EXCLUSIVE-Mexico's Pemex seeks control of U.S. oil firm's billion-barrel find

When U.S. oil firm Talos Energy found nearly a billion barrels off Mexico's southern Gulf coast two years ago, it marked the first discovery by a foreign firm since the oil industry was nationalized eight decades earlier. Now Mexico's state-run oil firm Pemex wants to take over the lucrative project, according to two former Mexican energy officials and two company executives with knowledge of internal Pemex discussions. The Pemex push to run drilling in the oilfield comes amid the ongoing drive by leftist President Andres Lopez Obrador to return more control of Mexico's energy sector to its state oil firm.
