Exxon Mobil Corp. (IW 500/1) has overtaken rivals to become the most active driller in the Permian Basin, showing the urgency with which the world’s biggest oil company by market value is pursuing U.S. shale.
Even after a slow start in the region of West Texas and New Mexico, Exxon is now operating more drilling rigs than Concho Resources Inc., which merged with RSP Permian Inc. earlier this year to create one of the biggest Permian-focused explorers, according to statistics from RigData Inc. supplied to Bloomberg Intelligence.
