​ (1) In late third quarter 2021, management completed its evaluation of the performance of a saltwater disposal asset, located in Eddy County, New Mexico and concluded that the well should be shut-in and taken out of service. We drilled this well in the second quarter of 2017 and encountered technical difficulties requiring significant incremental capital expenditure. The asset was put into service in May of 2018. During July 2021, we re-entered the well bore to address anomalies. After technical testing, management concluded that it was probable that abandoning the asset was the most prudent course of action as the well is unable to remain in service in its current condition. Accordingly, we have removed the cost and the associated accumulated depreciation and recognized a charge of $27.4 million for the remaining net book value of the well. The charge has been reflected in Abandoned Well Costs in the Statements of Operations.
