Variable Interest Entity [Line Items]
Methodology for Determining Whether Entity is Primary Beneficiary			From April 3, 2018 to March 1, 2022, we treated Superior as a variable interest entity (VIE) because the equity holders as a group (Unit Corporation and SP Investor) lacked the power to control without the Operator. The Agreement and MSA gave us the power to direct the activities that most significantly affect Superior's operating performance through common control of the Operator. Accordingly, Unit was considered the primary beneficiary and consolidated the financial position, operating results, and cash flows of Superior.
