Asset Retirement Obligations

Note 15 — Asset Retirement Obligations

Our AROs relate to mature offshore oil and gas properties that we acquired with the intention to perform decommissioning work at the end of their life cycles. In August 2022, we acquired from MP Gulf of Mexico, LLC (“MP GOM”), a joint venture controlled by Murphy Exploration & Production Company – USA, all of MP GOM’s 62.5% interest in the Thunder Hawk Field, in exchange for the assumption of MP GOM’s abandonment obligations (initially estimated at $23.6 million). Our AROs also include P&A costs associated with our Droshky oil and gas properties (Note 4). The following table describes the changes in our AROs (in thousands):
