How it started

History

Petronor was founded on November 30, 1968, with the participation of Basque bourgeoisie figures such as Javier Ybarra, Fernando Ybarra, Pedro Careaga or Alfonso de Churruca -the latter being the president of CAMPSA. The company was born with the aim of building an oil refinery in the north of Spain, after having received authorization to do so from the Franco regime. At the beginning of the 1970s, the shareholders of Petronor included Gulf Oil, Campsa, Río Gulf-Explosivos Río Tinto and several financial institutions in Biscay.
