| Named Executive Officers, Footnote [Text Block] | (1) The dollar amounts reported are the amounts of total compensation reported for Christopher A. Wright (our Chairman/CEO) for each corresponding year in the “Total” column of the Summary Compensation Table provided above. (3) The dollar amounts reported represent the average of the amounts reported for our NEOs as a group (excluding Mr. Wright) in the “Total” column of the Summary Compensation Table provided above. The NEOs (excluding Mr. Wright) included for purposes of calculating the average amounts in each applicable year are Messrs. Stock, Gusek, Elliott and Gosney. | |||
| Peer Group Issuers, Footnote [Text Block] | (5) The peer group selected for each listed year consists of the Philadelphia Oil Service Index (the “OSX”). We also use this peer group for purposes of the Stock Performance Graph set forth in “Item 5- Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities” of our Annual Report on Form 10-K for the year ended December 31, 2022. | |||
| PEO Total Compensation Amount | $ 5,747,485 | $ 4,611,372 | $ 3,310,114 | |
| PEO Actually Paid Compensation Amount | 12,201,790 | 3,946,524 | 2,493,998 | |
| Adjustment To PEO Compensation, Footnote [Text Block] | (2) The dollar amounts reported represent the amount of “compensation actually paid” to Mr. Wright, as computed in accordance with Item 402(v) of SEC Regulation S-K. The dollar amounts reported do not reflect the actual amount of compensation earned by or paid to Mr. Wright during the applicable year. In accordance with the requirements of Item 402(v) of SEC Regulation S-K, the following adjustments were made to Mr. Wright’s total compensation for each year to determine the compensation actually paid to Mr. Wright: Year Reported Less Grant Date Year-End Change in Change in Compensation 2022 5,747,485 (3,406,258) 4,405,023 3,612,975 1,842,565 12,201,790 2021 4,611,372 (3,801,972) 2,841,227 99,171 196,725 3,946,524 2020 3,310,114 (2,876,014) 3,082,298 (209,920) (812,480) 2,493,998 | |||
| Non-PEO NEO Average Total Compensation Amount | 2,367,374 | 2,028,596 | 1,218,682 | |
| Non-PEO NEO Average Compensation Actually Paid Amount | 4,567,954 | 1,738,700 | 909,552 | |
| Adjustment to Non-PEO NEO Compensation Footnote [Text Block] | (4) The dollar amounts reported represent the average amount of “compensation actually paid” to the NEOs as a group (excluding Mr. Wright), as computed in accordance with Item 402(v) of SEC Regulation S-K. The NEOs (excluding Mr. Wright) included for purposes of calculating the average amounts in each applicable year are Messrs. Stock, Gusek, Elliott and Gosney. The dollar amounts reported do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding Mr. Wright) during the applicable year. In accordance with the requirements of Item 402(v) of SEC Regulation S-K, the following adjustments were made to average total compensation for the NEOs as a group (excluding Mr. Wright) for each year to determine the compensation actually paid: Year Reported Less Grant Date Year-End Change in Change in Average 2022 2,367,374 (1,146,682) 1,482,906 1,259,414 604,943 4,567,954 2021 2,028,596 (1,515,516) 1,132,550 22,787 70,282 1,738,700 2020 1,218,682 (957,726) 1,026,420 (68,658) (309,165) 909,552 | |||
| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | Compensation Actually Paid and Cumulative TSR As demonstrated by the following graph, the amount of compensation actually paid to Mr. Wright and the average amount of compensation actually paid to our NEOs as a group (excluding Mr. Wright) is generally aligned with our cumulative TSR over the three years presented in the “ Pay Versus Performance Table for 2022.” The alignment of compensation actually paid with our cumulative TSR over the period presented is due to the fact that a significant portion of the compensation actually paid to our NEOs is comprised of equity awards. | |||
| Compensation Actually Paid vs. Net Income [Text Block] | Compensation Actually Paid and Net Income (Loss) As demonstrated by the following table, the amount of compensation actually paid to Mr. Wright and the average amount of compensation actually paid to other NEOs as a group (excluding Mr. Wright) is generally aligned with our net income (loss) over the three years presented in the “Pay Versus Performance Table for 2022.” While we do not use net income (loss) as a performance measure in the overall executive compensation program, the measure of net income (loss) is correlated with the measures of Pre-Tax EPS and ROCE, which we do use in setting goals for annual incentive compensation, and Comparative ROCE, which we use both in setting goals for annual incentive compensation and the vesting of performance-based RSU awards. | |||
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | Compensation Actually Paid and Adjusted ROCE As demonstrated by the following table, the amount of compensation actually paid to Mr. Wright and the average amount of compensation actually paid to our other NEOs as a group (excluding Mr. Wright) is generally aligned with our Adjusted ROCE over each of the three years presented in the “ Pay Versus Performance Table for 2022.” | |||
| Total Shareholder Return Vs Peer Group [Text Block] | For each of the three years presented in the “Pay Versus Performance Table for 2022,” our cumulative TSR exceeded that of peers contained in the OSX stock index. The following table details our cumulative TSR in comparison to the OSX cumulative TSR for each of the measurement periods (determined in accordance with SEC regulations). | |||
| Tabular List [Table Text Block] | Performance Metrics The most important financial performance measures that we use to link executive compensation actually paid to the NEOs for the most recently completed fiscal year to our performance are as follows: • Pre-tax Earnings Per Share • ROCE • Adjusted ROCE • Comparative ROCE | |||
| Total Shareholder Return Amount | 147.11 | 88.85 | 94.44 | |
| Peer Group Total Shareholder Return Amount | 107.11 | 67.34 | 56.62 | |

| Non-GAAP Measure Description [Text Block] | (7) Adjusted ROCE is equal to the Company’s 2022 income before taxes and loss (gain) on remeasurement of liability under tax receivable agreements, plus interest expense and stock-based compensation expense, divided by the simple average of capital (debt and equity) employed at December 31, 2022 and 2021. We rank our Adjusted ROCE against those of the ROCE Peer Group to determine Comparative ROCE, which is used as a metric to determine a portion of annual incentive compensation and the vesting of performance-based RSU awards. While we use numerous financial and non-financial performance measures for the purpose of evaluating performance for our compensation programs, we have determined that our Adjusted ROCE is the financial performance measure that, in our assessment, represents the most important performance measure (that is not otherwise required to be disclosed in this table) used by us to link compensation actually paid to our NEOs for the most recently completed fiscal year, to our performance. | |||
