These financial statements and notes should be read in conjunction with the consolidated financial statements and notes thereto included in Superior Energy Services, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2016 , and Management’s Discussion and Analysis of Financial Condition and Results of Operations herein.  The financial information of Superior Energy Services, Inc. and subsidiaries (the Company) for the three and six months ended June 30, 2017 and 2016 has not been audited. However, in the opinion of management, all adjustments necessary to present fairly the results of operations for the periods presented have been included therein. Certain previously reported amounts have been reclassified to conform to the 2017 presentation. The results of operations for the first six months of the year are not necessarily indicative of the results of operations that might be expected for the entire year.

Fair Value Measurements [Abstract]
Fair Value Measurements	(7 ) 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.  Level 3 : Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability.  The following tables provide a summary of the financial assets and liabilities measured at fair value on a recurring basis (in thousands):     Fair Value at June 30, 2017  Level 1 Level 2 Level 3 Total  Intangible and other long-term assets, net  Non-qualified deferred compensation assets $ 369 $ 12,993 $ - $ 13,362  Accounts payable  Non-qualified deferred compensation liabilities $ - $ 1,098 $ - $ 1,098  Other long-term liabilities  Non-qualified deferred compensation liabilities $ - $ 19,571 $ - $ 19,571   Fair Value at December 31, 2016  Level 1 Level 2 Level 3 Total  Intangible and other long-term assets, net  Non-qualified deferred compensation assets $ 368 $ 11,992 $ - $ 12,360  Interest rate swaps $ - $ 8,579 $ - $ 8,579  Accounts payable  Non-qualified deferred compensation liabilities $ - $ 1,115 $ - $ 1,115  Other long-term liabilities  Non-qualified deferred compensation liabilities $ - $ 18,489 $ - $ 18,489  The Company’s non-qualified deferred compensation plans allow officers, certain highly compensated employees and non-employee directors to defer receipt of a portion of their compensation and contribute such amounts to one or more hypothetical investment funds. The Company entered into separate trust agreements, subject to general creditors, to segregate the assets of each plan and reports the accounts of the trusts in its condensed 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.  The fair value of the Company’s cash equivalents, accounts receivable and current maturities of long-term debt approximates their carrying amounts. The fair value of the Company’s long-term debt was approximately $ 1,271. 2 m illion and $ 1,307. 6 million as of June 30, 2017 and December 31, 201 6 , respectively. The fair value of these debt instruments is determined by reference to the market value of the instruments as quoted in over-the-counter markets, which are Level 1 inputs.

Segment Information

Segment Information [Abstract]
Segment Information	(8) Segment Information  Business Segments  The Drilling Products and Services segment rents and sells premium drill pipe, bottom hole assemblies, 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 and sale of oil and gas and production handling arrangements. The Company evaluates the performance of its reportable segments based on income or loss from operations. The segment measure is calculated as follows: segment revenues less segment operating expenses, depreciation, depletion, amortization and accretion expense, reduction in value of assets and allocated corporate general and administrative expenses. Corporate general and administrative expenses are allocated to the segments based primarily on specific identification and, to the extent that such identification is not practical, other methods that the Company believes to be a reasonable reflection of the utilization of services provided. The Company believes this segment measure is useful in evaluating the performance of its reportable segments because it highlights operating trends and aids analytical comparisons.

Earnings Per Share [Abstract]
Earnings per Share	(11 ) Earnings per Share  Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of common shares 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 common shares that could have been outstanding assuming the exercise of stock options and the conversion of restricted stock units.  For the three and six months ended June 30, 201 7 and 2016 , the Company incurred a loss from continuing operations; therefore the impact of any incremental shares would be anti-dilutive.

Reduction in Value of Assets [Abstract]
Reduction in Value of Assets and Other Charges	( 1 2) Reduction in Value o f Assets  For the six months ended June 30, 2016, the Company recorded $462.5 million in expense related to the reduction in value of assets . The components of the reduction in value of assets are as follows (in thousands):      Reduction in value of goodwill $ 330,500  Reduction in value of long-lived assets 105,859  Retirements of long-lived assets 26,102  Total reduction in value of assets $ 462,461  Reduction in Value of Goodwill  Goodwill is tested for impairment annually 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. T he Company’s goodwill impairment evaluation as of June 30, 2016, indicated that the carrying values of the Onshore Completion and Workover Services and Production Services segments exceeded their fair values so that goodwill was potentially impaired. The Company then performed the second step of the goodwill impairment test, which involved calculating the implied fair value of the segments’ goodwill by allocating the fair values of the Onshore Completion and Workover Services and Production Services segments to all of their assets and liabilities (other than goodwill) and comparing them to the carrying amounts of the goodwill. To estimate the fair value of the reporting unit (which is consistent with the reported business segment), the Company used a weighting of the discounted cash flow method and the public company guideline method of determining fair value of the 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 unit and peer companies’ size, profitability and diversity of operations.  During the six months ended June 30, 2016, the Company recorded a $330.5 million reduction in value of goodwill relating to its Onshore Completion and Workover Services and Production Services segments. The Company determined that the implied fair value of its goodwill for the Onshore Completion and Workover Services segment was less than its carrying value and recorded a $140.0 million impairment of the Onshore Completion and Workover Services segment’s goodwill. In addition, the Company determined that the implied fair value of its goodwill for the Production Services segment was less than its carrying value and recorded a $190.5 million impairment of the Production Services segment’s goodwill.  At June 30, 2017 and December 31, 2016 , the Company’s accumulated reduction in value of goodwill was $1,748.2 million .  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 line of business 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. 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.  During the six months ended June 30, 2016, the Company recorded $105.9 million in connection with the reduction in value of its long-lived assets. The reduction in value of assets was comprised of $2.9 million related to equipment and $45.9 million related to intangibles in the fluid management business in the Onshore Completion and Workover Services segment and $12.4 million related to equipment and $21.0 million related to intangibles, primarily relating to the cementing business in the Production Services segment. In addition, the Company recorded $23.7 million related to the reduction in carrying values of certain accommodation units included in the Drilling Products and Services segment.  Retirements of Long-Lived Assets  During the six months ended June 30, 2016 , the Company recorded $23.9 million in the Drilling Products and Services segment for retirement and abandonment of excess and inoperable and/or functionally obsolete long-lived assets that would require a significant cost to refurbish.

New Accounting Pronouncements
New Accounting Pronouncements	(14 ) 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 condensed consolidated financial statements.  In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation: 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 condensed consolidated financial statements.  In July 2015, the FASB issued ASU No. 2015-11, Inventory – 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 condensed 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 reduce diversity in practice as well as cost and complexity when applying the guidance in Topic 718, Compensation – Stocks 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. The amendments should be applied prospectively to awards modified on or after the adoption date. The Company does not expect the adoption of this ASU to have a material impact on its condensed 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 does not expect the adoption of this ASU to have a material impact on its condensed 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 does not expect the adoption of this ASU to have a material impact on its condensed 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 is evaluating the effect that ASU 2016-16 will have on its condensed consolidated financial statements and related disclosures.  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 condensed 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 new standard is effective for the Company beginning on January 1, 2018. The Company is in the process of determining the impacts the new standard will have on its various revenue streams. The Company’s approach includes performing a detailed review of key contracts representative of the different businesses and comparing historical accounting policies and practices to the new accounting guidance. The Company’s services and rental contracts are primarily short-term in nature, and therefore, based on the initial assessment, the Company does not expect the adoption of this ASU to have a material impact on its condensed consolidated financial statements. Remaining implementation matters include establishing new policies, procedures, and controls and quantifying any adoption date adjustments. The Company will adopt this standard on January 1, 2018 utilizing the modified retrospective method.
