Asset Retirement Obligation Disclosure [Abstract] |
Asset Retirement Obligations | Note 14 — Asset Retirement Obligations Asset retirement obligations (“AROs”) are recorded at fair value and consist of estimated costs for subsea infrastructure P&A activities associated with our oil and gas properties acquired from Marathon Oil in January 2019, which costs are discounted to present value using a credit-adjusted risk-free discount rate. After its initial recognition, an ARO liability is increased for the passage of time as accretion expense, which is a component of our depreciation and amortization expense. An ARO liability may also change based on revisions in estimated costs and/or timing to settle the obligations. The following table describes the changes in our AROs (in thousands):
AROs at January 1, 2020 | $ | 28,258 |
Accretion expense | 1,304 |
AROs at June 30, 2020 | $ | 29,562 |
