Chevron Lifts Exploration Spending 50% and Targets Frontier Basins

Chevron will raise its exploration budget this year by roughly 50% versus 2025, with spending that will exceed 1.5 billion dollars, according to the company's vice president of exploration, Kevin McLachlan, in an interview with the Financial Times published in September 2026.

The figure contrasts with the budget of just under 1 billion dollars in 2025, according to OilPrice, which covered the interview. For the region, the data marks a shift in capital after years in which the U.S. supermajor concentrated its growth in the Permian Basin and the Gulf of Mexico, where its Ballymore, Whale and Anchor assets operate. The Gulf basin is shared between the United States and Mexico, so a greater exploration appetite from an oil company of its size reads as a signal of investment in the region's waters.

McLachlan explained that the company increased spending on seismic because without that data no prospects are generated. Improving subsurface information is the step before any drilling campaign. As for activity, Chevron was drilling about 10 exploration wells per year two years ago; its plan for 2027 includes 20 exploration wells and up to six appraisal wells. In addition, around 50% of the exploration budget today goes to undeveloped frontier basins, versus 20% a few years ago.

The third-quarter 2026 results report, presented on October 30, provides the numbers that underpin the bet: earnings of 9,924 million dollars and production of 3,980 thousand barrels of oil equivalent per day, with exploration spending of 259 million in the quarter and 720 million so far in 2026. U.S. production, in which Gulf of Mexico start-ups weigh, remained above 2 million barrels per day for the fifth consecutive quarter.

What follows is the season of capital plans for 2027, when the company will detail how much of that budget goes to the Gulf of Mexico and to technical cooperation with Mexico. Also in the spotlight will be the Nabba-1X well in Namibia, which Chevron expects to drill before the end of 2026, as a test of whether the new exploration program finds reserves.
