Acquisitions	Jun. 30, 2013
Acquisitions [Abstract]
Acquisitions	(2) Acquisitions Complete Production Services, Inc. On February 7, 2012, the Company acquired Complete Production Services, Inc. (Complete) in a cash and stock merger transaction valued at approximately $2,914.8 million. Complete focused on providing specialized completion and production services and products that help oil and gas companies develop hydrocarbon reserves, reduce costs and enhance production. Complete’s operations were located throughout the U.S. and Mexico. The acquisition of Complete substantially expanded the size and scope of the Company’s services. Complete’s legacy businesses are currently reported in the Onshore Completion and Workover Services and the Production Services segments. Pursuant to the merger agreement, Complete stockholders received 0.945 of a share of the Company’s common stock and $7.00 cash for each share of Complete’s common stock outstanding at the time of the acquisition. In total, the Company paid approximately $553.3 million in cash and issued approximately 74.7 million shares of its common stock valued at approximately $2,308.2 million (based on the closing price of the Company’s common stock on the acquisition date of $30.90). Additionally, the Company paid $676.0 million, inclusive of a $26.0 million prepayment premium, to redeem $650 million of Complete’s 8.0% senior notes. The Company also assumed all outstanding stock options and shares of non-vested and unissued restricted stock held by Complete’s employees and directors at the time of acquisition. Acquisition related expenses totaled approximately $33.3 million, of which approximately $28.8 million was recorded in the six months ended June 30, 2012. The remainder was recorded in the three months ended December 31, 2011. These acquisition related costs include expenses directly related to acquiring Complete and have been recorded in general and administrative expenses in the consolidated statements of income. Other Acquisitions In March 2013, the Company acquired 100% of the equity interest in a company that provides cementing services to oil and gas companies in Colombia. This acquisition provides the Company with a platform for continued expansion in the South American market area. The Company paid approximately $20.4 million at closing and will pay an additional $3.7 million over the next two years, subject to the settlement of certain liabilities. Goodwill of approximately $16.4 million was recognized as a result of this acquisition and was calculated as the excess of the consideration paid over the net assets recognized and represents estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. None of the goodwill related to this acquisition will be deductible for tax purposes. All of the goodwill was assigned to the Production Services segment. In August 2012, the Company acquired 100% of the equity interest in a company that provides mechanical wireline, electric line and well testing services to the oil and gas exploration and production industry in Argentina. The Company paid approximately $37.6 million in cash related to this acquisition, including approximately $6.5 million of contingent consideration paid in April 2013 based upon certain performance metrics.

Inventory and Other Current Assets [Abstract]
Inventory and Other Current Assets	(5) Inventory and Other Current Assets Inventory and other current assets includes approximately $148.8 million and $136.5 million of inventory at June 30, 2013 and December 31, 2012, respectively. The Company’s inventory balance at June 30, 2013 consisted of approximately $65.3 million of finished goods, $9.6 million of work-in-process, $17.9 million of raw materials and $56.0 million of supplies and consumables. The Company’s inventory balance at December 31, 2012 consisted of approximately $63.7 million of finished goods, $6.0 million of work-in-process, $5.0 million of raw materials and $61.8 million of supplies and consumables. Inventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out or weighted-average cost methods for finished goods and work-in-process. Supplies and consumables consist principally of products used in our services provided to customers. On April 17, 2012, SandRidge Energy Inc. (NYSE: SD) (SandRidge) completed its acquisition of Dynamic Offshore Resources, LLC (Dynamic Offshore), at which time the Company received approximately $34.1 million in cash and approximately $51.6 million in shares of SandRidge common stock (approximately 7.0 million shares valued at $7.33 per share) in consideration for its 10% interest in Dynamic Offshore. In accordance with authoritative guidance related to equity securities, the Company is accounting for the shares received in this transaction as available-for-sale securities. The changes in fair values, net of applicable taxes, on available-for-sale securities are recorded as unrealized holding gains (losses) on securities as a component of accumulated other comprehensive loss in stockholders' equity. The fair value of the approximately 1.5 million shares of SandRidge stock held by the Company at June 30, 2013 was approximately $6.9 million. During the six months ended June 30, 2013, the Company recorded an unrealized loss related to the fair value of these securities of $2.3 million, of which $1.4 million was reported within accumulated other comprehensive loss, net of tax expense of $0.9 million. During the six months ended June 30, 2012, the Company recorded an unrealized loss related to the fair value of these securities of $4.5 million, of which $2.8 million was reported within accumulated other comprehensive loss, net of tax expense of $1.7 million. The Company evaluates whether unrealized losses on investments in available-for-sale securities are other-than-temporary, and if it is believed the unrealized losses are other-than-temporary, an impairment charge is recorded. There were no other-than-temporary impairment losses recognized during the six months ended June 30, 2013 and 2012.

Debt	6 Months Ended
Debt	Jun. 30, 2013
Debt [Abstract]
Debt	(6) Debt In May 2013, the Company redeemed the remaining $150 million aggregate principal amount of its 6 7/8% unsecured senior notes due 2014 at 100% of face value using proceeds from that revolving portion its credit facility. The redemption resulted in a loss on early extinguishment of debt of approximately $0.9 million related to the writeoff of debt acquisition costs and note discount. The Company has a $1.0 billion bank credit facility, comprised of a $600 million revolving credit facility and a $400 million term loan. The principal balance of the term loan is payable in installments of $5.0 million on the last day of each fiscal quarter, which began on June 30, 2012. Any amounts outstanding on the revolving credit facility and the term loan are due on February 7, 2017. At June 30, 2013, the Company had $125.0 million outstanding under the revolving portion of its credit facility. The Company also had approximately $56.4 million of letters of credit outstanding, which reduce the Company’s borrowing availability under this portion of the credit facility. Amounts borrowed under the credit facility bear interest at LIBOR plus margins that depend on the Company’s leverage ratio. Indebtedness under the credit facility is secured by substantially all of the Company’s assets, including the pledge of the stock of the Company’s principal domestic subsidiaries. The credit facility contains customary events of default and requires that the Company satisfy various financial covenants. It also limits the Company’s ability to pay dividends or make other distributions, make acquisitions, make changes to the Company’s capital structure, create liens or incur additional indebtedness. At June 30, 2013, the Company was in compliance with all such covenants. The Company has outstanding $500 million of 6 3/8% unsecured senior notes due 2019. The indenture governing the 6 3/8% senior notes requires semi-annual interest payments on May 1^st and November 1^stof each year through the maturity date of May 1, 2019. The indenture contains certain covenants that, among other things, limit the Company from incurring additional debt, repurchasing capital stock, paying dividends or making other distributions, incurring liens, selling assets or entering into certain mergers or acquisitions. At June 30, 2013, the Company was in compliance with all such covenants. The Company also has outstanding $800 million of 7 1/8% unsecured senior notes due 2021. The indenture governing the 7 1/8% senior notes requires semi-annual interest payments on June 15^th and December 15^thof each year through the maturity date of December 15, 2021. The indenture contains certain covenants that, among other things, limit the Company from incurring additional debt, repurchasing capital stock, paying dividends or making other distributions, incurring liens, selling assets or entering into certain mergers or acquisitions. At June 30, 2013, the Company was in compliance with all such covenants.

Earnings Per Share	6 Months Ended
Earnings Per Share	Jun. 30, 2013
Earnings Per Share [Abstract]
Earnings per Share	(7) 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. The weighted average number of common shares outstanding excludes the shares of non-vested restricted stock that were assumed by the Company as a result of the Complete acquisition. 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, conversion of restricted stock units and the vesting of outstanding restricted stock issued in the acquisition of Complete. Stock options for approximately 1,230,000 and 2,090,000 shares of the Company’s common stock for the three months ended June 30, 2013 and 2012, respectively, and approximately 1,200,000 and 1,010,000 shares of the Company’s common stock for the six months ended June 30, 2013 and 2012, were excluded in the computation of diluted earnings per share for these periods as the effect would have been anti-dilutive.

Decommissioning Liabilities

Decommissioning Liabilities [Abstract]

Decommissioning Liabilities

(8) Decommissioning Liabilities

The Company records estimated future decommissioning liabilities in accordance with the authoritative guidance related to asset retirement obligations (decommissioning liabilities), which requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred, with a corresponding increase in the carrying amount of the related long-lived asset. Subsequent to initial measurement, the decommissioning liability is required to be accreted each period to present value.

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 facilities and equipment, and site restoration. Whenever practical, the Company utilizes its own equipment and labor services to perform well abandonment and decommissioning work. When the Company performs these services, all recorded intercompany revenues and related costs of services are eliminated in the condensed consolidated financial statements. The recorded decommissioning liability associated with a specific property is fully extinguished when the property is abandoned. The recorded liability is first reduced by all cash expenses incurred to abandon and decommission the property. If the recorded liability exceeds (or is less than) the Company’s total costs, then the difference is reported as an increase or decrease in revenue during the period in which the work is performed.

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 Company reviews its estimates for the timing of these expenditures on a quarterly basis. As a result of continuing development activities, the Company revised its estimates during the second quarter of 2012 relating to the timing of decommissioning work on Bullwinkle assets, including a 10 year postponement of the platform decommissioning. This change in estimate resulted in a significant reduction in the present value of decommissioning liabilities.

The following table summarizes the activity for the Company’s decommissioning liabilities for the six month periods ended June 30, 2013 and 2012 (in thousands):



	2013	2012

Decommissioning liabilities, December 31, 2012 and 2011, respectively	$ 93,053	$ 123,176

Notes Receivable	6 Months Ended
Notes Receivable	Jun. 30, 2013
Notes Receivable [Abstract]
Notes Receivable	(9) Notes Receivable Notes receivable consist of a commitment from the seller of oil and gas properties acquired by the Company towards the abandonment of the acquired property. 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. During the second quarter of 2012, the Company revised its timing estimate for the Bullwinkle platform removal, resulting in a reduction of the present value of the notes receivable at June 30, 2012 (see note 8). The Company recorded interest income related to notes receivable of $1.5 million and $1.4 million for the six months ended June 30, 2013 and 2012, respectively.

- Definition

The entire disclosure for claims held for amounts due a entity, excluding financing receivables. Examples include, but are not limited to, trade accounts receivables, notes receivables, loans receivables. Includes disclosure for allowance for credit losses.

Segment Information [Abstract]

Segment Information

(10) Segment Information

Business Segments

During the fourth quarter of 2012, the Company revised the internal reporting structure that is used by the chief operating decision maker in determining how to allocate the Company’s resources and, as a result, divided the Subsea and Well Enhancement segment into three segments that better reflect the Company’s product and service offerings throughout the life cycle of a well: Onshore Completion and Workover Services, Production Services, and Subsea and Technical Solutions. The Drilling Products and Services segment remains unchanged. Accordingly, all prior period segment disclosures have been recast to reflect this change in reporting structure.

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 bolting 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. It also provides specialized pressure control tools used to manage and control pressure throughout the life of a well. The Subsea and Technical Solutions segment provides services typically requiring specialized engineering, manufacturing or project planning, including integrated subsea services and engineering services, well control services, 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.

Summarized financial information for the Company’s segments for the three and six months ended June 30, 2013 and 2012 is shown in the following tables (in thousands):

Guarantee	6 Months Ended
Guarantee	Jun. 30, 2013
Guarantee [Abstract]
Guarantee	(11) Guarantee In accordance with authoritative guidance related to guarantees, the Company has assigned an estimated value of $2.6 million at June 30, 2013 and December 31, 2012 related to decommissioning activities in connection with oil and gas properties acquired by the Company’s former subsidiary SPN Resources, LLC (SPN Resources) prior to its sale to Dynamic Offshore in March 2008. The guarantee is reflected in other long-term liabilities. The Company believes that the likelihood of being required to perform these guarantees is remote. In the unlikely event of default on any remaining decommissioning liabilities, the total maximum potential obligation under these guarantees is estimated to be approximately $109.1 million, net of the contractual right to receive payments from third parties, which is approximately $24.6 million, as of June 30, 2013. The total maximum potential obligation will decrease over time as the underlying obligations are fulfilled.

Fair Value Measurements [Abstract]

Fair Value Measurements

(12) Fair Value Measurements

The Company follows the authoritative guidance for fair value measurements relating to financial and nonfinancial assets and liabilities, including presentation of required disclosures herein. This guidance establishes a fair value framework requiring the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets and liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined 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 at June 30, 2013 and December 31, 2012 (in thousands):

Available-for-sale securities is comprised of approximately 1.5 million shares of SandRidge common stock that the Company received as partial consideration for its 10% interest in Dynamic Offshore (see note 5). The securities are reported at fair value based on the stock’s closing price as reported on the New York Stock Exchange.

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 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.

In June 2013 and April 2012, the Company entered into interest rate swap agreements related to its fixed rate debt maturing in 2021 for notional amounts of $100 million each, whereby the Company is entitled to receive semi-annual interest payments at a fixed rate of 7 1/8% per annum and is obligated to make semi-annual interest payments at floating rates, which are adjusted every 90 days, based on LIBOR plus a fixed margin. The swap agreements, scheduled to terminate on December 15, 2021, are designated as fair value hedges of a portion of the Company’s 7 1/8% senior notes, as the derivative has been tested to be highly effective in offsetting changes in the fair value of the underlying note. As these derivatives are classified as fair value hedges, the changes in the fair value of the derivatives are offset against the changes in the fair value of the underlying note in interest expense, net (see note 13). The Company previously had an interest rate swap agreement for a notional amount of $150 million related to its 6 7/8% senior notes that was designated as a fair value hedge. In February 2012, the Company sold this interest rate swap to the counterparty for approximately $1.2 million.

As of June 30, 2013, the Company’s maximum additional consideration payable as a result of prior acquisitions was approximately $3.5 million. The Company has recorded a current liability of approximately $1.6 million, which represents the Company’s estimate of the fair value of the maximum contingent consideration payable. The fair value of the contingent consideration was determined using a probability-weighted discounted cash flow approach at the acquisition and reporting date. The approach is based on significant inputs that are not observable in the market, which are referred to as Level 3 inputs. The fair value is based on the acquired companies reaching specific performance metrics.

During the six months ended June 30, 2013, the Company paid approximately $6.5 million related to its acquisition of a wireline and well testing company in 2012. The following table summarizes the activity recorded using fair value of Level 3 liabilities for the six months ended June 30, 2013 (in thousands):



Balance as of December 31, 2012	$ 9,890
Settlements	(6,500)
Reduction in fair value of liability for
additional consideration	(1,835)

Balance as of June 30, 2013	$ 1,555

In accordance with authoritative guidance, non-financial assets and non-financial liabilities are remeasured at fair value on a non-recurring basis. In determining estimated fair value of acquired goodwill, we use various sources and types of information, including, but not limited to, quoted market prices, replacement cost estimates, accepted valuation techniques such as discounted cash flows, and existing carrying value of acquired assets. As necessary, we utilize third-party appraisal firms to assist us in determining fair value of inventory, identifiable intangible assets, and any other significant assets or liabilities. During the measurement period and as necessary, we adjust the preliminary purchase price allocation if we obtain more information regarding asset valuations and liabilities assumed. During the six months ended June 30, 2013, the Company revised its fair value estimate of contingent consideration payable due to changes in certain performance metrics. The adjustment was recorded in general and administrative expense in the consolidated statement of income.

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 $1,883.5 million and $1,960.0 million at June 30, 2013 and December 31, 2012, 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.

Derivative Financial Instruments

Derivative Financial Instruments [Abstract]

Derivative Financial Instruments

(13) Derivative Financial Instruments

From time to time, the Company may employ interest rate swaps in an attempt to achieve a more balanced debt portfolio. The Company does not use derivative financial instruments for trading or speculative purposes.

In June 2013, the Company entered into an interest rate swap for a notional amount of $100 million related to its 7 1/8% senior notes maturing December 2021. This transaction is designated as a fair value hedge since the swap hedges against the change in fair value of fixed rate debt resulting from changes in interest rates. The Company recorded a derivative asset of $0.2 million within intangible and other long term assets in the consolidated balance sheets at June 30, 2013. The change in fair value of the interest rate swap is included in the adjustments to reconcile net income to net cash provided by operating activities in the consolidated statement of cash flows.

In April 2012, the Company entered into an interest rate swap for a notional amount of $100 million related to its 7 1/8% senior notes maturing in December 2021. This transaction is designated as a fair value hedge since the swap hedges against the change in fair value of fixed rate debt resulting from changes in interest rates. The Company recorded a derivative asset of $0.9 million and $1.3 million within intangible and other long term assets in the consolidated balance sheets at June 30, 2013 and December 31, 2012, respectively. The change in fair value of the interest rate swap is included in the adjustments to reconcile net income to net cash provided by operating activities in the consolidated statement of cash flows.

The Company previously had an interest rate swap agreement for a notional amount of $150 million related to its 6 7/8% senior notes maturing in June 2014 that was designated as a fair value hedge. In February 2012, the Company sold this interest rate swap to the counterparty for approximately $1.2 million.

The location and effect of the derivative instruments on the condensed consolidated statement of operations for the three and six months ended June 30, 2013 and 2012, presented on a pre-tax basis, is as follows (in thousands):



		Three Months Ended June 30, 2013	Three Months Ended June 30, 2012
Interest rate swap	Interest expense, net	$ 7,650	$ (3,156)
Hedged item - debt	Interest expense, net	(7,439)	2,515
		$ 211	$ (641)



		Six Months Ended June 30, 2013	Six Months Ended June 30, 2012

Interest rate swap	Interest expense, net	$ 6,587	$ (3,156)
Hedged item - debt	Interest expense, net	(6,248)	2,515
		$ 339	$ (641)

For the six months ended June 30, 2013 and 2012, approximately $0.3 million of interest expense and $0.6 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.

Subsequent Event

In July 2013, the Company entered into an interest rate swap for a notional amount of $100 million, whereby the Company is entitled to receive semi-annual interest payments at a fixed rate of 7 1/8% per annum and is obligated to make semi-annual interest payments at a variable rate. The variable interest rate, which is adjusted every 90 days, is based on LIBOR plus a fixed margin and is scheduled to terminate on December 15, 2021.

The Company had approximately $26.4 million of unrecorded tax benefits at June 30, 2013 and December 31, 2012, all of which would impact the Company’s effective tax rate if recognized. In addition to its U.S. federal tax return, the Company files income tax returns in various state and foreign jurisdictions.

New Accounting Pronouncements, Policy [Policy Text Block]

(16)	Recently Issued Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board issued ASU 2013-02, “Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (ASU 2013-02). ASU 2013-02 is an update to existing guidance on the presentation of comprehensive income. This update requires companies to report the effect of significant reclassifications out of accumulated other comprehensive income (AOCI) by component. For significant items reclassified out of AOCI to net income in their entirety during the reporting period, companies must report the effect on the line items in the statement where net income is presented. For significant items not reclassified to net income in their entirety during the period, companies must provide cross references in the notes to other disclosures that already provide information about those amounts. The Company adopted this update effective January 1, 2013, and it did not have a material impact on the condensed consolidated financial statements.
