Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements of Nuverra Environmental Solutions, Inc. and its subsidiaries (collectively, “Nuverra,” the “Company,” “we,” “us,” or “our”) are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). Our condensed consolidated balance sheet as of December 31, 2018, included herein, has been derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (or “GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. In our opinion, the condensed consolidated financial statements include the normal, recurring adjustments necessary for the fair statement of the results for the interim periods. These financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, contained in our Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC on March 12, 2019 (the “2018 Annual Report on Form 10-K”). All dollar and share amounts in the footnote tabular presentations are in thousands, except per share amounts and unless otherwise noted. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASC 842”), replacing the previous leasing standard Accounting Standards Codification 840, Leases (“ASC 840”), which requires an entity that is a lessee to recognize the assets and liabilities arising from leases with terms longer than 12 months on the balance sheet. Leases are to be classified as either operating or finance, with classification affecting the pattern of expense recognition in the statement of operations. The new standard was effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. We adopted this new lease standard on January 1, 2019 using a modified retrospective transition, with the cumulative-effect adjustment to the opening balance of accumulated deficit as of the effective date (the “effective date method”). Under the effective date method, financial results reported in periods prior to 2019 are unchanged. We also elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carryforward the historical lease classification. In addition, we have made an accounting policy election to keep leases with an initial term of 12 months or less off of the balance sheet. We will continue to recognize those lease payments in the consolidated statement of operations on a straight-line basis over the lease term. The adoption of the new lease standard resulted in the recognition of operating lease assets and operating lease liabilities of approximately $4.9 million, respectively, as of January 1, 2019. Additionally, as of January 1, 2019, we recorded an adjustment of $0.8 million to accumulated deficit as a result of the re-measurement of the present value of remaining lease payments for the finance leases previously recorded as capital leases. The finance lease assets and finance lease liabilities as of January 1, 2019 were $1.8 million, respectively. We believe the adoption of the new lease standard will not materially impact our results of operations, nor have a notable impact on our liquidity. See Note 3 for further information on our leases. There have been no other material changes or developments in our significant accounting policies or evaluation of accounting estimates and underlying assumptions or methodologies from those disclosed in our 2018 Annual Report on Form 10-K.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASC 842”), replacing the previous leasing standard Accounting Standards Codification 840, Leases (“ASC 840”), which requires an entity that is a lessee to recognize the assets and liabilities arising from leases with terms longer than 12 months on the balance sheet.
