Notes to Financial Statements
Basis of Presentation and Significant Accounting Policies [Text Block]	Note 1 – Basis of Presentation and Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements of Newpark Resources, Inc. and our wholly-owned subsidiaries, which we refer to as “we,” “our” or “us,” have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission (“SEC”), and do not include all information and footnotes required by the accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014. Our fiscal year end is December 31, our second quarter represents the three month period ended June 30 and our first half represents the six month period ending June 30. The results of operations for the second quarter and first half of 2015 are not necessarily indicative of the results to be expected for the entire year. Unless otherwise stated, all currency amounts are stated in U.S. dollars. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary to present fairly our financial position as of June 30, 2015 and the results of our operations for the second quarter and first half of 2015 and 2014, and our cash flows for the first half of 2015 and 2014. All adjustments are of a normal recurring nature. Our balance sheet at December 31, 2014 is derived from the audited consolidated financial statements at that date. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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. For further information, see Note 1 in our Annual Report on Form 10-K for the year ended December 31, 2014. New Accounting Standards In April 2014, the Financial Accounting Standards Board (“FASB”) issued updated guidance that changes the criteria for reporting discontinued operations including enhanced disclosure requirements. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization´s operations and financial results. The new guidance was effective for us in the first quarter of 2015; however, the adoption did not have a material effect on our consolidated financial statements. 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 decided to defer the effective date of the new guidance by one year and allow entities 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 April 2015, the FASB issued updated guidance that changes the presentation of debt issuance costs in financial statements. Under the new guidance, an entity is required to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. The new guidance is effective for us in the first quarter of 2016. Early adoption is permitted. The new guidance will be applied retrospectively to each prior period presented. We are currently evaluating the impact of the new presentation guidance on our consolidated balance sheets.

Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]

Note 2 – Discontinued Operations

In 2013, we initiated a process to sell our Environmental Services business, and in March of 2014 we completed the sale of the business for $100 million in cash, subject to adjustment based on actual working capital conveyed at closing. Cash proceeds from the sale were $89.8 million in 2014, net of transaction related expenses, including the adjustment related to final working capital conveyed at closing. The agreement significantly limits our post-closing environmental obligations, including those related to the waste transfer and disposal facilities. In addition, $8 million of the sales price was withheld in escrow associated with transaction representations, warranties and indemnities, with $4 million scheduled to be released at each of the nine month and 18 month anniversary of the closing. In December 2014, the buyer made certain claims for indemnification under the terms of the agreement, which defers the release of the escrow funds until such claims are resolved. We believe the buyer’s claims are without merit and intend to vigorously pursue resolution. As a result of the sale transaction, we recorded a gain on the disposal of the business of $34.0 million ($22.1 million after-tax) in the first quarter of 2014. The results of operations for this business have been classified as discontinued operations for all periods presented.

Summarized results of operations from discontinued operations are as follows:

	First Half
(In thousands)	2015		2014

Revenues	$	-	$	11,744
Income from discontinued operations before income taxes		-		1,770
Income from discontinued operations, net of tax		-		1,152
Gain from disposal of discontinued operations before income taxes		-		33,974
Gain from disposal of discontinued operations, net of tax		-		22,117

- Definition

The entire disclosure related to a disposal group. Includes, but is not limited to, a discontinued operation, disposal classified as held-for-sale or disposed of by means other than sale or disposal of an individually significant component.

Note 4 – Stock-Based Compensation	Jun. 30, 2015
Notes to Financial Statements
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Note 4 – Stock-Based Compensation During the second quarter of 2015, the Compensation Committee of our Board of Directors approved equity-based compensation to executive officers and other key employees. These awards included a grant of 1,053,937 shares of time-vesting restricted stock units, with vesting periods ranging from three to four years. Non-employee directors received shares of restricted stock totaling 102,218 shares, which will vest in full on the earlier of the day prior to the next annual meeting of stockholders following the grant date or the first anniversary of the grant date. The weighted average fair value on the date of grant for these awards was $9.00 per share. Additionally, 695,698 stock options were granted to executive officers and other key employees at an exercise price of $9.00, which provides for equal vesting over a three-year period with a term of ten years. The estimated fair value of the stock options on the grant date using the Black-Scholes option-pricing model was $3.91. The assumptions used in the Black-Scholes model included a risk free interest rate of 1.57%, expected life of 5.22 years, and expected volatility of 47.3%. The Compensation Committee also approved performance-based awards during the second quarter of 2015 to executive officers. The performance-based restricted stock units will be settled in shares of common stock and will be based on the relative ranking of the Company’s total shareholder return (“TSR”) as compared to the TSR of the Company’s designated peer group for 2015. The performance period began June 1, 2015 and ends May 31, 2018, with the ending TSR price being equal to the average closing price of our shares over the 30-calendar days ending May 31, 2018. A total of 136,882 performance-based restricted stock units were granted with the payout of shares for each executive ranging from 0%-150% of target. The estimated fair value of each restricted stock unit at the date of grant using the Monte Carlo valuation model was $10.06. The valuation was done as of the date of grant, which included a risk free interest rate of 1.02%, the average closing price for our shares over the 30-calendar days ending May 19, 2015 of $8.96 and expected volatility of 38.4%.

Note 5 - Treasury Stock	6 Months Ended
Note 5 - Treasury Stock	Jun. 30, 2015
Notes to Financial Statements
Stockholders' Equity Note Disclosure [Text Block]	Note 5 – Treasury Stock 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. The repurchase program has no specific term. The Company may repurchase shares in the open market or as otherwise determined by management, subject to market conditions, business opportunities and other factors. Repurchases are expected to be funded with a combination of cash generated from operations and borrowings under the Company’s revolving credit facility. 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. During the first half of 2014, 3,875,978 shares were repurchased for an average price of approximately $11.65 per share, including commissions. There were no shares repurchased under the program during the first half of 2015. At June 30, 2015, there was $42.7 million of authorization remaining under the program.

Note 8 - Financing Arrangements and Fair Value of Financial Instruments	6 Months Ended
	Jun. 30, 2015
Notes to Financial Statements
Debt Disclosure [Text Block]	Note 8 – Financing Arrangements and Fair Value of Financial Instruments Our financing arrangements include $172.5 million of unsecured convertible senior notes (“Senior Notes”) and a $200.0 million revolving credit facility which can be increased to a maximum capacity of $325.0 million. At June 30, 2015, we had no outstanding borrowings under the revolving credit facility. Additionally, our foreign operations had $9.2 million outstanding under lines of credit and other borrowings. 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. In 2015, holders converted an insignificant amount of Senior Notes into shares of our common stock. We may not redeem the Senior Notes prior to their maturity date. In March 2015, we entered into a Third Amended and Restated Credit Agreement (the "Credit Agreement") which provides for a $200 million revolving loan facility available for borrowings and letters of credit and expires in March 2020. The Credit Agreement has a springing maturity date that will accelerate the maturity of the credit facility to June 2017 if 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. Under the terms of the Credit Agreement, we can elect to borrow at a variable interest rate either based on LIBOR plus a margin based on our consolidated leverage ratio, ranging from 175 to 275 basis points, or at a variable interest rate based on the greatest of: (a) prime rate, (b) the federal funds rate in effect plus 50 basis points, or (c) the Eurodollar rate for a Eurodollar Loan with a one-month interest period plus 100 basis points, in each case plus a margin ranging from 75 to 175 basis points based on our consolidated leverage ratio. The applicable margins on LIBOR borrowings and Eurodollar borrowings on June 30, 2015 were 100 and 200 basis points, respectively. In addition, we are required to pay a commitment fee on the unused portion of the Credit Agreement of 37.5 basis points. The Credit Agreement contains customary financial and operating covenants, including a consolidated leverage ratio, a senior secured leverage ratio and an interest coverage ratio. The Credit Agreement also limits the payment of dividends on our common stock, the repurchase of our common stock and the conversion, redemption, defeasance or refinancing of the Senior Notes. We were in compliance with these covenants as of June 30, 2015. The Credit Agreement is a senior secured obligation, secured by first liens on all of our U.S. tangible and intangible assets. Additionally, the Credit Agreement is guaranteed by certain of our U.S. subsidiaries and a portion of the capital stock of our non-U.S. subsidiaries has also been pledged as collateral. 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 June 30, 2015 and December 31, 2014. The estimated fair value of our Senior Notes was $181.6 million at June 30, 2015 and $192.3 million at December 31, 2014, based on quoted market prices at these respective dates.

Notes to Financial Statements
Commitments and Contingencies Disclosure [Text Block]	Note 9 – 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. 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 has conditionally certified a class of plaintiffs as those working as fluid service technicians for Newpark Drilling Fluids for the past 3 years. Beginning in early March of 2015, 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 have joined the Davida litigation. The Court has given the plaintiffs’ attorneys until September 2015 to add state law claims to the litigation (if any). The trial of the case has been scheduled for September 2016. 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 plaintiffs plus one new plaintiff, leaving a total of seven independent contractor cases pending. Cases similar to the above have been filed against other companies in the oil and gas services industry, including some of our competitors. In addition, the U.S. Supreme Court is scheduled to consider a case regarding the use of class action procedures in wage and hour litigation ( Tyson Foods, Inc. v. Bouaphakeo ). We are monitoring developments in those matters. Because these cases remain in the early stages, we cannot predict with any degree of certainty the outcome of the litigation at this time and, as a result, cannot estimate any possible loss or range of loss. In the opinion of management, any liability in these matters should not have a material effect on our consolidated financial statements.

In response to the significant declines in industry activity in North America, we initiated cost reduction programs, including workforce reductions, in the first quarter of 2015 and have continued these efforts during the second quarter. Through July 2015, we have reduced our North American employee base by 343 (approximately 26%) since December 31, 2014, in addition to eliminating most contract positions. As a result, we recognized charges for employee termination costs of $0.7 million and $3.6 million in the second quarter and first half of 2015, respectively. For these charges in the second quarter and first half of 2015, $0.3 million and $2.5 million, respectively, are reported in cost of revenues, and $0.4 and $1.1 million, respectively, are reported in selling, general and administrative expenses. The employee termination costs in the second quarter of 2015 include $0.7 million in Fluids Systems. Employee termination costs in the first half of 2015 include $3.3 million in Fluids Systems, $0.2 million in Mats and Integrated Services and $0.1 million in our corporate office. Accrued employee termination costs at June 30, 2015 are $0.4 million and are expected to be substantially paid in the third quarter of 2015.

Significant Accounting Policies (Policies)	6 Months Ended
Significant Accounting Policies (Policies)	Jun. 30, 2015
Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Standards In April 2014, the Financial Accounting Standards Board (“FASB”) issued updated guidance that changes the criteria for reporting discontinued operations including enhanced disclosure requirements. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization´s operations and financial results. The new guidance was effective for us in the first quarter of 2015; however, the adoption did not have a material effect on our consolidated financial statements. 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 decided to defer the effective date of the new guidance by one year and allow entities 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 April 2015, the FASB issued updated guidance that changes the presentation of debt issuance costs in financial statements. Under the new guidance, an entity is required to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. The new guidance is effective for us in the first quarter of 2016. Early adoption is permitted. The new guidance will be applied retrospectively to each prior period presented. We are currently evaluating the impact of the new presentation guidance on our consolidated balance sheets.
