surveys as well as speculative surveys historically funded by us alone. All data and interpretations may be licensed to customers at a fraction of the cost of newly acquired data. However, the licensing of this data is not a significant portion of our revenues.

Operating Risks and Insurance

Our business is subject to the hazards inherent in conducting seismic data acquisition activities in hostile environments with dangerous machinery, and in some instances explosives. These activities can cause personal injury or loss of life, damage to or destruction of property, equipment, the environment, and marine life, and suspension of operations.

In addition, we could be subject to personal injury or real property damage claims in the normal operation of our business. Such claims may not be covered by the indemnification provisions in our general service agreements to the extent that the damage is due to our negligence or intentional misconduct.

We do not carry insurance against certain risks that we could experience such as business interruption resulting from equipment maintenance or weather delays. We obtain insurance against certain property and personal casualty risks and other risks when such insurance is available and when our management considers it advisable to do so. Currently, our insurance coverage consists of employers’ liability with limits of $1,000,000 per accident and $2,000,000 in the aggregate, commercial general liability of $1,000,000 per accident and $2,000,000 in the aggregate, pollution liability of $1,000,000 per accident and $2,000,000 in the aggregate, and automobile liability with a $1,000,000 combined single limit, and a $10,000,000 umbrella policy. Our general service agreements require us to have specific amounts of insurance. There can be no assurance, however, that any insurance obtained by us will be adequate to cover any losses or liabilities, or that this insurance will continue to be available or available on terms which are acceptable to us. Liabilities for which we are not insured, or which exceed the policy limits of our applicable insurance, could have a material adverse effect on us.

ITEM 1A.  RISK FACTORS

Any investment in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below and the other information included in this Form 10-K before purchasing our common stock. Although the risks described below are the risks that we believe are material, they are not the only risks relating to our business and our common stock. Additional risks and uncertainties, including those that are not yet identified or that we currently believe are immaterial, may also adversely affect our business, financial condition, or results of operations. If any of the events described below occur, our business and financial results could be materially and adversely affected. The market price of our common stock could decline due to any of these risks, perhaps significantly, and you could lose part or all of your investment.

Company Risks

We may incur losses.

We reported a net loss of approximately $1,223,000 for the year ended December 31, 2010, compared to net income of approximately $1,880,000 and $6,898,000 reported for the years ended December 31, 2009 and 2008, respectively.  We also reported net income for the years ended December 31, 2007 and 2006.  Our ability to be profitable in the future will depend on many factors beyond our control, but primarily on the level of demand for land-based seismic data acquisition services by oil and natural gas exploration and development companies.  Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis.

5

The recent economic downturn could continue to adversely affect our revenues and cash flows.

The recent economic downturn could continue to adversely affect our revenues and cash flows if our customers, and/or potential customers, become unable to pay or must delay payment of, amounts owing to the Company because such customers are not successful in generating revenues or are precluded from securing necessary financing.

Our revenues and operating results can be expected to fluctuate from period to period.

Our revenues, operating results, and profitability may fluctuate from period to period. These fluctuations are attributable to the level of new business in a particular period, the timing of the initiation, progress, or cancellation of significant projects, higher revenues and expenses on our dynamite contracts, and costs we incur to train new crews we may add in the future to meet increased customer demand. Fluctuations in our operating results may also be affected by other factors that are outside of our control such as permit delays, weather delays, and crew productivity. Oil and natural gas prices  continued to be  volatile during the year ended December 31, 2010, and have resulted in demand fluctuations for our services. There can be no assurance of future oil and gas price levels or stability.  The demand for our services will be adversely affected by a significant reduction in oil and natural gas prices and by climate change legislation or material changes to U.S. energy policy.  Since our business has high fixed costs, the negative effect of one or more of these factors could trigger wide variations in our operating revenues, EBITDA margin, and profitability from quarter to quarter, which factors render quarter-to-quarter comparisons unreliable as an indicator of performance.  Due to the factors discussed above, you should not expect sequential growth in our quarterly revenues and profitability.

We are dependent upon significant customers.

During 2010, our largest customer accounted for approximately 15% of revenues.  During 2009, our  largest customer accounted for approximately 31% of revenues.  During 2008 our two largest customers accounted for approximately 27% of revenues.  In the past we have derived a significant amount of our revenues from a small number of oil and natural gas exploration and development companies.  While our revenues are derived from a concentrated customer base, our significant customers vary between years.  If we lose one or more major customers in the future, or if one or more customers encounter financial difficulties, our business, financial condition, and results of operations could be materially and adversely affected.

We are dependent upon significant suppliers.

During 2010, no vendor accounted for more than 10% of our purchases.  During 2009, our two largest vendors accounted for approximately 22% and 10% of our purchases, respectively.  During 2008, no vendor accounted for more that 10% of our purchases.  If we lose one or more major vendors in the future, or if one or more vendors encounter financial difficulties, our business, financial condition, and results of operations could be materially and adversely affected.

We receive revenues from customers who engage consultants for processing and interpreting the seismic data we provide.

We receive revenues from customers who have engaged consultants to process and interpret the seismic data provided by us. Consultants can have a significant influence in determining which company its customers use to acquire seismic data. A consultant could recommend that its customers consider using other seismic companies.

We face intense competition in our business from companies with greater financial resources.

The seismic data acquisition services industry is a highly competitive business in the continental U.S. and Canada.  Our competitors include companies with financial resources that are significantly greater than our own as well as companies of comparable and smaller size.

6

We are subject to Canadian foreign currency exchange rate risk.

We conduct business in Canada which subjects us to foreign currency exchange rate risk.  Our results of operations and our cash flows could be impacted by changes in foreign currency exchange rates.

Technological change in our business creates risks of technological obsolescence and requirements for future capital expenditures. If we are unable to keep up with these technological advances, we may not be able to compete effectively.

Seismic data acquisition technologies historically have steadily improved and progressed, and we expect this progression to continue. Our strategy is to upgrade our seismic data acquisition equipment on a regular basis to maintain our competitive position. However, since we are in a capital intensive industry and have limitations on our ability to obtain the financing necessary to enable us to purchase state-of-the-art equipment, some of our competitors may be able to purchase newer equipment when we may not be able to do so.

We are dependent on our management team and key employees, and the loss of any of them could harm our business.

We have limited management depth with the result that the loss, whether by death, departure, or illness, of Wayne A. Whitener, our President and Chief Executive Officer, or other senior executives, could have a material adverse effect on the ability of management to continue operations at the same level of efficiency. We have key man insurance on the life of our President and Chief Executive Officer so that, in the event of his untimely death, we would receive insurance proceeds of $1,000,000 under this policy.

Certain members of our management team are not subject to employment or non-competition agreements and may leave our employment at any time.

Our President and Chief Executive Officer, and the President, the Vice President of Operations, and the Operations Manager of Eagle Canada, are subject to employment agreements and non-competition agreements.  Members of our management team that are not subject to employment or non-competition agreements could leave upon little or no notice which could have a material adverse effect on our management’s ability to continue operations at the same level of effectiveness. Additionally, the lack of non-competition agreements would allow these members of our management team to immediately begin working for one of our competitors upon the termination of their relationship with us. This could have a negative impact on our strategic plan and our relationships with customers.

We extend credit to our customers without requiring collateral, and a default by a customer could have a material adverse effect on our operating revenues.

We perform ongoing credit evaluations of our customers’ financial conditions and, generally, require no collateral from our customers. A default in payment from one of our large customers could have a material adverse effect on our operating revenues for the period involved.

Certain of our core assets are pledged as collateral for short term notes that require large monthly payments.

Certain assets that are critical to our operations, including three of our ARAM ARIES recording systems, 13 vibration vehicles, and a 5,000 channel Geospace GSR recording system, acquired in 2010, are pledged as collateral to our equipment lenders and commercial banks and could be subject to foreclosure in the event that we default on our indebtedness having 36 to 57 month terms.  We currently have debt obligations covering the purchase of this equipment that require monthly payments between approximately $80,000 and $103,000.  These debt obligations mature at various dates ranging from July of 2011 to December of 2013.  Any decline in our operations could inhibit our ability to make these substantial monthly payments. In view of the short terms of these notes, a failure to make the monthly payments on these notes could cause our lenders to foreclose quickly on the assets securing these notes.  The foreclosure on certain of our core assets securing these notes could severely limit our ability to continue operations.

7

We may be subject to liability claims that are not covered by our insurance.

Our business is subject to the general risks inherent in land-based seismic data acquisition activities. Our activities are often conducted in remote areas under dangerous conditions including the detonation of dynamite. These operations are subject to risks of injury to personnel and damage to equipment.  Our crews are mobile, and equipment and personnel are subject to vehicular accidents.  These risks could cause us to experience equipment losses, injuries to our personnel, and interruptions in our business.

In addition, we could be subject to personal injury or real property damage claims in the normal operation of our business.  Such claims may not be covered under the indemnification provisions contained in our general service agreements to the extent that the damage is due to our negligence or intentional misconduct.

We do not carry insurance against certain risks that could cause losses, including business interruption resulting from equipment maintenance or weather delays (see “Operating Risks and Insurance”).

Our general service agreements require us to have specific amounts of insurance. There can be no assurance, however, that any insurance obtained by us will be adequate to cover all losses or liabilities or that this insurance will continue to be available or available on terms which are acceptable to us. Liabilities for which we are not insured, or which exceed the policy limits of our applicable insurance, could have a materially adverse effect on us.

We are subject to the requirements of Section 404 of the Sarbanes-Oxley Act. If we are unable to maintain compliance with Section 404, or if the costs related to maintaining compliance are significant, our profitability, stock price, and results of operations and financial condition could be materially adversely affected.

If we are unable to maintain adequate internal controls in accordance with Section 404, as such standards are amended, supplemented, or modified from time to time, we may not be able to insure that we have effective internal controls over financial reporting on an ongoing basis in accordance with Section 404.  Failure to achieve and maintain effective internal controls could have a material adverse effect on our stock price.  In addition, a material weakness in the effectiveness of our internal control over financial reporting could result in an increased chance of fraud and the loss of customers, reduce our ability to obtain financing, and/or require additional expenditures to comply with these requirements, each of which could negatively impact our business, profitability, and financial condition.

Industry Risks

We and our customers may be adversely affected by the recent recession.

The recent recession could continue to have a material adverse effect on our financial results and proposed plan of operations and could lead to further significant fluctuations in the demand for and pricing of oil and gas.  Reduced demand and pricing pressures could adversely affect the financial condition and results of operations of our customers and their ability to purchase our services.  We are not able to predict the timing, extent, and duration of the economic cycles in the markets in which we operate.

We derive nearly all of our revenues from companies in the oil and natural gas exploration and development industry, a historically cyclical industry, with levels of activity that are significantly affected by the levels and volatility of oil and natural gas prices.

Any prolonged reduction in the overall level of exploration and development activities, whether resulting from changes in oil and natural gas prices or otherwise, could adversely impact us in many ways by negatively affecting:

·                  our revenues, cash flows, and profitability;

·                  our ability to maintain or increase our borrowing capacity;

8

·                  our ability to obtain additional capital to finance our business and the cost of that capital; and

·                  our ability to attract and retain skilled personnel whom we would need in the event of an upturn in the demand for our services.

Worldwide political, economic, and military events have contributed to oil and natural gas price volatility and are likely to continue to do so in the future. Depending on the market prices of oil and natural gas, oil and natural gas exploration and development companies may cancel or curtail their drilling programs, thereby reducing demand for our services. Oil and natural gas prices have been highly volatile historically and, we believe, will continue to be so in the future. Many factors beyond our control affect oil and natural gas prices including:

·                  the cost of exploring for, producing, and delivering oil and natural gas;

·                  the discovery rate of new oil and natural gas reserves;

·                  the rate of decline of existing and new oil and natural gas reserves;

·                  available pipeline and other oil and natural gas transportation capacity;

·                  the ability of oil and natural gas companies to raise capital;

·                  actions by OPEC (the Organization of Petroleum Exporting Countries);

·                  political instability in the Middle East and other major oil and natural gas producing regions;

·                  economic conditions in the U.S. and elsewhere;

·                  domestic and foreign tax policy;

·                  domestic and foreign energy policy including the ever increasing emphasis on alternative sources of energy;

·                  weather conditions in the U.S. and elsewhere;

·                  the pace adopted by foreign governments for the exploration, development, and production of their national reserves;

·                  the price of foreign imports of oil and natural gas; and

·                  the overall supply and demand for oil and natural gas.

The high fixed costs of our operations could result in operating losses.

Companies within our industry are typically subject to high fixed costs which consist primarily of depreciation (a non-cash item) and maintenance expenses associated with seismic data acquisition and equipment and crew costs. In addition, ongoing maintenance capital expenditures, as well as new equipment investment, can be significant. As a result, any extended periods of significant downtime or low productivity caused by reduced demand, weather interruptions, equipment failures, permit delays, or other causes could adversely affect the results of our operations.

Our operations are subject to delays related to obtaining land access rights of way from third parties which could affect our results of operations.

Our seismic data acquisition operations could be adversely affected by our inability to obtain timely right of way usage from both public and private land and/or mineral owners. Delays associated with obtaining such rights of way could negatively affect our results of operations.

9

Our business is subject to government regulation which may adversely affect our future operations.

Our operations are subject to a variety of federal, state, and provincial and local laws and regulations, including laws and regulations relating to the protection of the environment and archeological sites and those that may result from climate change legislation.  Canadian operations have been historically cyclical due to governmental restrictions on seismic acquisition during certain periods.  As a result, there is a risk that there will be a significant amount of unused equipment during those periods.  We are required to expend financial and managerial resources to comply with such laws and related permit requirements in our operations, and we anticipate` that we will continue to be required to do so in the future. Although such expenditures historically have not been material to us, the fact that such laws or regulations change frequently makes it impossible for us to predict the cost or impact of such laws and regulations on our future operations. The adoption of laws and regulations that have the effect of reducing or curtailing exploration and development activities by energy companies could also adversely affect our operations by reducing the demand for our services.

Risks Related To Our Common Stock

Our common stock has experienced, and may continue to experience, price volatility and low trading volume.

Our stock price is subject to significant volatility. Overall market conditions, including a decline in oil and natural gas prices and other risks and uncertainties described in this “Risk Factors” section and elsewhere in this Form 10-K, could cause the market price of our common stock to fall. The high and low sales prices of our common stock for the year ended December 31, 2010, were $ 4.64 and $ 2.82, respectively.

Our common stock is listed on the NASDAQ Stock Market LLC under the symbol “TGE.” However, daily trading volumes for our common stock are, and may continue to be, relatively small compared to many other publicly traded securities.  For example, during 2010 our daily trading volume was as low as 1,200 shares.  In addition, our common stock traded on the NYSE Amex (formerly the American Stock Exchange) under the symbol “TGE” from April 18, 2005, until November 5, 2007.  During this period of time our daily trading volume was as low as 1,600 shares.  It may be difficult for you to sell your shares in the public market at any given time at prevailing prices, and the price of our common stock may, therefore, be volatile.

Our officers and directors own a large percentage of our common stock, and they may exercise control over our business and affairs.

Our officers and directors as a group beneficially own approximately 31% of our common stock.  As a result, they will continue to be able to exercise significant influence, and in most cases control, over matters requiring shareholder approval, including the election of directors, changes to our charter documents, and significant corporate transactions.  This concentration of ownership makes it unlikely that any other holder or group of holders of our common stock will be able to affect the way we are managed or the direction of our business.  The continued concentrated ownership of our common stock will make it difficult for another company to acquire us and for you to receive any related takeover premium for your shares (unless the controlling group approves the acquisition).

Certain provisions of our Restated Articles of Incorporation may make it difficult for a third party to acquire us or may adversely impact your rights as a common shareholder.

Our Restated Articles of Incorporation contain provisions that require the approval of holders of 80% of our issued and outstanding shares before we can enter into a merger or other business combination or sell all or substantially all of our assets. Additionally, if we increase the size of our board from the current six to nine directors, we could be required to stagger our directors’ terms, and our directors could not be removed without approval of holders of 80% of our issued and outstanding shares. These provisions could discourage or impede a tender offer, proxy contest, or other similar transaction involving control of us.

In addition, our board of directors has the right to issue preferred stock upon such terms and conditions as it deems to be in the best interest of the Company. The terms of such preferred stock may adversely impact the dividend and liquidation rights of the common shareholders without the approval of the common shareholders.

10

We do not intend to pay cash dividends on our common stock in the foreseeable future, and therefore only appreciation of the price of our common stock will provide a return to our shareholders.

While there are currently no restrictions prohibiting us from paying dividends to our shareholders, we have not paid any cash dividends on our common stock in the past, and we do not anticipate paying any dividends in the foreseeable future. Payment of any cash dividends in the future, however, is in the discretion of our board of directors and will depend on our financial condition, results of operations, capital and legal requirements, and other factors deemed relevant by our board of directors. Earnings, if any, are expected to be retained to fund our future operations.  On May 14, 2010, and May 12, 2009, the Company paid 5% stock dividends to its shareholders.

ITEM 2. DESCRIPTION OF PROPERTY.

In January of 2006, we leased a 600 square foot facility in Houston, Texas, to be used as a sales office.  The monthly rent is currently $564.  In July of 2006, we entered into a lease for 7,269 square feet of office space located in Plano, Texas.  In September of 2006, we relocated our corporate offices to this facility, and in September of 2008 increased the size of this lease to 8,523 square feet of office space.  The monthly rent is currently $13,140.  In October of 2006, we leased an 800 square foot facility in Oklahoma City, Oklahoma, to be used as a sales office.  The current monthly rent is $665.  In September of 2008, we leased a 400 square foot facility is Pratt, Kansas, to be used as a permit office.  The current monthly rent is $500.  In November of 2008, we vacated our Plano repair, warehouse, and outdoor storage facilities and moved to a leased repair, warehouse, and outdoor storage facility in Denison, Texas.  The Denison, Texas, facility consists of one 5,000 square foot building, two 10,000 square foot adjacent buildings, and an outdoor storage area of approximately 60,500 square feet.  The monthly rent is currently $12,602. In April of 2010, we leased a 915 square foot office facility in Midland, Texas, to be used as a sales office. This monthly rent is currently $839.  Upon the acquisition of Eagle Canada, we assumed a lease entered into in August of 2008 for 3,030 square feet of office space located in Calgary, Alberta.  The monthly rent is currently $12,314.  In addition, Eagle Canada leases a 10,088 square foot facility, also located in Calgary, Alberta, that is used as a shop and warehouse.  Effective April of 2010, we entered into a lease agreement for this facility. The monthly rent is currently $8,043. Prior to this date this facility was leased on a month-to-month basis.  The Company is not responsible for insuring these facilities.  The conditions of these facilities are good, and we believe that these properties are suitable and adequate for our foreseeable needs.

ITEM 3. LEGAL PROCEEDINGS.

The Company is a defendant in various legal actions that arose or may arise out of the normal course of business.  In our opinion, none of these actions have or will result in any significant loss to us.

Market Prices

On April 18, 2005, we began trading on the NYSE Amex (formerly the American Stock Exchange) (“AMEX”) under our current trading symbol “TGE.”  On October 26, 2007, we announced that our board of directors approved the decision to switch the listing of our common stock from AMEX to the NASDAQ Global Select Market (“NASDAQ.”)  As a result, on November 6, 2007, our stock began trading on NASDAQ under the symbol “TGE.”

11

The following table shows the high and low sales prices reported for our common stock on NASDAQ.  On May 14, 2010, and May 12, 2009,  the Company paid 5% stock dividends to shareholders of record at the close of business on April 30, 2010, and April 28, 2009, respectively.  All prior share and per share amounts have been restated to reflect the stock dividends.

The number of shareholders of record of TGE’s common stock as of February 28, 2011, was 153.  Due to the number of shares held in nominee or street name, we believe that there are a significantly greater number of beneficial owners of our common stock.  As of such date, CEDE & CO. held 15,630,502 shares in street name.  On February 28, 2011, our common stock was quoted at a closing sales price of $6.70.

Executive Overview

The Company is a leading provider of seismic data acquisition services throughout the continental United States and Canada.  We currently operate thirteen seismic crews.  These seismic crews supply seismic data to companies engaged in the exploration and development of oil and natural gas on land and in land-to-water transition areas. Our customers rely on seismic data to identify areas where subsurface conditions are favorable for the accumulation of existing hydrocarbons, to optimize the development and production of hydrocarbon reservoirs, to better delineate existing oil and natural gas fields, and to augment reservoir management techniques.

13

We acquire geophysical data using the latest in 3-D survey techniques. We introduce acoustic energy into the ground by using vibration equipment or dynamite detonation, depending on the surface terrain and subsurface requirements. The reflected energy, or echoes, is received through geophones, converted into a digital signal at a multi-channel recording unit, and then transmitted to a central recording vehicle. Subsurface requirements dictate the number of channels necessary to perform our services. With our state-of-the-art seismic equipment, including computer technology and multiple channels, we acquire, on a cost effective basis, immense volumes of seismic data that when processed and interpreted produce more precise images of the earth’s subsurface. Our customers then use our seismic data to generate 3-D geologic models that help reduce finding costs and improve recovery rates from existing wells.

Currently, the seismic data acquisition industry is made up of a number of companies divided into two groups. The first group is made up of four publicly-traded companies with long operating histories which field numerous crews and work in a number of different regions and terrain.  This group includes us, Dawson Geophysical Company, Geokinetics, Inc. and CGG-Veritas. These companies field approximately 50% of the estimated 81 seismic crews currently operating in the continental U.S. and Canada.  The second group is made up of smaller companies who generally run one or two seismic crews and often specialize in specific regions or types of operation.

We provide our seismic data acquisition services primarily to onshore oil and natural gas exploration and development companies for use in the onshore drilling and production of oil and natural gas in the continental U.S. and Canada.  The main factors influencing demand for seismic data acquisition services in our industry are the level of drilling activity by oil and natural gas companies and the sizes of such companies’ exploration and development budgets, which, in turn, depend largely on current and anticipated future crude oil and natural gas prices and depletion rates.

Our customers are major and independent oil and natural gas exploration and development companies. The services we provide to our customers vary according to the size and needs of each customer. Our services are marketed by sales, supervisory, and executive personnel who contact customers to determine their needs and respond to customer inquiries regarding the availability of crews. Contacts are based principally upon professional relationships developed over a number of years. There are a number of consultants in the oil and natural gas industry who process and interpret seismic data for oil and natural gas companies. These consultants can have a significant influence in determining which company their customers use to acquire seismic data.

The acquisition of seismic data for the oil and natural gas industry is a highly competitive business. There are approximately 81 seismic crews currently operating in the continental United States and Canada.  Contracts for such services generally are awarded on the basis of price quotations, crew experience, and the availability of crews to perform in a timely manner, although factors other than price, such as crew safety performance history and technological and operational expertise, are often determinative. Our competitors include companies with financial resources that are significantly greater than our own as well as companies of comparable and smaller size. Our primary competitors are Dawson Geophysical Company, Geokinetics, Inc., and CGG-Veritas. In addition to the previously named companies, we also compete for projects from time to time with smaller seismic companies which operate in local markets with only one or two crews.  We believe that our long-term industry expertise, the customer relationships developed over our history, and our financial stability give us an advantage over most of our competitors in the industry.

Results of Operations

Year Ended December 31, 2010, Compared to Year Ended December 31, 2009

Revenues.  Our revenues were $108,318,801 for the year ended December 31, 2010, compared to $90,431,899 for the same period of 2009, an increase of 19.8%.  This increase was primarily attributable to the inclusion of revenue of Eagle Canada for the entire year of 2010 as compared with its revenue included for only the last two and one-half months of 2009.

14

Cost of services.  Our cost of services was $85,932,862 for the year ended December 31, 2010, compared to $65,379,612 for the same period of 2009, an increase of 31.4%.  This increase was attributable to several factors including the increase in revenues for the year ended December 31, 2010, as explained above, compared to the same period of 2009, the inclusion of Canadian operations, and lower margins in the U.S resulting from depressed demand and a more competitive pricing environment (especially in the first half of 2010).  As a percentage of revenues, cost of services was 79.3% for the year ended December 31, 2010, compared to 72.3% for the same period of 2009.

Selling, general, and administrative expenses.  SG&A expenses were $6,894,500 for the year ended December 31, 2010, compared to $5,522,939 for the same period of 2009, an increase of 24.8%.  This increase was primarily attributable to the inclusion of Eagle Canada for the entire year of 2010.  SG&A expense as a percentage of revenues was 6.4% for the year ended December 31, 2010, compared to 6.1% for the same period of 2009.

Depreciation and amortization expense.  Depreciation and amortization expense was $15,343,084 for the year ended December 31, 2010, compared to $14,621,237 for the same period of 2009, an increase of 4.9%.  This increase was primarily attributable to inclusion of our Canadian operations for the entire year of 2010 and depreciation and amortization expense associated with capital expenditures of approximately $15,226,000 since January 1, 2010.  Depreciation and amortization expense as a percentage of revenues was 14.2% for the year ended December 31, 2010, compared to 16.2% for the same period of 2009.

Income from operations.  Income from operations was $147,635 for the year ended December 31, 2010, compared to $4,908,111 for the same period of 2009.  This decrease was primarily attributable to strong market pricing pressure resulting from the recent recession, continuing uncertainty regarding the future energy policy in the United States and increases in costs of services, SG&A, and depreciation and amortization expenses.  EBITDA decreased $4,037,909 to $15,491,439 for the year ended December 31, 2010, from $19,529,348 for the same period of 2009, a decrease of 20.7%.  This decrease was primarily attributable to the decrease in net income and income tax expenses, partially offset by an increase in depreciation referred to immediately above.  For a definition of EBITDA, a reconciliation of EBITDA to net income, and discussion of EBITDA, see the section entitled “Non-GAAP Financial Measure” which follows.

Interest expense.  Interest expense was $790,417 for the year ended December 31, 2010, compared to $1,020,681 for the same period of 2009, a decrease of 22.6%.  This decrease was primarily attributable to reductions in debt partially offset by additional debt incurred during the second half of 2010 for the purchase of 5,000 additional GSR channels.

Income tax expense.  Income tax expense was $579,900 for the year ended December 31, 2010, compared to $2,007,811 for the same period of 2009, a decrease of 71.1%.  This decrease was primarily attributable to the decline in pre-tax income.  Income tax expense for the year ended December 31, 2010 reflects the impact of state taxes, net of federal benefit, and permanent tax differences, including share based compensation.  See Note I of Notes to Financial Statements.

Year Ended December 31, 2009, Compared to Year Ended December 31, 2008

Revenues.  Our revenues were $90,431,899 for the year ended December 31, 2009, compared to $86,769,742 for the same period of 2008, an increase of 4.2%.  This increase was attributable to several factors including strong revenue earnings during our first quarter of 2009, revenues earned by Eagle Canada during a portion of our fourth quarter, and the fact that approximately 41% of the revenues in the year ended December 31, 2009, were derived from shot-hole contracts compared with approximately 20% for the same period of 2008.  This increase was partially offset by revenue decreases during the second half of the year.  Shot-hole contracts typically generate higher revenues but lower gross margins than vibroseis contracts due to higher third party costs that are included in revenues and have little or no margin associated with them.

Cost of services.  Our cost of services was $65,379,612 for the year ended December 31, 2009, compared to $55,935,068 for the same period of 2008, an increase of 16.9%.  This increase was primarily attributable to the increase in revenues during the year ended December 31, 2009, compared to the same period of 2008, pricing pressures as a result of the industry wide slow-down, and higher third party costs associated with the additional shot-hole contracts in 2009 compared to 2008.  As a percentage of revenues, cost of services was 72.3% for the year ended December 31, 2009, compared to 64.5% for the same period of 2008.

15

Selling, general, and administrative expenses.  SG&A expenses were $5,522,939 for the year ended December 31, 2009, compared to $4,468,883 for the same period of 2008, an increase of 23.6%.  This increase was primarily attributable to the recording of a reserve on an accounts receivable of a slow paying customer and the inclusion of fourth quarter general and administrative expenses of Eagle Canada.  SG&A expense as a percentage of revenues was 6.1% for the year ended December 31, 2009, compared to 5.2% for the same period of 2008.

Depreciation and amortization expense.  Depreciation and amortization expense was $14,621,237 for the year ended December 31, 2009, compared to $13,911,124 for the same period of 2008, an increase of 5.1%.  This increase was primarily attributable to incremental fourth quarter depreciation and amortization expenses attributable to Eagle Canada, depreciation and amortization expense associated with capital expenditures of approximately $1,960,000 since January 1, 2009, and additions of new seismic recording equipment and vibration vehicles during the second half of 2008.  Depreciation and amortization expense as a percentage of revenues was 16.2% for the year ended December 31, 2009, compared to 16.0% for the same period of 2008.

Income from operations.  Income from operations was $4,908,111 for the year ended December 31, 2009, compared to $12,454,667 for the same period of 2008, a decrease of 60.6%.  This decrease was primarily attributable to strong market pricing pressure resulting from the recent recession and increases in costs of services, SG&A, and depreciation and amortization expenses.  EBITDA decreased $6,836,443 to $19,529,348 for the year ended December 31, 2009, from $26,365,791 for the same period of 2008, a decrease of 25.9%.  This decrease was primarily attributable to the decrease in net income and income tax expenses, partially offset by an increase in depreciation referred to immediately above.  For a definition of EBITDA, a reconciliation of EBITDA to net income, and discussion of EBITDA, see the section entitled “Non-GAAP Financial Measure” which follows.

Interest expense.  Interest expense was $1,020,681 for the year ended December 31, 2009, compared to $929,656 for the same period of 2008, an increase of 9.8%.  This increase was primarily attributable to additional debt incurred during the second half of 2008 for the purchase of our eighth ARAM ARIES seismic recording system, 7,000 additional channels, and 13 new vibration vehicles.

Income tax expense.  Income tax expense was $2,007,811 for the year ended December 31, 2009, compared to $4,626,569 for the same period of 2008, a decrease of 56.6%.  This decrease was primarily attributable to the decrease in income from operations, partially offset by an increase in the effect of permanent tax differences.  The effective tax rate for the year ended December 31, 2009, was 51.6% compared to 40.1% for the same period of 2008.  See Note I of Notes to Financial Statements.

Non-GAAP Financial Measure

We define EBITDA as net income plus expenses of interest, income taxes, depreciation, and amortization. We use EBITDA as a supplemental financial measure to assess:

·                  the financial performance of our assets without regard to financing methods, capital structures, taxes, or historical cost basis;

·                  our liquidity and operating performance over time and in relation to other companies that own similar assets and that we believe calculate EBITDA in a manner similar to us; and

·                  the ability of our assets to generate cash sufficient for us to pay potential interest expenses.

We also understand that such data is used by investors to assess our performance. However, EBITDA is not a measure of operating income, operating performance, or liquidity presented in accordance with U.S. General Accepted Accounting Principles (“GAAP”). When assessing our operating performance or our liquidity, you should not consider this data in isolation or as a substitute for our net income, cash flow from operating activities, or other cash flow data calculated in accordance with GAAP.  EBITDA excludes some, but not all, items that affect net income and operating income, and these measures may vary among other companies. Therefore, EBITDA as presented below may not be comparable to similarly titled measures of other companies. Further, the results presented by EBITDA cannot be achieved without incurring the costs that the measure excludes: interest, taxes, depreciation, and amortization.

The following table reconciles our EBITDA to our net income:

Liquidity and Capital Resources

Cash flows from operating activities.

Net cash provided by operating activities was $5,160,283 for the year ended December 31, 2010, compared to $20,698,122 for the same period of 2009.  The $15,537,839 decrease was principally attributable to a net loss of $1,222,682 in 2010, compared to net income of $1,879,619 for 2009, the timing of accounts receivable collections, the timing of billings and revenue recognition, and the mix of contracts.

Working capital decreased $3,601,746 to $13,693,888 as of December 31, 2010, from the December 31, 2009, working capital of $17,295,634.  This decrease was due primarily to a decrease in cash and cash equivalents of $12,431,646 and an increase in trade accounts payable of $5,134,794, partially offset by an increase in trade accounts receivable of $7,711,485, an increase in cost and estimated earnings in excess of billings on uncompleted contracts of $4,104,521, an increase in prepaid expenses and other of $951,578 and a decrease in billings in excess of costs and estimated earnings on uncompleted contracts of $1,591,924.

Cash flows used in investing activities.

Net cash used in investing activities was $8,055,970 for the year ended December 31, 2010, and $10,942,164 for the year ended December 31, 2009.  This $2,886,194 decrease was primarily due to the non-recurring use of $10,345,000 cash paid for our purchase of the stock of Eagle Canada in October of 2009, partially offset by an  increase in cash related capital expenditures during 2010 of $6,870,321.

Cash flows used in financing activities.

Net cash used in financing activities was $9,549,811 for the year ended December 31, 2010, and $8,367,479 for the year ended December 31, 2009.  The $1,182,332 increase was due primarily to an increase in principal payments on notes payable of $1,151,661.

Capital expenditures.

During the year ended December 31, 2010, capital expenditures of $15,225,578 were used to acquire seismic equipment and vehicles, replace similar equipment and vehicles, and to purchase a new 3,000 channel GSR System.  The Company also purchased approximately 5,000 additional GSR channels and 8,500 additional ARAM channels.  Cash of $8,220,293, notes of $4,975,110 from a commercial bank, and capital lease obligations from a vehicle leasing company of $2,030,175 were used to finance these acquisitions.  During March of 2011, the Company entered into an agreement to purchase 5 new vibration vehicles and 2,500 channels of GSR seismic recording equipment for a total purchase price of approximately $5,500,000 to be paid from existing cash.  The Company expects to take delivery of this equipment during April and May of 2011.  Although we do not budget for our capital expenditures, we may purchase additional equipment during 2011 as the demand for our services warrants.

17

Capital Resources

Historically, we have relied on cash generated from operations, short-term borrowings from commercial banks and equipment lenders, and loans from directors to fund our working capital requirements and capital expenditures.

The Company has a revolving line of credit agreement with a commercial bank.  The borrowing limit under the revolving line of credit agreement is $5,000,000 and was renewed on  September 16, 2009, and again on September 16, 2010.  The revolving line of credit agreement does not expire until September 16, 2011.  Our obligations under this agreement are secured by a security interest in our accounts receivable and 2,000 channels of GSR System seismic recording equipment acquired in September of 2010.  Interest on the outstanding amount under the line of credit loan agreement is payable monthly at the greater of the prime rate of interest or five percent. The credit loan agreement currently provides for non-financial and financial covenants including  a ratio of debt to worth not in excess of 1.25 to 1.0.  As of December 31, 2010, we had no borrowings outstanding under the line of credit loan agreement.

In December of 2007, we completed a $4,120,254 loan transaction with a commercial lender for the purpose of providing funds for the purchase of our seventh new ARAM ARIES recording system. This loan is repayable over a period of 48 months at a fixed per annum interest rate of 6.38%.

The monthly rent is currently $8,043. Prior to this date this facility was leased on a month-to-month basis.  The Company is not responsible for insuring these facilities.  The conditions of these facilities are good, and we believe that these properties are suitable and adequate for our foreseeable needs.

Contractual Obligations

The following table summarizes payments due in specific periods related to our contractual obligations as of December 31, 2010:

(1)          See “Capital Resources” above for a discussion of the contractual obligations we have incurred since December 31, 2010.

We believe that our capital resources, including our short-term investments, funds available under our line of credit loan agreement, and cash flow from operations, are adequate to meet our current operational needs. We believe that we will be able to finance our 2011 capital expenditures through cash flow from operations, borrowings from commercial lenders, and the funds available under our line of credit loan agreement.  However, our ability to satisfy working capital requirements, meet debt repayment obligations, and fund future capital requirements will depend principally upon our future operating performance which is subject to the risks inherent in our business.

Off-Balance Sheet Arrangements

As of December 31, 2010, we had no off-balance sheet arrangements.

Critical Accounting Policies

The preparation of our financial statements in conformity with GAAP requires us to make certain assumptions and estimates that affect the reported amounts of assets and liabilities at the date of our financial statements and the reported amounts of revenues and expenses during the reporting period. Because of the use of assumptions and estimates inherent in the reporting process, actual results could differ from those estimates.

Revenue Recognition

Seismic Surveys

The Company provides seismic data acquisition survey services to its customers under general service agreements which define certain obligations for the Company and for its customers.  A supplemental agreement setting forth the terms of a specific project, which may be cancelled by either party upon 30 days’ advance written notice, is entered into for every project.  These supplemental agreements are either “turnkey” agreements providing for a fixed fee to be paid for each unit of seismic data acquired or “term” agreements providing for a fixed hourly, daily, or monthly fee during the term of the project.  The duration of these projects will vary from a few days to several months.  The Company recognizes revenue when services are performed under both types of agreements.  Services are defined as the commencement of data acquisition.  Under turnkey agreements, the total number of units of seismic data to be gathered is set forth in the agreement.   TGC recognizes revenue on turnkey agreements  as services are performed on a per unit of seismic data acquired rate.  Eagle Canada recognizes revenue on turnkey agreements as services are performed on a per unit of seismic data laid-out rate, which is standard industry practice in Canada. Under term agreements, revenue is recognized, by both TGC and Eagle Canada, as services are performed based on the time worked rate provided in the term agreement.  Under both turnkey and term agreements, cost of earned revenue is recognized by multiplying total estimated agreement cost by the percentage-of-completion of the agreement.  The excess of that amount over the cost of earned revenue reported in prior periods is recognized as cost of earned revenue for the period.  Agreements are not segmented nor combined for purposes of calculating percentage of completion.  The asset “Costs and estimated earnings in excess of billings on uncompleted contracts” represents cost incurred on turnkey agreements in excess of billings on those agreements.  The liability “Billings in excess of costs and estimated earnings on uncompleted contracts” represents billings on turnkey agreements in excess of cost on those agreements.  Claims have been negligible in the years ended December 31, 2010, 2009, and 2008.

Gravity Data

The Company owns a data bank which contains gravity data, and to a lesser extent magnetic data, from many of the major oil and natural gas producing areas located within the U.S.  When an order for gravity data is received, the portion of gravity data requested by the customer is prepared in digital format for licensing and shipment to the customer.  This process is performed by an employee in the Company’s headquarters office and normally takes no longer than a few days.  The licensing of gravity data is not a material part of the Company’s revenue.  Gravity data revenue during the years ended December 31, 2010, 2009, and 2008,  was approximately $24,000, $20,300, and $46,100,  respectively.

Business Combinations

We allocate the purchase price of acquired companies to the tangible assets acquired, liabilities assumed, and intangible assets acquired, based on their estimated fair values. The excess of the purchase price over these fair values is recorded as goodwill. We engage independent third-party appraisal firms to assist us in determining the fair values of assets acquired and liabilities assumed. Such valuations require management to make significant estimates and assumptions.

Allowance for Doubtful Accounts

We prepare our allowance for doubtful accounts receivable based on our past experience of historical write-offs, our current customer base, and our review of past due accounts. The inherent volatility of the energy industry’s business cycle can cause swift and unpredictable changes in the financial stability of our customers.  In the fourth quarter of 2009, we recorded an allowance against the account of a slow paying customer.  In the third quarter of 2010, this allowance was reversed because we determined an allowance was no longer required.

20

Impairment of Long-lived Assets

We review long-lived assets for impairment when triggering events occur suggesting deterioration in the assets’ recoverability or fair value. Recognition of an impairment charge is required if future expected net cash flows are insufficient to recover the carrying value of the asset. Our forecast of future cash flows used to perform impairment analysis includes estimates of future revenues and profitability based on our historical results and analysis of future oil and natural gas prices which are fundamental to assessing demand for our services. If we are unable to achieve these cash flows, our estimates will be revised which could result in an impairment charge for the period of revision.

Depreciable Lives of Property, Plant, and Equipment

Our property, plant, and equipment are capitalized at historical cost and depreciated over the useful life of the asset. Our estimate of this useful life is based on circumstances that exist in the seismic industry and information available at the time of the purchase of the asset. The technology of the equipment used to gather data in the seismic industry has historically evolved such that obsolescence does not occur quickly. As circumstances change and new information becomes available, these estimates could change. We amortize these capitalized items using the straight-line method. Capital assets are depreciated over their useful lives ranging from one to seven years, depending on the classification of the asset.

Tax Accounting

We account for our income taxes in accordance with the recognition of amounts of taxes payable or refundable for the current year and an asset and liability approach in recognizing the amount of deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our financial statements or tax returns. We determine deferred taxes by identifying the types and amounts of existing temporary differences, measuring the total deferred tax asset or liability using the applicable tax rate, and reducing the deferred tax asset by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Our methodology for recording income taxes requires judgment regarding assumptions and the use of estimates, including determining our annual effective tax rate and the valuation of deferred tax assets, which can create a variance between actual results and estimates and could have a material impact on our provision or benefit for income taxes.

Stock Based Compensation

We recognize the fair value of the stock-based compensation awards, including stock options and restricted stock, as wages in the consolidated statements of earnings on a straight-line basis over the vesting period of the related stock options or restricted stock awards.  This has resulted in the recognition of compensation expense, relative to stock-based awards, in wages in the consolidated statements of earnings of approximately $508,000, or approximately $0.03 per share, for the year ended December 31, 2010, and $366,000, or approximately $0.02 per share, for the year ended December 31, 2009.

Shares of restricted stock were issued to employees of the Company under the 2006 Stock Awards Plan as follows:  18,900 in August of 2007; 10,000 in June of 2008; 5,000 in July 2009; and 5,000 in May of 2010.  In addition, stock options were issued to employees of the Company under the 2006 Stock Awards Plan as follows:  335,000 in October of 2008 and 135,000 in November of 2009.  No stock options were granted to employees in 2010.  As of December 31, 2010, there was approximately $334,500 of unrecognized compensation expense related to our  share-based compensation plan.

Recently Issued Accounting Pronouncements

In July 2010, the FASB issued accounting standard update (“ASU”) 2010-20, “Receivables — Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses”.  ASU 2010-20 amends Topic 310 to improve the disclosures that an entity provides about the credit quality of its financing receivables and the related allowance for credit losses.  As a result of these amendments, an entity is required to disaggregate by portfolio segment or class certain existing disclosures and provide new disclosures about certain financing receivables and related allowance for credit losses. These provisions are effective for interim and annual reporting periods ending on or after December 15, 2010.  The adoption of this standard did not have a significant impact on our financial statements or disclosures.

21

Effect of Inflation

We do not believe that inflation has had a material effect on our business, results of operations, or financial condition during the past three years.

Information Regarding Forward-Looking Statements

This Form 10-K includes “forward-looking statements” as defined in Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which reflect our view with respect to future events.  We base these forward-looking statements on our current expectations and projections about future events.  These forward looking statements are subject to risks, uncertainties, and assumptions about the Company, including:

·                  dependence upon energy industry spending for seismic data acquisition services;

·                  the unpredictable nature of forecasting weather;

·                  the potential for contract delay or cancellation;

·                  the potential for fluctuations in oil and natural gas prices; and

·                  the availability of capital resources.

We use the words “may,” “will,” “can,” “could,” “should,” “expect,” “anticipate,” “estimate,” “believe,” “target,” “continue,” “intend,” “plan,” “budget,” and other similar words to identify forward-looking statements.  You should read statements that contain these words carefully because they discuss future expectations, contain projections of results of operations or of our financial condition, and/or state other “forward-looking” information.  We do not undertake any obligation to update or revise publicly any forward-looking statements, except as required by law.  These statements also involve risks and uncertainties that could cause our actual results or financial condition to differ materially from our expectations in this Form 10-K.

We believe that it is important to communicate our expectations of future performance to our investors.  However, events may occur in the future that we are unable to accurately predict or over which we have no control.  When considering our forward-looking statements, you should keep in mind the risk factors and other cautionary statements contained in this Form 10-K and other factors noted throughout this Form 10-K.  There are many risks, uncertainties, and events that may cause our actual results to differ materially from those contained in any forward-looking statement. Please read the section entitled “Risk Factors” for a discussion of certain risks of our business and an investment in our common stock.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We have not entered into any hedging agreements or swap agreements. Our principal market risk is the risk related to the concentration of our customers in the oil and natural gas industry. Since our customers are involved in the oil and natural gas industry, there may be a positive or a negative effect on our exposure to credit risk in that our customers may be similarly affected by changes in economic and industry conditions. For the year ended December 31, 2010, our largest customer accounted for approximately 15% of revenues.  For the year ended December 31, 2009, our top customer accounted for approximately 31% of our revenues.  For the year ended December 31, 2008, our top two customers accounted for approximately 27% of our revenues.  We conduct business in Canada which subjected us to a foreign currency exchange rate risk.  Our results of operations and our cash flows could be impacted by changes in foreign currency exchange rates.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders

TGC Industries, Inc. and Subsidiary

We have audited the accompanying consolidated balance sheets of TGC Industries, Inc. and Subsidiary (“the Company”) as of December 31, 2010 and 2009, and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2010.  The Company’s management is responsible for these financial statements. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of TGC Industries, Inc. and Subsidiary as of December 31, 2010 and 2009, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2010, in conformity with accounting principles generally accepted in the United States of America.

We were not engaged to examine management’s assertion about the effectiveness of TGC Industries, Inc. and Subsidiary’s internal control over financial reporting as of December 31, 2010 included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting and, accordingly, we do not express an opinion thereon.
