HOUSTON, (Reuters) – The former head of Exxon Mobil’s XOM.N shale oil and gas business will return as senior vice president over the company’s most important U.S. oil operation following his successor’s arrest earlier this month. Cahir has previously run Exxon’s shale business including its XTO unit as senior vice president of Unconventional from July 2020 through April 2022. Unconventional is Exxon’s term for shale oil and gas. That purchase will bring Exxon’s shale output to 1.3 million barrels of oil and gas (boepd), more than a quarter of its overall production. Cahir led Exxon’s Unconventional unit as senior vice president as Exxon implemented tough costs cuts following the collapse of oil and gas prices during the pandemic.
