Decommissioning Liabilities [Abstract]
Decommissioning Liabilities	(10) Decommissioning Liabilities We account for decommissioning liabilities under ASC 410 – Asset Retirement Obligations. Our decommissioning liabilities are associated with an oil and gas property and include liabilities related to the plugging of wells, removal of the related platform and equipment and site restoration. We review the adequacy of our decommissioning liabilities whenever indicators suggest that the estimated cash flows and/or relating timing needed to satisfy the liability have changed materially. The Successor had decommissioning liabilities of $173.1 million as of September 30, 2021 and the Predecessor had decommissioning liabilities of $142.7 million as of December 31, 2020, respectively, including decommissioning liabilities included within liabilities held for sale. In connection with fresh start accounting, we now present all asset retirement obligations separately as decommissioning liabilities on the balance sheet. Previously, certain of these decommissioning liabilities were included as a component of other long-term liabilities.

We account for decommissioning liabilities under ASC 410 – Asset Retirement Obligations. Our decommissioning liabilities are associated with an oil and gas property and include liabilities related to the plugging of wells, removal of the related platform and equipment and site restoration. We review the adequacy of our decommissioning liabilities whenever indicators suggest that the estimated cash flows and/or relating timing needed to satisfy the liability have changed materially. The Successor had decommissioning liabilities of $173.1 million as of September 30, 2021 and the Predecessor had decommissioning liabilities of $142.7 million as of December 31, 2020, respectively, including decommissioning liabilities included within liabilities held for sale. In connection with fresh start accounting, we now present all asset retirement obligations separately as decommissioning liabilities on the balance sheet.
