International oil companies are prioritizing shareholder returns over reserve expansion, according to a BusinessDay investigation, as major firms allocate over $100 billion annually to dividends and stock buybacks, leaving limited resources for exploration. Exxon Mobil, Chevron, BP, Shell, and TotalEnergies have collectively funneled 80% of their combined earnings into shareholder payouts since the 2020 oil price crash, which devastated balance sheets and investor confidence. This shift has coincided with a 49% year-over-year decline in capital expenditure among the 30 largest U.S. exploration and production companies in 2025, with exploration spending dropping 11% to $4.8 billion, according to Ernst & Young – Professional Services.
The industry’s focus on profitability has led to a decoupling of production and reserve growth. Despite reduced exploration, U.S. oil production hit an all-time high in 2025, driven by efficiency gains in shale operations. Analyst Matt Melnar of EY noted that producers are balancing short-term returns with long-term resilience, as reserve replacement metrics no longer reflect the full picture of industry dynamics. “The sector is navigating a complex trade-off between immediate shareholder demands and the need to maintain long-term resource bases,” he said.
Shale operators are leveraging advanced technologies to maximize output with less capital. Longer horizontal wells, some exceeding three miles, and simultaneous completions have slashed costs and accelerated production timelines. EY’s report highlighted the role of deep learning models in analyzing seismic data and historical drilling logs to identify high-permeability zones with greater precision. Predictive analytics now optimize fracking operations, while AI-driven geosteering adjusts drilling paths in real time, according to the study.
The shift has also led to the depletion of drilled-but-uncompleted wells (DUCs), which cost $5 million to $6 million to complete compared to $8 million to $10 million for new wells. The U.S. DUC inventory fell to 4,972 wells in May 2025, the lowest since 2013, as producers prioritize cost-effective completions over new drilling. This strategy, however, has contributed to a 11% annual decline in reserve additions from discoveries and extensions—the first such drop in five years, EY found.
Natural gas, by contrast, has seen a surge in reserves, with a 14% year-over-year increase and 21% growth in discoveries, outpacing production by 18%. Reserve revisions turned positive for the first time in five years, signaling a strategic pivot toward gas. EY’s Patrick Jelinek attributed this to the sector’s alignment with energy security, industrial needs, and AI infrastructure demands. “Natural gas is becoming a cornerstone of the energy transition,” he said, emphasizing its role in balancing intermittent renewables and supporting industrial growth.
The industry’s reliance on efficiency gains and cost-cutting has raised concerns about long-term resource sustainability. While current production levels remain robust, the decline in reserve replacement risks future supply stability. EY’s analysis underscores a sector in flux, where technological innovation and financial discipline are reshaping traditional energy dynamics. As companies navigate these challenges, the interplay between shareholder expectations and energy security will define the industry’s trajectory.
The findings highlight broader implications for global energy markets, particularly in regions dependent on oil and gas. With natural gas gaining strategic importance, producers are reevaluating their portfolios to align with evolving demand trends. The shift reflects a sector adapting to a rapidly changing landscape, where profitability and sustainability must coexist.
BusinessDay’s investigation reveals a fundamental transformation in the oil and gas industry, driven by financial priorities and technological advancements. As companies prioritize short-term returns, the long-term implications for energy security and reserve growth remain uncertain, raising critical questions about the future of global hydrocarbon supply.
The data underscores the need for policymakers and stakeholders to monitor the sector’s evolving strategies. While efficiency gains have sustained production, the reduced focus on exploration could impact future energy availability. EY’s research provides a critical lens into these trends, offering insights into the complex decisions shaping the industry’s next chapter.
