Description of Business [Abstract] | |
Business Description and Basis of Presentation [Text Block] | Core Laboratories N.V. ("Core Laboratories", "we", "our" or "us") is a Netherlands limited liability company. We were established in 1936 and are one of the world's leading providers of proprietary and patented reservoir description and production enhancement services and products to the oil and gas industry. These services and products can enable our clients to improve reservoir performance and increase oil and gas recovery from their producing fields. We have over 70 offices in more than 50 countries and have approximately 4,600 employees. In the first quarter of 2017, Core Laboratories took steps to streamline its business by realigning its reporting structure into two reporting segments. These complementary segments provide different services and products and utilize different technologies for improving reservoir performance and increasing oil and gas recovery from new and existing fields. In connection with the realignment of our reporting structure, amounts previously reported in our Reservoir Management segment are now presented within our Reservoir Description and Production Enhancement segments, and prior periods have been revised to conform to the current presentation. For a description of product types and services offered by these business segments, see Note 18 - |

Accounting Policies [Abstract] | |
Significant Accounting Policies [Text Block] | Principles of Consolidation The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the U.S. ("U.S. GAAP" or "GAAP"), and include the accounts of Core Laboratories and its subsidiaries for which we have a controlling voting interest and/or a controlling financial interest. The equity method of accounting is used to record our interest in investments in which we have less than a majority interest and do not exercise control but do exert significant influence. We use the cost method to record certain other investments in which we own less than 20% of the outstanding equity and do not exercise control or exert significant influence. We record non-controlling interest associated with consolidated subsidiaries that are less than 100% owned. All inter-company transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We evaluate our estimates on an ongoing basis and utilize our historical experience, as well as various other assumptions that we believe are reasonable in a given circumstance, in order to make these estimates. Actual results could differ from our estimates, as assumptions and conditions change. The following accounts, among others, require us to use critical estimates and assumptions: ▪ allowance for doubtful accounts; ▪ obsolete inventory; ▪ depreciation and amortization; ▪ long-lived assets, intangibles and goodwill; ▪ income taxes; ▪ pensions and other postretirement benefits; and ▪ stock-based compensation. Accounting policies relating to these accounts and the nature of these estimates are further discussed under the applicable caption. For each of these critical estimates it is at least reasonably possible that changes in these estimates will occur in the short term which may impact our financial position or results of operations. Cash and Cash Equivalents Cash and cash equivalents include all short-term, highly liquid instruments purchased with an original maturity of three months or less. These items are carried at cost, which approximates fair value. Concentration of Credit Risk Our financial instruments that potentially subject us to concentrations of credit risk relate primarily to cash and cash equivalents and trade accounts receivable. All cash and cash equivalents are on deposit at commercial banks or investment firms with significant financial resources. Our trade receivables are with a variety of domestic, international and national oil and gas companies. We had no clients who provided more than 10% of our revenue for the years ended December 31, 2017 , 2016 and 2015 . We consider our credit risk related to trade accounts receivable to be limited due to the creditworthiness and financial resources of our clients. We evaluate our estimate of the allowance for doubtful accounts on an on-going basis throughout the year. Concentration of Interest Rate Risk We are exposed to interest rate risk on our revolving credit facility (the "Credit Facility") debt, which carries a variable interest rate. We are exposed to interest rate risk on our Senior Notes which carry a fixed interest rate, but whose fair value will fluctuate based on changes in interest rates and market perception of our credit risk. Derivative Instruments We may enter into a variety of derivative instruments in connection with the management of our exposure to fluctuations in interest rates or currency exchange rates. See Note 14 - Derivative Instruments and Hedging Activities . We do not enter into derivatives for speculative purposes. Accounts Receivable Trade accounts receivable are recorded at their invoiced amounts and do not bear interest. We perform ongoing credit evaluations of our clients and monitor collections and payments in order to maintain a provision for estimated uncollectible accounts based on our historical collection experience and our current aging of client receivables outstanding, in addition to client's representations and our understanding of the economic environment in which our clients operate. Based on our review we establish or adjust allowances for specific clients and the accounts receivable as a whole, and recognize expense. When an account is determined to be uncollectible, we charge the receivable to our allowance for doubtful accounts. Our allowance for doubtful accounts totaled $2.6 million and $3.1 million at December 31, 2017 and 2016 , respectively. The net carrying value of accounts receivable is considered to be representative of its respective fair value. Inventories Inventories consist of manufactured goods, materials and supplies used for sales or services to clients. Inventories are stated at the lower of cost or estimated net realizable value. Inventory costs are recorded at standard cost which approximates the first-in, first-out method. Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets are comprised primarily of prepaid insurance, value added taxes and prepaid rents. Property, Plant and Equipment Property, plant and equipment are carried at cost less accumulated depreciation. Major renewals and improvements are capitalized while maintenance and repair costs are charged to expense as incurred. They are depreciated using the straight-line method based on their individual estimated useful lives, except for leasehold improvements, which are depreciated over the remaining lease term, if shorter. We estimate the useful lives and salvage values of our assets based on historical data as follows: Buildings and leasehold improvements 3 - 40 years Machinery and equipment 3 - 10 years When long-lived assets are sold or retired, the remaining costs and related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in income. These capitalized long-lived assets could become impaired if our operating plans or business environment changes. We review our long-lived assets, including definite-lived intangible assets, for impairment when events or changes in circumstances indicate that their net book value may not be recovered over their remaining service lives. Indicators of possible impairment may include significant declines in activity levels in regions where specific assets or groups of assets are located, extended periods of idle use, declining revenue or cash flow or overall changes in general market conditions. Whenever possible impairment is indicated, we compare the carrying value of the assets to the sum of the estimated undiscounted future cash flows expected from use, plus salvage value, less the costs of the subsequent disposition of the assets. If impairment is still indicated, we compare the fair value of the assets to the carrying amount, and recognize an impairment loss for the amount by which the carrying value exceeds the fair value. We did not record any material impairment charges relating to our long-lived assets held for use during the years ended December 31, 2017 , 2016 or 2015 . Intangibles and Goodwill Intangible assets, including patents, trademarks, and trade names, are carried at cost less accumulated amortization. Intangibles with determinable lives are amortized using the straight-line method based on the estimated useful life of the intangible. Intangibles with indeterminable lives, which consist primarily of corporate trade names, are not amortized, but are tested for impairment annually or whenever events or changes in circumstances indicate that impairment is possible. We record goodwill as the excess of the purchase price over the fair value of the net assets acquired in acquisitions accounted for under the purchase method of accounting. We test goodwill for impairment annually, or more frequently if circumstances indicate possible impairment. We evaluated our goodwill for impairment by comparing the fair value of each of our reporting units, which are our reportable segments, to their net carrying value as of the balance sheet date. We estimated the fair value of each reporting unit using a discounted future cash flow analysis. Estimated future cash flows were based on the Company's best estimate of future performance. Our impairment analysis is quantitative; however, it includes subjective estimates based on assumptions regarding future growth rates, interest rates and operating expenses. If the carrying value of the reporting unit exceeds the fair value determined, an impairment loss is recorded to the extent that the implied fair value of the goodwill of the reporting unit is less than its carrying value. Any subsequent impairment loss could result in a material adverse effect upon our financial position and results of operations. We did not record impairment charges relating to our goodwill or our indefinite-lived intangible assets during the years ended December 31, 2017 , 2016 or 2015 . We have never identified nor recorded any impairments relating to the goodwill of our current continuing operations. Other Assets Cash surrender value of life insurance relates to postretirement benefit plans. See Note 10 - Pension and Other Postretirement Benefit Plans . Investments include unconsolidated affiliates accounted for under the equity method where the operations of these entities are in-line with those of our core businesses. These entities are not considered special purpose entities nor do we have special off-balance sheet arrangements through these entities. Other assets consisted of the following (in thousands): 2017 2016 Cash surrender value of life insurance $ 46,314 $ 39,059 Investments in unconsolidated affiliates 3,557 3,224 Other 5,257 4,841 Total other assets $ 55,128 $ 47,124 Accounts Payable Trade accounts payable are recorded at their invoiced amounts and do not bear interest. The carrying value of accounts payable is considered to be representative of its respective fair value. Income Taxes We recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Consolidated Financial Statements or tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statement and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the asset is recovered or the liability is settled. We include interest and penalties from tax judgments in income tax expense. We record a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in our tax return. We also recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense. See Note 9 - Income Taxes . Comprehensive Income Comprehensive income is comprised of net income and other charges or credits to equity that are not the result of transactions with owners. Other comprehensive income consists of prior service costs and an unrecognized net actuarial gain and loss from a pension plan and changes in the fair value of our interest rate swaps. See Note 10 - Pension and Other Postretirement Benefit Plans and Note 14 - Derivative Instruments and Hedging Activities . Revenue Recognition We recognize revenue when we determine that the following criteria are met: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed or determinable; and (iv) collectability is reasonably assured. Services Revenue : We provide a variety of services to clients in the oil and gas industry. Where services are provided related to the testing and analysis of rock and fluids, we recognize revenue upon the provision of the test results or analysis to the client. For our design, field engineering and completion diagnostic services, we recognize revenue upon the delivery of those services at the well site. In the case of our consortium studies, revenue is recognized when the reservoir model solution is presented to our clients. We conduct testing and provide analysis services in support of our consortium studies recognizing revenue as the testing and analysis results are made available to our consortium members. Product Sales Revenue : We manufacture equipment that we sell to our clients in the oil and gas well industry. Revenue is recognized when title to that equipment passes to the client, which is typically when the product is shipped to the client or picked up by the client at our facilities, as set out in the contract. All advance client payments are classified as unearned revenue until services are performed or product title is transferred. Foreign Currencies Our functional currency is the U.S. Dollar ("USD"). All inter-company financing, transactions and cash flows of our subsidiaries are transacted in USD. Our foreign entities remeasure monetary assets and liabilities to USD at year-end exchange rates, while non-monetary items are measured at historical rates. Revenue and expenses are remeasured at the applicable month-end rate, except for depreciation, amortization and certain components of cost of sales, which are measured at historical rates. For the years ended December 31, 2017 , 2016 and 2015 , we incurred net remeasurement loss es of $0.9 million , $1.8 million , and $4.5 million , respectively. These amounts were included in Other (Income) Expense, net in the accompanying Consolidated Statements of Operations. Pensions and Other Postretirement Benefits We provide a non-contributory defined benefit pension plan covering substantially all of our Dutch employees ("Dutch Plan") who were hired prior to 2007. As required by current accounting standards, we recognize net periodic pension costs associated with the Dutch plan in income from current operations and recognize the unfunded status of the plan, if any, as a long-term liability. In addition, we recognize as a component of other comprehensive income, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic pension cost. The projection of benefit obligation and fair value of plan assets requires the use of assumptions and estimates. Actual results could differ from those estimates. See Note 10 - Pension and Other Postretirement Benefit Plans . Furthermore, we maintain defined contribution plans for the benefit of eligible employees primarily in Canada, the Netherlands, the United Kingdom and the United States. We expense these contributions in the period the contribution is made. Non-controlling Interests We maintain non-controlling interests in several investment ventures and disclose such interests clearly as a portion of equity separate from the parent's equity. The amount of consolidated net income attributable to these non-controlling interests must also be clearly presented on the Consolidated Statements of Operations. In addition, when a subsidiary is deconsolidated, any retained non-controlling equity investment in the former subsidiary will be initially measured at fair value and recorded as a gain or loss. Stock-Based Compensation We have two stock-based compensation plans, as described in further detail in Note 13 - Stock-Based Compensation . For new awards issued and awards modified, repurchased or canceled, the compensation expense is equal to the fair value of the award at the date of the grant and is recognized in the Consolidated Statements of Operations for those awards earned over the requisite service period of the award. Earnings Per Share We compute basic earnings per common share by dividing net income attributable to Core Laboratories N.V. by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common share include additional shares in the weighted average share calculations associated with the incremental effect of dilutive restricted stock awards and contingently issuable shares, as determined using the treasury stock method. The following table summarizes the calculation of weighted average common shares outstanding used in the computation of diluted earnings per share (in thousands): For the Years Ended December 31, 2017 2016 2015 Weighted average basic common shares outstanding 44,153 43,479 42,747 Effect of dilutive securities: Performance shares 69 127 98 Restricted stock 42 64 63 Weighted average diluted common and potential common shares outstanding 44,264 43,670 42,908 |

Acquisitions [Abstract] | |
Business Combination Disclosure [Text Block] | We had no significant acquisitions during the year ended December 31, 2017 and 2016. In 2015, we acquired a business providing additional reservoir fluids technology which was accounted for by allocating the purchase price to the net assets acquired based on their estimated fair values at the date of acquisition. The acquisition of this entity did not have a material impact on our Consolidated Balance Sheets or Consolidated Statements of Operations, and was recorded in the Reservoir Description business segment. |

Debt [Abstract] | |
Debt and Capital Leases Disclosures [Text Block] | We have no capital lease obligations. Debt at December 31, 2017 and 2016 is summarized in the following table (in thousands): December 31, 2017 December 31, 2016 Senior Notes $ 150,000 $ 150,000 Credit Facility 78,000 68,000 Total debt 228,000 218,000 Less: Debt issuance costs (1,011 ) (1,512 ) Long-term debt, net $ 226,989 $ 216,488 In 2011, we issued two series of senior notes with an aggregate principal amount of $150 million ("Senior Notes") in a private placement transaction. Series A consists of $75 million in aggregate principal amount of notes that bear interest at a fixed rate of 4.01% and are due in full on September 30, 2021 . Series B consists of $75 million in aggregate principal amount of notes that bear interest at a fixed rate of 4.11% and are due in full on September 30, 2023 . Interest on each series of the Senior Notes is payable semi-annually on March 30 and September 30. The terms of our Credit Facility allow an aggregate borrowing capacity of $400 million and to increase the uncommitted availability by an additional $ 50 million to bring the total borrowings available from $400 million to $450 million if certain prescribed conditions are met by the Company. The Credit Facility bears interest at variable rates from LIBOR plus 1.25% to a maximum of LIBOR plus 2.0% . Any outstanding balance under the Credit Facility is due August 29, 2019 , when the Credit Facility matures. Interest payment terms are variable depending upon the specific type of borrowing under this facility. Our available capacity at any point in time is subject to all terms of the agreements, and is reduced by borrowings outstanding at the time and outstanding letters of credit which totaled $14.3 million at December 31, 2017 , resulting in an available borrowing capacity under the Credit Facility of $307.7 million . In addition to those items under the Credit Facility, we had $14.0 million of outstanding letters of credit and performance guarantees and bonds from other sources as of December 31, 2017 . The terms of the Credit Facility and Senior Notes require us to meet certain covenants, including, but not limited to, an interest coverage ratio (consolidated EBITDA divided by interest expense) and a leverage ratio (consolidated net indebtedness divided by consolidated EBITDA), where consolidated EBITDA (as defined in each agreement) and interest expense are calculated using the most recent four fiscal quarters. The Credit Facility has the more restrictive covenants with a minimum interest coverage ratio of 3.0 to 1.0 and a maximum leverage ratio of 2.5 to 1.0. We believe that we are in compliance with all such covenants contained in our credit agreements. Certain of our material, wholly-owned subsidiaries are guarantors or co-borrowers under the Credit Facility and Senior Notes. In 2014, we entered into two interest rate swap agreements to hedge changes in the variable interest rate on our LIBOR-priced debt. See Note 14 - Derivative Instruments and Hedging Activities for discussion of our derivative instruments. The estimated fair value of total debt at December 31, 2017 and 2016 approximated the book value of total debt. The fair value was estimated using Level 2 inputs by calculating the sum of the discounted future interest and principal payments through the date of maturity. |

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 was signed into law reducing the U.S. corporate income tax rate to 21% effective January 1, 2018. We recorded a $1.6 million non-cash discrete tax charge in the fourth quarter of 2017, primarily as a result of revaluing deferred tax positions for the net impact of the reduction in tax rate. We are continuing our analysis of the effects this tax reform will have on the Company in future periods. We have not provided for deferred taxes on the unremitted earnings of certain subsidiaries that we consider to be indefinitely reinvested. Should we make a distribution of the unremitted earnings of these subsidiaries, we may be required to record additional taxes. As of December 31, 2017 , we consider $246.0 million to be indefinitely reinvested. Repatriation of these earnings would be subject to income and withholding taxes estimated at $25.3 million . There are no restrictions preventing any of our subsidiaries from repatriating earnings, and there are no restrictions or income taxes associated with distributing cash to the parent company through loans or advances. At December 31, 2017 , we had tax net operating loss carry-forwards in various tax jurisdictions of $32.7 million . Although we cannot be certain that these operating loss carry-forwards will be utilized, we anticipate that we will have sufficient taxable income in future years to allow us to fully utilize the carry-forwards that are not subject to a valuation allowance. As of December 31, 2017 , if unused, $3.0 million will expire between 2018-2020 , $3.9 million will expire between 2021-2023 , $17.5 million will expire between 2024-2027 and $1.0 million will expire beyond 2027 . The remaining balance of $7.3 million is not subject to expiration. During 2017 , $1.1 million of net operating loss carry-forwards, which carried a full valuation allowance, expired unused. We file income tax returns in the U.S. federal jurisdiction, various states and foreign jurisdictions. We are currently undergoing multiple examinations in various jurisdictions, and the years 2000 through 2016 remain open for examination in various tax jurisdictions in which we operate. The ultimate settlement and timing of these additional tax assessments is uncertain but the Company will continue to vigorously defend its return filing position and does not view the assessments as probable at this time. During 2017 , adjustments were made to estimates for uncertain tax positions in certain tax jurisdictions based upon changes in facts and circumstances, resulting in a reduction to the unrecognized tax benefits. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): 2017 2016 2015 Unrecognized tax benefits at January 1, $ 8,557 $ 9,964 $ 11,747 Tax positions, current period 3,472 983 1,044 Tax positions, prior period 180 83 (640 ) Settlements with taxing authorities (1,154 ) (1,657 ) (1,371 ) Lapse of applicable statute of limitations (931 ) (816 ) (816 ) Unrecognized tax benefits at December 31, $ 10,124 $ 8,557 $ 9,964 Changes in our estimate of, or the recognition of, the unrecognized tax benefits shown in the table above would affect our effective tax rate. Our policy is to record accrued interest and penalties on uncertain tax positions, net of any tax effect, as part of total tax expense for the period. The corresponding liability is carried along with the tax exposure as a non-current payable in Other Long-term Liabilities. For the years ended December 31, 2017 , 2016 and 2015 , we recognized $0.6 million , $0.6 million and $(0.5) million , respectively, in interest and penalties. For the years ended December 31, 2017 , 2016 and 2015 , we had $3.3 million , $2.7 million and $2.0 million , respectively, accrued for the payment of interest and penalties. Changes in our estimate of unrecognized tax benefits would affect our effective tax rate. As of December 31, 2017, 2016, and 2015, there are $1.8 million , 1.2 million and $2.4 million , respectively, of unrecognized tax benefits that could be resolved within the next twelve months which could have a positive effect on the annual effective tax rate. |

Pension and Other Postretirement Benefit Plans [Abstract] | |
Pension and Other Postretirement Benefits Disclosure [Text Block] | Defined Benefit Plan We provide a noncontributory defined benefit pension plan covering substantially all of our Dutch employees ("Dutch Plan") who were hired prior to 2007. This pension benefit is based on years of service and final pay or career average pay, depending on when the employee began participating. The benefits earned by the employees are immediately vested. We fund the future obligations of the Dutch Plan by purchasing insurance contracts from a large multi-national insurance company. The insurance contracts have a five -year maturity. Each year, as a contract expires, it is replaced with a new contract that is adjusted to include changes in the benefit obligation for the current year and redemption of the expired contract. We make annual premium payments to the insurance company based on each employee's age and current salary, and the contractual growth rate. We determine the fair value of these plan assets with the assistance of an actuary using observable inputs (Level 2), which approximates the contract value of the investments. The following table summarizes the change in the projected benefit obligation and the fair value of plan assets for the Dutch Plan for the years ended December 31, 2017 and 2016 (in thousands): 2017 2016 Projected Benefit Obligation: Projected benefit obligation at beginning of year $ 56,082 $ 50,759 Service cost 1,494 1,456 Interest cost 1,121 1,329 Benefits paid (1,212 ) (1,139 ) Administrative expenses (35 ) (31 ) Actuarial (gain) loss, net (1,005 ) 5,225 Unrealized (gain) loss on foreign exchange 6,953 (1,517 ) Projected benefit obligation at end of year $ 63,398 $ 56,082 Fair Value of Plan Assets: Fair value of plan assets at beginning of year $ 46,134 $ 41,116 Increase in plan asset value 919 6,328 Employer contributions 1,595 1,118 Benefits paid (1,212 ) (1,139 ) Administrative expenses (35 ) (31 ) Unrealized gain (loss) on foreign exchange 5,744 (1,258 ) Fair value of plan assets at end of year $ 53,145 $ 46,134 Under-funded status of the plan at end of the year $ (10,253 ) $ (9,948 ) Accumulated Benefit Obligation $ 56,035 $ 47,980 The following actuarial assumptions were used to determine the actuarial present value of our projected benefit obligation and the net periodic pension costs for the Dutch Plan at December 31, 2017 and 2016 : 2017 2016 Weighted average assumed discount rate 2.00% 1.90% Expected long-term rate of return on plan assets 2.00% 1.90% Weighted average rate of compensation increase 2.90% 2.75% The discount rate used to determine our projected benefit obligation at December 31, 2017 was increased from 1.90% to 2.00% , consistent with a general increase in interest rates in Europe for AAA-rated long-term Euro government bonds. Amounts recognized for the Dutch Plan in the Consolidated Balance Sheets for the years ended December 31, 2017 and 2016 consist of (in thousands): 2017 2016 Deferred tax asset $ 2,564 $ 2,328 Other long-term liabilities 10,253 9,948 Accumulated other comprehensive loss (8,162 ) (9,169 ) The components of net periodic pension cost for the Dutch Plan under this plan for the years ended December 31, 2017 , 2016 , and 2015 included (in thousands): 2017 2016 2015 Service cost $ 1,494 $ 1,456 $ 1,787 Interest cost 1,121 1,329 1,192 Expected return on plan assets (950 ) (1,117 ) (986 ) Unrecognized pension asset, net — — (96 ) Prior service cost (77 ) (81 ) (85 ) Unrecognized net actuarial loss 440 593 727 Net periodic pension cost $ 2,028 $ 2,180 $ 2,539 Plan assets at December 31, 2017 and 2016 consisted of insurance contracts with returns equal to the contractual rate, which are comparable with governmental debt securities. Our expected long-term rate of return assumptions are based on the weighted-average contractual rates for each contract. Dutch law dictates the minimum requirements for pension funding. Our goal is to meet these minimum funding requirements, while our insurance carrier invests to minimize risks associated with future benefit payments. Our 2018 minimum funding requirements are expected to be $1.4 million . Our estimate of future annual contributions is based on current funding requirements, and we believe these contributions will be sufficient to fund the plan. Expected benefit payments to eligible participants under this plan for the next five years are as follows (in thousands): 2018 $ 1,362 2019 $ 1,419 2020 $ 1,507 2021 $ 1,572 2022 $ 1,691 Succeeding five years $ 9,808 Defined Contribution Plans We maintain defined contribution plans for the benefit of eligible employees primarily in Canada, the Netherlands, the United Kingdom, and the United States. In accordance with the terms of each plan, we and our participating employees contribute up to specified limits and under certain plans, we may make discretionary contributions in accordance with the defined contribution plans. Our primary obligation under these defined contribution plans is limited to paying the annual contributions. For the years ended December 31, 2017 , 2016 and 2015 , we paid $4.2 million , $6.1 million and $6.9 million , respectively, for our contributions and our additional discretionary contributions to the defined contribution plans. Vesting in all employer contributions is accelerated upon the death of the participant or a change in control. Employer contributions under the plans are forfeited upon a participant’s termination of employment to the extent they are not vested at that time. Deferred Compensation Arrangements We have entered into deferred compensation contracts for certain key employees to provide additional retirement income to the participants. The benefit is determined by the contract for either a fixed amount or by a calculation using years of service or age at retirement along with the average of their base salary for the five years prior to retirement. We are not required to fund this arrangement; however, we have purchased life insurance policies with cash surrender values to assist us in providing the benefits pursuant to these deferred compensation contracts with the actual benefit payments made by Core Laboratories. The charge to expense for these deferred compensation contracts in 2017 , 2016 and 2015 was $1.4 million , $1.2 million and $1.7 million , respectively. We provide severance compensation to certain current key employees if employment is terminated under certain circumstances, such as following a change in control or for any reason other than upon their death or disability, for “cause” or upon a material breach of a material provision of their employment agreement, as defined in their employment agreements. In addition, there are certain countries where we are legally required to make severance payments to employees when they leave our service. We have accrued for all of these severance payments, but they are not funded. We have also adopted a non-qualified deferred compensation plan (“Deferred Compensation Plan”) that allows certain highly compensated employees to defer a portion of their salary, commission and bonus, as well as the amount of any reductions in their deferrals under the Deferred Compensation Plan for employees in the United States, due to certain limitations imposed by the U.S. Internal Revenue Code of 1986, as amended (the “Code”). Contributions to the plan are invested in equity and other investment fund assets, and carried on the balance sheet at fair value. The benefits under these contracts are fully vested. Our primary obligation for the Deferred Compensation Plan is limited to our annual contributions. Employer contributions to the Deferred Compensation Plan for the years ended December 31, 2017 , 2016 and 2015 were $0.1 million , $0.2 million , and $0.3 million , respectively. Vesting in all employer contributions is accelerated upon the death of the participant or a change in control. Employer contributions under the plans are forfeited upon a participant's termination of employment to the extent they are not vested at that time. |

COMMITMENTS AND CONTINGENCIES [Abstract] | |
Commitments and Contingencies Disclosure [Text Block] | We have been and may from time to time be named as a defendant in legal actions that arise in the ordinary course of business. These include, but are not limited to, employment-related claims and contractual disputes or claims for personal injury or property damage which occur in connection with the provision of our services and products. A liability is accrued when a loss is both probable and can be reasonably estimated. During 2015, we recorded contingent liabilities in the amount of $8.6 million associated with these claims. After certain settlements in 2016, we had a contingent liability balance of $5.3 million remaining as of December 31, 2017. In 1998, we entered into employment agreements with our three senior executive officers that provide for deferred compensation benefits. The present value of the long-term liability recorded and fully reserved for the benefits due upon severing the employment of these employees is $8.5 million at December 31, 2017 . We do not maintain any off-balance sheet debt or other similar financing arrangements nor have we formed any special purpose entities for the purpose of maintaining off-balance sheet debt.

Stockholders' Equity Note Disclosure [Text Block] | Common Shares In 2016, we completed a public offering of 1,475,000 shares of our common stock. The purchase price paid by the underwriter was $116.67 per share. The underwriter exercised in full its option to purchase an additional 221,250 shares of common stock at the public offering price of $116.67 per share bringing the total shares issued from the offering to 1,696,250 . The net proceeds from these issuances of common stock were $197.2 million , after deducting underwriting discounts and offering expenses. The proceeds were used to repay a portion of the outstanding borrowings under our Credit Facility.

This authorization was renewed at subsequent annual or special shareholder meetings. At our annual shareholders' meeting on May 18, 2017 , our shareholders authorized an extension to repurchase up to 10% of our issued share capital through November 18, 2018 . The repurchase of shares in the open market is at the discretion of management pursuant to this shareholder authorization. From the activation of the share repurchase program on October 29, 2002 through December 31, 2017 , pursuant to shareholder approvals, we have repurchased 39,532,314 shares for an aggregate purchase price of approximately $1.6 billion , or an average price of $41.45 per share and have canceled 33,475,406 shares with an historical cost of $1.2 billion .

Stock-based Compensation [Abstract] | |
Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | We have granted restricted stock awards under two stock incentive plans: the 2014 Long-Term Incentive Plan and the 2014 Nonemployee Director Stock Incentive Plan. Awards under the following two compensation programs have been granted pursuant to both plans: (1) the Performance Share Award Program ("PSAP") and (2) the Restricted Share Award Program ("RSAP") and the Restricted Share Award Program for Nonemployee Directors (the "Program"). We issue shares from either treasury stock or authorized shares upon the lapsing of vesting restrictions on restricted stock. In 2017 , we issued 191,513 shares out of treasury stock relating to the vesting of restricted stock. We do not use cash to settle equity instruments issued under stock-based compensation awards. 2014 Long-Term Incentive Plan On May 13, 2014, the 2007 Long-Term Incentive Plan was amended, restated and renamed as the 2014 Long-Term Incentive Plan (the "Plan"). The primary changes effected by the 2014 amendment and restatement were to (a) extend the period during which awards may be granted under the Plan to May 12, 2024, and (b) increase the number of common shares subject to the Plan by 1,100,000 shares. The Plan, as amended, provides for a maximum of 11,900,000 common shares to be granted to eligible employees. At December 31, 2017 , approximately 1,106,157 shares remained available for the grant of new awards under the Plan. Specifically, we encourage share ownership by awarding various long-term equity incentive awards under the Plan, consisting of the PSAP and RSAP. We believe that widespread common share ownership by key employees is an important means of encouraging superior performance and employee retention. Additionally, our equity-based compensation programs encourage performance and retention by providing additional incentives for executives to further our growth, development and financial success over a longer time horizon by personally benefiting through the ownership of our common shares and/or rights. Performance Share Award Program On February 10, 2015, certain executives were awarded rights to receive an aggregate of up to 106,455 common shares if our calculated return on invested capital ("ROIC"), as defined in the PSAP, achieves certain performance criteria as compared to the Bloomberg Comp Group at the end of the performance period, which ends on the last trading day of 2017, December 29, 2017. Unless there is a change in control as defined in the PSAP, none of these awards will vest if the specified performance target is not met as of the last day of the performance period. This arrangement is recorded as an equity award that requires us to recognize compensation expense totaling $11.3 million over the performance period that began on January 1, 2015, of which $3.8 million has been recognized annually in 2017, 2016, and 2015. At December 29, 2017, the Company had the highest ROIC compared to the Bloomberg Comp Group. The Compensation Committee of our Board of Supervisory Directors verified that the performance target criteria had been met and 106,455 shares vested. We issued these common shares on December 29, 2017 and, simultaneously, the participants surrendered 37,534 common shares to settle any personal tax liabilities which may result from the award, as permitted by the agreement. We recorded these surrendered shares as treasury stock with an aggregate cost of $4.1 million at $ 109.55 per share. On February 16, 2016, certain executives were awarded rights to receive an aggregate of up to 122,515 common shares if our calculated ROIC, as defined in the PSAP, achieves certain performance criteria as compared to the Bloomberg Comp Group at the end of the performance period, which ends on the last trading day of 2018, December 31, 2018. Unless there is a change in control as defined in the PSAP, none of these awards will vest if the specified performance target is not met as of the last day of the performance period. This arrangement is recorded as an equity award that requires us to recognize compensation expense totaling $11.4 million over the performance period that began on January 1, 2016, of which $3.9 million has been recognized annually in 2017 and 2016. The unrecognized compensation expense is expected to be recognized over an estimated amortization period of 12 months. On February 14, 2017, certain executives were awarded rights to receive an aggregate of up to 128,112 common shares if our calculated ROIC, as defined in the PSAP, achieves certain performance criteria as compared to the Bloomberg Comp Group at the end of the performance period, which ends on the last trading day of 2019, December 31, 2019. Unless there is a change in control as defined in the PSAP, none of these awards will vest if the specified performance target is not met as of the last day of the performance period. This arrangement is recorded as an equity award that requires us to recognize compensation expense totaling $14.2 million over the performance period that began on January 1, 2017, of which $4.7 million has been recognized in 2017. The unrecognized compensation expense is expected to be recognized over an estimated amortization period of 24 months. Restricted Share Award Program In 2004, the Compensation Committee of our Board of Supervisory Directors approved the RSAP to attract and retain the best employees, and to better align employee interests with those of our shareholders. Under this arrangement we awarded grants totaling 101,811 shares, 104,164 shares, and 91,784 shares in 2017 , 2016 , and 2015 , respectively. Each of these grants has a vesting period of principally six years and vests ratably on an annual basis. There are no performance accelerators for early vesting for these awards. Awards under the RSAP are classified as equity awards and recorded at the grant-date fair value with the compensation expense recognized over the expected life of the award. As of December 31, 2017 , there was $26.4 million of unrecognized total stock-based compensation relating to non-vested RSAP awards. The unrecognized compensation expense is expected to be recognized over an estimated weighted-average amortization period of 42 months. The grant-date fair value of shares granted was $9.5 million , $10.0 million and $8.9 million in 2017 , 2016 and 2015 , respectively. We recognized compensation expense of $9.0 million , $10.5 million and $10.4 million in 2017 , 2016 and 2015 , respectively. The total grant-date fair value, which is the intrinsic value, of the shares vested was $9.6 million , $9.9 million and $10.4 million in 2017 , 2016 and 2015 , respectively. 2014 Nonemployee Director Stock Incentive Plan On May 13, 2014, the 2006 Nonemployee Director Stock Option Plan was amended, restated and renamed as the 2014 Nonemployee Director Stock Incentive Plan (the "Director Plan"). The primary change effected by the 2014 amendment was to extend the period during which awards may be granted under the Director Plan to May 12, 2024. The Director Plan provides common shares for grant to our eligible Supervisory Directors. The maximum number of shares available for award under this plan is 1,400,000 common shares. As of December 31, 2017 approximately 543,159 shares remained available for issuance under the Director Plan. Only non-employee Supervisory Directors are eligible for these equity-based awards under the Director Plan. In 2011, the Compensation Committee of our Board of Supervisory Directors approved the restricted share award program (the "Program") to compensate our non-employee Supervisory Directors. Under this arrangement we awarded grants totaling 9,093 shares, 10,680 shares and 8,616 shares in 2017 , 2016 , and 2015 , respectively. The shares awarded in 2017 have a vesting period of one year; the shares awarded in 2016 and 2015 have a vesting period of three years for each grant. There are no performance accelerators for early vesting for these awards. Awards under the Program are classified as equity awards and recorded at the grant-date fair value with compensation expense recognized over the expected life of the award. As of December 31, 2017 , there was $0.8 million of unrecognized total stock-based compensation relating to non-vested Program awards. The unrecognized compensation expense is expected to be recognized over an estimated weighted-average amortization period of 10 months. The grant-date fair value of shares granted was $1.0 million , $1.1 million and $0.9 million in 2017 , 2016 , and 2015 , respectively, and we have recognized compensation expense of $1.5 million , $0.9 million and $0.9 million in 2017 , 2016 , and 2015 , respectively. Stock-based Compensation Non-vested restricted share awards outstanding under both the Plan and the Director Plan as of December 31, 2017 and changes during the year were as follows: Number of Shares Weighted Average Grant Date Fair Value per Share Non-vested at December 31, 2016 545,614 $ 110.11 Granted 203,512 101.97 Vested (191,022 ) 114.11 Forfeited (21,354 ) 114.89 Non-vested at December 31, 2017 536,750 $ 105.42 For the years ended December 31, 2017 , 2016 and 2015 , stock-based compensation expense under both the Plan and the Director Plan recognized in the income statement is as follows (in thousands): 2017 2016 2015 Cost of product sales and services $ 8,879 $ 10,073 $ 10,126 General and administrative 14,063 12,006 11,153 Total stock-based compensation expense $ 22,942 $ 22,079 $ 21,279 |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Instruments and Hedging Activities Disclosure [Text Block] | We are exposed to market risks related to fluctuations in interest rates. To mitigate these risks, we utilize derivative instruments in the form of interest rate swaps. We do not enter into derivative transactions for speculative purposes. Interest Rate Risk Series A of our Senior Notes bears interest at a fixed rate of 4.01% and Series B bears interest at a fixed rate of 4.11% . Our Credit Facility bears interest at variable rates from LIBOR plus 1.25% to a maximum of LIBOR plus 2.00% . We are subject to interest rate risk on the debt in excess of $50 million drawn on our Credit Facility. In 2014, we entered into two interest rate swap agreements for a total notional amount of $50 million to hedge changes in the variable rate interest expense on $50 million of our existing or replacement LIBOR-priced debt. Under the first swap agreement of $25 million , we have fixed the LIBOR portion of the interest rate at 1.73% through August 29, 2019 , and under the second swap agreement of $25 million , we have fixed the LIBOR portion of the interest rate at 2.50% through August 29, 2024 . Each swap is measured at fair value and recorded in our consolidated balance sheet as a liability. They are designated and qualify as cash flow hedging instruments and are highly effective. Unrealized losses are deferred to shareholders' equity as a component of accumulated other comprehensive loss and are recognized in income as an increase to interest expense in the period in which the related cash flows being hedged are recognized in expense. At December 31, 2017 , we had fixed rate debt aggregating $200 million and variable rate debt aggregating $28 million , after taking into account the effect of the swaps.

Fair Value Disclosures [Text Block] | The Company's only financial assets and liabilities which are measured at fair value on a recurring basis relate to certain aspects of the Company's benefit plans and our derivative instruments. We use the market approach to value certain assets and liabilities at fair value using significant other observable inputs (Level 2) with the assistance of a third party specialist. We do not have any assets or liabilities measured at fair value on a recurring basis using quoted prices in an active market (Level 1) or significant unobservable inputs (Level 3). Gains and losses related to the fair value changes in the deferred compensation assets and liabilities are recorded in General and Administrative Expenses in the Consolidated Statements of Operations. Gains and losses related to the fair value of the interest rate swaps are recorded in Other Comprehensive Income.

Severance and Other Charges [Text Block] | In 2017, as part of the efforts to streamline its business, the Company recorded $1.1 million of severance compensation and other charges. In 2015, in response to lower commodity pricing for crude oil and reduced spending by our clients on their oil and gas fields, we reduced our cost structure, primarily through a reduction in our workforce, to better align with the decreasing activity levels into the foreseeable future. As a result of these cost reductions, we recorded severance charges of $8.8 million and a charge to income associated with the impairment of certain equipment and intangible assets and facility exit costs of $5.5 million . Also during 2015, we recorded loss contingencies for various ongoing legal issues of $8.6 million . See Note 11 - Commitments and Contingencies . |

We are a Netherlands company and we derive our revenue from services and product sales to clients primarily in the oil and gas industry. No single client accounted for 10% or more of revenue in any of the periods presented. We attribute service revenue to the country in which the service was performed rather than where the reservoir or project is located while we attribute product sales revenue to the country where the product was shipped as we feel this gives a clearer view of our operations. We do, however, have significant levels of service revenue performed and recorded in the U.S. that are sourced from projects on non-U.S. oilfields.

Significant Accounting Policies (Policies) | 12 Months Ended |
Dec. 31, 2017 | |
Accounting Policies [Abstract] | |
Accounts payable [Policy Text Block] | Accounts Payable Trade accounts payable are recorded at their invoiced amounts and do not bear interest. The carrying value of accounts payable is considered to be representative of its respective fair value. |
Pension and Other Postretirement Plans, Policy [Policy Text Block] | Pensions and Other Postretirement Benefits We provide a non-contributory defined benefit pension plan covering substantially all of our Dutch employees ("Dutch Plan") who were hired prior to 2007. As required by current accounting standards, we recognize net periodic pension costs associated with the Dutch plan in income from current operations and recognize the unfunded status of the plan, if any, as a long-term liability. In addition, we recognize as a component of other comprehensive income, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic pension cost. The projection of benefit obligation and fair value of plan assets requires the use of assumptions and estimates. Actual results could differ from those estimates. See Note 10 - Pension and Other Postretirement Benefit Plans . Furthermore, we maintain defined contribution plans for the benefit of eligible employees primarily in Canada, the Netherlands, the United Kingdom and the United States. We expense these contributions in the period the contribution is made. |
NonControlling Interests [Policy Text Block] | Non-controlling Interests We maintain non-controlling interests in several investment ventures and disclose such interests clearly as a portion of equity separate from the parent's equity. The amount of consolidated net income attributable to these non-controlling interests must also be clearly presented on the Consolidated Statements of Operations. In addition, when a subsidiary is deconsolidated, any retained non-controlling equity investment in the former subsidiary will be initially measured at fair value and recorded as a gain or loss. |
Income Tax, Policy [Policy Text Block] | Income Taxes We recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Consolidated Financial Statements or tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statement and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the asset is recovered or the liability is settled. We include interest and penalties from tax judgments in income tax expense. We record a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in our tax return. We also recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense. See Note 9 - Income Taxes . |
Comprehensive Income [Policy Text Block] | Comprehensive Income Comprehensive income is comprised of net income and other charges or credits to equity that are not the result of transactions with owners. Other comprehensive income consists of prior service costs and an unrecognized net actuarial gain and loss from a pension plan and changes in the fair value of our interest rate swaps. See Note 10 - Pension and Other Postretirement Benefit Plans and Note 14 - Derivative Instruments and Hedging Activities . |
Inventory, Policy [Policy Text Block] | Inventories Inventories consist of manufactured goods, materials and supplies used for sales or services to clients. Inventories are stated at the lower of cost or estimated net realizable value. Inventory costs are recorded at standard cost which approximates the first-in, first-out method. |
Prepaid Expenses and Other Current Assets [Policy Text Block] | Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets are comprised primarily of prepaid insurance, value added taxes and prepaid rents. |
Consolidation, Policy [Policy Text Block] | Principles of Consolidation The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the U.S. ("U.S. GAAP" or "GAAP"), and include the accounts of Core Laboratories and its subsidiaries for which we have a controlling voting interest and/or a controlling financial interest. The equity method of accounting is used to record our interest in investments in which we have less than a majority interest and do not exercise control but do exert significant influence. We use the cost method to record certain other investments in which we own less than 20% of the outstanding equity and do not exercise control or exert significant influence. We record non-controlling interest associated with consolidated subsidiaries that are less than 100% owned. All inter-company transactions and balances have been eliminated in consolidation. |
Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We evaluate our estimates on an ongoing basis and utilize our historical experience, as well as various other assumptions that we believe are reasonable in a given circumstance, in order to make these estimates. Actual results could differ from our estimates, as assumptions and conditions change. The following accounts, among others, require us to use critical estimates and assumptions: ▪ allowance for doubtful accounts; ▪ obsolete inventory; ▪ depreciation and amortization; ▪ long-lived assets, intangibles and goodwill; ▪ income taxes; ▪ pensions and other postretirement benefits; and ▪ stock-based compensation. Accounting policies relating to these accounts and the nature of these estimates are further discussed under the applicable caption. For each of these critical estimates it is at least reasonably possible that changes in these estimates will occur in the short term which may impact our financial position or results of operations. |
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Cash Equivalents Cash and cash equivalents include all short-term, highly liquid instruments purchased with an original maturity of three months or less. These items are carried at cost, which approximates fair value. |
Concentration of Credit Risk [Policy Text Block] | Concentration of Credit Risk Our financial instruments that potentially subject us to concentrations of credit risk relate primarily to cash and cash equivalents and trade accounts receivable. All cash and cash equivalents are on deposit at commercial banks or investment firms with significant financial resources. Our trade receivables are with a variety of domestic, international and national oil and gas companies. We had no clients who provided more than 10% of our revenue for the years ended December 31, 2017 , 2016 and 2015 . We consider our credit risk related to trade accounts receivable to be limited due to the creditworthiness and financial resources of our clients. We evaluate our estimate of the allowance for doubtful accounts on an on-going basis throughout the year. |
Concentration of Interest Rate Risk [Policy Text Block] | Concentration of Interest Rate Risk We are exposed to interest rate risk on our revolving credit facility (the "Credit Facility") debt, which carries a variable interest rate. We are exposed to interest rate risk on our Senior Notes which carry a fixed interest rate, but whose fair value will fluctuate based on changes in interest rates and market perception of our credit risk. |
Trade and Other Accounts Receivable, Policy [Policy Text Block] | Accounts Receivable Trade accounts receivable are recorded at their invoiced amounts and do not bear interest. We perform ongoing credit evaluations of our clients and monitor collections and payments in order to maintain a provision for estimated uncollectible accounts based on our historical collection experience and our current aging of client receivables outstanding, in addition to client's representations and our understanding of the economic environment in which our clients operate. Based on our review we establish or adjust allowances for specific clients and the accounts receivable as a whole, and recognize expense. When an account is determined to be uncollectible, we charge the receivable to our allowance for doubtful accounts. Our allowance for doubtful accounts totaled $2.6 million and $3.1 million at December 31, 2017 and 2016 , respectively. The net carrying value of accounts receivable is considered to be representative of its respective fair value. |
Property, Plant and Equipment, Policy [Policy Text Block] | Property, Plant and Equipment Property, plant and equipment are carried at cost less accumulated depreciation. Major renewals and improvements are capitalized while maintenance and repair costs are charged to expense as incurred. They are depreciated using the straight-line method based on their individual estimated useful lives, except for leasehold improvements, which are depreciated over the remaining lease term, if shorter. We estimate the useful lives and salvage values of our assets based on historical data as follows: Buildings and leasehold improvements 3 - 40 years Machinery and equipment 3 - 10 years When long-lived assets are sold or retired, the remaining costs and related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in income. These capitalized long-lived assets could become impaired if our operating plans or business environment changes. We review our long-lived assets, including definite-lived intangible assets, for impairment when events or changes in circumstances indicate that their net book value may not be recovered over their remaining service lives. Indicators of possible impairment may include significant declines in activity levels in regions where specific assets or groups of assets are located, extended periods of idle use, declining revenue or cash flow or overall changes in general market conditions. Whenever possible impairment is indicated, we compare the carrying value of the assets to the sum of the estimated undiscounted future cash flows expected from use, plus salvage value, less the costs of the subsequent disposition of the assets. If impairment is still indicated, we compare the fair value of the assets to the carrying amount, and recognize an impairment loss for the amount by which the carrying value exceeds the fair value. We did not record any material impairment charges relating to our long-lived assets held for use during the years ended December 31, 2017 , 2016 or 2015 . |
Goodwill and Intangible Assets, Policy [Policy Text Block] | Intangibles and Goodwill Intangible assets, including patents, trademarks, and trade names, are carried at cost less accumulated amortization. Intangibles with determinable lives are amortized using the straight-line method based on the estimated useful life of the intangible. Intangibles with indeterminable lives, which consist primarily of corporate trade names, are not amortized, but are tested for impairment annually or whenever events or changes in circumstances indicate that impairment is possible. We record goodwill as the excess of the purchase price over the fair value of the net assets acquired in acquisitions accounted for under the purchase method of accounting. We test goodwill for impairment annually, or more frequently if circumstances indicate possible impairment. We evaluated our goodwill for impairment by comparing the fair value of each of our reporting units, which are our reportable segments, to their net carrying value as of the balance sheet date. We estimated the fair value of each reporting unit using a discounted future cash flow analysis. Estimated future cash flows were based on the Company's best estimate of future performance. Our impairment analysis is quantitative; however, it includes subjective estimates based on assumptions regarding future growth rates, interest rates and operating expenses. If the carrying value of the reporting unit exceeds the fair value determined, an impairment loss is recorded to the extent that the implied fair value of the goodwill of the reporting unit is less than its carrying value. Any subsequent impairment loss could result in a material adverse effect upon our financial position and results of operations. We did not record impairment charges relating to our goodwill or our indefinite-lived intangible assets during the years ended December 31, 2017 , 2016 or 2015 . We have never identified nor recorded any impairments relating to the goodwill of our current continuing operations. |
Revenue Recognition, Policy [Policy Text Block] | Revenue Recognition We recognize revenue when we determine that the following criteria are met: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed or determinable; and (iv) collectability is reasonably assured. Services Revenue : We provide a variety of services to clients in the oil and gas industry. Where services are provided related to the testing and analysis of rock and fluids, we recognize revenue upon the provision of the test results or analysis to the client. For our design, field engineering and completion diagnostic services, we recognize revenue upon the delivery of those services at the well site. In the case of our consortium studies, revenue is recognized when the reservoir model solution is presented to our clients. We conduct testing and provide analysis services in support of our consortium studies recognizing revenue as the testing and analysis results are made available to our consortium members. Product Sales Revenue : We manufacture equipment that we sell to our clients in the oil and gas well industry. Revenue is recognized when title to that equipment passes to the client, which is typically when the product is shipped to the client or picked up by the client at our facilities, as set out in the contract. All advance client payments are classified as unearned revenue until services are performed or product title is transferred. |
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Currencies Our functional currency is the U.S. Dollar ("USD"). All inter-company financing, transactions and cash flows of our subsidiaries are transacted in USD. Our foreign entities remeasure monetary assets and liabilities to USD at year-end exchange rates, while non-monetary items are measured at historical rates. Revenue and expenses are remeasured at the applicable month-end rate, except for depreciation, amortization and certain components of cost of sales, which are measured at historical rates. For the years ended December 31, 2017 , 2016 and 2015 , we incurred net remeasurement loss es of $0.9 million , $1.8 million , and $4.5 million , respectively. These amounts were included in Other (Income) Expense, net in the accompanying Consolidated Statements of Operations. |
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | Stock-Based Compensation We have two stock-based compensation plans, as described in further detail in Note 13 - Stock-Based Compensation . For new awards issued and awards modified, repurchased or canceled, the compensation expense is equal to the fair value of the award at the date of the grant and is recognized in the Consolidated Statements of Operations for those awards earned over the requisite service period of the award. |
Earnings Per Share, Policy [Policy Text Block] | Earnings Per Share We compute basic earnings per common share by dividing net income attributable to Core Laboratories N.V. by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common share include additional shares in the weighted average share calculations associated with the incremental effect of dilutive restricted stock awards and contingently issuable shares, as determined using the treasury stock method. The following table summarizes the calculation of weighted average common shares outstanding used in the computation of diluted earnings per share (in thousands): For the Years Ended December 31, 2017 2016 2015 Weighted average basic common shares outstanding 44,153 43,479 42,747 Effect of dilutive securities: Performance shares 69 127 98 Restricted stock 42 64 63 Weighted average diluted common and potential common shares outstanding 44,264 43,670 42,908 |
Other assets [Policy Text Block] | Other Assets Cash surrender value of life insurance relates to postretirement benefit plans. See Note 10 - Pension and Other Postretirement Benefit Plans . Investments include unconsolidated affiliates accounted for under the equity method where the operations of these entities are in-line with those of our core businesses. These entities are not considered special purpose entities nor do we have special off-balance sheet arrangements through these entities. Other assets consisted of the following (in thousands): 2017 2016 Cash surrender value of life insurance $ 46,314 $ 39,059 Investments in unconsolidated affiliates 3,557 3,224 Other 5,257 4,841 Total other assets $ 55,128 $ 47,124 |
