In 2020, Chesapeake Energy Corporation filed for bankruptcy, and as part of its restructuring plan, it decided to sell some of its assets to pay off its debts. One of the assets that Chesapeake sold was its South Mansfield Haynesville shale acreage, comprising 50,000 net mineral acres, which it sold to Williams Companies, Inc in December 2020. In August 2021, Williams announced an upstream JV with GeoSouthern (GEP Haynesville II) to develop the South Mansfield asset in order to enhance their strategy of connecting the best supplies of affordable, reliable and clean natural gas with growing customer demand. In May 2023, Alan Armstrong of Williams stated "During the last downturn, particularly in 2020, where we had customers that owed us for expansions and we brought in new operators to develop those...in the Haynesville, GeoSouthern (GEP Haynesville II) has been the operator there and they have done a fantastic job of growing the volumes in the Haynesville for us."
