(Oil & Gas 360) – Chevron is preparing to expand drilling operations in Argentina’s Vaca Muerta shale formation, applying operational experience from the U.S. Permian Basin as the company evaluates a proposed $13.8 billion investment intended to increase production and improve development economics.The company plans to increase drilling rigs at its El Trapial block from one to three by early 2029, according to executives interviewed by Reuters. The proposed investment would extend over 30 years and remains subject to Argentine government approval.Chevron previously established a target of tripling its Argentine production to approximately 195,000 barrels of oil equivalent per day by 2035. Management believes improvements in drilling efficiency and additional equipment could accelerate that timeline.El Trapial currently produces approximately 40,000 barrels of oil equivalent per day. Chevron also holds a 50% interest in the Loma Campana and Narambuena developments, both operated by Argentina’s YPF.The expansion reflects growing interest in Vaca Muerta, one of the world’s largest unconventional petroleum formations, as Argentina seeks to attract international investment and increase energy exports.Wood Mackenzie estimates that Argentina’s petroleum production will average approximately 910,000 barrels of oil equivalent per day in 2026, representing a 42% increase from 2023.However, resource quality alone has not eliminated the challenges facing unconventional development.Chevron estimates that bringing a well into production in Vaca Muerta costs approximately 30% more than in the Permian Basin. Limited local supply chains, transportation distances, and infrastructure requirements contribute to the difference.Hydraulic fracturing sand, for example, must be transported nearly 2,000 kilometers from suppliers elsewhere in Argentina.Chevron intends to improve operating efficiency by maintaining more continuous drilling and completion activity, reducing interruptions between well construction and hydraulic fracturing operations.These improvements could lower unit development costs and strengthen project economics, although their financial impact will depend on equipment utilization, service pricing, and well productivity.Export infrastructure represents another important consideration.Chevron holds an interest in the Vaca Muerta Oil Sur pipeline project, which is intended to expand access to international crude markets. Additional transportation capacity could reduce logistical constraints and improve the competitiveness of Argentine production.For oilfield service companies, continued development could create opportunities in drilling equipment, pressure pumping, artificial lift, logistics, and production infrastructure.Argentina’s investment environment has also become an important factor in capital allocation. Economic reforms under President Javier Milei have improved conditions for some energy projects, but currency exposure, regulatory stability, and political uncertainty remain considerations for international operators.For investors, Vaca Muerta’s long-term potential will depend on whether productivity gains and infrastructure investment can offset higher operating costs.Chevron’s expansion plans demonstrate increasing confidence in Argentina’s unconventional resources, while underscoring the importance of competitive project returns when international shale developments compete for capital against established U.S. producing regions.Disclaimer This informational, opinion, and insights article is provided for informational purposes only and does not constitute investment, legal, or financial advice.
