Its founder and first director was Enrique Mosconi , who advocated economic independence and starting in 1928 , nationalization of oil supplies ; the latter , however , was never achieved due to a 1930 military coup against Yrigoyen backed by , among others , foreign oil interests . YPF was privatized in 1993 and bought by the Spanish firm Repsol S.A. in 1999 ; the resulting merger produced ' Repsol YPF ' . The renationalization of 51 % of the firm was initiated in 2012 by President Cristina Fernández de Kirchner . The government of Argentina eventually agreed to pay $ 5 billion compensation to Repsol
