A savings certificate entitling the Entity (that is, bearer) to receive interest at an established maturity date, based upon a fixed interest rate. A certificate of deposit may be issued in any denomination. Certificates of deposit are generally issued by commercial banks and, therefore, insured by the FDIC (up to the prescribed limit). Certificates of deposit generally restrict holders from withdrawing funds on demand without the incurrence of penalties. Generally, only certificates of deposit with original maturities of three months or less qualify as cash equivalents. Original maturity means original maturity to the entity holding the investment. As a related example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents.

Summary of Significant Accounting Policies

|
| Summary of Significant Accounting Policies | 1. Summary of Significant Accounting Policies Organization and Nature of Operations Founded in 1952, the Company acquires and processes 2-D, 3-D and multi-component seismic data for its clients, ranging from major oil and gas companies to independent oil and gas operators as well as providers of multi-client data libraries. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Dawson Seismic Services Holdings, Inc. and Dawson Seismic Services ULC. All significant intercompany balances and transactions have been eliminated in consolidation. Cash Equivalents For purposes of the financial statements, the Company considers demand deposits, certificates of deposit, overnight investments, money market funds and all highly liquid debt instruments purchased with an initial maturity of three months or less to be cash equivalents. Allowance for Doubtful Accounts Management prepares its allowance for doubtful accounts receivable based on its review of past-due accounts, its past experience of historical write-offs and its current client base. While the collectability of outstanding client invoices is continually assessed, the inherent volatility of the energy industry’s business cycle can cause swift and unpredictable changes in the financial stability of the Company’s clients. Property, Plant and Equipment Property, plant and equipment is capitalized at historical cost and depreciated over the useful life of the asset. Management’s estimation 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. As circumstances change and new information becomes available, these estimates could change. Depreciation is computed using the straight-line method. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the balance sheet, and any resulting gain or loss is reflected in the results of operations for the period. Impairment of Long-Lived Assets Long-lived assets are reviewed 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 undiscounted net cash flows are insufficient to recover the carrying value of the assets and the fair value of the assets is below the carrying value of the assets. Management’s forecast of future cash flows used to perform impairment analysis includes estimates of future revenues and expenses based on the Company’s anticipated future results while considering anticipated future oil and natural gas prices which is fundamental in assessing demand for the Company’s services. If the carrying amounts of the assets exceed the estimated expected undiscounted future cash flows, the Company measures the amount of possible impairment by comparing the carrying amount of the assets to the fair value. No impairment charges were recognized for the years ended September 30, 2013, 2012 or 2011. Leases The Company leases certain equipment and vehicles under lease agreements. The Company evaluates each lease to determine its appropriate classification as an operating or capital lease for financial reporting purposes. Any lease that does not meet the criteria for a capital lease is accounted for as an operating lease. The assets and liabilities under capital leases are recorded at the lower of the present value of the minimum lease payments or the fair market value of the related assets. Assets under capital leases are amortized using the straight-line method over the initial lease term. Amortization of assets under capital leases is included in depreciation expense. Revenue Recognition Services are provided under cancelable service contracts. These contracts are either “turnkey” or “term” agreements. Under both types of agreements, the Company recognizes revenues when revenue is realizable and services have been performed. Services are defined as the commencement of data acquisition or processing operations. Revenues are considered realizable when earned according to the terms of the service contracts. Under turnkey agreements, revenue is recognized on a per unit of data acquired rate as services are performed. Under term agreements, revenue is recognized on a per unit of time worked rate as services are performed. In the case of a cancelled service contract, revenue is recognized and the client is billed for services performed up to the date of cancellation. The Company receives reimbursements for certain out-of-pocket expenses under the terms of the service contracts. Amounts billed to clients are recorded in revenue at the gross amount including out-of-pocket expenses that are reimbursed by the client. In some instances, clients are billed in advance of services performed. In those cases, the Company recognizes the liability as deferred revenue. As services are performed, those deferred revenue amounts are recognized as revenue. In some instances, the contract contains certain permitting, surveying and drilling costs that are incorporated into the per unit of data acquired rate. In these circumstances, these set-up costs that occur prior to initiating revenue recognition are capitalized and amortized as data is acquired. Stock-Based Compensation The Company measures all employee stock-based compensation awards, which include stock options, restricted stock and restricted stock units, using the fair value method and recognizes compensation cost, net of estimated forfeitures, in its financial statements. The Company records compensation expense as operating or general and administrative expense as appropriate in the Consolidated Statements of Operations on a straight-line basis over the vesting period of the related stock options or restricted stock awards. Income Taxes The Company accounts for income taxes by recognizing amounts of taxes payable or refundable for the current year and by using an asset and liability approach in recognizing the amount of deferred tax assets and liabilities for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Management determines 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 in effect for the year in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates of deferred tax assets and liabilities is recognized in income in the year of an enacted rate change. The deferred tax asset is reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized. Management’s methodology for recording income taxes requires judgment regarding assumptions and the use of estimates, including determining the annual effective tax rate and the valuation of deferred tax assets, which can create variances between actual results and estimates and could have a material impact on the Company’s provision or benefit for income taxes. The Company’s effective tax rates differ from the statutory federal rate of 35% for certain items such as state and local taxes, non-deductible expenses, discrete items, expenses related to share-based compensation that were not expected to result in a tax deduction and changes in reserves for uncertain tax positions.
Use of Estimates in the Preparation of Financial Statements Preparation of the accompanying 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. Because of the use of assumptions and estimates inherent in the reporting process, actual results could differ from those estimates. |

Due to the short-term maturities of cash and cash equivalents, trade and other receivables, other current assets, accounts payables and other current liabilities, the carrying amounts approximate fair value at the respective balance sheet dates. The carrying value of the Company’s Term Note and Second Term Note approximate their fair value due to the fact that the interest rates on the Term Note and Second Term Note are reset each month based on the prevailing market interest rate. The Company’s Third Term Note approximates its fair value based on a comparison with the prevailing market interest rate. Due to the short-term maturities of the Company’s investments in certificates of deposit, the carrying amounts approximate fair value at the respective balance sheet dates. The fair values of the Company’s notes payable and investments in certificates of deposit are Level 2 measurements in the fair value hierarchy. |

| Debt | 6. Debt The Company’s revolving line of credit loan agreement is with Western National Bank. The agreement was renewed June 2, 2013 under the same terms as the previous agreement. The agreement permits the Company to borrow, repay and reborrow, from time to time until June 2, 2015, up to $20.0 million based on the borrowing base calculation as defined in the agreement. The Company’s obligations under this agreement are secured by a security interest in its accounts receivable, equipment and related collateral. Interest on the facility accrues at an annual rate equal to either the 30-day LIBOR, plus two and one-quarter percent, or the Prime Rate, minus three-quarters percent, as the Company directs monthly, subject to an interest rate floor of 4%. Interest on the outstanding amount under the loan agreement is payable monthly. The loan agreement contains customary covenants for credit facilities of this type, including limitations on disposition of assets, mergers and reorganizations. The Company is also obligated to meet certain financial covenants under the loan agreement, including maintaining specified ratios with respect to cash flow coverage, current assets and liabilities and debt to tangible net worth. The Company was in compliance with all covenants including specified ratios as of September 30, 2013 and has the full line of credit available for borrowing. The Company has not utilized the revolving line of credit during the fiscal years ended September 30, 2013 or 2012. The Company’s credit loan agreement includes a term loan feature under which the Company has two outstanding term loans. These term loans were confirmed and brought under the renewed credit loan agreement in June 2013. On June 30, 2011, the Company entered into the First Term Note by obtaining $16,427,000 in financing for the purchase of Geospace Technologies GSR equipment. The Term Note is repayable over a period of 36 months at $485,444 per month plus any applicable interest in excess of 4%. Interest on the Term Note accrues at an annual rate equal to either the 30-day LIBOR, plus two and one-quarter percent, or the Prime Rate, minus three-quarters percent, as the Company directs monthly, subject to an interest rate floor of 4%, and otherwise has the same terms as the revolving line of credit. The Term Note is collateralized by a security interest in the Company’s accounts receivable, equipment and related collateral and matures with all outstanding balances due on June 30, 2014.
On May 11, 2012, the Company entered into the Second Term Note under its credit loan agreement. The Second Term Note allows the Company to borrow from time to time up to $15.0 million to purchase equipment. The outstanding principal under the Second Term Note is amortized over a period of 36 months. The Second Term Note bears interest at an annual rate equal to either the 30-day LIBOR, plus two and one-quarter percent, or the Prime Rate, minus three-quarters percent, as the Company directs monthly, subject to an interest rate floor of 3.75%, and otherwise has the same terms as the revolving line of credit. The Second Term Note is collateralized by a security interest in the Company’s accounts receivable, equipment and related collateral and matures with all outstanding balances due on May 2, 2015. On July 5, 2012, the Company borrowed $9,346,000 under the Second Term Note to purchase Geospace Technologies GSR recording equipment. See additional discussion in Note 17, “Subsequent Events” to the Consolidated Financial Statements included herein.

The Third Term Note is repayable over a period of 36 months at $28,980 per month and bears interest at an implied annual fixed rate of 3.84%. The Third Term Note is collateralized by a security interest in the DSS equipment and matures with all outstanding balances due on February 5, 2016. In the second quarter of fiscal 2012, the Company began leasing vehicles from Enterprise Fleet Management under capital leases. These capital lease obligations are payable in 36 to 60 monthly installments and mature between December 2014 and November 2017.

| Stock-Based Compensation | 7. Stock-Based Compensation At September 30, 2013, the Company had one stock-based compensation plan. The awards outstanding under this plan and the associated accounting treatment are discussed below.
In fiscal year 2007, the Company adopted the Dawson Geophysical Company 2006 Stock and Performance Incentive Plan (the “Plan”). The Plan provides for the issuance of up to 750,000 shares of authorized Company common stock which may be awarded to officers, directors, employees and consultants of the Company in various forms including options, common stock grants, restricted stock grants, restricted stock units and others. Stock option grant prices awarded under the Plan may not be less than the fair market value of the common stock subject to such option on the grant date, and the term of stock options shall extend no more than ten years after the grant date. Incentive Stock Options: The Company estimates the fair value of each stock option on the date of grant using the Black-Scholes option pricing model. The expected volatility is based on historical volatility of the Company’s stock. The expected term represents the average period that the Company expects stock options to be outstanding and is determined based on the Company’s historical experience. The risk free interest rate used by the Company as the discounting interest rate is based on the U.S. Treasury rates on the grant date for securities with maturity dates of approximately the expected term. As the Company has not historically declared dividends and does not expect to declare dividends in the near term, the dividend yield used in the calculation is zero. Actual value realized, if any, is dependent on the future performance of the Company’s common stock and overall stock market conditions. There is no assurance the value realized by an option holder will be at or near the value estimated by the Black-Scholes model. A summary of the Company’s employee stock options as of September 30, 2013, as well as activity during the year then ended is presented below.
No options were granted during fiscal years 2013, 2012 or 2011. The total intrinsic value of options exercised during fiscal years 2013, 2012 and 2011 was $518,000, $173,000, and $318,000, respectively. The total fair value of options vested during fiscal years 2013, 2012 and 2011 was $362,000, $362,000, and $362,000, respectively. A summary of the status of the Company’s nonvested stock option awards as of September 30, 2013 and changes during the year then ended is presented below.
Outstanding options at September 30, 2013 expire in December 2018 and have an exercise price of $18.91. There was no unrecognized compensation costs related to stock option awards as of September 30, 2013. Stock options issued under the Plan are incentive stock options. No tax deduction is recorded when options are awarded. If an exercise and sale of vested options results in a disqualifying disposition, a tax deduction for the Company occurs. For the years ended September 30, 2013, 2012 and 2011, there were no excess tax benefits from disqualifying dispositions.
Cash received from option exercises under all share-based payment arrangements during the years ended September 30, 2013, 2012 and 2011 was $608,000, $184,000 and $297,000, respectively. The Company recognized compensation expense associated with stock option awards of $62,000, $362,000 and $362,000 in fiscal years 2013, 2012 and 2011, respectively, which are included in operating or general and administrative expense as appropriate in the Consolidated Statements of Operations. Restricted Stock Awards: There were no restricted stock grants in 2013 or 2011. The Company granted 103,500 shares of restricted stock to employees in fiscal year 2012. The weighted average grant date fair value of restricted stock awards in fiscal year 2012 was $23.55. The fair value of the restricted stock granted equals the market price on the grant date and vests after three years. A summary of the status of the Company’s nonvested restricted stock awards as of September 30, 2013 and changes during the year then ended is presented below.
The Company recognized compensation expense related to restricted stock awards of $1,307,000, $883,000 and $1,123,000 in fiscal years 2013, 2012 and 2011, respectively, which are included in operating or general and administrative expense as appropriate in the Consolidated Statements of Operations. As of September 30, 2013, there was approximately $1,337,000 of unrecognized compensation cost related to nonvested restricted stock awards granted. This cost is expected to be recognized over a weighted average period of 1.69 years. Restricted Stock Units: Beginning in 2013, the Company began granting restricted stock units. The Company granted 2,000 restricted stock units to employees during fiscal year 2013. The weighted average grant date fair value of restricted stock units in fiscal year 2013 was $27.14. The fair value of restricted stock units equals the market price on the grant date. The Company recognized compensation expense related to restricted stock units of approximately $25,000 during 2013, which is included in operating or general and administrative expense as appropriate in the Consolidated Statements of Operations. As of September 30, 2013, there was approximately $29,000 of unrecognized compensation cost related to nonvested restricted stock units. This cost is expected to be recognized over a weighted average period of 0.81 years. Common Stock Awards: The Company granted common shares with immediate vesting to outside directors and employees in fiscal years 2013, 2012 and 2011:
The Company recognized expense of $403,000, $244,000 and $186,000 in fiscal years 2013, 2012 and 2011, respectively, as well as the related tax benefit associated with these awards in operating or general and administrative expense as appropriate in the Consolidated Statements of Operations. |

| Income Taxes | 10. Income Taxes The Company recorded income tax expense in the current year of $9,090,000, as compared to $5,403,000 and $439,000 in 2012 and 2011, respectively. Income tax expense from operations is comprised of the following:
The income tax provision differs from the amount computed by applying the statutory federal income tax rate to income (losses) from continuing operations before income taxes as follows:
The principal components of the Company’s net deferred tax liability are as follows:
At September 30, 2013, the Company had a gross NOL for U.S. federal income tax purposes of approximately $25,750,000. This NOL expires in 2031. The Company will carry forward the net federal NOL of approximately $9,012,000. The Company also had net state NOLs that will affect state taxes of approximately $802,000 at September 30, 2013. State NOLs will begin to expire in 2015. Carryback provisions are not allowed by all states, so the entire state NOLs give rise to a deferred tax asset. Several of these carryforwards are primarily available in states where the Company believes the assets cannot be deemed to be more likely than not realizable. Based on management’s belief that the net operating loss carryforwards are not realizable, a $278,000 valuation allowance was established to offset these deferred tax assets as of September 30, 2013. The Company also has Canadian deferred tax assets that will begin to expire in 2032. The Company has recorded a valuation allowance of $987,000 against the Canadian deferred tax asset because management believes it is currently not more likely than not to be realizable. The Company had no valuation allowances as of September 30, 2012. As of September 30, 2013, the Company did not recognize any liabilities for unrecognized tax benefits. All of the liabilities for unrecognized tax benefits totaling $161,000 lapsed in the statutes of limitations during fiscal 2012. The Company did not record any changes in prior year tax positions, current year tax positions or settlements with taxing authorities related to uncertain tax positions during fiscal 2013 or 2012. The Company’s practice is to recognize interest and penalties related to unrecognized tax benefits in income tax expense. There were no interest and penalties recognized in fiscal year 2013. In fiscal year 2012 and 2011, there were interest and penalties included in the Consolidated Statements of Operations of $(98,000) and $(11,000), respectively.

| Net Income (Loss) Per Share Attributable to Common Stock | 11. Net Income (Loss) per Share Attributable to Common Stock Net income (loss) per share attributable to common stock is calculated using the two-class method. The two-class method is an allocation method of calculating earnings (loss) per share when a company’s capital structure includes participating securities that have rights to undistributed earnings. The Company’s employees and officers that hold unvested restricted stock would be entitled to dividends if the Company were to pay dividends. The Company’s basic net income (loss) per share attributable to common stock is computed by reducing the Company’s net income by the net income allocable to unvested restricted stockholders that have a right to participate in undistributed earnings. The Company’s employees and officers that hold unvested restricted stock do not participate in losses because they are not contractually obligated to do so. Accordingly, no losses are allocated to these unvested restricted stockholders. The undistributed earnings are allocated based on the relative percentage of the weighted average shares of unvested restricted stock and the total of the weighted average common shares outstanding plus the weighted average unvested restricted stock shares. The basic net income (loss) per share attributable to common stock is computed by dividing the net income (loss) attributable to common stock by the weighted average shares outstanding. The Company’s dilutive net income (loss) per share attributable to common stock is computed by adjusting basic net income (loss) per share attributable to common stock by diluted income allocable to unvested restricted stock divided by weighted average diluted shares outstanding. A reconciliation of the basic and diluted earnings (loss) per share attributable to common stock is as follows:
The Company had a net loss in 2011. As a result, the numerator for diluted loss per share attributable to common stock is the same as for basic loss per share attributable to common stock and the denominator for diluted loss per share attributable to common stock is the same as the denominator for basic loss per share attributable to common stock for this period.
The following weighted average numbers of certain securities have been excluded from the calculation of diluted income (loss) per share attributable to common stock, as their effects would be anti-dilutive.

| Commitments and Contingencies | 13. Commitments and Contingencies From time to time, the Company is a party to various legal proceedings arising in the ordinary course of business. Although the Company cannot predict the outcomes of any such legal proceedings, management believes that the resolution of pending legal actions will not have a material adverse effect on the Company’s financial condition, results of operations or liquidity as the Company believes it is adequately indemnified and insured. The Company experiences contractual disputes with its clients from time to time regarding the payment of invoices or other matters. While the Company seeks to minimize these disputes and maintain good relations with its clients, the Company has in the past, and may in the future, experience disputes that could affect its revenues and results of operations in any period. The Company has non-cancelable operating leases for office space in Midland, Houston, Denver, Oklahoma City, Pittsburgh and Calgary, Alberta. The following table summarizes payments due in specific periods related to the Company’s contractual obligations with initial terms exceeding one year as of September 30, 2013.
Some of the Company’s operating leases contain predetermined fixed increases of the minimum rental rate during the initial lease term. For these leases, the Company recognizes the related expense on a straight-line basis and records deferred rent as the difference between the amount charged to expense and the rent paid. Rental expense under the Company’s operating leases with initial terms exceeding one year was $900,000, $805,000, and $717,000 for fiscal 2013, 2012 and 2011, respectively. As of September 30, 2013, the Company had unused letters of credit totaling approximately $580,000. The Company’s letters of credit principally back obligations associated with the Company’s self-insured retention on workers’ compensation claims. Effective in fiscal 2012, the Company was no longer self-insured for workers’ compensation claims after October 1, 2011. The unused letters of credit outstanding at September 30, 2013 are associated with workers’ compensation claims outstanding prior to October 1, 2011. |

Rights Agreement

|
| Rights Agreement | 14. Rights Agreement On July 8, 2009, the Board of Directors of the Company authorized and declared a dividend to the holders of record at the close of business on July 23, 2009 of one Right (a “Right”) for each outstanding share of the Company’s common stock. When exercisable, each Right will entitle the registered holder to purchase from the Company a unit consisting of one one-hundredth of a share (a “Fractional Share”) of Series A Junior Participating Preferred Stock, par value $1.00 per share, of the Company (the “Preferred Shares”), at a purchase price of $130.00 per Fractional Share, subject to adjustment (the “Purchase Price”). The description and terms of the Rights are set forth in a Rights Agreement (the “Rights Agreement”) effective as of the close of business on July 23, 2009 as it may from time to time be supplemented or amended between the Company and Computershare Shareowner Services LLC (formerly Mellon Investor Services LLC), as Rights Agent. The Rights Agreement replaced the previous rights plan that was originally adopted in 1999 which expired on July 23, 2009. Initially, the Rights are attached to all certificates representing outstanding shares of Common Stock. The Rights will only separate from the Common Stock and a “Distribution Date” will only occur, with certain exceptions, upon the earlier of (i) ten days following a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the outstanding shares of Common Stock, or (ii) ten business days following the commencement of a tender offer or exchange offer that would result in a person’s becoming an Acquiring Person. In certain circumstances, the Distribution Date may be deferred by the Board of Directors. The Rights are not exercisable until the Distribution Date and will expire at the close of business on July 23, 2019, unless earlier redeemed or exchanged by the Company as described below. In the event (a “Flip-In Event”) that a person becomes an Acquiring Person (except pursuant to a tender or exchange offer for all outstanding shares of Common Stock at a price and on terms that a majority of the directors of the Company who are not, and are not representatives, nominees, Affiliates or Associates of, an Acquiring Person or the person making the offer determines to be fair to and otherwise in the best interests of the Company and its shareholders (a “Permitted Offer”)), each holder of a Right will thereafter have the right to receive, upon exercise of such Right, a number of shares of Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a Current Market Price (as defined in the Rights Agreement) equal to two times the exercise price of the Right. Notwithstanding the foregoing, following the occurrence of any Triggering Event, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by or transferred to an Acquiring Person (or by certain related parties) will be null and void in the circumstances set forth in the Rights Agreement. However, Rights are not exercisable following the occurrence of any Flip-In Event until such time as the Rights are no longer redeemable by the Company as set forth below. In the event (a “Flip-Over Event”) that, at any time from and after the time an Acquiring Person becomes such, (i) the Company is acquired in a merger or other business combination transaction (other than certain mergers that follow a Permitted Offer), or (ii) 50% or more of the Company’s assets, cash flow or earning power is sold or transferred, each holder of a Right (except Rights that are voided as set forth above) shall thereafter have the right to receive, upon exercise, a number of shares of common stock of the acquiring company having a Current Market Price equal to two times the exercise price of the Right. Flip-In Events and Flip-Over Events are collectively referred to as “Triggering Events.” At any time until ten days following the first date of public announcement of the occurrence of a Flip-In Event, the Company may redeem the Rights in whole, but not in part, at a price of $0.01 per Right, payable, at the option of the Company, in cash, shares of Common Stock or such other consideration as the Board of Directors may determine. After a person becomes an Acquiring Person, the right of redemption is subject to certain limitations in the Rights Agreement. At any time after the occurrence of a Flip-In Event and prior to a person’s becoming the beneficial owner of 50% or more of the shares of Common Stock then outstanding or the occurrence of a Flip-Over Event, the Company may exchange the Rights (other than Rights owned by an Acquiring Person or an affiliate or an associate of an Acquiring Person, which will have become void), in whole or in part, at an exchange ratio of one share of Common Stock, and/or other equity securities deemed to have the same value as one share of Common Stock, per Right, subject to adjustment. Until a Right is exercised, the holder thereof, as such, will have no rights as a shareholder of the Company, including, without limitation, the right to vote or to receive dividends. |

Recently Issued Accounting Pronouncements In February 2013, the FASB issued ASU No. 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” that updated guidance related to disclosure of reclassification amounts out of accumulated other comprehensive income. The standard requires that companies present, either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. ASU 2013-02 was effective for the Company as of January 1, 2013. The adoption of this guidance did not have a material impact on the Company’s financial statements. |

Concentrations of Credit Risk

| Concentrations of Credit Risk | 16. Concentrations of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk at any given time may consist of cash and cash equivalents, money market funds and overnight investment accounts, short-term investments in certificates of deposit, trade and other receivables and other current assets. At September 30, 2013 and 2012, the Company had deposits with domestic and international banks in excess of federally insured limits. Management believes the credit risk associated with these deposits is minimal. Money market funds seek to preserve the value of the investment, but it is possible to lose money investing in these funds. The Company’s sales are to clients whose activities relate to oil and natural gas exploration and production. The Company generally extends unsecured credit to these clients; therefore, collection of receivables may be affected by the economy surrounding the oil and natural gas industry or other economic conditions. The Company closely monitors extensions of credit and may negotiate payment terms that mitigate risk. For the year ended September 30, 2013, sales to the Company’s largest client represented 19% of its revenues as compared to less than 10% of its revenues at September 30, 2012. The sales to the Company’s second largest client represented 17% of its revenues at September 30, 2013 as compared to less than 10% of its revenues at September 30, 2012. The remaining balance of the Company’s fiscal 2013 revenues was derived from varied clients and none represented 10% or more of its fiscal 2013 revenues. |

Subsequent Events On December 4, 2013, the Company entered into a new Multiple Advance Term Note dated as of December 2, 2013 (“Fourth Term Note”) under the credit loan agreement with Western National Bank. The Fourth Term Note allows the Company to borrow from time to time up to $10.0 million to purchase equipment. Per the agreement, the Company will be unable to receive an advance for the remainder of the $15.0 million balance of the Second Term Note. The outstanding principal under the Fourth Term Note will be amortized over a period of 36 months. The Fourth Term Note bears interest at an annual fixed rate equal to 3.16%, and otherwise has the same terms as the revolving line of credit. The Fourth Term Note is collateralized by a security interest in the Company’s accounts receivable, equipment and related collateral and matures with all outstanding balances due on December 2, 2016. On December 5, 2013, the Company borrowed the full amount of $10,000,000 under the Fourth Term Note to purchase Geospace Technologies GSX recording equipment. |

Summary of Significant Accounting Policies (Policies)
|
12 Months Ended |
|---|---|
|
Sep. 30, 2013
|
|
| Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Dawson Seismic Services Holdings, Inc. and Dawson Seismic Services ULC. All significant intercompany balances and transactions have been eliminated in consolidation. |
| Cash Equivalents | Cash Equivalents For purposes of the financial statements, the Company considers demand deposits, certificates of deposit, overnight investments, money market funds and all highly liquid debt instruments purchased with an initial maturity of three months or less to be cash equivalents. |
| Allowance for Doubtful Accounts | Allowance for Doubtful Accounts Management prepares its allowance for doubtful accounts receivable based on its review of past-due accounts, its past experience of historical write-offs and its current client base. While the collectability of outstanding client invoices is continually assessed, the inherent volatility of the energy industry’s business cycle can cause swift and unpredictable changes in the financial stability of the Company’s clients. |
| Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment is capitalized at historical cost and depreciated over the useful life of the asset. Management’s estimation 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. As circumstances change and new information becomes available, these estimates could change. Depreciation is computed using the straight-line method. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the balance sheet, and any resulting gain or loss is reflected in the results of operations for the period. |
| Impairment of Long-Lived Assets | Impairment of Long-Lived Assets Long-lived assets are reviewed 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 undiscounted net cash flows are insufficient to recover the carrying value of the assets and the fair value of the assets is below the carrying value of the assets. Management’s forecast of future cash flows used to perform impairment analysis includes estimates of future revenues and expenses based on the Company’s anticipated future results while considering anticipated future oil and natural gas prices which is fundamental in assessing demand for the Company’s services. If the carrying amounts of the assets exceed the estimated expected undiscounted future cash flows, the Company measures the amount of possible impairment by comparing the carrying amount of the assets to the fair value. No impairment charges were recognized for the years ended September 30, 2013, 2012 or 2011. |
| Leases | Leases The Company leases certain equipment and vehicles under lease agreements. The Company evaluates each lease to determine its appropriate classification as an operating or capital lease for financial reporting purposes. Any lease that does not meet the criteria for a capital lease is accounted for as an operating lease. The assets and liabilities under capital leases are recorded at the lower of the present value of the minimum lease payments or the fair market value of the related assets. Assets under capital leases are amortized using the straight-line method over the initial lease term. Amortization of assets under capital leases is included in depreciation expense. |
| Revenue Recognition | Revenue Recognition Services are provided under cancelable service contracts. These contracts are either “turnkey” or “term” agreements. Under both types of agreements, the Company recognizes revenues when revenue is realizable and services have been performed. Services are defined as the commencement of data acquisition or processing operations. Revenues are considered realizable when earned according to the terms of the service contracts. Under turnkey agreements, revenue is recognized on a per unit of data acquired rate as services are performed. Under term agreements, revenue is recognized on a per unit of time worked rate as services are performed. In the case of a cancelled service contract, revenue is recognized and the client is billed for services performed up to the date of cancellation. The Company receives reimbursements for certain out-of-pocket expenses under the terms of the service contracts. Amounts billed to clients are recorded in revenue at the gross amount including out-of-pocket expenses that are reimbursed by the client. In some instances, clients are billed in advance of services performed. In those cases, the Company recognizes the liability as deferred revenue. As services are performed, those deferred revenue amounts are recognized as revenue. In some instances, the contract contains certain permitting, surveying and drilling costs that are incorporated into the per unit of data acquired rate. In these circumstances, these set-up costs that occur prior to initiating revenue recognition are capitalized and amortized as data is acquired. |
| Stock-Based Compensation | Stock-Based Compensation The Company measures all employee stock-based compensation awards, which include stock options, restricted stock and restricted stock units, using the fair value method and recognizes compensation cost, net of estimated forfeitures, in its financial statements. The Company records compensation expense as operating or general and administrative expense as appropriate in the Consolidated Statements of Operations on a straight-line basis over the vesting period of the related stock options or restricted stock awards. |
| Income Taxes | Income Taxes The Company accounts for income taxes by recognizing amounts of taxes payable or refundable for the current year and by using an asset and liability approach in recognizing the amount of deferred tax assets and liabilities for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Management determines 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 in effect for the year in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates of deferred tax assets and liabilities is recognized in income in the year of an enacted rate change. The deferred tax asset is reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized. Management’s methodology for recording income taxes requires judgment regarding assumptions and the use of estimates, including determining the annual effective tax rate and the valuation of deferred tax assets, which can create variances between actual results and estimates and could have a material impact on the Company’s provision or benefit for income taxes. The Company’s effective tax rates differ from the statutory federal rate of 35% for certain items such as state and local taxes, non-deductible expenses, discrete items, expenses related to share-based compensation that were not expected to result in a tax deduction and changes in reserves for uncertain tax positions. |
| Use of Estimates in the Preparation of Financial Statements | Use of Estimates in the Preparation of Financial Statements Preparation of the accompanying 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. Because of the use of assumptions and estimates inherent in the reporting process, actual results could differ from those estimates. |
