High Quality Content by WIKIPEDIA articles! Yacimientos Petrolíferos Fiscales (YPF, English: "Fiscal Petroleum Fields") was an Argentine state-owned oil company. Founded in 1922 under Hipólito Yrigoyen's administration, it was privatized in 1991 by Carlos Menem, and bought back by the Spanish firm Repsol, the result of the merger taking the name of Repsol YPF. YPF's first director was Enrique Mosconi, who advocated economic independence for Latin American states and, during Yrigoyen's second term, starting in 1928, nationalization of oil resources. The latter, however, was never achieved, due to a military coup headed in 1930 by José Félix Uriburu which overturned Yrigoyen.
