Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncements Recently Adopted On January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments.” The guidance replaces the incurred loss impairment methodology under the current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates referred to as the current expected credit loss (“CECL”) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets ranging from short-term accounts receivables to long-term receivable financing. The Company adopted the standard using the prospective transition approach for its trade receivables and unbilled receivables. The adoption of the standard had no material impact on the Company’s condensed consolidated financial statements. On January 1, 2020, the Company adopted ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” This guidance simplifies the accounting for goodwill impairment by eliminating step 2 from the goodwill impairment test. As a result, an entity should recognize a goodwill impairment charge for the amount by which the reporting unit’s carrying amount exceeds its fair value. If fair value exceeds the carrying amount, no impairment should be recorded. Any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Impairment loss on goodwill cannot be reversed once recognized. The goodwill balance at March 31, 2020 before impairment charge was comprised of $19.5 million in the Optimization Software & Services and $2.9 million in the E&P Technology & Services reporting units. The Company recognized an impairment charge related to the goodwill of its Optimization Software & Service reporting unit, included within Operations Optimization segment, of $4.2 million for the three months ended March 31, 2020. See Note 9 “Details of Selected Balance Sheet Accounts” for details.
