Cuba Petróleo Union

The Cuba Oil Union (Spanish: Unión Cuba-Petróleo) or CUPET is Cuba's largest oil company. It is owned and operated by the Cuban national government. The company is involved in the extraction of petroleum deposits as well as the refining and distributing of petroleum products. In conjunction with the conglomerate CIMEX, it operates a chain of filling stations selling gasoline in convertible pesos.

The extraction is based in Cuba's northern region of Havana Province (Provincia de la Habana). CUPET jointly produces oil on the island and has business agreements with, among others, the People's Republic of China, the Spanish oil company Repsol and Canada's Sherritt International.

Cuba produces around 80,000 barrels per day (13,000 m³/d) of heavy crude oil. Various companies have explored for oil in Cuba over the last 15 years with the only new discoveries along the northwest heavy oil belt, an 80-mile (128 km) stretch of coast in La Habana and Matanzas provinces. Cuba consumes about 150,000 bbl/d (24,000 m³/d), of which 53,000 bbl/d (8,400 m³/d) of oil and oil products are imported from Venezuela on Petrocaribe generous financing terms under a wide-ranging cooperation accord.
