Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	(1) Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements include the accounts of Superior Energy Services, Inc. and subsidiaries (the Company). All significant intercompany accounts and transactions are eliminated in consolidation. Certain previously reported amounts have been rec lassified to conform to the 2017 presentation. Business The Company provides a wide variety of services and products to the energy industry. The Company serves major, national and independent oil and natural gas companies around the world and offers products and services with respect to the various phases of a well’s economic life cycle. The Company reports its operating results in four business segments: Drilling Products and Services; Onshore Completion and Workover Services; Production Services; and Technical Solutions. Given the Company’s long-term strategy of expanding geographically, the Company also provides supplemental segment revenue information in three geographic areas: U.S. land; Gulf of Mexico; and International. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Major Customers and Concentration of Credit Risk The majority of the Company’s business is conducted with major and independent oil and gas companies. The Company evaluates the financial strength of its customers and provides allowances for probable credit losses when deemed necessary. The market for the Company’s services and products is the oil and gas industry in the U.S. land and Gulf of Mexico areas and select international market areas. Oil and gas companies make capital expenditures on exploration, development and production operations. The level of these expenditures historically has been characterized by significant volatility. The Company derives a large amount of revenue from a small number of major and independent oil and gas companies. Anadarko accounted for approximately 13% and 11% of the Company’s revenues in 2017 and 2016, respectively, primarily within the Onshore Completion and Workover Services segment. There were no customers that exceeded 10% of our total revenues in 2015 . The Company’s assets that are potentially exposed to concentrations of credit risk consist primarily of cash , cash equivalents and trade receivables. The financial institutions in which the Company transacts business are large, investment grade financial institutions which are “well capitalized” under applicable regulatory capital adequacy guidelines , thereby minimizing it s exposure to credit risks for deposits in excess of federally insured amounts and for failure to perform as the counterparty on interest rate swap agreements. The Company periodically evaluates the creditworthiness of financial institutions that may serve as a counterparty to its derivative instruments . Cash Equivalents The Company considers all short-term investments with a maturity of 90 days or less when purchased to be cash equivalents. Accounts Receivable and Allowances Trade accounts receivable are recorded at the invoiced amount or the earned amount but not yet invoiced and do not bear interest. The Company maintains allowances for estimated uncollectible receivables, including bad debts and other items. The allowance for doubtful accounts is based on the Company’s best estimate of probable uncollectible amounts in existing accounts receivable. The Company determines the allowance based on historical write-off experience and specific identification. Inventory Inventories are stated at the lower of cost or net realizable value. The Company applies net realizable value and obsolescence to the gross value of the inventory. Cost is determined using the first-in, first-out or weighted-average cost methods for finis hed goods and work-in-process. Supplies and consumables consist principally of products used in the Company’s services provided to its customers. The components of inventory balances are as follows (in thousands): December 31, 2017 December 31, 2016 Finished goods $ 61,764 $ 49,888 Raw materials 13,727 17,948 Work-in-process 6,174 5,214 Supplies and consumables 24,923 30,029 Total $ 106,588 $ 103,079 Property, Plant and Equipment Property, plant and equipment are stated at cost, except for assets for which reduction in value is recorded during the period and assets acquired using purchase accounting, which are recorded at fair value as of the date of acquisition. With the exception of certain marine assets and oil and natural gas property, depreciation is computed using the straight line method over the estimated useful lives of the related assets as follows: Buildings and improvements 5 to 40 years Marine vessels and equipment 5 to 25 years Machinery and equipment 2 to 25 years Automobiles, trucks, tractors and trailers 3 to 10 years Furniture and fixtures 2 to 10 years The Company follows the successful efforts method of accounting for its investment in oil and natural gas property. Under the successful efforts method, the costs of successful exploratory wells and leases containing productive reserves are capitalized. Costs incurred to drill and equip developmental wells, including unsuccessful wells, are capitalized. Other costs such as geological and geophysical costs and the drilling costs of unsuccessful exploratory wells are expensed. Leasehold and well costs are depleted on a units-of-production basis based on the estimated remaining equivalent oil and gas reserves. Reduction in Value of Long-Lived Assets Long-lived assets, such as property, plant and equipment and purchased intangibles subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is assessed by a comparison of the carrying amount of such assets to their fair value calculated, in part, by the estimated undiscounted future cash flows expected to be generated by the assets. Cash flow estimates are based upon, among other things, historical results adjusted to reflect the best estimate of future market rates, utilization levels, and operating performance. Estimates of cash flows may differ from actual cash flows due to, among other things, changes in economic conditions or changes in an asset’s operating performance. The Company’s assets are grouped by subsidiary or division for the impairment testing, which represent the lowest level of identifiable cash flows. If the asset grouping’s fair value is less than the carrying amount of those items, impairment losses are recorded in the amount by which the carrying amount of such assets exceeds the fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value less estimated costs to sell. The net carrying value of assets not fully recoverable is reduced to fair value. The estimate of fair value represents the Company’s best estimate based on industry trends and reference to market transactions and is subject to variability. The oil and gas industry is cyclical and estimates of the period over which future cash flows will be generated, as well as the predictability of these cash flows, can have a significant impact on the carrying values of these assets and, in periods of prolonged down cycles, may result in impairment charges. See note 3 for a discussion of the reduction in value of long-lived assets recorded during 2017, 2016 and 2015. Goodwill The following table summarizes the activity for the Company’s goodwill (in thousands): Onshore Drilling Completion Products and Workover Production and Services Services Services Total Balance, December 31, 2015 $ 141,282 $ 723,550 $ 275,269 $ 1,140,101 Reduction in value of assets - (140,000) (190,500) (330,500) Foreign currency translation adjustment (5,321) - (363) (5,684) Balance, December 31, 2016 135,961 583,550 84,406 803,917 Foreign currency translation adjustment 2,532 - 1,411 3,943 Balance, December 31, 2017 $ 138,493 $ 583,550 $ 85,817 $ 807,860 During the first quarter of 2017, the Company adopted the Financial Accounting Standards Board (FASB) update (ASU) 2017-04, Intangibles- Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in the ASU eliminate Step 2 from the goodwill impairment test. The annual or interim goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The Company performs the goodwill impairment test on an annual basis as of October 1 st or on an interim basis if events or circumstances indicate that the fair value of the asset has decre ased below its carrying value. In order to estimate the fair value of the reporting units (which is consistent with the reported business segments), the Company used a weighting of the discounted cash flow method and the public company guideline method of determining fair value of each reporting unit. The Company weighted the discounted cash flow method 80 % and the public company guideline method 20 % due to differences between the Company’s reporting units and the peer companies’ size, profitabilit y and diversity of operations. These fair value estimates were then compared to the carrying value of the reporting units. If the fair value of the reporting unit exceeds the carrying amount, no impairment loss is recognized. If the estimated fair value of the reporting unit is below the carrying value, then an impairment is recorded, which represents the amount by which a reporting unit’s carrying value exceeds its fair value. The Company uses all available information to estimate fair value of the reporting units, including discounted cash flows. A significant amount of judgment was involved in performing these evaluations since the results are based on estimated future events. See note 3 for a discussion of the reduction in value of goodwill recorded during 2016 and 2015. At December 31, 2017 and 2016 , the Company’s accumulated reduction in value of goodwill was $1,748.2 million . Notes Receivable The Company’s wholly owned subsidiary, Wild Well, has decommissioning obligations related to its ownership of the Bullwinkle platform. Notes receivable consist of a commitment from the seller of the platform towards its eventual abandonment. Pursuant to an agreement with the seller, the Company will invoice the seller an agreed upon amount at the completion of certain decommissioning activities. The gross amount of this obligation totaled $ 115.0 million and is recorded at present value using an effective interest rate of 6.58 %. The related discount is amortized to interest income based on the expected timing of the platform’s removal. The Company recorded interest income related to notes receivable of $ 3.6 million, $ 3.6 million and $1.7 million during 2017 , 2016 and 201 5 , respectively. Intangible and Other Long-Term Assets Intangible assets consist of the following (in thousands): December 31, 2017 2016 Estimated Gross Accumulated Net Gross Accumulated Net Useful Lives Amount Amortization Balance Amount Amortization Balance Customer relationships 17 years $ 165,036 $ (62,930) $ 102,106 $ 164,603 $ (52,747) $ 111,856 Tradenames 10 years 30,732 (17,188) 13,544 30,519 (14,123) 16,396 Non-compete agreements 3 years 4,299 (3,241) 1,058 2,790 (2,718) 72 Total $ 200,067 $ (83,359) $ 116,708 $ 197,912 $ (69,588) $ 128,324 Amortization expense was $ 12.7 million, $16.2 million and $23.0 million during 2017 , 2016 and 2015 , respectively. Based on the carrying values of intang ible assets at December 31, 2017 , amortization expen se for the next five years (2018 through 2022 ) is estimated to b e $ 12.6 million per year. Intangible and other long-term assets, net included $20.5 million and $58.5 million of escrowed cash at December 31, 2017 and 2016 , respectively, primarily related to the future decommissioning obligations of the Bullwinkle platform. During 2017, $30.6 million was released from the escrow account. Decommissioning Liabilities The Company’s decommissioning liabilities associated with the Bullwinkle platform and its related assets consist of costs related to the plugging of wells, the removal of the related platform and equipment, and site restoration. The Company reviews the adequacy of its decommissioning liabilities whenever indicators suggest that the estimated cash flows needed to satisfy the liability have changed materially. The following table summarizes the activity for the Company’s decommissioning liabilities (in thousands): December 31, 2017 2016 Decommissioning liabilities, December 31, 2016 and 2015, respectively $ 123,677 $ 117,942 Revisions in estimated timing and cash flows - (2,132) Accretion 6,837 6,959 Liability acquisitions and dispositions (117) 908 Total decommissioning liabilities, December 31, 2017 and 2016, respectively $ 130,397 $ 123,677 Revenue Recognition Products and services are generally sold based upon purchase orders or contracts with customers that include fixed or determinable prices. Revenue is recognized when services or equipment are provided and collectability is reasonably assured. The Company’s drilling products and services are billed on a day rate basis, and revenue from the sale of equipment is recognized when the title to the equipment has been transferred. Reimbursements from customers for the cost of drilling products and services that are damaged or lost down-hole are reflected as revenue at the time of the incident. The Company recognizes oil and gas revenue from its interests in producing wells as oil and natural gas is sold. Taxes collected from customers and remitted to governmental authorities are reported on a net basis in the Company’s financial statements. Income Taxes The Company accounts for income taxes and the related accounts under the asset and liability method. Deferred income taxes reflect the impact of temporary differences between amounts of assets and liabilities for financial reporting purposes and such amounts as measured by tax laws and rates that are in effect when the temporary differences are expected to reverse. The effect of a change in tax rates on the deferred income taxes is recognized in income in the period in which the change occurs. A valuation allowance is recorded when management believes it is more likely than not that at least some portion of any deferred tax asset will not be realized. It is the Company’s policy to recognize interest and applicable penalties related to uncertain tax positions in income tax expense. Earnings per Share Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed in the same manner as basic earnings per share except that the denominator is increased to include the number of additional shares of common stock that could have been outstanding assuming the exercise of stock options and conversion of restricted stock units. During 2017, 2016 and 2015, the Company incurred losses from continuing operations; therefore the impact of any incremental shares would be anti-dilutive. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or the price paid to transfer a liability in an orderly transaction between market participants at the measurement date. Inputs used in determining fair value are characterized according to a hierarchy that prioritizes those inputs based on the degree to which they are observable. The three input levels of the fair value hierarchy are as follows: Level 1 : Unadjusted quoted prices in active markets for identical assets and liabilities; Level 2 : Observable inputs other than those included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical assets or liabilities in inactive markets or model-derived valuations or other inputs that can be corroborated by observable market data; and Level 3 : Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability. Financial Instruments The fair value of the Company’s financial instruments of cash equivalents, accounts receivable, accounts payable, accrued expenses and borrowings under its credit facility approximates their carrying amounts due to their short maturity or market interest rates. The fair value of the Company’s debt was $ 1,347.0 million and $ 1,307.6 million at December 31, 2017 and 2016 , respectively, and was categorized as Level 1 in the fair value hierarchy. The fair value of these debt instruments is determined by reference to the market value of the instrument as quoted in an over-the-counter market. Foreign Currency Results of operations for foreign subsidiaries with functional currencies other than the U.S. dollar are translated using average exchange rates during the period. Assets and liabilities of these foreign subsidiaries are translated using the exchange rates in effect at the balance sheet dates, and the resulting translation adjustments are reported as accumulated other comprehensive loss in the Company’s stockholders’ equity. For international subsidiaries where the functional currency is the U.S. dollar, financial statements are remeasured into U.S. dollars using the historical exchange rate for most of the long-term assets and liabilities and the balance sheet date exchange rate for most of the current assets and liabilities. An average exchange rate is used for each period for revenues and expenses. These transaction gains and losses, as well as any other transactions in a currency other than the functional currency, are included in other income (expense) in the consolidated statements of operations in the period in which the currency exc hange rates change. During 2017 , 2016 and 2015 , the Company recorded foreign currency gains/(losses) of $(2.2) m illion, $23.5 million and $(9.6) million , respectively. Stock-Based Compensation The Company records compensation costs relating to share-based payment transactions and includes such costs in general and administrative expenses in the consolidated statements of operations. The cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award). Derivative Instruments and Hedging Activities The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. Interest rate swap agreements that are effective at hedging the fair value of fixed-rate debt agreements are designated and accounted for as fair value hedges. The Company also assesses, both at inception of the hedging relationship and on an ongoing basis, whether the derivatives used in hedging relationships are highly effective in offsetting changes in fair value. Self-Insurance Reserves The Company is self-insured, through deductibles and retentions, up to certain levels for losses under its insurance programs. The Company accrues for these liabilities based on estimates of the ultimate cost of claims incurred as of the balance sheet date. The Company regularly reviews the estimates of reported and unreported claims and provides for losses through reserves. The Company obtains actuarial reviews to evaluate the reasonableness of internal estimates for losses related to workers’ compensation, auto liability and group medical on an annual basis. New Accounting Pronouncements Standards adopted In January 2017, the Financial Accounting Standards Board (FASB) issued accounting standards update (ASU) 2017-04, Intangibles- Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments eliminate Step 2 from the goodwill impairment test. The annual or interim goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The amendments should be applied on a prospective basis. The new standard is effective for the Company on January 1, 2020. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company adopted the accounting guidance as of January 1, 2017. The newly adopted accounting principle is preferable because it reduces the cost and complexity of evaluating goodwill for impairment. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which relates to the accounting for employee share-based payments. The guidance in this update addresses several aspects of the accounting for share-based payments, including income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The Company adopted the accounting guidance as of January 1, 2017. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330) – Simplifying the Measurement of Inventory , which applies to inventory measured using first-in, first-out or average cost. The guidance in this update states that inventory within its scope shall be measured at the lower of cost or net realizable value, and when the net realizable value of inventory is lower than its cost, the difference shall be recognized as a loss in earnings. The Company adopted the accounting guidance as of January 1, 2017. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. Standards not yet adopted In May 2017, the FASB issued ASU 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting. The guidance in this ASU applies to all entities that change the terms or conditions of a share-based payment award. The amendments provide clarity and reduces diversity in practice as well as cost and complexity when applying the guidance in Topic 718, Compensation – Stock Compensation, to the modification of the terms and conditions of a share-based payment award. The amendments in ASU 2017-09 include guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The new standard is effective for the Company beginning on January 1, 2018 and should be applied prospectively to awards modified on or after the adoption date. The Company has concluded that the adoption of this ASU will not have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendments affect all companies and other reporting organizations that must determine whether they have acquired or sold a business. The amendments are intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments provide a more robust framework to use in determining when a set of assets and activities is a business. The new standard is effective for the Company beginning on January 1, 2018. The Company has concluded that the adoption of this ASU will not have a material impact on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statements of Cash Flows (Topic 230): Restricted Cash. The guidance in this ASU requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. As a result, amounts generally described as restricted cash and restricted cash equivalents should 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 new standard is effective for the Company beginning on January 1, 2018 and should be applied on a retrospective basis. The Company has concluded that the adoption of this ASU will not have a material impact on its consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The guidance in this ASU requires entities to recognize at the transaction date the income tax consequences of intercompany asset transfers other than inventory. The new standard is effective for the Company beginning on January 1, 2018. The Company has concluded that the adoption of this ASU will not have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which requires lessees to recognize the assets and liabilities arising from leases on the balance sheet. This new ASU will require the lessee to recognize a lease liability equal to the present value of the lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases longer than 12 months. For leases with a term of 12 month or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities and recognize the lease expense for such leases generally on a straight-line basis over the lease term. Under the new guidance, the Company will revise its leasing policies to require most of the leases, where the Company is the lessee, to be recognized on the balance sheet as a lease and lease liability. Further, the Company will separate leases from other contracts where the Company is either the lessor or lessee when the rights conveyed under the contracts indicate there is a lease. The Company is evaluating the effect ASU 2016-02 will have on its consolidated financial statements. The Company anticipates that its assets and liabilities will increase by a significant amount. The new standard is effective for the Company beginning on January 1, 2019. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which will replace most existing revenue recognition guidance in GAAP. The guidance in this ASU requires an entity to recognize the amount of revenue that it expects to be entitled for the transfer of promised goods or services to customers. The Company’s services and rental contracts are primarily short-term in nature, and therefore, the Company has concluded that the adoption of this ASU will not have a material impact on the consolidated financial statements, other than the additional disclosure requirements. The new standard is effective for the Company beginning on January 1, 2018. Subsequent Events In accordance with authoritative guidance, the Company has evaluated and disclosed all material subsequent events that occurred after the balance sheet date, but before financial statements were issued .

In February 2017, the Company amended its credit facility to, among other things, reduce the size of the credit facility from $400.0 million to $300.0 million (with a $100.0 million accordion feature) and amend the financial covenants, in part to suspend the interest coverage ratio until the third quarter of 2017. In October 2017, the Company amended and restated its revolving credit facility to, among other things, extend its maturity to October 2022. The borrowing base under the credit facility is calculated based on a formula referencing the borrower’s and the subsidiary guarantors’ eligible accounts receivable, eligible inventory and eligible premium rental drill pipe less reserves. Availability under the credit facility is the lesser of (i) the commitments, (ii) the borrowing base and (iii) the highest principal amount permitted to be secured under the indenture governing the 7 1/8% senior unsecured notes due 2021. At December 31, 2017, the borrowing base was $2 73.2 million and the Company had $35.3 million of letters of credit outstanding under the revolving credit facility. The borrowing base may increase or decrease as a result of, among other things, changes to the Company’s consolidated tangible assets. The credit agreement contains various covenants, including, but not limited to, limitations on the incurrence of indebtedness, permitted investments, liens on assets, making distributions, transactions with affiliates, merger, consolidations, dispositions of assets and other provisions customary in similar types of agreements. Senior Unsecured Notes In August 2017, the Company issued $500 million of 7 3/4% senior unsecured notes due September 2024 in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act.

Stock-Based Compensation And Long-Term [Abstract]
Stock-Based and Long-Term Compensation	(6) Stock-Based and Long-Term Compensation The Company is authorized to grant restricted stock units, stock options, performance share units, and other cash and stock awards under the Long-Term Incentive Program (LTIP). The Compensation Committee determines the recipients of the equity awards, the type of awards made, the required performance measures, and the timing and duration of each grant. At December 31, 2017 , 7,350,000 shares of the Company’s common stock were available for future grants under the plan. Total stock-based compensation expense and the associated tax benefits are as follows (in thousands): Compensation Expense Years ended December 31, 2017 2016 2015 Stock options $ 4,289 $ 4,870 $ 3,663 Restricted stock - 382 9,219 Restricted stock units 21,899 24,762 19,699 Performance share units 9,740 10,167 12,991 Total $ 35,928 $ 40,181 $ 45,572 Tax Benefit Years ended December 31, 2017 2016 2015 Stock options $ 995 $ 1,802 $ 1,355 Restricted stock - 141 3,411 Restricted stock units 5,081 9,162 7,289 Total $ 6,076 $ 11,105 $ 12,055 Total stock-based compensation expense is reflected in general and administrative expenses in the consolidated statements of operations. Stock Options Stock options are granted with an exercise price equal to the market price of our ordinary shares at the date of grant. The stock options generally vest in equal installments over three years and expire in ten years from the grant date. Non-vested stock options are generally forfeited upon termination of employment. The Company recognizes compensation expense for stock option grants based on the fair value at the date of grant using the Black-Scholes-Merton option pricing model. The Company uses historical data, among other factors, to estimate the expected volatility and the expected life of the stock options. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected life of the stock option. The dividend yield is based on our historical and projected dividend payouts. The weighted average fair values of stock options granted and the assumptions used in estimating those fair values are as follows: Years ended December 31, 2017 2016 2015 Weighted average fair value of stock options granted $ 8.36 $ 3.61 $ 6.25 Black-Scholes-Merton Assumptions: Risk free interest rate 1.96 % 1.46 % 1.33 % Expected life (years) 6 5 5 Volatility 48.22 % 55.72 % 47.07 % Dividend yield - 3.28 1.30 The following table summarize s stock option activity for 2017 : Number of Options Weighted Average Option Price Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding as of December 31, 2016 6,010,834 $ 19.23 6.0 $ 14,145 Granted 351,551 $ 18.03 Exercised (5,998) $ 16.56 Expired (217,734) $ 30.79 Outstanding as of December 31, 2017 6,138,653 $ 18.75 5.4 $ - Exercisable as of December 31, 2017 4,389,720 $ 21.37 4.3 $ - Options expected to vest as of December 31, 2017 1,748,933 $ 12.18 8.1 $ - The total intrinsic value of stock options exercised during 2017, 2016 and 2015 was $0 , $ 0.3 million and $2.3 million, respectively. The Company received $0.1 million, $0.5 million and $8.8 million during 2017, 2016 and 2015 , respectively, from employee stock option exercises. The Company has reported tax benefits of $ 0 , $0. 1 million and $0.9 million from the exercise of stock options for 2017, 2016 and 2015 , respectively. The following table summarizes non-veste d stock option activity for 2017 : Number of Options Weighted Average Grant Date Fair Value Non-vested as of December 31, 2016 2,339,593 $ 11.97 Granted 351,551 $ 18.03 Vested (942,211) $ 13.85 Non-vested as of December 31, 2017 1,748,933 $ 12.18 At December 31, 2017 , the unrecognized compensation expense related to non-vested stock options was $4.3 million. The Company expects to recognize $3.2 million and $1.1 m illion of compensation expense associated with these options during 2018 and 2019 , respectively. Restricted Stock Units R estri cted stock unit awards (RSUs) vest in equal annual installments over three years. On the vesting date, each RSU is converted to one share of the Company’s common stock having an aggregate value determined by the Company’s closing stock price on the vesting date. Holders of RSUs are not entitled to any rights of a stockholder, such as the right to vote shares. Each non-employee director is issued annually a number of RSUs having an aggregate dollar value determined by the Company’s Board of Directors. The exact number of RSUs granted is determined by dividing the aggregate dollar value determined by the Company’s Board of Directors by the fair market value of the Company’s common stock on the day of the annual stockholders’ meeting. If the director’s election occurs at a time other than at the annual meeting, the director will receive a pro-rata number of RSUs based on the number of months between his or her election date and the anniversary of the last annual stockholder meeting. Each RSU granted prior to 2013 represents the right to receive from the Company, within 30 days of the date the director ceases to serve on the Board, one share of the Company’s common stock. The RSUs granted will vest and pay out in shares of the Company’s common stock in the year following the grant date on the date of Company’s annual meeting. The following table summarizes RSU activity for 2017 : Number of RSUs Weighted Average Grant Date Fair Value Non-vested as of December 31, 2016 3,686,292 $ 14.10 Granted 1,352,799 $ 17.37 Vested (1,501,342) $ 15.51 Forfeited (345,749) $ 13.67 Non-vested as of December 31, 2017 3,192,000 $ 14.87 At December 31, 20 17 , there was $21.2 million of unrecognized compensation expense related to unvested RSUs. The Company expects to recognize $13.8 million, $7.1 million, and $0.3 m illion associated with unvested RSUs for 2018, 2019, and 2020 , respectively. Performance Share Units The Company has issued performance share units (PSUs) to its employees as part of the Company’s long-term incentive program. There is a three -year performance period associated with each PSU grant. The two performance measures applicable to all participants are the Company’s return on invested capital and total stockholder return relative to those of the Company’s pre-defined “peer group.” If the participant has met specified continued service requirements, the PSUs will settle in cash or a combination of cash and up to 50 % of equivalent value in the Company’s common stock, at the discretion of the Compensation Committee of the Board of Directors. At December 31, 2017 , there were 344,177 PSUs outstanding ( 129,606 , 116,324 and 98,247 related to performance periods ending December 31, 2017, 2018 and 2019 , respectively). The Company has recorded both current and long-term liabilities for this liability-based compensation award. Employee Stock Purchase Plan (ESPP) Eligible employees are allowed to purchase shares of the Company’s common stock at a discount during six-month offering periods beginning on January 1 st and July 1 st of each year and ending on June 30 and December 31 of each year, respectively. The following table summarizes ESPP activity (in thousands except shares): Years ended December 31, 2017 2016 2015 Cash received for shares issued $ 3,074 $ 3,681 $ 4,803 Compensation expense $ 542 $ 1,492 $ 835 Shares issued 360,465 290,987 332,467 401(k)/Profit Sharing Plan The Company maintains a defined contribution profit sharing plan for employees who have satisfied minimum service requirements. Employees may contribute up to 75 % of their eligible earnings to the plan subject to the contribution limitations imposed by the Internal Revenue Service. The Company provides a nondiscretionary match of 100 % of an employee’s contributions to the plan, up to 4 % of the employee’s salary. The Company made contributions of $ 8.4 million, $ 8.7 million and $ 13.9 million 2017, 2016 and 2015 , respectively. Non-Qualified Deferred Compensation Plans The Company has a non-qualified deferred compensation plan which allows senior management to defer up to 75 % of their base salary, up to 100 % of their bonus, up to 100 % of the cash portion of their PSU compensation and up to 100% of the vested RSUs to the plan. The Company also has a non-qualified deferred compensation plan for its non-employee directors which allows each director to defer up to 100 % of their cash compensation paid by the Company and up to 100% of the vested RSUs to the plan. Payments are made to participants based on their annual enrollment elections and plan balances. The following table summarizes deferred compensation balances (in thousands): December 31, Balance sheet location 2017 2016 Deferred compensation assets Intangible and other long-term assets, net $ 14,187 $ 12,360 Deferred compensation liabilities, short-term Accounts payable $ 1,253 $ 1,115 Deferred compensation liabilities, long-term Other long-term liabilities $ 21,085 $ 18,489 Supplemental Executive Retirement Plan The Company has a supplemental executive retirement plan (SERP).

Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017 and the transition of U.S. international taxation from a worldwide tax system to a modified territorial system. As a result, we recorded a provisional income tax benefit of $76.5 million during the fourth quarter of 2017. The provisional amount related primarily to the remeasurement of certain deferred tax assets and liabilities, based on the rates at which they are expected to reverse in the future. Additional work is necessary for a more detailed analysis of our deferred tax assets and liabilities. Any subsequent adjustments to the provisional amount will be reported as component of income tax expense (benefit) in the reporting period in which any such adjustments are determined. The tax effects of temporary differences that give rise to significant components of deferred income tax assets and liabilities are as follows (in thousands): December 31, 2017 2016 Deferred tax assets: Allowance for doubtful accounts $ 5,717 $ 9,172 Operating loss and tax credit carryforwards 118,687 85,383 Compensation and employee benefits 38,261 59,351 Decommissioning liabilities 26,875 40,994 Other 28,807 51,069 218,347 245,969 Valuation allowance (8,722) (6,722) Net deferred tax assets 209,625 239,247 Deferred tax liabilities: Property, plant and equipment 177,231 352,683 Notes receivable 12,977 14,796 Goodwill and other intangible assets 64,746 98,868 Other 15,729 16,511 Deferred tax liabilities 270,683 482,858 Net deferred tax liability $ 61,058 $ 243,611 At December 31, 2017 , the Company had $ 135.5 million in U.S. net operating loss carryforwards, which are ava ilable to reduce future taxab le income. The expiration date for utilization of the U.S. loss carryforwards is 2037. At December 31, 2017 , the Company also had various state net operating loss carryforwards with expiration dates from 2018 to 2037. A net deferred tax asset of $ 24.5 million reflects the expected future tax benefit for the state loss carryforwards. At December 31, 2017, the Company also had a U.S. foreign tax credit carryforward of $55.9 million with expiration dates from 2021 to 2027. The net deferred tax assets reflect management’s estimate of the amount that will be realized from future profitability and the reversal of taxable temporary differences that can be predic ted with reasonable certainty. A valuation allowance has been recognized on a portion of the state net operating loss carryforward deferred tax asset. After considering all availab le evidence at December 31, 2017 , the Company determined that it was more likely than not that a portion of the carryforward would not be realized. Accordingly, the Company increased deferred income tax expense by an additional $2.0 million of the valuation allowance. Th e Company has not provided income tax expense on earnings of its foreign subsidiaries, since the Company has reinvested or expects to reinvest undistributed earnings outside the U.S. indefinitely. At December 31, 2017 , the Company’s foreign subsidiaries had an overall accumulated deficit in earnings. The Company does not intend to repatriate the earnings of its profitable foreign subsidiaries. The Company has not provided U.S. income taxes for such earnings, except to the extent that such earnings were previously subject to U.S. income taxes. These earnings could become subjec t to U.S. income tax if repatriated . It is not practicable to estimate the amount of taxes that might be payable on such undistributed earnings. The U.S. Tax Reform imposes a tax on post-1986 earnings of non-U.S. affiliates that have not been repatriated for purposes of US federal income tax, with those earnings taxed at rates of 15.5% for earnings reflected by cash and cash equivalent items and 8% for other assets. The cash tax effects of this deemed repatriation can be remitted in installments over an eight-year period. We estimate the impact of this tax will not be material to our financial position. The Company files income tax returns in the U.S., including federal and various state filings, and certain foreign jurisdictions. The number of years that are open under the statute of limitations and subject to audit varies depending on the tax jurisdiction. The Company remains subject to U.S. federal tax examinations for years after 2012. The Company had unrecognized tax benefits of $30. 7 million, $ 29. 9 million and $ 29 . 7 million as of December 31, 2017 , 2016 and 2015 , respectively, all of which would impact the Company’s effective tax rate if recognized. The activity in unrecognized tax benefits is as follows (in thousands): Years ended December 31, 2017 2016 2015 Unrecognized tax benefits, December 31, 2016, 2015 and 2014, respectively $ 29,956 $ 29,715 $ 30,344 Additions based on tax positions related to prior years 5,576 6,874 6,752 Reductions based on tax positions related to prior years (4,671) (3,582) - Reductions as a result of a lapse of the applicable statute of limitations (205) (3,051) - Reductions relating to settlements with taxing authorities - - (7,381) Unrecognized tax benefits, December 31, 2017, 2016 and 2015, respectively $ 30,656 $ 29,956 $ 29,715 The Company recorded $2.2 m illion, $2.5 million and $1.0 million of interest and penalties for 2017, 2016 and 2015 , respectively, classified as a component of income tax expense in the consolidated statements of operations. The amounts in the table above include cumulative accrued interest and penalties of $9.7 m illion, $7.4 million and $4.6 million at December 31, 2017, 2016 and 2015 , respectively, which are included in other non-current liabilities on the consolidated balance sheets.

Segment Information [Abstract]
Segment Information	(8) Segment Information Business Segments The Drilling Products and Services segment rents and sells bottom hole assemblies, premium drill pipe, tubulars and specialized equipment for use with onshore and offshore oil and gas well drilling, completion, production and workover activities. It also provides on-site accommodations and machining services. The Onshore Completion and Workover Services segment provides pressure pumping services used to complete and stimulate production in new oil and gas wells, fluid handling services and well servicing rigs that provide a variety of well completion, workover and maintenance services. The Production Services segment provides intervention services such as coiled tubing, cased hole and mechanical wireline, hydraulic workover and snubbing, production testing and optimization, and remedial pumping services. The Technical Solutions segment provides services typically requiring specialized engineering, manufacturing or project planning, including well containment systems, stimulation and sand control services and well plug and abandonment services. It also includes production handling arrangements and the production and sale of oil and gas. Effective as of the fourth quarter of 2017, the Company’s management changed the measurement used to evaluate the performance of its reportable segments from income or loss from operations including allocated corporate expenses to income or loss from operations excluding allocated corporate expenses. The segment measure is calculated as follows: segment revenues less segment operating expenses, depreciation, depletion, amortization and a ccretion expense and reduction in value of assets. The Company uses this segment measure to evaluate its reportable segments because it is the measure that is most consistent with how the Company organizes and manages its business operations. Corporate and other costs primarily include expenses related to support functions, salaries and benefits for corporate employees and stock-based compensation expense. Summarized financial information for the Company’s segment s is as follows (in thousands): 2017 Onshore Drilling Completion Products and and Workover Production Technical Corporate and Consolidated Services Services Services Solutions Other Total Revenues $ 293,690 $ 935,183 $ 372,781 $ 272,422 $ - $ 1,874,076 Cost of services and rentals (exclusive of depreciation, depletion, amortization and accretion) 128,381 791,581 303,256 175,477 - 1,398,695 Depreciation, depletion, amortization and accretion 131,394 193,098 78,999 29,506 5,719 438,716 General and administrative expenses 51,265 44,766 48,655 51,679 99,142 295,507 Reduction in value of assets 1,356 4,684 - 8,115 - 14,155 Income/(loss) from operations (18,706) (98,946) (58,129) 7,645 (104,861) (272,997) Interest income (expense), net - - - 3,567 (105,022) (101,455) Other expense - - - - (3,299) (3,299) Income/(loss) from continuing operations before income taxes $ (18,706) $ (98,946) $ (58,129) $ 11,212 $ (213,182) $ (377,751) 2016 Onshore Drilling Completion Products and and Workover Production Technical Corporate and Consolidated Services Services Services Solutions Other Total Revenues $ 293,543 $ 523,965 $ 348,363 $ 284,176 $ - $ 1,450,047 Cost of services and rentals (exclusive of depreciation, depletion, amortization and accretion) 136,719 515,784 276,223 194,548 - 1,123,274 Depreciation, depletion, amortization and accretion 159,937 207,038 93,878 42,393 6,725 509,971 General and administrative expenses 64,182 48,837 49,687 65,299 118,601 346,606 Reduction in value of assets 48,903 190,835 235,067 25,600 - 500,405 Loss from operations (116,198) (438,529) (306,492) (43,664) (125,326) (1,030,209) Interest income (expense), net - - (1,343) 3,553 (94,963) (92,753) Other income - - - - 22,621 22,621 Loss from continuing operations before income taxes $ (116,198) $ (438,529) $ (307,835) $ (40,111) $ (197,668) $ (1,100,341) 2015 Onshore Drilling Completion Products and and Workover Production Technical Corporate and Consolidated Services Services Services Solutions Other Total Revenues $ 547,530 $ 934,274 $ 795,215 $ 497,546 $ - $ 2,774,565 Cost of services and rentals (exclusive of depreciation, depletion, amortization and accretion) 178,629 773,119 612,578 301,486 - 1,865,812 Depreciation, depletion, amortization and accretion 186,047 223,626 135,310 61,013 6,151 612,147 General and administrative expenses 95,512 78,930 109,959 98,894 127,413 510,708 Reduction in value of assets 40,237 783,229 790,517 124,904 - 1,738,887 Income (loss) from operations 47,105 (924,630) (853,149) (88,751) (133,564) (1,952,989) Interest income (expense), net - - (2,013) 1,707 (97,012) (97,318) Other expense - - - - (9,476) (9,476) Income (loss) from continuing operations before income taxes $ 47,105 $ (924,630) $ (855,162) $ (87,044) $ (240,052) $ (2,059,783) Identifiable Assets Onshore Drilling Completion Products and and Workover Production Technical Corporate and Consolidated Services Services Services Solutions Other Total December 31, 2017 $ 662,968 $ 1,501,214 $ 512,256 $ 377,549 $ 56,238 $ 3,110,225 December 31, 2016 $ 824,287 $ 1,534,008 $ 598,167 $ 439,521 $ 74,272 $ 3,470,255 December 31, 2015 $ 1,144,201 $ 1,913,408 $ 1,029,902 $ 789,957 $ 36,776 $ 4,914,244 Capital Expenditures Onshore Drilling Completion Products and and Workover Production Technical Corporate and Consolidated Services Services Services Solutions Other Total December 31, 2017 $ 27,219 $ 115,415 $ 7,860 $ 13,296 $ 1,143 $ 164,933 December 31, 2016 $ 35,413 $ 20,094 $ 20,848 $ 3,829 $ 364 $ 80,548 December 31, 2015 $ 123,075 $ 102,061 $ 76,597 $ 52,733 $ 3,760 $ 358,226 Geographic Segments The Company attributes revenue to various countries based on the location where services are performed or the destination of the drilling products or equipment sold or rented.

Commitments And Contingencies [Abstract]
Commitments And Contingencies	(9) Commitments and Contingencies The Company leases most of its office, service and assembly facilities under operating leases. In addition, the Company also leases certain assets used in providing services under operating leases. The leases expire at various dates over an extended period of time. Total rent expense was $ 15.3 million, $ 24.1 million and $ 29.6 million during 2017 , 2016 and 2015 , respectively. Future minimum lease payments under non-cancelable leases for the five years ending December 31, 201 8 through 20 22 and thereafter are as follows: $ 24.6 million, $ 18.5 million, $ 11.8 million, $ 9.4 million and $ 16.4 million, respectively. Due to the nature of the Company’s business, the Company is involved, from time to time, in routine litigation or subject to disputes or claims regarding its business activities. Legal costs related to these matters are expensed as incurred. However, based on current circumstances, the Company does not believe that the ultimate resolution of these proceedings, after considering available defenses and any insurance coverage or indemnification rights, will have a material adverse effect on its financial position, results of operations or cash flows.

The Company entered into separate trust agreements, subject to general creditors, to segregate assets of each plan and reports the accounts of the trusts in its consolidated financial statements. These investments are reported at fair value based on unadjusted quoted prices in active markets for identifiable assets and observable inputs for similar assets and liabilities, which represent Levels 1 and 2, respectively, in the fair value hierarchy. At December 31, 2016, the Company had three interest rate swap agreements related to its fixed rate debt maturing in 2021 for notional amounts of $100 million each (see note 11 ). In January 2017, the Company sold these interest rate swaps to the counterparties for a net amount of $0.8 million. The following table reflects the fair value measurements used in testing the impairment of long-lived assets and goodwill (in thousands): Year ended December 31, 2016 Impairment Fair Value Goodwill $ 330,500 $ 668,864 Intangible assets $ 68,865 $ - Property, plant and equipment, net $ 74,938 $ 294,457 Fair value is measured as of the impairment date using Level 3 inputs.

Derivative Financial Instruments [Abstract]
Derivative Financial Instruments	(11) Derivative Financial Instruments The Company had three interest rate swaps for notional amounts of $100 million each, related to its 7 1/8% senior unsecured notes maturing in December 2021. In January 2017, the Company sold these interest rate swaps to the counterparties for a net amount of $0.8 million. The remaining balance of the derivative asset is being amortized to interest expense over the remaining term of the related notes. For the year ended December 31, 2017, $2. 0 million of expense related to the amortization of the remaining derivative asset was recorded. The location and effect of the derivative instrument on the consolidated statements of operations presented on a pre-tax basis is as follows (in thousands): Years ended December 31, Effect of derivative asset Location of (gain) loss recognized 2016 2015 Interest rate swap Interest expense, net $ 2,306 $ (1,932) Hedged item - debt Interest expense, net (3,980) (790) $ (1,674) $ (2,722) During 2016 and 2015 $ 1.7 million and $ 2.7 million of interest income, respectively, was related to the ineffectiveness associated with these fair value hedges. Hedge ineffectiveness represents the difference between the changes in fair value of the derivative instruments and the changes in fair value of the fixed rate debt attributable to changes in the benchmark interest rate.

The Company reports its operating results in four business segments: Drilling Products and Services; Onshore Completion and Workover Services; Production Services; and Technical Solutions. Given the Company’s long-term strategy of expanding geographically, the Company also provides supplemental segment revenue information in three geographic areas: U.S. land; Gulf of Mexico; and International.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Major Customers and Concentration of Credit Risk	Major Customers and Concentration of Credit Risk The majority of the Company’s business is conducted with major and independent oil and gas companies. The Company evaluates the financial strength of its customers and provides allowances for probable credit losses when deemed necessary. The market for the Company’s services and products is the oil and gas industry in the U.S. land and Gulf of Mexico areas and select international market areas. Oil and gas companies make capital expenditures on exploration, development and production operations. The level of these expenditures historically has been characterized by significant volatility. The Company derives a large amount of revenue from a small number of major and independent oil and gas companies. Anadarko accounted for approximately 13% and 11% of the Company’s revenues in 2017 and 2016, respectively, primarily within the Onshore Completion and Workover Services segment. There were no customers that exceeded 10% of our total revenues in 2015 . The Company’s assets that are potentially exposed to concentrations of credit risk consist primarily of cash , cash equivalents and trade receivables. The financial institutions in which the Company transacts business are large, investment grade financial institutions which are “well capitalized” under applicable regulatory capital adequacy guidelines , thereby minimizing it s exposure to credit risks for deposits in excess of federally insured amounts and for failure to perform as the counterparty on interest rate swap agreements. The Company periodically evaluates the creditworthiness of financial institutions that may serve as a counterparty to its derivative instruments .
Cash Equivalents	Cash Equivalents The Company considers all short-term investments with a maturity of 90 days or less when purchased to be cash equivalents.
Accounts Receivable and Allowances	Accounts Receivable and Allowances Trade accounts receivable are recorded at the invoiced amount or the earned amount but not yet invoiced and do not bear interest. The Company maintains allowances for estimated uncollectible receivables, including bad debts and other items. The allowance for doubtful accounts is based on the Company’s best estimate of probable uncollectible amounts in existing accounts receivable. The Company determines the allowance based on historical write-off experience and specific identification.
Inventory	Inventory Inventories are stated at the lower of cost or net realizable value. The Company applies net realizable value and obsolescence to the gross value of the inventory. Cost is determined using the first-in, first-out or weighted-average cost methods for finis hed goods and work-in-process. Supplies and consumables consist principally of products used in the Company’s services provided to its customers. The components of inventory balances are as follows (in thousands): December 31, 2017 December 31, 2016 Finished goods $ 61,764 $ 49,888 Raw materials 13,727 17,948 Work-in-process 6,174 5,214 Supplies and consumables 24,923 30,029 Total $ 106,588 $ 103,079
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost, except for assets for which reduction in value is recorded during the period and assets acquired using purchase accounting, which are recorded at fair value as of the date of acquisition. With the exception of certain marine assets and oil and natural gas property, depreciation is computed using the straight line method over the estimated useful lives of the related assets as follows: Buildings and improvements 5 to 40 years Marine vessels and equipment 5 to 25 years Machinery and equipment 2 to 25 years Automobiles, trucks, tractors and trailers 3 to 10 years Furniture and fixtures 2 to 10 years The Company follows the successful efforts method of accounting for its investment in oil and natural gas property. Under the successful efforts method, the costs of successful exploratory wells and leases containing productive reserves are capitalized. Costs incurred to drill and equip developmental wells, including unsuccessful wells, are capitalized. Other costs such as geological and geophysical costs and the drilling costs of unsuccessful exploratory wells are expensed. Leasehold and well costs are depleted on a units-of-production basis based on the estimated remaining equivalent oil and gas reserves.
Reduction In Value Of Long-Lived Assets	Reduction in Value of Long-Lived Assets Long-lived assets, such as property, plant and equipment and purchased intangibles subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is assessed by a comparison of the carrying amount of such assets to their fair value calculated, in part, by the estimated undiscounted future cash flows expected to be generated by the assets. Cash flow estimates are based upon, among other things, historical results adjusted to reflect the best estimate of future market rates, utilization levels, and operating performance. Estimates of cash flows may differ from actual cash flows due to, among other things, changes in economic conditions or changes in an asset’s operating performance. The Company’s assets are grouped by subsidiary or division for the impairment testing, which represent the lowest level of identifiable cash flows. If the asset grouping’s fair value is less than the carrying amount of those items, impairment losses are recorded in the amount by which the carrying amount of such assets exceeds the fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value less estimated costs to sell. The net carrying value of assets not fully recoverable is reduced to fair value. The estimate of fair value represents the Company’s best estimate based on industry trends and reference to market transactions and is subject to variability. The oil and gas industry is cyclical and estimates of the period over which future cash flows will be generated, as well as the predictability of these cash flows, can have a significant impact on the carrying values of these assets and, in periods of prolonged down cycles, may result in impairment charges. See note 3 for a discussion of the reduction in value of long-lived assets recorded during 2017, 2016 and 2015.
Goodwill	Goodwill The following table summarizes the activity for the Company’s goodwill (in thousands): Onshore Drilling Completion Products and Workover Production and Services Services Services Total Balance, December 31, 2015 $ 141,282 $ 723,550 $ 275,269 $ 1,140,101 Reduction in value of assets - (140,000) (190,500) (330,500) Foreign currency translation adjustment (5,321) - (363) (5,684) Balance, December 31, 2016 135,961 583,550 84,406 803,917 Foreign currency translation adjustment 2,532 - 1,411 3,943 Balance, December 31, 2017 $ 138,493 $ 583,550 $ 85,817 $ 807,860 During the first quarter of 2017, the Company adopted the Financial Accounting Standards Board (FASB) update (ASU) 2017-04, Intangibles- Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in the ASU eliminate Step 2 from the goodwill impairment test. The annual or interim goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The Company performs the goodwill impairment test on an annual basis as of October 1 st or on an interim basis if events or circumstances indicate that the fair value of the asset has decre ased below its carrying value. In order to estimate the fair value of the reporting units (which is consistent with the reported business segments), the Company used a weighting of the discounted cash flow method and the public company guideline method of determining fair value of each reporting unit. The Company weighted the discounted cash flow method 80 % and the public company guideline method 20 % due to differences between the Company’s reporting units and the peer companies’ size, profitabilit y and diversity of operations. These fair value estimates were then compared to the carrying value of the reporting units. If the fair value of the reporting unit exceeds the carrying amount, no impairment loss is recognized. If the estimated fair value of the reporting unit is below the carrying value, then an impairment is recorded, which represents the amount by which a reporting unit’s carrying value exceeds its fair value. The Company uses all available information to estimate fair value of the reporting units, including discounted cash flows. A significant amount of judgment was involved in performing these evaluations since the results are based on estimated future events. See note 3 for a discussion of the reduction in value of goodwill recorded during 2016 and 2015. At December 31, 2017 and 2016 , the Company’s accumulated reduction in value of goodwill was $1,748.2 million .
Notes Receivable	Notes Receivable The Company’s wholly owned subsidiary, Wild Well, has decommissioning obligations related to its ownership of the Bullwinkle platform. Notes receivable consist of a commitment from the seller of the platform towards its eventual abandonment. Pursuant to an agreement with the seller, the Company will invoice the seller an agreed upon amount at the completion of certain decommissioning activities. The gross amount of this obligation totaled $ 115.0 million and is recorded at present value using an effective interest rate of 6.58 %. The related discount is amortized to interest income based on the expected timing of the platform’s removal. The Company recorded interest income related to notes receivable of $ 3.6 million, $ 3.6 million and $1.7 million during 2017 , 2016 and 201 5 , respectively.
Intangible and Other Long-Term Assets	Intangible and Other Long-Term Assets Intangible assets consist of the following (in thousands): December 31, 2017 2016 Estimated Gross Accumulated Net Gross Accumulated Net Useful Lives Amount Amortization Balance Amount Amortization Balance Customer relationships 17 years $ 165,036 $ (62,930) $ 102,106 $ 164,603 $ (52,747) $ 111,856 Tradenames 10 years 30,732 (17,188) 13,544 30,519 (14,123) 16,396 Non-compete agreements 3 years 4,299 (3,241) 1,058 2,790 (2,718) 72 Total $ 200,067 $ (83,359) $ 116,708 $ 197,912 $ (69,588) $ 128,324 Amortization expense was $ 12.7 million, $16.2 million and $23.0 million during 2017 , 2016 and 2015 , respectively. Based on the carrying values of intang ible assets at December 31, 2017 , amortization expen se for the next five years (2018 through 2022 ) is estimated to b e $ 12.6 million per year. Intangible and other long-term assets, net included $20.5 million and $58.5 million of escrowed cash at December 31, 2017 and 2016 , respectively, primarily related to the future decommissioning obligations of the Bullwinkle platform. During 2017, $30.6 million was released from the escrow account.
Decommissioning Liabilities	Decommissioning Liabilities The Company’s decommissioning liabilities associated with the Bullwinkle platform and its related assets consist of costs related to the plugging of wells, the removal of the related platform and equipment, and site restoration. The Company reviews the adequacy of its decommissioning liabilities whenever indicators suggest that the estimated cash flows needed to satisfy the liability have changed materially. The following table summarizes the activity for the Company’s decommissioning liabilities (in thousands): December 31, 2017 2016 Decommissioning liabilities, December 31, 2016 and 2015, respectively $ 123,677 $ 117,942 Revisions in estimated timing and cash flows - (2,132) Accretion 6,837 6,959 Liability acquisitions and dispositions (117) 908 Total decommissioning liabilities, December 31, 2017 and 2016, respectively $ 130,397 $ 123,677
Revenue Recognition	Revenue Recognition Products and services are generally sold based upon purchase orders or contracts with customers that include fixed or determinable prices. Revenue is recognized when services or equipment are provided and collectability is reasonably assured. The Company’s drilling products and services are billed on a day rate basis, and revenue from the sale of equipment is recognized when the title to the equipment has been transferred. Reimbursements from customers for the cost of drilling products and services that are damaged or lost down-hole are reflected as revenue at the time of the incident. The Company recognizes oil and gas revenue from its interests in producing wells as oil and natural gas is sold. Taxes collected from customers and remitted to governmental authorities are reported on a net basis in the Company’s financial statements.
Income Taxes	Income Taxes The Company accounts for income taxes and the related accounts under the asset and liability method. Deferred income taxes reflect the impact of temporary differences between amounts of assets and liabilities for financial reporting purposes and such amounts as measured by tax laws and rates that are in effect when the temporary differences are expected to reverse. The effect of a change in tax rates on the deferred income taxes is recognized in income in the period in which the change occurs. A valuation allowance is recorded when management believes it is more likely than not that at least some portion of any deferred tax asset will not be realized. It is the Company’s policy to recognize interest and applicable penalties related to uncertain tax positions in income tax expense.
Earnings Per Share	Earnings per Share Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed in the same manner as basic earnings per share except that the denominator is increased to include the number of additional shares of common stock that could have been outstanding assuming the exercise of stock options and conversion of restricted stock units. During 2017, 2016 and 2015, the Company incurred losses from continuing operations; therefore the impact of any incremental shares would be anti-dilutive.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or the price paid to transfer a liability in an orderly transaction between market participants at the measurement date. Inputs used in determining fair value are characterized according to a hierarchy that prioritizes those inputs based on the degree to which they are observable. The three input levels of the fair value hierarchy are as follows: Level 1 : Unadjusted quoted prices in active markets for identical assets and liabilities; Level 2 : Observable inputs other than those included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical assets or liabilities in inactive markets or model-derived valuations or other inputs that can be corroborated by observable market data; and Level 3 : Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability.
Financial Instruments	Financial Instruments The fair value of the Company’s financial instruments of cash equivalents, accounts receivable, accounts payable, accrued expenses and borrowings under its credit facility approximates their carrying amounts due to their short maturity or market interest rates. The fair value of the Company’s debt was $ 1,347.0 million and $ 1,307.6 million at December 31, 2017 and 2016 , respectively, and was categorized as Level 1 in the fair value hierarchy. The fair value of these debt instruments is determined by reference to the market value of the instrument as quoted in an over-the-counter market.
Foreign Currency	Foreign Currency Results of operations for foreign subsidiaries with functional currencies other than the U.S. dollar are translated using average exchange rates during the period. Assets and liabilities of these foreign subsidiaries are translated using the exchange rates in effect at the balance sheet dates, and the resulting translation adjustments are reported as accumulated other comprehensive loss in the Company’s stockholders’ equity. For international subsidiaries where the functional currency is the U.S. dollar, financial statements are remeasured into U.S. dollars using the historical exchange rate for most of the long-term assets and liabilities and the balance sheet date exchange rate for most of the current assets and liabilities. An average exchange rate is used for each period for revenues and expenses. These transaction gains and losses, as well as any other transactions in a currency other than the functional currency, are included in other income (expense) in the consolidated statements of operations in the period in which the currency exc hange rates change. During 2017 , 2016 and 2015 , the Company recorded foreign currency gains/(losses) of $(2.2) m illion, $23.5 million and $(9.6) million , respectively.
Stock-Based Compensation	Stock-Based Compensation The Company records compensation costs relating to share-based payment transactions and includes such costs in general and administrative expenses in the consolidated statements of operations. The cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award).
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. Interest rate swap agreements that are effective at hedging the fair value of fixed-rate debt agreements are designated and accounted for as fair value hedges. The Company also assesses, both at inception of the hedging relationship and on an ongoing basis, whether the derivatives used in hedging relationships are highly effective in offsetting changes in fair value.
Self Insurance Reserves	Self-Insurance Reserves The Company is self-insured, through deductibles and retentions, up to certain levels for losses under its insurance programs. The Company accrues for these liabilities based on estimates of the ultimate cost of claims incurred as of the balance sheet date. The Company regularly reviews the estimates of reported and unreported claims and provides for losses through reserves. The Company obtains actuarial reviews to evaluate the reasonableness of internal estimates for losses related to workers’ compensation, auto liability and group medical on an annual basis.
New Accounting Pronouncements	New Accounting Pronouncements Standards adopted In January 2017, the Financial Accounting Standards Board (FASB) issued accounting standards update (ASU) 2017-04, Intangibles- Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments eliminate Step 2 from the goodwill impairment test. The annual or interim goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The amendments should be applied on a prospective basis. The new standard is effective for the Company on January 1, 2020. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company adopted the accounting guidance as of January 1, 2017. The newly adopted accounting principle is preferable because it reduces the cost and complexity of evaluating goodwill for impairment. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which relates to the accounting for employee share-based payments. The guidance in this update addresses several aspects of the accounting for share-based payments, including income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The Company adopted the accounting guidance as of January 1, 2017. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330) – Simplifying the Measurement of Inventory , which applies to inventory measured using first-in, first-out or average cost. The guidance in this update states that inventory within its scope shall be measured at the lower of cost or net realizable value, and when the net realizable value of inventory is lower than its cost, the difference shall be recognized as a loss in earnings. The Company adopted the accounting guidance as of January 1, 2017. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. Standards not yet adopted In May 2017, the FASB issued ASU 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting. The guidance in this ASU applies to all entities that change the terms or conditions of a share-based payment award. The amendments provide clarity and reduces diversity in practice as well as cost and complexity when applying the guidance in Topic 718, Compensation – Stock Compensation, to the modification of the terms and conditions of a share-based payment award. The amendments in ASU 2017-09 include guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The new standard is effective for the Company beginning on January 1, 2018 and should be applied prospectively to awards modified on or after the adoption date. The Company has concluded that the adoption of this ASU will not have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendments affect all companies and other reporting organizations that must determine whether they have acquired or sold a business. The amendments are intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments provide a more robust framework to use in determining when a set of assets and activities is a business. The new standard is effective for the Company beginning on January 1, 2018. The Company has concluded that the adoption of this ASU will not have a material impact on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statements of Cash Flows (Topic 230): Restricted Cash. The guidance in this ASU requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. As a result, amounts generally described as restricted cash and restricted cash equivalents should 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 new standard is effective for the Company beginning on January 1, 2018 and should be applied on a retrospective basis. The Company has concluded that the adoption of this ASU will not have a material impact on its consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The guidance in this ASU requires entities to recognize at the transaction date the income tax consequences of intercompany asset transfers other than inventory. The new standard is effective for the Company beginning on January 1, 2018. The Company has concluded that the adoption of this ASU will not have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which requires lessees to recognize the assets and liabilities arising from leases on the balance sheet. This new ASU will require the lessee to recognize a lease liability equal to the present value of the lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases longer than 12 months. For leases with a term of 12 month or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities and recognize the lease expense for such leases generally on a straight-line basis over the lease term. Under the new guidance, the Company will revise its leasing policies to require most of the leases, where the Company is the lessee, to be recognized on the balance sheet as a lease and lease liability. Further, the Company will separate leases from other contracts where the Company is either the lessor or lessee when the rights conveyed under the contracts indicate there is a lease. The Company is evaluating the effect ASU 2016-02 will have on its consolidated financial statements. The Company anticipates that its assets and liabilities will increase by a significant amount. The new standard is effective for the Company beginning on January 1, 2019. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which will replace most existing revenue recognition guidance in GAAP. The guidance in this ASU requires an entity to recognize the amount of revenue that it expects to be entitled for the transfer of promised goods or services to customers. The Company’s services and rental contracts are primarily short-term in nature, and therefore, the Company has concluded that the adoption of this ASU will not have a material impact on the consolidated financial statements, other than the additional disclosure requirements. The new standard is effective for the Company beginning on January 1, 2018.
Subsequent Events	Subsequent Events In accordance with authoritative guidance, the Company has evaluated and disclosed all material subsequent events that occurred after the balance sheet date, but before financial statements were issued
