YPF, short for Yacimientos Petrolíferos Fiscales, was founded in 1922 as the world's first state-owned oil company, created by the Argentine government to secure domestic fuel supply. For over a century YPF has been the backbone of Argentina's energy sector, and after privatization in the 1990s it was renationalized in 2012 with the state acquiring a controlling 51 percent stake. The company is today Argentina's largest integrated energy company, active across exploration and production, refining, petrochemicals, and fuel retail, and it has been at the center of the country's shale revolution, leading development of the Vaca Muerta formation, one of the world's largest reserves of unconventional oil and gas. YPF produces roughly 250,000 barrels of oil equivalent per day, with a growing share coming from Vaca Muerta shale, where the company operates more than 1,000 producing wells and has driven Argentina from net energy importer toward self-sufficiency. The company operates three refineries including the large La Plata complex near Buenos Aires, with total capacity of about 190,000 barrels per day, plus a petrochemical subsidiary, YPF Petroquímica, and a retail network of more than 1,500 service stations under the YPF brand. YPF is also building a leadership position in renewable diesel and lithium development in Argentina's northwest, aligning with the country's ambitions to become a key supplier of energy transition minerals. For B2B suppliers, YPF is the dominant buyer in Argentina's energy sector, procuring drilling rigs, casing and tubing, fracturing equipment, production chemicals, refinery catalysts, pipeline materials and oilfield services. Its Vaca Muerta development program, one of the most active shale plays outside North America, generates continuous demand for pressure-pumping equipment, sand, water infrastructure and well-completion technology, much of it sourced internationally. YPF runs public tenders under Argentine procurement rules, with growing local-content requirements that favor suppliers with Argentine manufacturing or assembly. For energy equipment and service companies seeking entry to South America's most promising unconventional basin, YPF is the essential partner.
