Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies Organization —Mitcham Industries, Inc., a Texas corporation (the “Company”), was incorporated in 1987. The Company, through its wholly owned subsidiary, Seamap International Holdings Pte, Ltd. (“Seamap”), and its wholly owned subsidiary, Klein Marine Systems, Inc. (“Klein”), designs, manufactures and sells a broad range of proprietary products for the seismic, hydrographic and offshore industries with product sales and support facilities based in New Hampshire, Singapore and the United Kingdom. The Company, through its wholly owned Australian subsidiary, Seismic Asia Pacific Pty Ltd. (“SAP”), provides seismic, oceanographic and hydrographic leasing and sales worldwide, primarily in Southeast Asia and Australia. The Company, through its wholly owned Canadian subsidiary, Mitcham Canada, ULC (“MCL”), its wholly owned Russian subsidiary, Mitcham Seismic Eurasia LLC (“MSE”), its wholly owned Hungarian subsidiary, Mitcham Europe Ltd. (“MEL”), its wholly owned Singaporean subsidiary, Mitcham Marine Leasing Pte. Ltd. (“MML”), and its branch operations in Colombia, provides full-service equipment leasing, sales and service to the seismic industry worldwide. All intercompany transactions and balances have been eliminated in consolidation. Revenue Recognition of Leasing Arrangements —The Company leases various types of seismic equipment to seismic data acquisition companies. All leases at January 31, 2018 , 2017 and 2016 are for one year or less. Lease revenue is recognized ratably over the term of the lease. The Company does not enter into leases with embedded maintenance obligations. The standard lease provides that the lessee is responsible for maintenance and repairs to the equipment, excluding normal wear and tear. The Company occasionally provides technical advice to its customers without additional compensation as part of its customer service practices. Repairs or maintenance performed by the Company is charged to the lessee, generally on a time and materials basis. Repair and maintenance revenue is recognized as incurred. Revenue Recognition of Equipment Sales —Revenues and cost of sales from the sale of equipment are recognized upon acceptance of terms and when delivery has occurred, unless there is a question as to collectability. In cases where the equipment sold is manufactured by others, the Company reports revenues at gross amounts billed to customers because the Company: (a) is the obligor in the sales arrangement; (b) has full latitude in pricing the product for sale; (c) has general inventory risk should there be a problem with the equipment being sold to the customer or if the customer does not complete payment for the items purchased; (d) has discretion in supplier selection if the equipment ordered is not unique to one manufacturer; and (e) assumes credit risk for the equipment sold to its customers. Revenue Recognition of Long-term Projects —From time to time, SAP and Klein enter into contracts whereby they assemble and sell certain marine equipment, primarily to governmental entities. Performance under these contracts generally occurs over a period of several months. Revenue and costs related to these contracts are accounted for under the percentage of completion method, based on estimated physical completion. Revenue Recognition of Service Agreements —Seamap provides on-going support services pursuant to contracts that generally have a term of 12 months . The Company recognizes revenue from these contracts over the term of the contract. In some cases, the Company will provide support services on a time and material basis. Revenue from these arrangements is recognized as the services are provided. For certain new systems that Seamap sells, the Company provides support services for up to 12 months at no additional charge. Any amounts attributable to these support obligations are immaterial. Revenues from service contracts for each of the three months ended January 31, 2018 were not material. Due to immateriality, service revenues are not presented separately in the financial statements. Contracts Receivable —In connection with the sale of seismic equipment, the Company will, from time to time, accept a contract receivable as partial consideration. These contracts bear interest at a market rate, generally have terms of less than two years and are collateralized by a security interest in the equipment sold. Interest income on contracts receivable is recognized as earned, unless there is a question as to collectability in which case it is recognized when received. Allowance for Doubtful Accounts —Trade receivables are uncollateralized customer obligations due under normal trade terms. The carrying amount of trade receivables and contracts receivable is reduced by a valuation allowance that reflects management’s estimate of the amounts that will not be collected, based on the age of the receivable, payment history of the customer, general industry conditions, general financial condition of the customer and any financial or operational leverage the Company may have in a particular situation. Amounts are written-off when collection is deemed unlikely. Past due amounts are determined based on contractual terms. The Company generally does not charge interest on past due accounts. Cash and Cash Equivalents —The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. Short-term Investments— The Company considers all highly liquid investments with an original maturity greater than three months , but less than twelve months , to be short-term investments. Inventories —Inventories are stated at the lower of average cost (which approximates first-in, first-out) or market. An allowance for obsolescence is maintained to reduce the carrying value of any materials or parts that may become obsolete. Inventories are periodically monitored to ensure that the allowance for obsolescence covers any obsolete items. Seismic Equipment Lease Pool —Seismic equipment held for lease consists primarily of recording channels and peripheral equipment and is carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the equipment, which are five to seven years for channel boxes and two to 10 years for other peripheral equipment. As this equipment is subject to technological obsolescence and wear and tear, no salvage value is assigned to it. The Company continues to lease seismic equipment after it has been fully depreciated if it remains in acceptable condition and meets acceptable technical standards. This fully depreciated equipment remains in fixed assets on the Company’s books. The Company removes from its books the cost and accumulated depreciation of fully depreciated assets that are not expected to generate future revenues. Depreciation of equipment commences upon its initial deployment on a lease contract and continues uninterrupted from that point, regardless of whether the equipment is subsequently on a lease contract. Property and Equipment —Property and equipment is carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line method over the related estimated useful lives. The estimated useful lives of equipment range from three to seven years . Buildings are depreciated over 30 years and property improvements are amortized over 10 years . Leasehold improvements are amortized over the shorter of the realized estimated useful life or the life of the respective leases. No salvage value is assigned to property and equipment. Intangible Assets —Intangible assets are carried at cost, net of accumulated amortization. Amortization is computed on the straight-line method (for customer relationships, the straight-line method is not materially different from other methods that estimate run off of the underlying customer base) over the estimated life of the asset. Proprietary rights, developed technology and amortizable tradenames are amortized over a 10 to 15 -year period. Customer relationships are amortized over an eight -year period. Patents are amortized over an eight to nine -year period. Impairment —The Company reviews its long-lived assets, including its amortizable intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable . In reviewing for impairment, the carrying value of such assets is compared to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the carrying value of the long-lived asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived assets involves significant estimates on the part of management. The Company performs an impairment test on goodwill on an annual basis. The Company performs a qualitative review to determine if it is more likely than not that the fair value of our reporting units is greater their carrying value. If the Company is unable to conclude quantitatively that it is more likely than not that a reporting unit’s fair value exceeds its carrying value, then the Company performs a quantitative assessment of fair value of the reporting unit. The quantitative reviews involve significant estimates on the part of management. Product Warranties —Seamap provides its customers warranties against defects in materials and workmanship generally for a period of three months after delivery of the product. The Company maintains an accrual for potential warranty costs based on historical warranty claims. For the fiscal years ended January 31, 2018 , 2017 and 2016 , warranty expense was not material. Income Taxes —The Company accounts for income taxes under the liability method, whereby the Company recognizes deferred tax assets and liabilities which represent differences between the financial and income tax reporting basis of its assets and liabilities. Deferred tax assets and liabilities are determined based on temporary differences between income and expenses reported for financial reporting and tax reporting. The Company has assessed, using all available positive and negative evidence, the likelihood that the deferred tax assets will be recovered from future taxable income. The weight given to the potential effect of positive and negative evidence is commensurate with the extent to which it can be objectively verified. The preponderance of negative or positive evidence supports a conclusion regarding the need for a valuation allowance for some portion, or all, of the deferred tax asset. The more significant types of evidence considered include the following: • taxable income projections in future years; • our history of taxable income within a particular jurisdiction; • any history of the expiration of deferred tax assets without realization; • whether the carry forward period is so brief that it would limit realization of tax benefits; • other limitations on the utilization of tax benefits; • future sales and operating cost projections that will produce more than enough taxable income to realize the deferred tax asset based on existing sales prices and cost structures; • our earnings history exclusive of the loss that created the future deductible amount coupled with evidence indicating that the loss is an aberration rather than a continuing condition; and • tax planning strategies that will create additional taxable income. Use of Estimates —The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company’s management to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, the allowance for doubtful accounts, lease pool valuations, valuation allowance on deferred tax assets, the evaluation of uncertain tax positions, estimated depreciable lives of fixed assets and intangible assets, impairment of fixed assets and intangible assets, valuation of assets acquired and liabilities assumed in business combinations and the valuation of stock options. Future events and their effects cannot be perceived with certainty. Accordingly, these accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of the consolidated financial statements will change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes. Actual results could differ from these estimates. Substantial judgment is necessary in the determination of the appropriate levels for the Company’s allowance for doubtful accounts because of the extended payment terms the Company often offers to its customers and the limited financial wherewithal of certain of these customers. As a result, the Company’s allowance for doubtful accounts could change in the future, and such change could be material to the financial statements taken as a whole. The Company must also make substantial judgments regarding the valuation allowance on deferred tax assets and with respect to quantitative analysis prepared in conjunction with impairment analysis related to goodwill and other intangible assets. Fair Value of Financial Instruments — The Company’s financial instruments consist of accounts and contracts receivable, accounts payable and amounts outstanding under our credit facilities. Due to the maturities of these financial instruments and the variable rates under our credit agreements, the Company believes that their fair value approximates their carrying amounts. The Financial Accounting Standards Board (“FASB”) has issued guidance on the definition of fair value, the framework for using fair value to measure assets hierarchy, which prioritizes the inputs used to measure fair value. These tiers include: • Level 1: Defined as observable inputs such as quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. • Level 2: Defined as pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current and contractual prices for the underlying instruments, as well as other relevant economic measures. • Level 3: Defined as pricing inputs that are unobservable form objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value. The Company measures the fair values of goodwill, intangibles and other long-lived assets on a recurring basis if required by impairment tests applicable to these assets. The Company utilized Level 3 inputs to value goodwill, intangibles and other long-lived assets as of January 31, 2018 . See Notes 6 and 7 to our consolidated financial statements. Foreign Currency Translation —All balance sheet accounts of the Canadian, Australian, certain Singaporean, United Kingdom and Russian subsidiaries have been translated at the current exchange rate as of the end of the accounting period. Statements of operations items have been translated at average currency exchange rates. The resulting translation adjustment is recorded as a separate component of comprehensive income within shareholders’ equity. Stock-Based Compensation —Stock-based compensation expense is recorded based on the grant date fair value of share-based awards. Restricted stock awards are valued at the closing price on the date of grant. Determining the grant date fair value for options requires management to make estimates regarding the variables used in the calculation of the grant date fair value. Those variables are the future volatility of our common stock price, the length of time an optionee will hold their options until exercising them (the “expected term”), and the number of options that will be forfeited before they are exercised (the “forfeiture rate”). We utilize various mathematical models in calculating the variables. Share-based compensation expense could be different if we used different models to calculate the variables. Earnings Per Share —Net income (loss) per basic common share is computed using the weighted average number of common shares outstanding during the period. Net income (loss) per diluted common share is computed using the weighted average number of common shares and potential common shares outstanding during the period. Potential common shares result from the assumed exercise of outstanding common stock options having a dilutive effect using the treasury stock method, from unvested shares of restricted stock using the treasury stock method and from outstanding common stock warrants. For the fiscal years ended January 31, 2018 , 2017 and 2016 , the following table sets forth the number of potentially dilutive shares that may be issued pursuant to options, restricted stock and warrants outstanding used in the per share calculations. Years Ended January 31, 2018 2017 2016 (in thousands) Stock options 77 18 13 Restricted stock 32 44 46 Total dilutive shares 109 62 59 For the fiscal years ended January 31, 2018 , 2017 and 2016 , respectively, potentially dilutive common shares, underlying stock options and unvested restricted stock were anti-dilutive and were therefore not considered in calculating diluted loss per share for those periods. Reclassifications —Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications had no effect on the results of operations or comprehensive income.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In January 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, to simplify impairment testing of goodwill and other intangible assets by eliminating step two of the impairment test. ASU No. 2017-04 will be effective during the fiscal year ended January 31, 2021. The Company has adopted the provisions of ASU 2017-04 as of January 31, 2018. The adoption of ASU 2017-04 did not have a material effect on the Company's condensed consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, to require that amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Company has adopted the provisions of ASU No. 2016-18 as of February 1, 2017. The adoption of ASU No. 2016-18 did not have a material effect on the Company’s condensed consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230 ) : Classification of Certain Cash Receipts and Cash Payments , to address how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. ASU No. 2016-15 will be effective during the fiscal year ended January 31, 2019. The Company is evaluating the impact of ASU No. 2016-15 on its financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation -Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , to reduce complexity in accounting standards involving several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted this new standard as of February 1, 2017, utilizing the prospective transition method. As a result, the Company now recognizes all excess tax charges or benefits as income tax expense or benefit in the accompanying Consolidated Statements of Operations and in the accompanying Consolidated Statements of Cash Flows as operating activities. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , to provide guidance on recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements, specifically differentiating between different types of leases. ASU No. 2016-02 will be effective during the fiscal year ended January 31, 2020. The Company is evaluating the impact of ASU No. 2016-02 on its financial statements. In July 2015, the FASB issued ASU No. 2015-11, Inventory: (Topic 330) , to provide guidance on measurement of inventory. ASU 2015-11 requires that inventories utilizing the first-in, first-out (FIFO) method be measured at lower of cost or net realizable value. The Company has adopted the provisions of ASU 2015-11 as of February 1, 2017. The adoption of ASU 2015-11 did not have an impact on the Company’s consolidated financial statements as the Company’s inventory is determined using the average cost method. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. ASU 2014-09 was later amended by ASU No. 2016-10 Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , and ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients . ASU 2014-09, as amended, (the “Revenue Standard”) supersedes most industry specific guidance and intends to enhance comparability of revenue recognition practices across entities and industries by providing a principle-based, comprehensive framework for addressing revenue recognition issues. The Revenue Standard will be effective during the fiscal year ended January 31, 2019. The Company will adopt the Revenue Standard in the first quarter of fiscal 2019 and plans to use the modified retrospective method. The Company has analyzed a number of customer contracts and has determined that the Revenue Standard will be applicable to contracts performed by its Marine Technology Products segment, but not contracts performed by its Equipment Leasing segment. Based on the analysis the Company does not expect revenue recognition under the Revenue Standard to be materially different from the way contract revenue has been recognized under previous guidance. The Company is continuing to review its customer contracts in light of the Revenue Standard and evaluating the effect adoption will have on its financial statements, disclosures, and related internal controls.

The Tax Act contains (i) significant changes to corporate taxation, including reduction of the highest corporate tax rate from 35% to 21%, (ii) limitations on the deductibility of interest expense, business entertainment expenses, and executive compensation, and (iii) significant changes to U.S. international taxation, including a one time repatriation tax on undistributed earnings of foreign subsidiaries, the exemption from U.S. tax of certain foreign earnings upon their distribution to U.S. corporate shareholders, and the addition of a base erosion and anti-abuse tax. The Company's assessment of the effects of the Tax Act is not complete; therefore, provisional amounts under the Tax Act have been reported for fiscal year ended January 31, 2018 . As a result of the Tax Act reducing the corporate rate to 21%, effective January 1, 2018, the Company's effective federal income tax rate was reduced from 34% to 32.9% for the fiscal year ended January 31, 2018 . As a result of the reduction of the corporate tax rate to 21%, U.S. generally accepted accounting principles require the Company to re-value its deferred tax assets and liabilities as of the date of enactment, with resulting tax effects accounted for in the reporting period of enactment. The impact of revaluation was a decrease of approximately $7.0 million in value of the Company's U.S. deferred tax assets. The decrease in value of the U.S. deferred tax assets was directly offset by a corresponding reduction in the valuation allowance related to deferred tax assets. Therefore, no tax expense was recorded for the fiscal year ended January 31, 2018 as a result of the change in the corporate tax rate. The Company also recognized approximately $11.2 million of estimated U.S. taxable income due to the one-time repatriation of previously untaxed foreign earnings and profits imposed by the Tax Act. The repatriated foreign earnings were reported as a permanent difference and were entirely offset by current year U.S. net operating losses. As a result, the one-time repatriation of foreign earnings did not result in a tax liability for the Company. The Company has determined that, due to fundamental shifts in its business strategy to emphasize its Marine Technology Products business and the potential requirement for additional investment and working capital to achieve its objectives, the undistributed earnings of foreign subsidiaries as of January 31, 2018 , should no longer be deemed indefinitely reinvested outside of the United States. Furthermore, the Company has concluded that any deferred taxes with respect to the undistributed foreign earnings would be immaterial, particularly in light of the one-time repatriation of foreign earnings imposed by the Tax Act. Therefore, the Company has not recorded a deferred tax liability associated with the undistributed foreign earnings as of January 31, 2018 . Included in deferred tax assets is approximately $1.4 million related to stock based compensation, including non-qualified stock options. Recent prices for the Company’s common stock are below the exercise price for a significant number of these stock options. Should the price of the Company’s common stock remain below the exercise price of the options, these stock options will expire without exercise. In accordance with the provisions of ASC 718-740-10, a valuation allowance has not been computed based on the decline in stock price. As of January 31, 2018 , the Company has recorded valuation allowances of approximately $21.2 million related to deferred tax assets. These deferred tax assets relate primarily to net operating loss carryforwards in the United States and other jurisdictions. The valuation allowances were determined based on management’s judgment as to the likelihood that these deferred tax assets would be realized. The judgment was based on an evaluation of available evidence, both positive and negative. At January 31, 2018 , the Company had tax credit carry forwards of approximately $693,000 , which amounts can be carried forward through at least 2021 . As of January 31, 2018, 2017 and 2016 the company had no unrecognized tax benefits attributable to uncertain tax positions. Income tax expense for the fiscal year ended January 31, 2016 included approximately $92,000 of benefit related to reductions in uncertain tax positions. A reconciliation of the beginning and ending amounts of unrecognized tax benefits, excluding potential penalties and interest, is as follows: Years Ended January 31, 2018 2017 2016 (in thousands) Unrecognized tax benefits as of beginning of year $ — $ — $ 92 Increases as a result of tax positions taken in prior years — — — Increases as a result of tax positions taken in current year — — — Settlements — — (44 ) Lapse of statute of limitations — — (48 ) Unrecognized tax benefits as of end of year $ — $ — $ — The Company recognizes interest and penalties related to income tax matters as a component of income tax expense. Income tax expense for the fiscal year ended January 31, 2016 included approximately $145,000 of benefit related to a reduction in estimated penalties and interest for uncertain tax positions. Effective January 31, 2016 the Company has adopted the provisions of ASU 2015-17 on a prospective basis. Accordingly, all net deferred tax assets and liabilities are classified as long-term as of January 31, 2017 and January 31, 2018 in the accompanying Consolidated Balance Sheets. The company prospectively adopted the provisions of ASU 2016-09 beginning February 1, 2017. Accordingly, all excess tax benefits and deficiencies related to employee share-based payments are recognized as income tax benefits or expense in the accompanying Consolidated Statement of Operations and in the accompanying Consolidated Statement of Cash Flows as operating activities. For the fiscal year ended January 31, 2018 the excess tax deficiency for share-based payments recognized as tax expense was approximately $309,000 . The Company files U.S. federal income tax returns as well as separate returns for its foreign subsidiaries within their local jurisdictions.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Option Plans	Stock Option Plans At January 31, 2018 , the Company had stock-based compensation plans as described in more detail below. The total compensation expense related to stock-based awards granted under these plans during the fiscal years ended January 31, 2018 , 2017 and 2016 was approximately $903,000 , $737,000 and $1.3 million , respectively. The Company recognizes stock-based compensation costs net of a forfeiture rate for only those awards expected to vest over the requisite service period of the award. The Company estimates the forfeiture rate based on its historical experience regarding employee terminations and forfeitures. The fair value of each option award is estimated as of the date of grant using a Black-Scholes-Merton option pricing formula. Expected volatility is based on historical volatility of the Company’s stock over a preceding period commensurate with the expected term of the option. The expected term is based upon historical exercise patterns. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected dividend yield was not considered in the option pricing formula since the Company does not pay dividends and has not paid any dividends since its incorporation. The weighted average grant-date fair value of options granted during the fiscal years ended January 31, 2018 and 2016 were $2.02 and $1.64 , respectively. No options were granted during the fiscal year ended January 31, 2017 . The assumptions for the periods indicated are noted in the following table. Weighted average Black-Scholes-Merton fair value assumptions Years Ending January 31, 2018 2017 2016 Risk free interest rate 1.89 - 2.01% — 1.34 - 1.55% Expected life 4.87 - 6.87 yrs — 4.87 - 6.87 yrs Expected volatility 42 - 47% — 50 - 52% Expected dividend yield 0.0% — 0.0% Cash flows resulting from tax benefits attributable to tax deductions in excess of the compensation expense recognized for those options (excess tax benefits) are classified as financing out-flows and operating in-flows. The Company had no excess tax benefits during the fiscal years ended January 31, 2018 and 2017 . The Company had excess tax benefits of approximately $416,000 during the fiscal year ended January 31, 2016 . The Company has share-based awards outstanding under five different plans: the 1994 Stock Option Plan (“1994 Plan”), the 1998 Amended and Restated Stock Awards Plan (“1998 Plan”), the 2000 Stock Option Plan (“2000 Plan”), the Mitcham Industries, Inc. Stock Awards Plan (“2006 Plan”) and the 1994 Non-Employee Director Plan (“Director Plan”), (collectively, the “Plans”). Stock options granted and outstanding under each of the plans generally vest evenly over three years (except for the Director Plan, under which options generally vest after one year ) and have a 10 -year contractual term. The exercise price of a stock option generally is equal to the fair market value of the Company’s common stock on the option grant date. All Plans except for the 2006 Plan have been closed for future grants. All shares available but not granted under the 1998 Plan and the 2000 Plan as of the date of the approval of the 2006 Plan were transferred to the 2006 Plan. As of January 31, 2018 , there were approximately 218,000 shares available for grant under the 2006 Plan. The 2006 Plan provides for awards of nonqualified stock options, incentive stock options, restricted stock awards, restricted stock units and phantom stock. New shares are issued for restricted stock and upon the exercise of options. Stock Based Compensation Activity The following table presents a summary of the Company’s stock option activity for the fiscal year ended January 31, 2018 : Number of Shares (in thousands) Weighted Average Exercise Price Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding, January 31, 2017 1,781 $ 9.27 5.90 $ 778 Granted 549 4.66 Exercised — — Forfeited (94 ) 11.24 Expired (64 ) 17.70 Outstanding, January 31, 2018 2,172 $ 7.75 6.16 $ 320 Exercisable at January 31, 2018 1,400 $ 9.51 4.84 $ 214 Vested and expected to vest at January 31, 2018 2,149 $ 7.53 6.01 $ 318 The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the fourth quarter of fiscal 2018 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on January 31, 2018 . This amount changes based upon the market value of the Company’s common stock. No options were exercised during the fiscal years ended January 31, 2018 , 2017 , and 2016 . The fair value of options that vested during the fiscal years ended January 31, 2018 , 2017 and 2016 was approximately $0.5 million , $1.0 million and $1.5 million , respectively. For the fiscal year ended January 31, 2018 , approximately 245,000 options vested. As of January 31, 2018 , there was approximately $578,000 of total unrecognized compensation expense related to unvested stock options granted under the Company’s share-based compensation plans. That expense is expected to be recognized over a weighted average period of 0.9 years . Restricted stock as of January 31, 2018 and changes during the fiscal year ended January 31, 2018 were as follows: Year Ended January 31, 2018 Number of Shares (in thousands) Weighted Average Grant Date Fair Value Unvested, beginning of period 12 $ 11.89 Granted — — Vested (10 ) 13.03 Canceled — — Unvested, end of period 2 $ 9.97 As of January 31, 2018 , there was approximately $2,000 of unrecognized stock-based compensation expense related to unvested restricted stock awards. That expense is expected to be recognized over a weighted average period of 0.6 years .

Leases [Abstract]
Leases	Leases The Company leases seismic equipment to customers under operating leases with non-cancelable terms of one year or less. These leases are generally renewable on a month-to-month basis. All taxes (other than income taxes) and assessments are the contractual responsibility of the lessee. To the extent that foreign taxes are not paid by the lessee, the relevant foreign taxing authorities might seek to collect such taxes from the Company. Under the terms of its lease agreements, any amounts paid by the Company to such foreign taxing authorities may be billed and collected from the lessee. If the Company is unable to collect the foreign taxes it paid on behalf of its lessees, the Company may have foreign tax credits in the amounts paid, which could be applied against its U.S. income tax liability subject to certain limitations. The Company is not aware of any foreign tax obligations as of January 31, 2018 and 2017 that are not reflected in the accompanying consolidated financial statements. The Company leases seismic equipment, as well as other equipment from others under operating leases. Lease expense incurred by the Company in connection with such leases amounted to approximately $774,000 , $552,000 and $831,000 for the fiscal years ended January 31, 2018 , 2017 and 2016 , respectively. The Company leases its office and warehouse facilities in Canada, Australia, Singapore, United Kingdom, Hungary, Colombia and Russia under operating leases. Office rental expense for the fiscal years ended January 31, 2018 , 2017 and 2016 was approximately $1.2 million , $1.2 million and $1.2 million , respectively. Aggregate minimum lease payments for non-cancelable operating leases are as follows (in thousands): For fiscal years ending January 31: 2019 $ 1,140 2020 688 2021 316 2022 15 2023 6

Risks and Uncertainties [Abstract]
Concentrations	Concentrations Credit Risk —As of January 31, 2018 and 2017 , amounts due from customers that exceeded 10% of consolidated accounts receivable amounted to an aggregate of approximately $5.8 million from three customers and $5.1 million from three customers, respectively. The Company maintains deposits and certificates of deposit with banks which may exceed the Federal Deposit Insurance Corporation (“FDIC”) insured limit and money market accounts which are not FDIC insured. In addition, deposits aggregating approximately $3.9 million at January 31, 2018 are held in foreign banks. Management believes the risk of loss in connection with these accounts is minimal. Industry Concentration —The majority of the Company’s revenues are derived from seismic equipment leased and sold to companies providing seismic acquisition services. The seismic industry has historically been subject to cyclical activity and is dependent, in large part, on the expected future prices of oil and natural gas. Should the industry experience a decline in the price of oil and natural gas, the Company could be subject to significantly greater credit risk and declining demand for its products and services. Supplier Concentration —The Company purchases the majority of its seismic equipment for its lease pool from a small number of suppliers, each being an industry leader for its product. The Company believes that two of its suppliers manufacture most of the land-based seismic systems and equipment in use. The Company has satisfactory relationships with its suppliers. However, should those relationships deteriorate, the Company may have difficulty in obtaining new technology requested by its customers and maintaining the existing equipment in accordance with manufacturers’ specifications.

Subsequent Events [Abstract]
Subsequent Event	Subsequent Event In February 2018 the Company completed the acquisition of intellectual property and certain other assets from Hydroscience Technologies, Inc. and Solid Seismic LLC (collectively “Hydroscience”). Hydroscience designed, manufactured and sold marine sensors and solid streamer technology primarily for the hydrographic and seismic industries. In April 2017 Hydroscience filed for bankruptcy protection. Mitcham acquired the assets pursuant to an Asset Purchase Agreement and Sale Order that were approved by the bankruptcy court on January 31, 2018. Under these agreements, Mitcham acquired certain specified intangible and tangible assets free and clear of all prior claims and encumbrances for consideration of $3.0 million in cash and an agreement to forego accounts receivable balances due from Hydroscience with a carrying value of approximately $1.2 million . Mitcham assumed no contracts or prior warranty obligations. In connection with the closing of the acquisition, Mitcham issued 152,290 shares of Preferred Stock to Mitsubishi Heavy Industries, Ltd ("MHI") for proceeds of $3.5 million pursuant to a securities purchase agreement between Mitcham and MHI. In addition, MHI agreed to purchase an additional 21,756 shares of Preferred Stock for $500,000 upon the satisfaction of certain conditions specified in the securities purchase agreement.

Organization and Summary of S30

Organization and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jan. 31, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization —Mitcham Industries, Inc., a Texas corporation (the “Company”), was incorporated in 1987. The Company, through its wholly owned subsidiary, Seamap International Holdings Pte, Ltd. (“Seamap”), and its wholly owned subsidiary, Klein Marine Systems, Inc. (“Klein”), designs, manufactures and sells a broad range of proprietary products for the seismic, hydrographic and offshore industries with product sales and support facilities based in New Hampshire, Singapore and the United Kingdom. The Company, through its wholly owned Australian subsidiary, Seismic Asia Pacific Pty Ltd. (“SAP”), provides seismic, oceanographic and hydrographic leasing and sales worldwide, primarily in Southeast Asia and Australia. The Company, through its wholly owned Canadian subsidiary, Mitcham Canada, ULC (“MCL”), its wholly owned Russian subsidiary, Mitcham Seismic Eurasia LLC (“MSE”), its wholly owned Hungarian subsidiary, Mitcham Europe Ltd. (“MEL”), its wholly owned Singaporean subsidiary, Mitcham Marine Leasing Pte. Ltd. (“MML”), and its branch operations in Colombia, provides full-service equipment leasing, sales and service to the seismic industry worldwide. All intercompany transactions and balances have been eliminated in consolidation.
Revenue Recognition of Leasing Arrangements	Revenue Recognition of Leasing Arrangements —The Company leases various types of seismic equipment to seismic data acquisition companies. All leases at January 31, 2018 , 2017 and 2016 are for one year or less. Lease revenue is recognized ratably over the term of the lease. The Company does not enter into leases with embedded maintenance obligations. The standard lease provides that the lessee is responsible for maintenance and repairs to the equipment, excluding normal wear and tear. The Company occasionally provides technical advice to its customers without additional compensation as part of its customer service practices. Repairs or maintenance performed by the Company is charged to the lessee, generally on a time and materials basis. Repair and maintenance revenue is recognized as incurred.
Revenue Recognition of Equipment Sales	Revenue Recognition of Equipment Sales —Revenues and cost of sales from the sale of equipment are recognized upon acceptance of terms and when delivery has occurred, unless there is a question as to collectability. In cases where the equipment sold is manufactured by others, the Company reports revenues at gross amounts billed to customers because the Company: (a) is the obligor in the sales arrangement; (b) has full latitude in pricing the product for sale; (c) has general inventory risk should there be a problem with the equipment being sold to the customer or if the customer does not complete payment for the items purchased; (d) has discretion in supplier selection if the equipment ordered is not unique to one manufacturer; and (e) assumes credit risk for the equipment sold to its customers.
Revenue Recognition of Long-term Projects	Revenue Recognition of Long-term Projects —From time to time, SAP and Klein enter into contracts whereby they assemble and sell certain marine equipment, primarily to governmental entities. Performance under these contracts generally occurs over a period of several months. Revenue and costs related to these contracts are accounted for under the percentage of completion method, based on estimated physical completion.
Revenue Recognition of Service Agreements	Revenue Recognition of Service Agreements —Seamap provides on-going support services pursuant to contracts that generally have a term of 12 months . The Company recognizes revenue from these contracts over the term of the contract. In some cases, the Company will provide support services on a time and material basis. Revenue from these arrangements is recognized as the services are provided. For certain new systems that Seamap sells, the Company provides support services for up to 12 months at no additional charge. Any amounts attributable to these support obligations are immaterial. Revenues from service contracts for each of the three months ended January 31, 2018 were not material. Due to immateriality, service revenues are not presented separately in the financial statements.
Contracts Receivable	Contracts Receivable —In connection with the sale of seismic equipment, the Company will, from time to time, accept a contract receivable as partial consideration. These contracts bear interest at a market rate, generally have terms of less than two years and are collateralized by a security interest in the equipment sold. Interest income on contracts receivable is recognized as earned, unless there is a question as to collectability in which case it is recognized when received.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts —Trade receivables are uncollateralized customer obligations due under normal trade terms. The carrying amount of trade receivables and contracts receivable is reduced by a valuation allowance that reflects management’s estimate of the amounts that will not be collected, based on the age of the receivable, payment history of the customer, general industry conditions, general financial condition of the customer and any financial or operational leverage the Company may have in a particular situation. Amounts are written-off when collection is deemed unlikely. Past due amounts are determined based on contractual terms. The Company generally does not charge interest on past due accounts.
Cash and Cash Equivalents	Cash and Cash Equivalents —The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents.
Short-term Investments	Short-term Investments— The Company considers all highly liquid investments with an original maturity greater than three months , but less than twelve months , to be short-term investments.
Inventories	Inventories —Inventories are stated at the lower of average cost (which approximates first-in, first-out) or market. An allowance for obsolescence is maintained to reduce the carrying value of any materials or parts that may become obsolete. Inventories are periodically monitored to ensure that the allowance for obsolescence covers any obsolete items.
Seismic Equipment Lease Pool	Seismic Equipment Lease Pool —Seismic equipment held for lease consists primarily of recording channels and peripheral equipment and is carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line method over the estimated useful lives of the equipment, which are five to seven years for channel boxes and two to 10 years for other peripheral equipment. As this equipment is subject to technological obsolescence and wear and tear, no salvage value is assigned to it. The Company continues to lease seismic equipment after it has been fully depreciated if it remains in acceptable condition and meets acceptable technical standards. This fully depreciated equipment remains in fixed assets on the Company’s books. The Company removes from its books the cost and accumulated depreciation of fully depreciated assets that are not expected to generate future revenues. Depreciation of equipment commences upon its initial deployment on a lease contract and continues uninterrupted from that point, regardless of whether the equipment is subsequently on a lease contract.
Property and Equipment	Property and Equipment —Property and equipment is carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line method over the related estimated useful lives. The estimated useful lives of equipment range from three to seven years . Buildings are depreciated over 30 years and property improvements are amortized over 10 years . Leasehold improvements are amortized over the shorter of the realized estimated useful life or the life of the respective leases. No salvage value is assigned to property and equipment.
Intangible Assets	Intangible Assets —Intangible assets are carried at cost, net of accumulated amortization. Amortization is computed on the straight-line method (for customer relationships, the straight-line method is not materially different from other methods that estimate run off of the underlying customer base) over the estimated life of the asset. Proprietary rights, developed technology and amortizable tradenames are amortized over a 10 to 15 -year period. Customer relationships are amortized over an eight -year period. Patents are amortized over an eight to nine -year period.
Impairment	Impairment —The Company reviews its long-lived assets, including its amortizable intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable . In reviewing for impairment, the carrying value of such assets is compared to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the carrying value of the long-lived asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived assets involves significant estimates on the part of management. The Company performs an impairment test on goodwill on an annual basis. The Company performs a qualitative review to determine if it is more likely than not that the fair value of our reporting units is greater their carrying value. If the Company is unable to conclude quantitatively that it is more likely than not that a reporting unit’s fair value exceeds its carrying value, then the Company performs a quantitative assessment of fair value of the reporting unit. The quantitative reviews involve significant estimates on the part of management.
Product Warranties	Product Warranties —Seamap provides its customers warranties against defects in materials and workmanship generally for a period of three months after delivery of the product. The Company maintains an accrual for potential warranty costs based on historical warranty claims.
Income Taxes	Income Taxes —The Company accounts for income taxes under the liability method, whereby the Company recognizes deferred tax assets and liabilities which represent differences between the financial and income tax reporting basis of its assets and liabilities. Deferred tax assets and liabilities are determined based on temporary differences between income and expenses reported for financial reporting and tax reporting. The Company has assessed, using all available positive and negative evidence, the likelihood that the deferred tax assets will be recovered from future taxable income. The weight given to the potential effect of positive and negative evidence is commensurate with the extent to which it can be objectively verified. The preponderance of negative or positive evidence supports a conclusion regarding the need for a valuation allowance for some portion, or all, of the deferred tax asset. The more significant types of evidence considered include the following: • taxable income projections in future years; • our history of taxable income within a particular jurisdiction; • any history of the expiration of deferred tax assets without realization; • whether the carry forward period is so brief that it would limit realization of tax benefits; • other limitations on the utilization of tax benefits; • future sales and operating cost projections that will produce more than enough taxable income to realize the deferred tax asset based on existing sales prices and cost structures; • our earnings history exclusive of the loss that created the future deductible amount coupled with evidence indicating that the loss is an aberration rather than a continuing condition; and • tax planning strategies that will create additional taxable income.
Use of Estimates	Use of Estimates —The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company’s management to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, the allowance for doubtful accounts, lease pool valuations, valuation allowance on deferred tax assets, the evaluation of uncertain tax positions, estimated depreciable lives of fixed assets and intangible assets, impairment of fixed assets and intangible assets, valuation of assets acquired and liabilities assumed in business combinations and the valuation of stock options. Future events and their effects cannot be perceived with certainty. Accordingly, these accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of the consolidated financial statements will change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes. Actual results could differ from these estimates.
Fair Value of Financial Instruments	Fair Value of Financial Instruments — The Company’s financial instruments consist of accounts and contracts receivable, accounts payable and amounts outstanding under our credit facilities. Due to the maturities of these financial instruments and the variable rates under our credit agreements, the Company believes that their fair value approximates their carrying amounts. The Financial Accounting Standards Board (“FASB”) has issued guidance on the definition of fair value, the framework for using fair value to measure assets hierarchy, which prioritizes the inputs used to measure fair value. These tiers include: • Level 1: Defined as observable inputs such as quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. • Level 2: Defined as pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current and contractual prices for the underlying instruments, as well as other relevant economic measures. • Level 3: Defined as pricing inputs that are unobservable form objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value. The Company measures the fair values of goodwill, intangibles and other long-lived assets on a recurring basis if required by impairment tests applicable to these assets. The Company utilized Level 3 inputs to value goodwill, intangibles and other long-lived assets as of January 31, 2018 .
Foreign Currency Translation	Foreign Currency Translation —All balance sheet accounts of the Canadian, Australian, certain Singaporean, United Kingdom and Russian subsidiaries have been translated at the current exchange rate as of the end of the accounting period. Statements of operations items have been translated at average currency exchange rates. The resulting translation adjustment is recorded as a separate component of comprehensive income within shareholders’ equity.
Stock-Based Compensation	Stock-Based Compensation —Stock-based compensation expense is recorded based on the grant date fair value of share-based awards. Restricted stock awards are valued at the closing price on the date of grant. Determining the grant date fair value for options requires management to make estimates regarding the variables used in the calculation of the grant date fair value. Those variables are the future volatility of our common stock price, the length of time an optionee will hold their options until exercising them (the “expected term”), and the number of options that will be forfeited before they are exercised (the “forfeiture rate”). We utilize various mathematical models in calculating the variables. Share-based compensation expense could be different if we used different models to calculate the variables.
Earnings Per Share	Earnings Per Share —Net income (loss) per basic common share is computed using the weighted average number of common shares outstanding during the period. Net income (loss) per diluted common share is computed using the weighted average number of common shares and potential common shares outstanding during the period. Potential common shares result from the assumed exercise of outstanding common stock options having a dilutive effect using the treasury stock method, from unvested shares of restricted stock using the treasury stock method and from outstanding common stock warrants.
Reclassifications	Reclassifications —Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications had no effect on the results of operations or comprehensive income.
New Accounting Pronouncements	New Accounting Pronouncements In January 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, to simplify impairment testing of goodwill and other intangible assets by eliminating step two of the impairment test. ASU No. 2017-04 will be effective during the fiscal year ended January 31, 2021. The Company has adopted the provisions of ASU 2017-04 as of January 31, 2018. The adoption of ASU 2017-04 did not have a material effect on the Company's condensed consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, to require that amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Company has adopted the provisions of ASU No. 2016-18 as of February 1, 2017. The adoption of ASU No. 2016-18 did not have a material effect on the Company’s condensed consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230 ) : Classification of Certain Cash Receipts and Cash Payments , to address how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. ASU No. 2016-15 will be effective during the fiscal year ended January 31, 2019. The Company is evaluating the impact of ASU No. 2016-15 on its financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation -Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , to reduce complexity in accounting standards involving several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted this new standard as of February 1, 2017, utilizing the prospective transition method. As a result, the Company now recognizes all excess tax charges or benefits as income tax expense or benefit in the accompanying Consolidated Statements of Operations and in the accompanying Consolidated Statements of Cash Flows as operating activities. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , to provide guidance on recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements, specifically differentiating between different types of leases. ASU No. 2016-02 will be effective during the fiscal year ended January 31, 2020. The Company is evaluating the impact of ASU No. 2016-02 on its financial statements. In July 2015, the FASB issued ASU No. 2015-11, Inventory: (Topic 330) , to provide guidance on measurement of inventory. ASU 2015-11 requires that inventories utilizing the first-in, first-out (FIFO) method be measured at lower of cost or net realizable value. The Company has adopted the provisions of ASU 2015-11 as of February 1, 2017. The adoption of ASU 2015-11 did not have an impact on the Company’s consolidated financial statements as the Company’s inventory is determined using the average cost method. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. ASU 2014-09 was later amended by ASU No. 2016-10 Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , and ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients . ASU 2014-09, as amended, (the “Revenue Standard”) supersedes most industry specific guidance and intends to enhance comparability of revenue recognition practices across entities and industries by providing a principle-based, comprehensive framework for addressing revenue recognition issues. The Revenue Standard will be effective during the fiscal year ended January 31, 2019. The Company will adopt the Revenue Standard in the first quarter of fiscal 2019 and plans to use the modified retrospective method. The Company has analyzed a number of customer contracts and has determined that the Revenue Standard will be applicable to contracts performed by its Marine Technology Products segment, but not contracts performed by its Equipment Leasing segment. Based on the analysis the Company does not expect revenue recognition under the Revenue Standard to be materially different from the way contract revenue has been recognized under previous guidance. The Company is continuing to review its customer contracts in light of the Revenue Standard and evaluating the effect adoption will have on its financial statements, disclosures, and related internal controls.
