Facing a dip in oil prices in 2019, the CEO of California-based Chevron, Mike Wirth, warned there was no “silver bullet” to improve returns as long as oil markets remained flat. And sure enough, full-year net income fell 80% to $2.9 billion. Revenues and cash flow declined, too, forcing the company to cut unprofitable projects—and to refocus on the U.S. shale sector. Its assets in Venezuela, which it held on to even as other oil companies left the country amid economic collapse, have also seen a new twist. This spring, the Trump administration ordered Chevron to “wind down” its operations in the country.
