US supermajor ExxonMobil is selling for $750 million its stake in one of the world’s first actively produced shale plays, the Barnett shale of Texas in the US, to BKV Corporation.

ExxonMobil in 2020 removed the company's Barnett holdings from its development plan and had been actively marketing the assets since last November.

“We are focused on delivering the most competitive returns to our shareholders by developing opportunities with the lowest cost of supply and further strengthening our industry-leading upstream position,” said Liam Mallon, president of ExxonMobil Upstream Company.
