Fair Value Disclosures [Abstract]
Fair Value Measurement	14. Fair Value Measurement The Company is subject to ASC 820 – Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Inputs are used in applying the various valuation techniques and broadly refer to the assumptions that market participants use to make valuation decisions, including assumptions about risk. Inputs may include price information, volatility statistics, specific and broad credit data, liquidity statistics, and other factors. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Management considers observable data to be market data which is readily available, regularly distributed or updated, reliable and verifiable, not proprietary, and provided by independent sources that are actively involved in the relevant market. The categorization of a financial instrument within the hierarchy is based upon the pricing transparency of the instrument and does not necessarily correspond to management’s perceived risk of that instrument. Level 1 – Fair values are based on unadjusted quoted prices in active markets that are accessible at the measurement date of identical, unrestricted assets. Level 2 – Fair values are based on quoted prices for markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly. Level 3 – Inputs that are unobservable and significant to the overall fair value measurement and include situations where there is little, if any, market activity for the asset or liability. The Company’s proved oil and gas properties are assessed for impairment on a periodic basis. If the Company’s proved properties are determined to be impaired, the carrying basis of the properties is adjusted down to fair value. This represents a fair value measurement that would qualify as a non-recurring Level 3 fair value measurement. No impairment of proved properties was recorded for the three months ended March 31, 2023 and 2022. The fair value of the Company’s commodity derivative instruments (Level 2) was estimated using quoted forward prices for commodities, volatility factors, discounted cash flows and credit risk adjustments. The fair value of the Company's interest rate swap (Level 2) was estimated using quoted SOFR curves, discounted cash flows and credit risk adjustments. See “Note 13 – Derivative Instruments” for further information on the fair value of the Company’s derivative instruments. The fair value of the Company’s Public Warrants was determined using readily observable, publicly-traded prices (Level 1) for the warrants as of March 31, 2023 and December 31, 2022. The fair value of the Company’s Private Placement Warrants was estimated utilizing a Black-Scholes model using a range of significant unobservable inputs (Level 3) as of March 31, 2023 and December 31, 2022. See “Note 12 – Warrants” for further information on the fair value of the Company’s Public Warrants and Private Placement Warrants. The carrying values of cash, accrued revenue, accounts receivable, accounts payable, and accrued liabilities are considered to be representative of their respective fair values due to the short-term nature of these instruments. The carrying amount of debt outstanding pursuant to our 2026 Senior Notes and Sitio Revolving Credit Facility approximates fair value as the borrowings bear interest at variable rates which are reflective of current market conditions (Level 2). Certain nonfinancial assets and liabilities, such as assets and liabilities acquired in a business combination, are measured at fair value on a nonrecurring basis on the acquisition date and are subject to fair value adjustments under certain circumstances. Inputs used to determine such fair values are primarily based upon internally-developed engineering and geology models, publicly-available drilling disclosures, a risk-adjusted discount rate, and publicly-available data regarding mineral transactions consummated by other buyers and sellers (Level 3). Mineral assets not acquired through a business combination are measured at fair value on a nonrecurring basis on the acquisition date. The original purchase price of mineral assets is allocated between proved and unproved properties based on the estimated fair values. Inputs used to determine such fair values are primarily based upon internally-developed engineering and geology models, publicly-available drilling disclosures, a risk-adjusted discount rate, and publicly-available data regarding mineral transactions consummated by other buyers and sellers (Level 3). PSU awards are valued utilizing the Monte Carlo Simulation pricing model, which calculates multiple potential outcomes for an award and establishes grant date fair value based on the most likely outcome. The inputs for the Monte Carlo model are designated as Level 2 within the valuation hierarchy. See “Note 11 – Share-Based Compensation” for further information on the fair value of the Company's PSU awards.

14. Fair Value Measurement

The Company is subject to ASC 820 – Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Inputs are used in applying the various valuation techniques and broadly refer to the assumptions that market participants use to make valuation decisions, including assumptions about risk. Inputs may include price information, volatility statistics, specific and broad credit data, liquidity statistics, and other factors. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Management considers observable data to be market data which is readily available, regularly distributed or updated, reliable and verifiable, not proprietary, and provided by independent sources that are actively involved in the relevant market. The categorization of a financial instrument within the hierarchy is based upon the pricing transparency of the instrument and does not necessarily correspond to management’s perceived risk of that instrument.

Level 1 – Fair values are based on unadjusted quoted prices in active markets that are accessible at the measurement date of identical, unrestricted assets.

Level 2 – Fair values are based on quoted prices for markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.

Level 3 – Inputs that are unobservable and significant to the overall fair value measurement and include situations where there is little, if any, market activity for the asset or liability.

The Company’s proved oil and gas properties are assessed for impairment on a periodic basis. If the Company’s proved properties are determined to be impaired, the carrying basis of the properties is adjusted down to fair value. This represents a fair value measurement that would qualify as a non-recurring Level 3 fair value measurement. No impairment of proved properties was recorded for the three months ended March 31, 2023 and 2022.

Inputs used to determine such fair values are primarily based upon internally-developed engineering and geology models, publicly-available drilling disclosures, a risk-adjusted discount rate, and publicly-available data regarding mineral transactions consummated by other buyers and sellers (Level 3).

Mineral assets not acquired through a business combination are measured at fair value on a nonrecurring basis on the acquisition date.
