Chevron boosts exploration budget by 50 percent to diversify global portfolio

Chevron is increasing its exploration expenditure by 50 percent this year, aiming to diversify its upstream portfolio and mitigate concentration risks in geopolitically unstable regions. The company plans to spend more than $1.5 billion on exploration activities, a significant rise from the figure of just under $1 billion recorded in 2025. This strategic shift marks a return to high-impact frontier exploration after several years of primary focus on the United States Gulf of Mexico and the Permian shale basin.

The decision to expand the exploration program is driven by the need to renew the company’s asset base and offset natural production declines at existing fields. Kevin McLachlan, the vice president of exploration who joined Chevron from TotalEnergies last year, stated that the company required increased spending to generate new prospects. He noted that the additional investment is primarily directed towards seismic data, which is essential for creating viable exploration ideas. McLachlan explained that the company previously lacked sufficient exposure to new opportunities, prompting the substantial budget increase.

Geopolitical tensions, specifically the conflict involving Iran and the disruption of oil and gas flows through the Strait of Hormuz, have underscored the vulnerabilities of relying on a single region for large supply volumes. Analysts at Wood Mackenzie have observed that the Middle East conflict has highlighted the risks associated with focusing on unstable areas. They noted that the need for portfolio renewal is increasing the appetite for exploration risk among upstream firms, with companies taking on more exposure and positioning earlier in their exploration targets. The spike in oil and gas prices following the recent conflict has also provided companies with additional financial resources to fund these expanded budgets.

Chevron has been aggressively acquiring exploration acreage over the past two years, increasing its holdings by 35 percent in the last year alone. The company’s 2027 program includes drilling 20 exploration wells and potentially up to six appraisal wells, a significant increase from the approximately 10 exploration wells drilled annually two years ago. McLachlan indicated that about 50 percent of the current exploration budget is now allocated to undeveloped frontier basins, up from 20 percent a few years ago. This shift has led to recent discoveries in West Africa, including Nigeria and Angola, and the company plans to drill the Nabba-1X exploration well in Namibia by the end of the year.

CEO Mike Wirth has expressed satisfaction with the renewed exploration efforts, stating that the company has built the largest and highest-quality opportunity set in years. Wirth acknowledged that previous results were limited because the team was operating within a narrow range, but he emphasized that the company now possesses a deep inventory of opportunities. McLachlan added that every successful well adds information and confidence, creating potential pathways for future growth. The company’s strategy focuses on adding reserves and production growth opportunities in regions including Guyana, Angola, Namibia, Nigeria, Guinea-Bissau, Equatorial Guinea, Egypt, and the Eastern Mediterranean.
