In third quarter 2020, we sold our North Louisiana assets and retained certain gathering, transportation and processing obligations which extend into 2030. These are contracts where we will not realize any future benefit. The estimated obligations are included in current and long-term divestiture contract obligation in our consolidated balance sheets. In first three months 2023, we recorded accretion expense of $10.2 million compared to $11.0 million in the same period of the prior year. The estimated discounted divestiture contract obligation was $375.1 million at March 31, 2023.

In second quarter 2020, we negotiated capacity releases on certain transportation pipelines in Pennsylvania effective May 31, 2020 and extending through the remainder of the contract. The estimated remaining discounted obligation for these transportation capacity releases as of March 31, 2023 was $4.5 million.
