Argentina’s Oil Production Soars as Vaca Muerta Breaks New Records

Argentina’s massive shale oil and gas boom is going from strength to strength. The economically crisis-prone South American country yet again reported record monthly oil and natural gas production for May 2026. This couldn’t come at a better time for Argentina and South America. Rising global geopolitical risks, notably due to war in the Middle East, and domestic economic hazards hold the potential to derail the significant economic gains Argentina has made over the last two years.Ministry of Economy data shows May 2026 oil production hit an all-time high of 887,227 barrels per day. This represents a 0.6% increase month over month and is an impressive 19% greater than the same period a year earlier. Natural gas output also rose to 5.5 billion cubic feet per day, which was just shy of the record 5.7 billion cubic feet daily reported for July 2025. Indeed, May 2026 natural gas production was 5.4% greater than a month prior and a stunning 11% higher year over year.It is the massive shale boom underway in the 8.6-million-acre Vaca Muerta formation that is responsible for this solid production growth. For May 2026, shale oil comprised 70.6% of Argentina’s total oil production, while shale gas made up 69.8% of total output. Those ratios are at record highs for shale oil and gas as a proportion of Argentina’s total hydrocarbon output. This is a game changer for Argentina, which recently overtook Colombia to cement its place as South America’s fourth largest oil producer.The Vaca Muerta shale formation, which is regularly compared to the Eagle Ford shale, is in the early stages of development. Drillers in the formation are still in that phase of deciding where the core producing areas are located. The Vaca Muerta is regarded as one of the most promising unconventional oil and gas plays globally, containing an estimated 16 billion barrels of recoverable oil and 308 trillion cubic feet of recoverable natural gas resources. This all points to tremendous future unconventional hydrocarbon production growth for Argentina.Many of the Vaca Muerta shale formation’s characteristics are superior to U.S. shales, even the prolific Permian, which is the largest oil-producing basin in the United States. The formation’s shale is significantly thicker than the Permian, with it estimated to be at least double the width, allowing for more horizontal landings per pad and more frac stages per well. The Vaca Muerta’s organic content exceeds that found in most U.S. shale plays, while its reservoir pressure is significantly higher.As a result, wells drilled in the Vaca Muerta are more efficient and have a longer more productive lifespan than more mature U.S. shale plays such as the Permian. This offsets the higher drilling costs in Argentina caused primarily by infrastructure constraints and a lack of operational resources in the Vaca Muerta. These negatives are being addressed with the federal government, in the capital Buenos Aires, driving greater investment in essential facilities needed to develop the Vaca Muerta.The Vaca Muerta has an estimated breakeven cost of $36 to $45 per barrel, which is lower than most U.S. shale plays. The light sweet crude oil produced from the geological formation is particularly attractive for energy companies, especially in a world where there is an aggressive push to reduce emissions. The oil produced has an API gravity of 39 to 41 degrees and sulfur content of less than 0.5%. This makes that petroleum easier and cheaper to refine than the heavier sour grades produced throughout much of South America.Oil production in the Vaca Muerta has an industry-low carbon intensity of just under 16 kilograms of carbon dioxide emitted per barrel of petroleum lifted. Some estimates put this important number even lower, with Argentina’s YPF, the largest acreage holder and producer in the Vaca Muerta, claiming that only 12 kilograms of carbon is released for every barrel of shale oil it produces. These are impressive figures well below the global oil industry average of 23 kilograms of carbon dioxide emitted for every barrel produced.For those reasons, the Vaca Muerta continues attracting considerable attention from foreign energy companies. Estimates put 2026 upstream investment in the Vaca Muerta at around $10 billion. YPF, which was nationalized by President Cristina de Kirchner in 2012, budgeted 2026 capital expenditures of $5.8 billion, with around 70% to be spent on the company’s unconventional upstream acreage in the Vaca Muerta. This represents a solid increase over the $4.5 billion invested during 2025.Argentina’s national oil company has earmarked significant capital expenditure of $35.7 billion between 2025 and 2030, with most of that capital to be directed to upstream exploration and production operations in its Vaca Muerta acreage. It isn’t only YPF investing in the shale formation; Big Oil and smaller privately owned drillers are investing considerable capital to acquire and develop acreage in the Vaca Muerta. As a result, 2026 investment from private oil companies is expected to exceed $4 billion.Vista Energy, a pure-play shale producer which is the third largest producer in the Vaca Muerta, committed to investing $1.5 billion during 2026. Pluspetrol, the shale play’s fourth largest producer, plans to spend $800 million this year on its shale operations. The Vaca Muerta’s second largest oil producer, Pan American Energy, which lifted an average of 99,109 barrels daily for the first five months of 2026, has allocated $586 million for its 2026 capital expenditures.For these reasons, analysts expect Argentina’s oil production to reach one million to 1.5 million barrels of crude oil daily by 2030, while natural gas output will soar to over 6 billion cubic feet per day. Those numbers could be significantly higher if YPF’s $25 billion investment, via Buenos Aires’ Large Investment Incentive Regime (RIGI), to accelerate development of the Vaca Muerta is successful. Production constraints due to a lack of midstream infrastructure are being addressed with new pipeline and storage facilities under development. This will accelerate the Vaca Muerta’s development and the rate at which hydrocarbon output grows.By Matthew Smith for Oilprice.comMore Top Reads From Oilprice.comU.S. Refinery Utilization Hits 96.2% as Fuel Markets Tighten WorldwideLNG Importers Seek Lower Qatar and UAE Prices as War Upends DealsIndia’s Fuel Exports Set to Soar in July as Refining Margins Jump
