Big Oil’s Production Keeps Soaring Despite Deep Spending Cuts

Despite a 49% year-over-year decline in capital expenditure for the United States' 30 largest publicly traded exploration and production companies, oil production by the group reached an all-time high in 2025. Revenue for the companies increased by 7%, indicating that reduced spending on drilling has not significantly impacted their bottom line.

EY's Matt Melnar highlighted that reserve replacement metrics alone no longer provide a complete picture, as producers are balancing production goals, shareholder returns, and long-term portfolio resilience. The shift toward shorter-cycle, high-return assets has been driven by drilling efficiency gains, technological advancements, and a strategic focus on AI, machine learning, and predictive analytics to maximize production efficiency and extend the lifespan of oil and gas wells.

Despite the reduction in spending, Big Oil continues to explore ways to maintain production volumes, such as utilizing drilled but uncompleted wells (DUCs) and leveraging deep learning models and AI-driven systems to optimize drilling and production processes.
