YPFB Andina, formerly Empresa Petrolera Andina, is an E&P subsidiary of Bolivia's state hydrocarbons company YPFB. It is involved in the areas of oil and gas exploration, production, distribution and sales. It is the largest hydrocarbon producer in the country, supplying nearly 40% of Bolivia's natural gas and more than 32% of the country's crude and condensed oil and gasoline production. In 2008, Bolivia's government took majority control of YPFB Andina from Spanish oil major Repsol YPF as part of efforts to nationalize the country's hydrocarbons sector. Andina is managed by a public-private partnership; the Bolivian government has a 51% stake and Repsol YPF-Bolivia owns 48.33%. The company has interests in 21 areas (18 as operator and three as strategic partner). YPFB Andina also holds a non-operating interest (50%) in fields San Antonio and Alberto through a consortium formed with Petrobras Bolivia (35%) and Total E&P Bolivie (15%).
