Empresa Nacional del Petróleo, or ENAP (English: National Petroleum Company) is a state owned company in Chile, based in Las Condes. The company is engaged in the exploration, production, refining, and marketing of hydrocarbons and their derivatives. ENAP was created by Law No. 9618, June 19, 1950. It was initially responsible for prospecting and exploiting oil in Tierra del Fuego and the Strait of Magellan, where deposits were discovered between 1945 and 1950.
Its subsidiary, ENAP Refinerías, operates three refineries: Aconcagua, Bío Bío, and Gregorio. The three have a total capacity of 220,000 barrels per day (35,000 m3/d), which represents all of Chile's refining capacity. These supply over 80% of Chile's fuels.
Through another subsidiary, ENAP Sipetrol (International Petroleum Company), founded in 1990, it has operations in Peru, Ecuador, Argentina, Iran and Egypt. International production is responsible for most of ENAP's crude oil supply, primarily from neighboring countries.
