U.S. President Donald Trump said ExxonMobil, the largest U.S. oil major, was among companies planning to do business in Venezuela, though Exxon declined to comment. A return would reverse the company’s exit nearly two decades ago after Venezuela nationalized its assets. Exxon operates Guyana’s Stabroek Block, which produces more than 900,000 barrels of oil a day. Trump also named Chevron and other U.S. oil companies, saying American firms were bidding on opportunities and taking millions of barrels to refineries in Texas, Louisiana and elsewhere. His comments followed U.S. forces’ capture and removal of former President Nicolas Maduro from power in January and efforts to restart Venezuelan oil production. Exxon CEO Darren Woods had called Venezuela "uninvestable" in January without stronger investment protections, although Exxon said in March it would send a technical team to assess opportunities. Venezuelan and American officials are expected to sign a deal later this week in Caracas giving the U.S. access to a fifth of Venezuela’s crude reserves, while Chevron, GE Vernova, India’s ONGC, Italy’s Eni and Colombia’s GeoPark are also preparing agreements for new or expanded projects.
