Savia Perú S.A. is engaged in the exploration, production and marketing of oil and gas in Peru. Formerly known as Petro-Tech Peruana S.A., it was renamed in 2009 after it was acquired by Colombian company Ecopetrol and South Korean Korea National Oil Corporation (KNOC). Savia's onshore and offshore acreage in Peru totals 8.6Mha with a production of 14,500Boe/d of oil and gas. The company owns 11 blocks —two in operation and the rest in the exploration stage. In two operating blocks, Z-2B and Z-6, Savia has drilled four wells. The Lima-based company sells crude oil, natural gas, LPG and light aliphatic hydrocarbon.
