In ARGENTINA and SPAIN, Repsol-YPF dominates the oil and gas sectors accounting for at least 50 percent of transportation, refining capacity, and gas stations in either country. YPF’s history goes back to the discovery of an oil field on Argentine government land in Comodoro Rivadavia in 1907. The Bureau of Mines operated the oil field until nascent oil nationalism in Argentina pushed for the creation of Yacimientos Petroliferos Fiscales (Fiscal Oil Fields) in 1922. General Enrique Mosconi, an ardent advocate of a state monopoly in oil, became its first director (1922 30). From this position, Mosconi promoted the creation of state oil enterprises in other Latin American countries, including MEXICO, where PEMEX would become a state monopoly in 1938. YPF never achieved monopoly status. Backpackers destinations 2016.
