Argentina’s oil sector is experiencing a significant expansion fueled by the development of the Vaca Muerta shale formation located in Neuquén Province in northern Patagonia. In July 2026, the country’s total crude oil production reached 902,920 barrels per day, representing a record high and marking growth of 12% compared to the same period a year prior. Shale oil specifically accounted for 648,347 barrels daily in July, up 26% year-over-year and establishing an all-time high. This shale contribution now represents 72% of Argentina’s overall petroleum output, a record proportion. Natural gas output also expanded, with shale gas making up 70% of total production at 3.9 billion cubic feet daily in July.
The Vaca Muerta formation possesses geological characteristics that give it competitive advantages in global shale development. The formation features thicker shale layers, richer organic content, and higher reservoir pressure compared to many major North American shale plays, enabling wells to maintain productivity longer. Additionally, the formation boasts breakeven costs ranging from $36 to $45 per barrel, making it an attractive investment target. As conventional oil reserves in Argentina continue declining—with output 50% lower than a decade prior—unconventional shale development has become the primary growth driver for the nation’s hydrocarbon sector.
Major international energy companies are increasing investments in the Vaca Muerta. Chevron announced plans to invest $13.8 billion in developing its El Trapial acreage under Argentina’s Incentive Regime for Large Investments framework, which provides 30-year guarantees on regulatory, tax, and foreign exchange conditions. Continental Resources partnered with Phoenix Global Resources to bid on additional acreage during an August 2026 licensing round. Venture capitalist Peter Thiel acquired a 1% stake in Vista Energy, the region’s second-largest producer, for approximately $76 million.
State-controlled YPF, Argentina’s national oil company, is pursuing multiple major projects. The company submitted applications in August 2026 for a $51 billion integrated liquefied natural gas project developed in conjunction with Italy’s Eni and Abu Dhabi National Oil Company subsidiaries. Previously in May 2026, YPF announced a $25 billion investment plan targeting the LLL oil project, with production goals of 240,000 barrels daily by 2032. Industry projections indicate the Vaca Muerta formation could produce between one million and 1.5 million barrels daily by the end of the decade, solidifying Argentina’s position in global energy markets.
