Earnings Per Share [Text Block]

Note 2 – Earnings per Share

The following table presents the reconciliation of the numerator and denominator for calculating earnings per share from continuing operations:

	First Quarter
(In thousands, except per share data)	2016			2015

Basic EPS:
Net income (loss)	$	(13,300	)	$	993

Weighted average number of common shares outstanding		83,258			82,299

Basic income (loss) per common share	$	(0.16	)	$	0.01


Diluted EPS:
Net income (loss)	$	(13,300	)	$	993
Assumed conversions of Senior Notes		-			-
Adjusted net income (loss)	$	(13,300	)	$	993

Weighted average number of common shares outstanding-basic		83,258			82,299
Add: Dilutive effect of stock options and restricted stock awards		-			1,505
Dilutive effect of Senior Notes		-			-
Diluted weighted average number of common shares outstanding		83,258			83,804

Diluted income (loss) per common share	$	(0.16	)	$	0.01

Stock options and restricted stock excluded from calculation of diluted earnings per share because anti-dilutive for the period		6,265			954

For the first quarter of 2016, we excluded 0.6 million shares for the dilutive effect of stock options and restricted stock awards in calculating diluted earnings per share as the effect was anti-dilutive due to the net loss incurred for this period. For the first quarters of 2016 and 2015, we excluded the assumed conversion of the Senior Notes in calculating diluted earnings per share as the effect was anti-dilutive for each period.

Note 3 - Repurchase Program	Mar. 31, 2016
Notes to Financial Statements
Stockholders' Equity Note Disclosure [Text Block]	Note 3 – Repurchase Program In April 2013, our Board of Directors approved a share repurchase program that authorizes the Company to purchase up to $50.0 million of its outstanding shares of common stock. This authorization was subsequently increased to $100.0 million in February 2014. In September 2015, our Board of Directors expanded the repurchase program to include the repurchase of our convertible Senior Notes (as defined in Note 6 below), in addition to outstanding shares of common stock. The repurchase program has no specific term. The Company may repurchase shares or convertible Senior Notes in the open market or as otherwise determined by management, subject to market conditions, business opportunities, limitations under the ABL Facility (as defined in Note 6 below) and other factors. Repurchases are expected to be funded from operating cash flows and available cash on-hand. As part of the share repurchase program, the Company’s management has been authorized to establish trading plans under Rule 10b5-1 of the Securities Exchange Act of 1934. There were no shares repurchased during the first quarter of 2016 or 2015. In February 2016, we repurchased $11.2 million of our convertible Senior Notes in the open market for $9.2 million. This repurchase was made under our existing Board authorized repurchase program discussed above. As of March 31, 2016, we had $33.5 million of authorization remaining under the program.

The entire disclosure for shareholders' equity comprised of portions attributable to the parent entity and noncontrolling interest, including other comprehensive income. Includes, but is not limited to, balances of common stock, preferred stock, additional paid-in capital, other capital and retained earnings, accumulated balance for each classification of other comprehensive income and amount of comprehensive income.

Senior Notes.

In September 2010, we issued $172.5 million of unsecured convertible senior notes (“Senior Notes”) that mature on October 1, 2017, of which, $161.3 million principal amount was outstanding at March 31, 2016. The Senior Notes bear interest at a rate of 4.0% per year, payable semi-annually in arrears on April 1 and October 1 of each year. Holders may convert the Senior Notes at their option at any time prior to the close of business on the business day immediately preceding the October 1, 2017 maturity date. The conversion rate is initially 90.8893 shares of our common stock per $1,000 principal amount of Senior Notes (equivalent to an initial conversion price of $11.00 per share of common stock), subject to adjustment in certain circumstances. Upon conversion, the Senior Notes will be settled in shares of our common stock. We may not redeem the Senior Notes prior to their maturity date. In February 2016, we repurchased $11.2 million of our Senior Notes in the open market for $9.2 million under our existing Board authorized repurchase program and recognized a net gain of $1.9 million in the first quarter of 2016 for the difference in the amount paid and the net carrying value of the extinguished debt, including debt issuance costs.

Revolving Credit Facility.

In March 2015, we entered into a Third Amended and Restated Credit Agreement (the "Credit Agreement") which provided for a $200.0 million revolving loan facility available for borrowings and letters of credit through March 2020. In December 2015, we entered into a First Amendment to the Third Amended and Restated Credit Agreement (“Amendment”) decreasing the revolving credit facility to $150.0 million, modifying certain financial covenants through the first quarter of 2017, and modifying the borrowing cost and fee provisions. The Credit Agreement contained customary financial and operating covenants, including a consolidated leverage ratio, a senior secured leverage ratio and an interest coverage ratio.

At March 31, 2016, we had no outstanding borrowings under the revolving credit facility. Following the significant decline in customer activity during the first quarter of 2016, we were not in compliance with the consolidated leverage ratio and interest coverage ratio covenants included in the Amendment. We terminated the Credit Agreement effective May 12, 2016 and replaced it with an asset-based revolving loan facility as discussed further below. As of the date of termination, we had no outstanding borrowings under the Credit Agreement.

Asset-Based Loan Facility.

On May 12, 2016, we entered into an asset-based revolving credit agreement (the “ABL Facility”) which replaces the terminated Credit Agreement. The ABL Facility provides financing of up to $90.0 million available for borrowings (inclusive of letters of credit), which, subject to the conditions contained therein, can be increased to a maximum capacity of $150.0 million. The ABL Facility terminates on March 6, 2020; however, the ABL Facility has a springing maturity date that will accelerate the maturity of the credit facility to June 30, 2017 if, prior to such date, the Senior Notes have not either been repurchased, redeemed, converted and/or refinanced in full or the Company has not provided sufficient funds to an escrow agent to repay the Senior Notes in full on their maturity date. Borrowing availability under the ABL Facility is calculated based on the level of eligible domestic receivables, inventory, and beginning in 2017, composite mats included in the rental fleet, net of reserves and limits on certain elements of the asset base. Availability associated with eligible rental mats will also be subject to maintaining a minimum consolidated fixed charge coverage ratio and a minimum level of operating income for the Mats and Integrated Services segment, as defined in the ABL Facility agreement. We are unable to borrow funds under the ABL Facility until the satisfaction of the lending conditions, which include the completion of administrative procedures, termination of liens under the Credit Agreement and the securitization of collateral under the ABL Facility, which we anticipate finishing no later than August 1, 2016. If we are unable to complete the process described above prior to August 2, 2016, or obtain an extension of this deadline, the lenders’ commitments under the ABL Facility will terminate.

Under the terms of the ABL Facility, we may elect to borrow at a variable interest rate plus an applicable margin based on either, (1) LIBOR subject to a floor of zero or (2) a base rate equal to the highest of: (a) the federal funds rate plus 50 basis points, (b) the prime rate of Bank of America, N.A. or (c) LIBOR, subject to a floor of zero, plus 100 basis points. The applicable margin ranges from 225 to 350 basis points for LIBOR borrowings, and 125 to 250 basis points with respect to base rate borrowings, based on our consolidated EBITDA, consolidated leverage ratio, and consolidated fixed charge coverage ratio. The initial applicable margin for borrowings under our ABL Facility is 350 basis points with respect to LIBOR borrowings and 250 basis points with respect to base rate borrowings. In addition, we are required to pay a commitment fee on the unused portion of the ABL Facility ranging from 37.5 to 62.5 basis points, based on our consolidated leverage ratio. The initial applicable commitment fee is 62.5 basis points.

The ABL Facility is a senior secured obligation, secured by first liens on all of our U.S. tangible and intangible assets and a portion of the capital stock of our non-U.S. subsidiaries has also been pledged as collateral. The ABL Facility contains customary operating covenants and certain restrictions including, among other things, the incurrence of additional debt, liens, dividends, asset sales, investments, mergers, acquisitions, affiliate transactions, stock repurchases and other restricted payments such as the redemption, defeasance or refinancing of the Senior Notes. In addition, the ABL Facility contains customary events of default, including, without limitation, a failure to make payments under the facility, acceleration of more than $25.0 million of other indebtedness, certain bankruptcy events and certain change of control events.

Other Debt.

Our foreign subsidiaries, primarily those in Italy, Brazil and India, maintain local credit arrangements consisting primarily of lines of credit with several banks, which are renewed on an annual basis. We utilize local financing arrangements in our foreign operations in order to provide short-term local liquidity needs, as well as to reduce the net investment in foreign operations subject to foreign currency risk. Advances under these short-term credit arrangements are typically based on a percentage of the subsidiary’s accounts receivable or firm contracts with certain customers. Total outstanding balances under these arrangements were $5.5 million and $7.4 million at March 31, 2016 and December 31, 2015, respectively.

At March 31, 2016, we had letters of credit issued and outstanding which totaled $14.2 million that are collateralized by $15.5 million in restricted cash. Additionally, our foreign operations had $11.5 million outstanding in letters of credit and other guarantees, with certain letters of credit that are collateralized by $2.0 million in restricted cash. At March 31, 2016, this restricted cash totaling $17.5 million was included in other current assets in the accompanying balance sheet.

Our financial instruments include cash and cash equivalents, receivables, payables and debt. We believe the carrying values of these instruments, with the exception of our Senior Notes, approximated their fair values at March 31, 2016 and December 31, 2015. The estimated fair value of our Senior Notes was $141.5 million at March 31, 2016 and $154.4 million at December 31, 2015, based on quoted market prices at these respective dates.

Note 7 - Commitments and Contingencies	Mar. 31, 2016
Notes to Financial Statements
Commitments and Contingencies Disclosure [Text Block]	Note 7 – Commitments and Contingencies In the ordinary course of conducting our business, we become involved in litigation and other claims from private party actions, as well as judicial and administrative proceedings involving governmental authorities at the federal, state and local levels. Wage and Hour Litigation During the second quarter of 2014, a lawsuit was filed by Jesse Davida, a former employee, in Federal Court in Texas against Newpark Drilling Fluids LLC, alleging violations of the Fair Labor Standards Act (“FLSA”). The plaintiff seeks damages and penalties for the Company’s alleged failure to properly classify its field service employees as “non-exempt” under the FLSA and pay them on an hourly basis (including overtime). The plaintiff seeks recovery on his own behalf, and seeks certification of a class of similarly situated employees. The Court conditionally certified a class of plaintiffs as those working as fluid service technicians for Newpark Drilling Fluids for the prior three years. Notification was given to 658 current and former fluid service technician employees of Newpark regarding this litigation and those individuals were given the opportunity to “opt-in” to the Davida litigation. The opt-in period closed in early May of 2015 and a total of 91 individuals joined the Davida litigation. Counsel for the plaintiffs’ moved to add state law class action claims for current and former fluid service technicians that worked for Newpark Drilling Fluids in New York, North Dakota, Ohio and Pennsylvania. The Court granted the motion but gave Newpark the right to file a motion to dismiss these state law claims, and that motion is pending. At this point in the litigation, the parties began settlement discussions, resulting in the settlement agreement described below. A second case was filed by Josh Christensen in the fourth quarter of 2014 in Federal Court in Texas alleging that individuals treated as independent contractors should have been classified as employees and, as such, are entitled to assert claims for alleged violations of the FLSA (similar to the claims asserted in the Davida matter). Five additional plaintiffs joined this litigation after it was filed. In March of 2015, the Court denied the plaintiffs’ motion for conditional class certification. Counsel for the plaintiffs did not appeal that ruling and have now filed individual cases for each of the original opt-in plaintiffs plus two new plaintiffs, leaving a total of eight independent contractor cases pending. These cases are included in the settlement discussions described below. In the fourth quarter of 2015, the same counsel representing the plaintiffs in the Davida and Christiansen -related cases filed two additional individual FLSA cases on behalf of former fluid service technician employees. These cases are similar in nature to the Davida case discussed above and are included in the settlement discussions described below. Beginning in November 2015, we engaged in settlement discussions with counsel for the plaintiffs in the pending wage and hour litigation cases described above. Following mediation in January of 2016, the parties executed a settlement agreement in April 2016 to settle all of the pending matters, subject to a number of conditions, including approval by the Court in the Davida case, and the dismissal of the other FLSA cases ( Christiansen -related lawsuits and individual FLSA cases). Subject to these conditions, current and former fluid service technician employees that are eligible for the settlement will be notified of the pending resolution and given an opportunity to participate in the settlement. The amount paid to any eligible individual will vary based on a formula that takes into account the number of workweeks and salary for the individual during the time period covered by the settlement (which can vary based upon several factors). Any eligible individual that elects to participate in the settlement will release all wage and hour claims against the Company. As a result of the settlement negotiations, we recognized a $5.0 million charge in the fourth quarter of 2015 related to the pending resolution of these wage and hour litigation claims. We expect to fund the settlement amount with installment payments in the second and third quarters of 2016, subject to the conditions described above. The settlement fund will be administered by a third party who will make payments to eligible individuals that elect to participate in accordance with a formula incorporated into the settlement agreement. In addition, under the terms of the settlement agreement, if settlement funds remain after all payments are made to eligible individuals that elect to participate in the settlement, such excess amount will be shared by the participating individuals and Newpark Drilling Fluids. The amount of excess funds, if any, is not currently determinable. Escrow Claims Related to the Sale of the Environmental Services Business Under the terms of the March 2014 sale of our previous Environmental Services business to Ecoserv, LLC (“Ecoserv”), $8 million of the sales price was withheld and placed in an escrow account to satisfy claims for possible breaches of representations and warranties contained in the sale agreement. For the amount withheld in escrow, $4 million was scheduled for release to Newpark at each of the nine-month and 18-month anniversary of the closing. In December 2014, we received a letter from counsel for Ecoserv asserting that we had breached certain representations and warranties contained in the sale agreement; including failing to disclose service work performed on injection wells and increased barge rental costs. The letter indicated that Ecoserv expected the costs associated with these claims to exceed the escrow amount. Following a further exchange of letters, in July of 2015, we filed a declaratory judgment action against Ecoserv in state court in Harris County, Texas, seeking release of the escrow funds. Thereafter, Ecoserv filed a counterclaim seeking recovery of the escrow funds based on the alleged breach of representations and warranties. Ecoserv also alleges that we committed fraud in connection with the sale transaction. We believe there is no basis in the agreement or on the facts to support the claims asserted by Ecoserv and intend to vigorously defend our position, while pursuing release of the entire $8 million in escrow. The litigation remains in the discovery process.

Operating Income (loss)	$	(18,825	)	$	6,128

In response to the significant declines in industry activity in North America, we initiated cost reduction programs in the first quarter of 2015 including workforce reductions, reduced discretionary spending, and temporary salary freezes for substantially all employees, including executive officers, and have continued these efforts through the first quarter of 2016. In September 2015, we also initiated a voluntary early retirement program with certain eligible employees in the United States for retirement dates ranging from the fourth quarter of 2015 through the third quarter of 2016. As a result of the continuing declines in activity in the first quarter of 2016, we initiated further cost reduction actions including additional workforce reductions and beginning in March 2016, a temporary salary reduction for a significant number of North American employees, including executive officers, suspension of the Company’s matching contribution to the U.S. defined contribution plan as well as a reduction in cash compensation paid to our Board of Directors, in order to further align our cost structure to the current activity levels.

As part of these cost reduction programs, we have eliminated substantially all contract positions and reduced our North American employee base by 591 (approximately 46%) since December 31, 2014, including a 155 employee reduction in the first quarter of 2016. As a result of these termination programs, we recognized charges for employee termination costs of $3.4 million and $2.9 million in the first quarters of 2016 and 2015, respectively, of which $2.7 million and $2.2 million, respectively, are reported in cost of revenues, and $0.7 million and $0.7 million, respectively, are reported in selling, general and administrative expenses. The employee termination costs in the first quarters of 2016 and 2015 include $3.2 million and $2.6 million in Fluids Systems, $0.1 million and $0.2 million in Mats and Integrated Services and $0.1 million and $0.1 million in our corporate office, respectively. Accrued employee termination costs at March 31, 2016 and December 31, 2015 were $1.0 million and $3.3 million, respectively, and are expected to be substantially paid in the first half of 2016.

As discussed above, we revised our estimated useful lives and end of life residual values for composite mats included in our rental fleet resulting in a decrease in depreciation expense of approximately $1.6 million in the first quarter of 2016.

For the first quarter of 2016, revenue from our primary customer in Algeria, Sonatrach, was approximately 15% of consolidated revenues.

The entire disclosure for reporting segments including data and tables. Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.

Significant Accounting Policies (Policies)	3 Months Ended
Significant Accounting Policies (Policies)	Mar. 31, 2016
Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Change in Accounting Estimates During the first quarter of 2016, we reviewed our estimates of the useful lives and residual values of our composite mats rental fleet included in fixed assets for the Mats and Integrated Services segment. We revised our original estimates based on the observed historical service lives and end of life residual values for composite mats. We now estimate that certain composite mats which were originally estimated to have a useful life of 7 years with zero residual value will have estimated useful lives ranging from 10 to 12 years with an estimated residual value of 20%. These changes in estimates were recognized prospectively beginning from January 1, 2016 resulting in a reduction in depreciation expense of approximately $1.6 million for the Mats and Integrated Services segment and additional quarterly net income after taxes of approximately $1.0 million, or $0.01 per share, in the first quarter of 2016. We expect these changes to have a similar effect on future quarterly results in 2016 and going forward.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements Standard adopted in 2016 In September 2015, the Financial Accounting Standards Board (“FASB”) issued updated guidance that eliminates the requirement to restate prior periods to reflect adjustments made to provisional amounts recognized in a business combination. The new guidance requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The new guidance was effective for us prospectively in the first quarter of 2016; however, the adoption did not have any effect on our consolidated financial statements. Standards not yet adopted In May 2014, the FASB amended the existing accounting standards for revenue recognition. The amendments are based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB deferred the effective date of the new guidance by one year and provided entities the option to early adopt the new guidance. The new guidance is effective for us in the first quarter of 2018 with early adoption permitted in the first quarter of 2017. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. We are currently evaluating the impact of these amendments, including the adoption and transition alternatives, on our consolidated financial statements. In July 2015, the FASB issued updated guidance that simplifies the subsequent measurement of inventory. It replaces the current lower of cost or market test with the lower of cost or net realizable value test. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new guidance is effective prospectively for us in the first quarter of 2017 with early adoption permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements. In February 2016, the FASB issued updated guidance regarding accounting for leases. The new accounting standard provides principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to recognize both assets and liabilities arising from financing and operating leases. The classification as either a financing or operating lease will determine whether lease expense is recognized based on an effective interest method basis or on a straight-line basis over the term of the lease, respectively. The new guidance is effective for us in the first quarter of 2019 with early adoption permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements. In March 2016, the FASB issued updated guidance that simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, forfeitures, classification of awards as either equity or liabilities, and classification of excess tax benefits on the statement of cash flows. The new guidance is effective for us in the first quarter of 2017 with early adoption permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements.
