ITEM 1.        DESCRIPTION OF BUSINESS.

     TGC Industries, Inc. ("TGC" or the "Company") is a Texas corporation
engaged in the geophysical service business, primarily conducting Three-D
("3-D") surveys for clients in the oil and gas business.  TGC's principal
business office is located at 1304 Summit Avenue, Suite 2, Plano, Texas
75074.  (Telephone: 972-881-1099).

History

     In April 1980, Supreme Industries, Inc., formerly ESI Industries,
Inc., ("Supreme") formed a wholly owned subsidiary that acquired certain
equipment, instruments, and related supplies of Tidelands Geophysical Co.,
Inc. ("Tidelands"), a Houston-based corporation that had been organized in
1967 and was engaged in the business of conducting seismic, gravity, and
magnetic surveys under contracts to companies in the exploration for oil
and gas.  In July 1986, Tidelands' name was changed to TGC Industries, Inc.
("TGC").  On June 30, 1986, the Board of Directors of Supreme and TGC
approved a spin-off whereby substantially all of the shares of TGC owned by
Supreme were distributed as a stock dividend to Supreme security holders.

     On July 30, 1993, TGC acquired, through a wholly owned subsidiary,
Chase Packaging Corporation ("Chase"), a specialty packaging business,
principally supplying products to the agricultural industry, through the
purchase of certain assets of the Chase Packaging division of Union Camp
Corporation.

     In June 1996, the Board of Directors of TGC approved the spin-off of
Chase, effective July 31, 1996, whereby all of the shares of Chase owned by
TGC were distributed as a stock dividend to the shareholders of TGC under
the terms of the spin-off transaction. Pursuant to the terms of the spin-
off, and following clearance by the Securities and Exchange Commission on
March 7, 1997, the holders of TGC's Common Stock and, on an as-if-converted
basis, the holders of TGC's Series C 8% Convertible Exchangeable Preferred
Stock received the dividend distribution of Chase Common Stock. Since July
31, 1996, Chase has operated as an independent company as a specialty
packaging business principally supplying products to the agricultural
industry.

     During July 1996, the Company issued 1,150,350 shares of Series C 8%
Convertible Exchangeable Preferred Stock in a private placement offering
with gross proceeds of approximately $5,800,000.

     The preferred stock sold in the private placement entitles the holder
to receive cumulative cash dividends as, when and if declared by the Board
of Directors at a rate of 8% per annum prior to any dividend or
distribution in cash or other property on any class or series of stock
junior to the preferred stock.  The dividends on the preferred stock are
payable as, when and if declared by the Board of Directors on January 1 and
July 1 of each year, commencing January 1, 1997.  The dividend on the
preferred stock is cumulative.
     
     From the proceeds of the private placement, TGC made a capital
contribution to Chase of $2,716,403 to facilitate the spin-off; and TGC
retained $2,000,000 for the purchase of state-of-the-art geophysical
recording equipment.  Under the terms of the spin-off, the effective date
of which was July, 31, 1996, TGC completed the spin-off of the business and
assets relating to the Chase operations, except TGC retained the Portland,
Oregon facility and canceled all inter-company debt owed by Chase to TGC. 
The distribution of Chase Stock was March 7, 1997.  On March 18, 1997, TGC
sold the Portland, Oregon facility for $2,430,000 and applied such proceeds
in satisfaction of the mortgage indebtedness with respect to such facility
and in satisfaction of a debt obligation owing by TGC to Chase to pay to
Chase any such proceeds in excess of the amount of the mortgage
indebtedness.

     As of July 31, 1996, the effective date of the spin-off, TGC
Industries, Inc.'s only business has been the geophysical service business,
primarily conducting Three-D ("3-D") surveys for clients in the oil and gas
business.  Since July 31, 1996, the Chase operation has been reported as
discontinued operations.

General Description of the Company's Business

Geophysical Business

     Since its formation, TGC has engaged in the domestic geophysical
services business principally through conducting seismic surveys and to a
lesser extent through sales of gravity information from the Company's Data
Bank to companies engaged in the exploration for oil and gas in the United
States.  Geophysics is the study of the structure and composition of the
earth's interior and involves the measuring and interpretation of the
earth's properties with appropriate instruments.  Such studies are
generally conducted by means of surveys performed by field crews employing
seismic, gravity, or magnetic instruments to acquire data that is then
interpreted by various means to obtain useful information for oil and gas
companies.  The two survey techniques used by the Company in acquiring
geophysical data are seismic and gravity.  Land seismic surveys are the
Company's principal method of data acquisition and are by far the most
widely used geophysical technique.  TGC's seismic crews use dynamite as the
primary energy source for such surveys.

     In July 1996, the Company purchased an Opseis Eagle 24-BIT 1500
channel recording system, cables and geophones for approximately
$2,900,000, using $2,000,000 from proceeds from the Company's preferred
stock private placement, a $750,000 equipment loan, and funds from internal
cash flow.  In late November 1996, the Company purchased a second 1000
channel Eagle system using the proceeds and trade-in from TGC's two older
systems along with equipment financing of $855,000 and internal cash flow. 
In 1997, TGC purchased an additional 1500 channels utilizing equipment
financing of $2,242,685.  At the present time, TGC is operating two Eagle
2000 channel crews.  The greater precision and improved subsurface
resolution obtainable from 3-D seismic data have enabled energy companies
in the U.S. to better evaluate important subsurface features.  The
processing and interpretation of seismic data acquired by TGC are
transmitted by the Company to data processing centers (not owned or
operated by the Company) designated by the clients for processing.

     The Company's Data Bank contains gravity data, and to a lesser extent
magnetic data, from many of the major oil and gas producing areas located
within the United States.  TGC does not have a seismic data bank.  Data
Bank information has been amassed through participatory surveys as well as
speculative surveys funded by TGC alone.  All data and interpretations may
be licensed to customers at a fraction of the cost of newly acquired data.

     As a service business, the Company's domestic geophysical services
business is not dependent upon the supply of raw materials or any other
products and, therefore, the Company does not have arrangements with any
raw material suppliers.

     The Company utilizes two seismic crews to perform its geophysical
services and, in any given period, these crews may generate a significant
portion of their respective revenues from one or more customers.  For the
year ended December 31, 1997, two customers accounted for thirty-one
percent (31%) and twenty eight percent (28%), of the Company's revenue,
respectively.  The Company enters into a general or master agreement with
each of its customers for the provision of geophysical services and a
supplementary agreement (which becomes a part of the general agreement)
with respect to each particular job that the Company performs for a
customer.  Under the terms of such agreements the Company generally
contracts to supply all personnel, transportation and equipment to perform
seismic surveys for a given prospect for a fixed price plus reimbursement
for certain third party charges.  The Company generally bills its customers
on a progressive basis over the term of the contract.  The Company is
generally obligated to maintain insurance against injury or damage to
persons or equipment arising from the performance of its services and to
indemnify its customers against all claims and liability arising therefrom. 
Management believes this insurance coverage is sufficient.

     Activity in the U.S. Geophysical Industry has increased with the
success and acceptance of 3-D surveys.  The improved cost effectiveness
gained from the data acquisition and processing of 3-D surveys has resulted
in increased profits for the U.S. operations of the major and independent
oil companies.  With these cost advantages and the uncertainty of foreign
operations, many of the major U.S. oil companies are increasing
participation in the domestic oil industry.

     Due to the recent acquisition of two state-of-the-art instruments by
the Company, management believes that TGC should experience an increase in
revenues and operating profits.  However, due to uncertainties related to
weather, the potential for contract delay or cancellation, and the
potential for fluctuations in oil and gas prices, there can be no
assurances that such improvement in revenue and operating profits can be
achieved.

     As of December 31, 1997, TGC employed 108 employees, supporting two
seismic crews with a total of 100 crewmembers and direct support members. 
The Company believes its relationship with its employees to be
satisfactory.

ITEM 2.   DESCRIPTION OF PROPERTY.

     The Company's headquarters are in leased facilities located in Plano,
Texas from which it conducts all its current operations.  These facilities
include 8,000 square feet of office and warehouse space and an outdoor
storage area of approximately 10,000 square feet.  The monthly rent is
$4,210.  This facility is used to house corporate offices and serves as the
headquarters for the geophysical business. The Company is not responsible
for insuring the facilities.  The condition of the Company's facilities is
good and TGC management believes that these properties are suitable and
adequate for the Company's foreseeable needs.
     
     In July 1996, the Company retained the Portland, Oregon facility from
the spin-off of the Company's wholly owned subsidiary, Chase Packaging
Corporation.  The facility is 88,000 square feet of office and
manufacturing space with outdoor resin silos and a parking lot.  Chase had
previously acquired the facility when Chase purchased certain assets of
Union Camp Corporation's packaging division in July 1993. On March 18,
1997, TGC sold the Portland, Oregon facility for $2,430,000 and applied
such proceeds in satisfaction of the mortgage indebtedness with respect to
such facility and in satisfaction of a debt obligation owing by TGC to
Chase to pay to Chase any such proceeds in excess of the amount of the
mortgage indebtedness.

ITEM 3.   LEGAL PROCEEDINGS.

     The Company is a defendant in various legal actions that arose out of
the normal course of business.  In the opinion of Management, none of the
actions will result in any significant loss to the Company.

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

     No matters were submitted by the Company, during the fourth quarter of
the fiscal year ended December 31, 1997, to a vote of the Company's
security holders, through the solicitation of proxies or otherwise.

                                  PART II

ITEM 5.   MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

The Company's Common Stock has traded on the NASDAQ SmallCap Market under
the symbol "TGCI" since September 25, 1994.

The number of shareholders of record of TGCI's Common Stock as of March 10,
1998, was 413.  Due to the number of shares held in nominee or street name,
the Company believes that there are a significantly greater number of
beneficial owners of its Common Stock.  As of such date, CEDE & CO. held
2,509,100 shares in street name.  On March 10, 1998, TGC's Common Stock was
quoted at a closing bid price of $1.125.  High and low bid prices of TGC's
Common Stock for the period of January 1, 1996, to December 31, 1997, were
as follows:

The above bid quotations were furnished to TGC by the National Quotation Bureau Dividends are payable on the Company's Common Stock at the discretion of the Board of Directors. In light of the working capital needs of the Company, it is unlikely that cash dividends will be declared and paid on the Company's Common Stock in the foreseeable future. ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITIONS AND RESULTS OF OPERATIONS. Results of operations Geophysical Operation (Continuing Operations) Revenues from continuing operations for the year ended December 31, 1997, increased 75% to $16,307,577 from revenue of $9,339,970 for the year ended December 31, 1996. Net earnings from continuing operations before dividend requirements on preferred stock was $1,306,039 for the year ended December 31, 1997. Included in the 1997 net earnings was a $170,000 income tax benefit. Net earnings from continuing operations before dividend requirements on preferred stock was $388,699 for the year ended December 31, 1996. EBITDA from continuing operations was $2,764,014 or $.19 per share on a fully diluted basis for the year ended December 31, 1997, compared with $1,267,472 or $.12 per share on a fully diluted basis for the year ended December 31, 1996. The increase in revenue was the result of the operation of state-of-the-art recording equipment which was acquired in the second half of 1996 for the full year of 1997. In addition, a diversified backlog which included seismic surveys with higher contract prices contributed to the increase in the 1997 revenue. TGC's cost of services, as a percentage of revenue, was 86.1% in 1997, compared with 86.5% in 1996. Selling, general and administrative expense, as a percentage of revenue, decreased from 8.7% in 1996 to 5.6% in 1997. Interest expense increased by $137,103 in 1997 when compared to 1996 primarily as a result of the financing of additional geophysical equipment in the first half of 1997 and the financing of geophysical equipment acquired in the second half of 1996. Non-cash charges for depreciation were $1,425,817 in 1997 compared with $813,718 in 1996. During 1997, TGC purchased approximately $3,900,000 of additional equipment to better serve our clients in their pursuit of Three-D ("3-D") seismic data acquisition. With this additional recording capacity, TGC's two crews are equipped with 24-Bit high resolution equipment capable of recording up to 4,000 channels. This additional equipment was financed with a combination of equipment-related financing, internal cash flow and insurance claim proceeds from the Company's equipment and business interruption insurance policies. For over thirty years TGC has successfully served the geophysical industry and TGC crews are under contract through August 1998. We are currently working on securing contracts for the last part of 1998. If the 1998 exploration budgets of oil and gas companies are reduced significantly due to low oil prices, TGC's revenues and earnings may be adversely affected. However, a large portion of the Company's current contract backlog is in natural gas exploration, which, due to higher natural gas prices than a year ago, may soften the adverse impact of lower oil prices. This report contains forward-looking statements which reflect the view of Company's management with respect to future events. Although management believes that the expectations reflected in such forward-looking statements are reasonable, it can give no assurance that such expectations will prove to have been correct. Important factors that could cause actual results to differ materially from such expectations are disclosed in the Company's Securities and Exchange Commission filings, and include, without limitation, the unpredictable nature of forecasting weather, the potential for contract delay or cancellation, and the potential for fluctuations in oil and gas prices. The forward-looking statements contained herein reflect the current views of the Company's management and the Company assumes no obligation to update the forward-looking statements or to update the reasons actual results could differ from those contemplated by such forward-looking statements. At December 31, 1997, the Company had net operating loss carry forwards of approximately $4,400,000 available to offset future taxable income, which expires at various dates through 2012. Discontinued Operations The operations of the Company's former wholly owned subsidiary, Chase Packaging Corporation ("Chase"), are reflected as discontinued operations in the Company's financial statements. The effective date of the spin-off of Chase was July 31, 1996, and the date of the distribution of Chase Packaging Corporation's stock was March 7, 1997. In addition, on March 18, 1997, TGC sold the Portland, Oregon manufacturing facility of Chase for approximately $2,430,000, and applied such proceeds in satisfaction of the mortgage indebtedness with respect to such facility and in satisfaction of a debt obligation owing by TGC to Chase to pay to Chase any such proceeds in excess of the amount of the mortgage indebtedness. Financial Condition Geophysical Operations (Continuing Operations) Cash of $2,426,320 was provided by continuing operations for the twelve months ended December 31, 1997, compared with cash provided by continuing operations of $2,446,450 for the same period of the prior year. The funds generated in the first twelve months of 1997 were primarily attributable to net earnings before non-cash depreciation charges for the Company's geophysical operation. Cash used in investing activities for 1997 was primarily for additions to equipment for geophysical field operations. In addition, during 1997, the Company financed the acquisition of geophysical equipment through a note payable and capital leases in the amounts of $1,366,029 and $876,656, respectively. Cash used in financing activities were primarily for the payment of dividends on the Company's Series C 8% Convertible Exchangeable Preferred Stock in the amount of $685,710 and principal payments on debt obligations in the amount of $951,384. Working capital deficit increased $962,358 to $2,247,887 from the December 31, 1996, balance of $1,285,529, primarily as a result of an increase in billings in excess of costs and estimated earnings on uncompleted contracts and debt incurred in the purchase of geophysical equipment. The Company's current ratio declined to .57 to 1.0 at December 31, 1997, compared to .65 to 1.0 at December 31, 1996. Stockholders' equity increased to $3,729,993 at December 31, 1997, from the December 31, 1996, balance of $3,017,306 due primarily to the net earnings of the Company. During the fourth quarter of 1997, to support future growth of the Company, a $1,000,000 revolving bank line of credit was secured from a major bank. The line of credit bears interest at prime plus 1.5%, is collateralized by equipment and accounts receivable and requires the maintenance of certain financial ratios. At December 31, 1997, TGC was in compliance with all the financial ratios. In July 1996, TGC closed the private placement of 8% Convertible Exchangeable Preferred Stock. TGC's geophysical operation received approximately $2,000,000 from the private placement and utilized the proceeds, together with outside financing of $750,000 and internally generated funds, to purchase a state-of-the-art geophysical 1500 channel recording system. The Company placed this system into service in early August 1996. In late November 1996, the Company purchased a second 1000 channel system using the proceeds and a trade-in from TGC's two older systems along with equipment financing of $855,000 and internal cash flow. This system was placed into service in December 1996. The Company anticipates that available funds, together with anticipated cash flows generated from future operations and amounts available under its revolving line of credit will be sufficient to meet the Company's cash needs during 1998. Discontinued Operations As previously discussed, the operations of Chase has been accounted for as a discontinued operation in the accompanying financial statements due to the July 31, 1996, spin-off of Chase to TGC shareholders.

The accompanying notes are an integral part of these statements. TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS December 31, 1997 and 1996 NOTE A - NATURE OF OPERATIONS TGC Industries, Inc. (TGC or the Company) is engaged in the domestic geophysical services business and primarily conducts seismic surveys and sells gravity data to companies engaged in exploration in the oil and gas industry. The operations of its former wholly-owned subsidiary, Chase Packaging Corporation (Chase), which manufactures woven paper mesh and polypropylene mesh fabric bags for agricultural and industrial use, are reflected as discontinued in the accompanying financial statements. (See Note C). NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Cash Equivalents The Company considers all highly liquid investments with original maturity dates of three months or less to be cash equivalents. Property and Equipment Property and equipment are stated at cost. Depreciation is provided using the straight-line method over the estimated useful lives of the individual assets. Income Taxes Deferred income taxes reflect the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for tax purposes. Stock-Based Compensation Statement of Financial Accounting Standards No. 123 (SFAS 123), "Accounting for Stock-Based Compensation" encourages, but does not require, companies to record compensation cost for stock- based employee compensation plans at fair value. The Company has chosen to continue to account for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board Opinion No. 25 (APB 25), "Accounting for Stock Issued to Employees" and provides the required pro forma disclosures prescribed by SFAS 123. TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1997 and 1996 NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Revenue Recognition Revenues from conducting seismic surveys are recognized over the term of the contract using the percentage-of-completion method. Under this method, revenues are recognized on the units-of-production method. Revenues for the sale of gravity data are recognized when services are rendered. Earnings (Loss) Per Share For the year ended December 31, 1997, the Company adopted Statement of Financial Accounting Standards No. 128 (SFAS 128), "Earnings Per Share." Under SFAS 128, basic earnings (loss) per common share is based upon the weighted average number of shares of common stock outstanding. Diluted earnings (loss) per share is based upon the weighted average number of common shares outstanding and, when dilutive, common shares issuable for stock options, warrants and convertible securities. Earnings (loss) per share data for 1996 has been restated to conform to the provisions of SFAS 128. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NOTE C - REORGANIZATION PLAN In May 1996, a formal plan was adopted to reorganize TGC and Chase. Pursuant to the plan, the following actions have been taken: (a) During July 1996, the Company issued 1,150,350 shares of Series C 8% convertible exchangeable preferred stock in a private placement offering with gross proceeds of approximately $5,800,000. The preferred stock is, at the option of the Company, exchangeable into 8% subordinated convertible debentures. The preferred TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1997 and 1996 NOTE C - REORGANIZATION PLAN - Continued stock and debentures are convertible into shares of the Company's common stock for a period of four years and are convertible in years one and two at $.75 per share, year three at $1.25 and thereafter at $2.00. (b) Upon closing of the private placement, the Company contributed $2,716,403 as a capital contribution to Chase. (c) TGC liquidated its wholly-owned subsidiary, Chase Packaging Corporation (Old Chase), with TGC receiving all of Old Chase's properties and liabilities in cancellation of the Old Chase stock held by TGC. TGC formed a new wholly-owned subsidiary, New Chase Corporation (New Chase), and subsequently changed the name to Chase Packaging Corporation. TGC transferred all of the properties and liabilities received in the liquidation of Old Chase to New Chase, except TGC retained the manufacturing facility of Old Chase located in Portland, Oregon. On March 18, 1997, TGC sold the facility for proceeds of approximately $2,400,000. TGC applied such proceeds in satisfaction of the mortgage indebtedness with respect to such facility and in satisfaction of a debt obligation owing by TGC to New Chase to pay to New Chase any such proceeds in excess of the amount of the mortgage indebtedness. (d) During June 1996, the Board of Directors approved the spin-off of New Chase whereby all of the shares of New Chase would be distributed as a stock dividend to the shareholders of TGC common stock and, on an as if converted basis, TGC preferred stock, effective July 31, 1996. The New Chase common stock was distributed on March 7, 1997. The spin-off distribution of New Chase to TGC stockholders reduced stockholders' equity by $103,976, which represents the book value of the net assets of New Chase as of March 7, 1997. TGC Industries, Inc. NOTES TO FINANCIAL STATEMENTS - CONTINUED December 31, 1997 and 1996 NOTE C - REORGANIZATION PLAN - Continued Accordingly, the operations of Chase have been classified as discontinued in the accompanying financial statements.

Options granted under the 1993 Plan must be exercised within five years from the date of grant. Options covering 180,000 shares are exercisable as follows: (i) one-third of the shares after the first twelve-month period following the date of grant, (ii) up to two-thirds of the shares after the first twenty-four month period following the date of grant, and (iii) all of the shares of stock subject to the option at any time after the first thirty-six month period following the date of grant.
