Expenditures for upstream represented 88 percent of the companywide total in 2018.Michael K. Wirth, Chevron’s chairman of the board and chief executive officer said: “We reached significant milestones with upstream major capital projects in 2018, including the start-up of Wheatstone Train Two, our fifth operated LNG train in Australia. We also continued the ramp-up of the Permian Basin in Texas and New Mexico, started production from the Big Foot Project in the Gulf of Mexico, and continued to progress our Future Growth Project at the company’s 50 percent-owned affiliate, Tengizchevroil, in Kazakhstan.”“Our net oil-equivalent production grew more than 7 percent in 2018 to a record 2.93 million barrels per day. We expect that 2019 production will continue to grow by 4 to 7 percent, excluding the impact of asset sales,” Wirth said.The company added approximately 1.46 billion barrels of net oil-equivalent proved reserves in 2018. These additions, which are subject to final reviews, equate to approximately 136 percent of net oil-equivalent production for the year. The largest additions were from the Permian Basin in the United States and the LNG projects in Australia, Chevron said.
