Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SAExploration Holdings, Inc. NOTE 1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of the Business We are a full–service provider of seismic data acquisition, logistical support and processing services in North America, South America, Asia Pacific, West Africa and the Middle East to customers in the oil and natural gas industry. Our chief operating decision maker regularly reviews financial data by country to assess performance and allocate resources, resulting in the conclusion that each country in which we operate represents a reporting unit. As these reporting units are similar in terms of economic characteristics, nature of products, processes and type of customers, we have concluded that our seismic data contract services operations comprise one single reportable segment. Basis of Presentation Our unaudited condensed consolidated financial statements included herein include our accounts and those of our subsidiaries that are wholly–owned, controlled by us or a VIE where we are the primary beneficiary, and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, certain information and disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. We believe that the presentations and disclosures herein are adequate to make the information not misleading. The unaudited condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) for a fair presentation of the interim periods. The results of operations for the interim period are not necessarily indicative of the results of operations to be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in Item 8 of our Annual Report on Form 10–K/A for the year ended December 31, 2018. All intercompany accounts and transactions have been eliminated in consolidation. In the Notes to Unaudited Condensed Consolidated Financial Statements, all dollar and share amounts in tabulations are in thousands of dollars and shares, respectively, unless otherwise indicated. Recently Adopted Accounting Pronouncements On January 1, 2019, we adopted Accounting Standards Update (“ASU”) No. 2016–02, Leases ASU 2018–10, Codification Improvements to Topic 842, ASU 2018–11, Targeted Improvements, and 2019–01, Codification Improvements The new standards provide for certain practical expedients when adopting the new guidance. We have elected the practical expedient package outlined in ASU No. 2016–02 under which we can carryforward our previous classification of a lease as either an operating or capital lease, and we do not have to reassess previously recorded initial direct costs. Additionally, we made policy elections allowing us to exclude leases with original terms of 12 months or less from lease assets and liabilities and to not separate nonlease components from the associated lease component and instead account for both as a single lease component for all asset classes. We did not elect the practical expedient allowing us to use hindsight to determine the lease term and to assess any impairment of lease assets during the lookback period. The adoption of the new standards had a material impact on our unaudited condensed consolidated balance sheet, with the most significant being the recognition of operating lease right–of-use (“ROU”) assets and operating lease liabilities of $9.9 million and $9.9 million, respectively. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. The standard did not materially impact our unaudited condensed consolidated statement of operations and unaudited condensed consolidated statement of cash flows. New Accounting Standards to be Adopted No new accounting pronouncements issued or effective during the six months ended June 30, 2019 have had or are expected to have a material impact on our unaudited condensed consolidated financial statements.

RESTATEMENT OF PREVIOUSLY REPOR

RESTATEMENT OF PREVIOUSLY REPORTED UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS	6 Months Ended
	Jun. 30, 2019
Accounting Changes And Error Corrections [Abstract]
RESTATEMENT OF PREVIOUSLY REPORTED UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS	Background of the Restatement As previously disclosed, the SEC has been conducting an investigation of certain matters, including with respect to revenue recognition, accounts receivable and tax credits. The Department of Justice (the “DOJ”) is conducting a parallel investigation with the SEC. We have been cooperating and will continue to cooperate with the SEC and the DOJ in their investigations. On August 5, 2019, our Board of Directors (the “Board”) established a special committee of independent directors (the “Special Committee”) to oversee an internal investigation with respect to the SEC investigation and any related matters. In turn, the Special Committee engaged its own legal and forensic accounting advisors, in addition to certain consulting services providers. Also in August 2019, the Audit Committee undertook an assessment of the accuracy of our historical financial statements and related disclosures that were contained in previously filed periodic reports. On August 14, 2019, the Audit Committee and the Board concluded that our previously issued consolidated financial statements and financial information relating to each of the fiscal years ended December 31, 2015, 2016, 2017 and 2018 and our condensed consolidated financial statements for the quarters and year–to–date periods ended June 30, 2015 through March 31, 2019 (collectively, the “Non–Reliance Periods”) contained errors, should no longer be relied upon and should be restated, and that other financial information, any earnings releases, investor presentations or other communications related thereto covering the Non–Reliance Periods should also no longer be relied upon. The Audit Committee’s and the Board’s decision to restate our consolidated financial statements for the Non–Reliance Periods arose from our re–evaluation of our relationship with Alaskan Seismic Ventures, LLC (“ASV”), which had not been consolidated into our financial statements. In August 2019, we determined that ASV is a variable interest entity (“VIE”), that we had a controlling financial interest in ASV, and that we are the primary beneficiary of ASV, which, among other factors, required us to consolidate ASV during the Non-Reliance Periods in accordance with GAAP. The Special Committee’s investigation identified that Global Equipment Solutions LLC (“Global Equipment”), one of our vendors in 2015 and 2016, was formed by Brent Whiteley, our former Chief Financial Officer and General Counsel, and controlled by Mr. Whiteley and/or Jeff Hastings, our former Chief Executive Officer. In 2015 and 2016, we paid an aggregate of approximately $12.0 million to Global Equipment pursuant to the following agreements. In August 2011, we entered into an agreement (the “Transfer Agreement”) with NES, LLC (“NES”), pursuant to which NES retained a transfer fee (the “Transfer Fee”) in connection with the transfer of a customer contract from NES to us. NES is a legal entity that was previously owned and/or controlled by Mr. Hastings that we subsequently acquired in October 2011. The Transfer Fee was assigned to a separate legal entity controlled by Mr. Hastings prior to our acquisition of NES in October 2011 and was subsequently assigned to Global Equipment. The authenticity of the Transfer Agreement and the subsequent assignments of the Transfer Fee have not been confirmed. Furthermore, the foregoing arrangements and the obligation to pay the Transfer Fee to NES, Global Equipment and/or Mr. Hastings was not disclosed. The payments made to Global Equipment in satisfaction of the purported Transfer Fee were previously recorded as rental expense in 2015 and 2016. These amounts have now been reclassified in our consolidated statement of operations as loss from misappropriation of funds in 2015 and 2016. Of the approximately $12.0 million paid to Global Equipment, approximately $5.9 million was transferred through entities formed and/or controlled by Mr. Hastings and Mr. Whiteley to ASV as capital contributions in December 2015. This investment in ASV was not disclosed. ASV was formed as a seismic data library company in 2015, and the Company previously reported revenue from ASV of approximately $57.3 million in 2016 and approximately $83.8 million in 2015. The remaining approximately $6.1 million paid to Global Equipment was transferred to Mr. Hastings and Mr. Whiteley and/or to entities formed and/or controlled by them. These payments were not disclosed. The Special Committee’s investigation also identified the misappropriation of approximately $4.1 million by Mr. Whiteley from 2012 to 2019, which amount has been reclassified in our consolidated statement of operations as a loss from a misappropriation of funds for such periods. A portion of these funds were paid to RVI Consulting, Inc. (“RVI”), a legal entity owned and/or controlled by Mr. Whiteley. The payments made to RVI were not disclosed. The majority of the payments to RVI were previously recorded as legal and professional expenses in the prior periods. Effects of the Restatement As a result of the determination that ASV is a VIE, in which we have a controlling financial interest and are the primary beneficiary, we are consolidating ASV for all periods beginning in 2015. The consolidation of ASV as of December 31, 2018 resulted in a reduction of stockholders’ equity of approximately $34.0 million due to the consolidation and elimination of inter-company transactions. The assets of ASV consist of a seismic data library in Alaska for which we provided the seismic data acquisition services, tax credits received from the State of Alaska under the rebatable oil and gas production tax credit regime and cash on hand. The tax credits were recorded as a reduction in the value of the seismic data library as a reimbursement of the costs incurred to acquire the data library. ASV has no significant liabilities other than its payable to us for the seismic data acquisition services and has approximately $5.9 million in capital contributions as described above. As of June 30, 2019, considering the approximately $34.0 million reduction in stockholders equity discussed above, the consolidation of ASV resulted in a decrease in stockholders’ equity of approximately $0.2 million. We have reclassified certain items in our consolidated statement of operations as loss from a misappropriation of funds disclosed above, of which approximately $121 thousand, $273 thousand, $128 thousand and $361 thousand, respectively, are related to the misappropriation of funds by Mr. Whiteley in the three and six months ended June 30, 3019 and 2018, respectively. In addition, we are restating our consolidated financial statements to correct for unrelated material accounting errors in prior periods, including the following: Three Months Ended June 30, 2018 • In the three months ended June 30, 2018, we recorded an allowance for doubtful accounts of approximately $19.0 million against our accounts receivable related to ASV. The receivable was eliminated upon consolidated of ASV and the allowance for doubtful accounts was reversed. • We identified an error related to the recording of deferred taxes in our Colombia and Bolivia subsidiaries. Based upon our internal review of the decision to record a 100% valuation allowance in 2018 related to these subsidiaries, we determined that the factors leading to the full valuation allowance of the deferred tax assets were present in previous periods and were not appropriately considered. As of result of this error, we have decreased income tax expense by approximately $1.8 million in the three months ended June 30, 2018. Six Months Ended June 30, 2018 • In the six months ended June 30, 2018, we recorded an allowance for doubtful accounts of approximately $19.0 million against our accounts receivable related to ASV. The receivable was eliminated upon consolidation of ASV and the allowance for doubtful accounts was reversed. • We identified an error related to the recording of deferred taxes in our Colombia and Bolivia subsidiaries. Based upon our internal review of the decision to record a 100% valuation allowance in 2018 related to these subsidiaries, we determined that the factors leading to the full valuation allowance of the deferred tax assets were present in previous periods and were not appropriately considered. As a result of this error, we have decreased income tax expense by approximately $1.2 million in the six months ended June 30, 2018. • We also corrected a prior error related to Delaware Franchise Taxes as part of the restatement. In the first quarter of 2018, we settled a multiyear audit with the State of Delaware. As part of the restatement we have properly recorded the franchise expense in the proper periods resulting in a decrease to selling, general and administrative expense by $547 thousand. Along with restating our unaudited condensed consolidated financial statements to correct the errors discussed above, we corrected our weighted average shares outstanding (basic and diluted) to include penny warrants in the computation of loss per common share and we recorded adjustments for certain immaterial accounting errors and reclassifications related to the periods covered in this Form 10–Q. In connection with the restatement of our condensed consolidated financial statements in this Form 10–Q, management determined that material weaknesses exist in our internal control over financial reporting and that our disclosure controls and procedures were ineffective during the Non–Reliance Periods and as of June 30, 2019. For a description of the material weaknesses identified by management and management’s implemented and planned remediations for those material weaknesses, please see “Item 4. Controls and Procedures” of this Form 10-Q. The tables below summarize the effects of the restatement on our (i) unaudited condensed consolidated balance sheet at December 31, 2018; (ii) unaudited condensed consolidated statements of operations for the three months and six months ended June 30, 2018; and (iii) unaudited condensed consolidated statement of cash flows for the six months ended June 30, 2018. A summary of the effect of the restatement on the unaudited condensed consolidated statements of changes to stockholders’ deficit for the six months ended June 30, 2018 and the unaudited condensed consolidated statement of comprehensive income (loss) for the three months and six months ended June 30, 2018 are not presented because the impact to accumulated deficit and comprehensive income (loss) are reflected below in the unaudited condensed consolidated balance sheet summaries and unaudited condensed consolidated statements of operations summaries.

In the three months and six months ended June 30, 2019, we recorded interest expense of $1.5 million and $3.0 million, respectively, related to the 6% senior secured convertible notes due 2023 (the “2023 Notes”), of which $0.9 million and $1.8 million, respectively, related to contractual interest expense. The credit agreements and indentures for our credit facility, senior loan facility, 2023 Notes and 10% senior notes due 2019 (the “Senior Notes”) contain certain representations, warranties, covenants and other terms and conditions which are customary for agreements of these types. As previously disclosed, as a result of certain circumstances giving rise to, or occurring as a result of, the restatement, as of June 30, 2019, certain events of default had occurred under these agreements. We repaid in full the Senior Notes at maturity in September 2019. In September 2019, we entered into forbearance agreements with respect to our credit facility, senior loan facility and 2023 Notes, whereby the holders of the indebtedness thereunder agreed to refrain from exercising their rights and remedies with respect to events of default that have occurred and other potential defaults or events of default that may occur as further specified in the forbearance agreements until 5:00 p.m. (New York City time) on the earlier of (i) November 30, 2019 and (ii) the date the forbearance agreements otherwise terminated in accordance with their terms. The November 30, 2019 deadline was ultimately extended to February 7, 2020. On February 7, 2020, we entered into amendments and waivers to our credit facility, senior loan facility and the indenture governing the 2023 Notes to, among other things, waive existing events of default thereunder and amend certain covenants requiring us to deliver financial statements, reports, projections and other items thereunder.

Commitments And Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	On August 18, 2019, a purported stockholder, John Bodin (the “Class Action Plaintiff”), filed a putative class action lawsuit against us and certain former executive officers named therein (the “Class Action Defendants”) in the U.S. District Court for the Southern District of Texas captioned John Bodin v. SAExploration Holdings, Inc., et al. Case No. 4:19–cv–03089. The Class Action Plaintiff seeks to represent a class of stockholders who purchased or otherwise acquired our publicly traded securities from March 15, 2016 through August 15, 2019 (the “Covered Period”). The complaint generally alleges that the Class Action Defendants violated Sections 10(b) and 20(a) of the Exchange Act and SEC Rule 10b–5 by making false and misleading statements in our periodic reports filed with the SEC during the Covered Period. The complaint requests damages, including interest, and an award of reasonable costs and expenses, including counsel and expert fees. On September 6, 2019, a purported stockholder, M. Shane Hamilton (the “Derivate Plaintiff”), filed a stockholder derivative lawsuit against certain of our former and current executive officers and directors named therein (the “Derivative Defendants”) in the U.S. District Court for the District of Delaware captioned M. Shane Hamilton, derivatively on behalf of SAExploration Holdings, Inc., v. Jeff Hastings, et al. The derivative complaint generally alleges (i) breaches by the Derivative Defendants of their fiduciary duties as our directors and/or officers, (ii) unjust enrichment, (iii) waste of corporate assets, and (iv) violations of Section 14(a) of the Exchange Act. The derivative complaint seeks, among other things, relief (i) directing us and the Derivative Defendants to take actions to reform and improve our corporate governance and internal procedures, (ii) awarding us restitution from the Derivative Defendants, and (iii) awarding the Derivative Plaintiff’s costs and attorneys’ and experts’ fees. As previously disclosed, the SEC has been conducting an investigation of certain matters, including with respect to revenue recognition, accounts receivable, and tax credits. The DOJ is conducting a parallel investigation with the SEC. We have been cooperating and will continue to cooperate with the SEC and the DOJ in their investigations. The SEC and DOJ investigations are continuing, and we are currently unable to predict the eventual scope, duration or outcome of any potential SEC or DOJ legal action or other action or whether it could have a material impact on our financial condition, results of operations, or cash flow. The DOR is conducting an investigation with respect to our determination that ASV is a variable interest entity and related Alaska tax credit certificates. We have been cooperating, and will continue to cooperate, with the DOR in its investigation. The DOR investigation is continuing, and we are unable to predict the eventual scope, duration or outcome of any potential DOR legal action or other action or whether it could have a material impact on our financial condition, results of operations, or cash flow. In the ordinary course of business, we may be subject to legal proceedings involving contractual and employment relationships, liability claims and a variety of other matters. Although the results of these other legal proceedings cannot be predicted with certainty, we do not believe that the final outcome of these proceedings should have a material adverse effect on our business, results of operations, cash flows or financial condition. However, we cannot predict the occurrence or outcome of these proceedings with certainty, and if we are unsuccessful in these proceedings and any loss exceeds our available insurance, if any, this could have a material adverse effect on our results of operations.

Leases [Abstract]
LEASES	We have entered into various non–cancellable operating and finance lease agreements for certain of our offices, shop and warehouse facilities, equipment and vehicles. We determine if an arrangement is a lease, or contains a lease, at inception and record the leases in our unaudited condensed consolidated financial statements upon lease commencement, which is the date when the underlying asset is made available for use by the lessor. Our leases have remaining lease terms ranging from one year to eight years and often include options to extend the lease term for up to three years. Some of our leases also include options to terminate the lease prior to the end of the agreed upon lease term. For the majority of leases entered into during the current period, we have concluded it is not reasonably certain that we would exercise the options to extend the lease. Therefore, as of the lease commencement date, our lease terms generally do not include these options. We include options to extend the lease when it is reasonably certain that we will exercise that option. Lease expense for operating lease payments is recognized on a straight–line basis over the lease term. Certain operating leases provide for annual increases to lease payments based on an index or rate. We estimate the annual increase in lease payments based on the index or rate at the lease commencement date, for both our historical leases and for new leases commencing after January 1, 2019. Differences between the estimated lease payment and actual payment are expensed as incurred. Lease expense for finance lease payments is recognized as amortization expense of the finance lease ROU asset and interest expense on the finance lease liability over the lease term. The balances for the operating and finance leases where we are the lessee are presented on our unaudited condensed consolidated balance sheet as follows: Classification on Unaudited Condensed Consolidated Balance Sheet June 30, 2019 Assets: Operating lease right-of-use assets Operating lease right-of-use assets $ 7,902 Finance lease assets Property and equipment, net 766 Total lease assets $ 8,668 Liabilities: Current: Operating lease liabilities Operating lease liabilities $ 3,193 Finance lease liabilities Current portion of long-term debt and finance leases 806 Long-term - Operating lease liabilities Other long-term liabilities 4,807 Total lease liabilities $ 8,806 The components of lease expense on our unaudited condensed consolidated statement of operations are as follows: Three Months Ended Six Months Ended June 30, 2019 June 30, 2019 Operating lease expense: Operating lease expense (1) $ 1,324 $ 2,664 Finance lease expense: Amortization of leased assets $ 207 $ 428 Interest on lease liabilities 31 69 Total finance lease expense $ 238 $ 497 Total lease expense $ 1,562 $ 3,161 (1) Includes short–term leases and variable lease costs, both of which are immaterial. As of June 30, 2019, our operating leases and finance leases have weighted average remaining lease terms of 3.9 years and 0.9 years, respectively, and both our operating leases and finance leases have a weighted average discount rate of 13.0%.

Revenue From Contract With Customer [Abstract]
REVENUE FROM SERVICES	Deferred Costs on Contracts In some instances, we incur third party costs that directly relate to the contract to fulfill the contract obligations. These fulfillment costs are capitalized and a mortized consistent with how the related revenue is recognized. Changes in our deferred costs on contracts are as follows for the six months ended June 30: 2019 2018 (Restated) Balance at beginning of year $ 3,746 $ 1,780 Fulfillment costs incurred 5,821 5,039 Amortization of fulfillment costs (7,717 ) (6,330 ) Balance at end of period $ 1,850 $ 489 Deferred Revenue Typically, our mobilization services are paid by the customer at the beginning of the contract while the revenue is recognized as control transfers to the customer, which can result in deferred revenue. Normally all other revenue is billed as work progresses, which generally will not result in significant deferred revenue except in those cases where a large mobilization is required for the contract. Changes in our deferred revenue are as follows for the six months ended June 30: 2019 2018 (Restated) Balance at beginning of year $ 4,357 $ 1,477 Cash received, excluding amounts recognized as revenue from services 8,181 385 Amounts recognized as revenue from services (8,098 ) (1,862 ) Balance at end of period $ 4,440 $ — Disaggregated Revenue The following table disaggregates our revenue by major source: Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 (Restated) (Restated) North America $ 28,875 $ 4,760 $ 89,428 $ 32,439 South America 702 12,123 752 21,567 Asia Pacific (1) 59,960 — 92,412 — Total $ 89,537 $ 16,883 $ 182,592 $ 54,006 (1) Remaining Performance Obligations As of June 30, 2019, we had $109.1 million of remaining performance obligations. We expect to recognize revenue of approximately 62% of these performance obligations in 2019 and the remaining approximately 38% in 2020.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
EQUITY-BASED COMPENSATION	We grant various forms of equity–based compensation to our senior management and directors. These equity–based awards currently consist of restricted stock units (“RSUs”). In March 2019, we issued 0.5 million RSUs to our senior management, which vested 50% on April 12, 2019 and the remaining 50% will vest on January 29, 2021, and an additional 0.2 million RSUs, all of which vest on September 29, 2020. The fair value of the RSUs on the date of grant was $2.5 million. We recognized equity–based compensation costs of $1.6 million in each of the three months ended June 30, 2019 and 2018 and $2.4 million and $2.6 million in the six months ended June 30, 2019 and 2018, respectively. These costs are included in “Selling, general and administrative expenses” on our unaudited condensed consolidated statements of operations. As of June 30, 2019, we had $5.2 million of unrecognized equity–based compensation cost, which is expected to be recognized over a weighted average period of 1.6 years.

Income Tax Disclosure [Abstract]
INCOME TAXES	We record income taxes for interim periods based on an estimated annual effective tax rate. The estimated annual effective tax rate is recomputed on a quarterly basis and may fluctuate due to changes in forecasted annual operating income, positive or negative changes to the valuation allowance for net deferred tax assets, and changes to actual or forecasted permanent book to tax differences. Our effective tax rates were (118.1)% and 0.2% for the three months ended June 30, 2019 and 2018, respectively, and 131.1% and 0.2% for the six months ended June 30, 2019 and 2018, respectively. The changes in our effective tax rates and the primary reason why these effective tax rates differ from the applicable federal statutory rates are the fluctuations in earnings among the various jurisdictions in which we operate, increases in valuation allowances and foreign tax rate differentials.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets or liabilities. Level 2 refers to fair values determined based on quoted prices for similar assets or liabilities in active markets or inputs that are observable to the asset or liability, either directly or indirectly through market corroboration. Level 3 refers to fair values determined based on unobservable inputs used in the measurement of assets and liabilities at fair value. The estimated fair values of our financial instruments have been determined at discrete points in time based on relevant market information. Our financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and long–term debt. The carrying amounts of our financial instruments, other than our 2023 Notes and Senior Notes, approximate fair value because of the short–term nature of the items. As of June 30, 2019, the estimated aggregate fair values and aggregate carrying values of our 2023 Notes and Senior Notes were $62.2 million and $52.3 million, respectively. As of December 31, 2018, the estimated aggregate fair values and aggregate carrying values of our 2023 Notes and Senior Notes was $50.7 million $51.0 million, respectively. As our 2023 Notes are not actively traded, the fair value determination of the 2023 Notes is categorized as Level 3 as the valuation was based on valuation techniques when observable market data is not available. The fair value determination of our Senior Notes is categorized as Level 2 as this valuation used dealer quoted prices in active markets obtained from independent third–party sources.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	Mr. Hastings, our former Chief Executive Officer, Mr. Whiteley, our former Chief Financial Officer and General Counsel, and our former Vice President Finance were owners in Speculative Seismic Investments, LLC (“SSI”), which was a lender under our senior loan facility in the principal amount of $0.6 million. In February 2019, SSI assigned its entire principal amount to another unaffiliated lender in a private transaction. As of June 30, 2019, SSI is no longer a lender under our senior loan facility. As of June 30, 2019, Mr. Hastings is a lender under our credit facility in the principal amount of $0.5 million and a holder of our 2023 Notes in the principal amount of $1.0 million. Mr. Hastings has an ownership interest in Fairweather Science, LLC (“Fairweather Science”), a company that provides specialized environmental support services to clients in Alaska’s natural resource industry. In the three months ended June 30, 2019 and 2018, we did not record any expenses related to services provided by Fairweather Science. In the six months ended June 30, 2019, we recorded expenses of $31 thousand related to services provided by Fairweather Science, LLC.

In each of the three months ended June 30, 2019 and 2018, RVI billed us $0.1 million for legal and professional services. In the six months ended June 30, 2019 and 2018, RVI billed us $0.3 million and $0.4 million, respectively, for legal and professional services. These payments were determined to be a misappropriation of funds, and are included in misappropriation of funds on our unaudited condensed consolidated statements of operations.

SUBSEQUENT EVENTS

SUBSEQUENT EVENTS	6 Months Ended

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	In November 2019, we financed the purchase of property and equipment pursuant to a secured promissory note in the amount of $10.0 million. The note bears interest at a fixed rate equal to 7.0% per annum and matures on January 1, 2023. We also amended our credit facility, senior loan facility and the indenture governing the 2023 Notes to permit the purchase pursuant to the note. In November 2019, we consummated the sale of substantially all of our assets in Australia for up to $9.0 million (Australian), payable as follows: (i) $6.0 million (Australian) paid in cash at closing, (ii) $0.6 million (Australian) payable no later than 30 business days after closing and (iii) earnout payments based on the utilization of certain of these assets following the closing in an amount up to $3.0 million (Australian). The earnout payments will be paid over a two–year period and capped at $1.5 million (Australian) in each such year. Subject to certain conditions, we will receive a minimum earnout payment equal to $750 thousand (Australian) in each such year. We also amended our credit facility and senior loan facility to permit the sale and to allow us to retain up to $6.0 million (Australian) of the net proceeds received from the sale, instead of using such net proceeds to repay amounts owed under our credit facility and senior loan facility. In December 2019, we amended our credit facility to, among other things, (i) request and receive advances in the aggregate principal amount of $5.0 million (the “First Advance”); (ii) provide for the ability to request and receive additional advances in the aggregate principal amount of $5.0 million (the “Additional Advances”); and (iii) provide for the issuance of Series F warrants pursuant to a warrant agreement (the “Warrant Agreement”) exercisable for shares of our common stock. We then borrowed the entire amount of the First Advance to be used for additional working capital. Under the Warrant Agreement, subject to certain conditions, we will issue up to approximately 2.0 million Series F warrants (the “First Advance Warrants”) and may issue additional Series F warrants representing up to 10% of the issued and outstanding shares of our common stock, on a fully diluted basis as of the date of the Additional Advances (or approximately 2.3 million shares of our common stock as of the closing date), upon the issuance of the Additional Advances. Each Series F warrant entitles the holder thereof to purchase one share of our common stock at an initial exercise price of $.0001 per share. We have issued approximately 0.9 million First Advance Warrants and, upon approval by our shareholders, will issue the remaining First Advance Warrants. Our credit facility requires us to use our best efforts to obtain shareholder approval for the issuance of the Series F warrants. In January 2020, we and ASV sold certain seismic data and related assets for a purchase price payable as follows: (i) $14.5 million paid to us, on behalf of ASV and us, in cash on the closing date, (ii) $0.5 million paid to us in cash on the closing date, and (iii) earnout payments in an amount of up to $5.0 million to be paid to us, on behalf of ASV and us, based on the licensing fees related to the licensing of certain seismic data following the closing date in an amount in excess of $15.0 million of licensing fees. In connection with the sale, we and ASV also entered into an agreement (the “Sellers’ Agreement”) with respect to certain post–closing indemnification obligations. The Sellers’ Agreement also provides that we will receive all the proceeds paid or payable pursuant to the sale pursuant to clauses (i) and (iii) above, which proceeds will be credited by us towards outstanding amounts owed to us by ASV. We also amended our credit facility, senior loan facility and the indenture governing the 2023 Notes to permit the sale and transactions contemplated by the Sellers’ Agreement and to provide for the application of $14.5 million of the net proceeds received from the sale to reduce indebtedness under our credit facility. Following the sale, the balance of our tax credits receivable, net has been reduced to $2.7 million. As previously disclosed, as a result of certain circumstances giving rise to, or occurring as a result of, the restatement, certain events of default had occurred under our credit facility, senior loan facility, 2023 Notes and Senior Notes. We repaid in full the Senior Notes at maturity in September 2019. In September 2019, we entered into forbearance agreements with respect to our credit facility, senior loan facility and 2023 Notes, whereby the holders of the indebtedness thereunder agreed to refrain from exercising their rights and remedies with respect to events of default that have occurred and other potential defaults or events of default that may occur as further specified in the forbearance agreements until 5:00 p.m. (New York City time) on the earlier of (i) November 30, 2019 and (ii) the date the forbearance agreements otherwise terminated in accordance with their terms. The November 30, 2019 deadline was ultimately extended to February 7, 2020. On February 7, 2020, we entered into amendments and waivers to our credit facility, senior loan facility and the indenture governing the 2023 Notes to, among other things, waive existing events of default thereunder and amend certain covenants requiring us to deliver financial statements, reports, projections and other items thereunder. We evaluated subsequent events for appropriate accounting and disclosure through the date these unaudited condensed consolidated financial statements were issued and determined that there were no material items that required recognition or disclosure in our unaudited condensed consolidated financial statements, except as described above.

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Our unaudited condensed consolidated financial statements included herein include our accounts and those of our subsidiaries that are wholly–owned, controlled by us or a VIE where we are the primary beneficiary, and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, certain information and disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. We believe that the presentations and disclosures herein are adequate to make the information not misleading. The unaudited condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) for a fair presentation of the interim periods. The results of operations for the interim period are not necessarily indicative of the results of operations to be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in Item 8 of our Annual Report on Form 10–K/A for the year ended December 31, 2018. All intercompany accounts and transactions have been eliminated in consolidation. In the Notes to Unaudited Condensed Consolidated Financial Statements, all dollar and share amounts in tabulations are in thousands of dollars and shares, respectively, unless otherwise indicated.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements On January 1, 2019, we adopted Accounting Standards Update (“ASU”) No. 2016–02, Leases ASU 2018–10, Codification Improvements to Topic 842, ASU 2018–11, Targeted Improvements, and 2019–01, Codification Improvements The new standards provide for certain practical expedients when adopting the new guidance. We have elected the practical expedient package outlined in ASU No. 2016–02 under which we can carryforward our previous classification of a lease as either an operating or capital lease, and we do not have to reassess previously recorded initial direct costs. Additionally, we made policy elections allowing us to exclude leases with original terms of 12 months or less from lease assets and liabilities and to not separate nonlease components from the associated lease component and instead account for both as a single lease component for all asset classes. We did not elect the practical expedient allowing us to use hindsight to determine the lease term and to assess any impairment of lease assets during the lookback period. The adoption of the new standards had a material impact on our unaudited condensed consolidated balance sheet, with the most significant being the recognition of operating lease right–of-use (“ROU”) assets and operating lease liabilities of $9.9 million and $9.9 million, respectively. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. The standard did not materially impact our unaudited condensed consolidated statement of operations and unaudited condensed consolidated statement of cash flows.
New Accounting Standards to be Adopted	New Accounting Standards to be Adopted No new accounting pronouncements issued or effective during the six months ended June 30, 2019 have had or are expected to have a material impact on our unaudited condensed consolidated financial statements.

Accounting Policies [Abstract]
Fair Value of Financial Instruments	The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets or liabilities. Level 2 refers to fair values determined based on quoted prices for similar assets or liabilities in active markets or inputs that are observable to the asset or liability, either directly or indirectly through market corroboration. Level 3 refers to fair values determined based on unobservable inputs used in the measurement of assets and liabilities at fair value. The estimated fair values of our financial instruments have been determined at discrete points in time based on relevant market information. Our financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and long–term debt. The carrying amounts of our financial instruments, other than our 2023 Notes and Senior Notes, approximate fair value because of the short–term nature of the items.
