PetroSA, or the National Petroleum, Gas and Oil Corporation of South Africa, is the country's national oil company. It owns, operates and manages the South African government's commercial assets in the petroleum industry. The company was registered in January 2002 as a commercial, non-listed entity under South African law. PetroSA is engaged in two worldwide businesses: oil and gas exploration and production; and the production and marketing of synthetic fuels and petrochemicals. The company explores for oil and gas in selected basins around the world, with a focus on Africa, and has producing fields off the coast of South Africa. It has marketing operations in the United States, Europe and the Far East that supply petrochemicals to customers in more than 40 countries. PetroSA is a pioneer in the field of gas to liquids (GTL) technology, recognised around the world for producing the cleanest fuels through an environmentally responsible process that releases minimal emissions. The company is responsible for producing and marketing synthetic fuels produced from offshore gas produced at its Mossel Bay refinery in the Western Cape, which is the world's largest commercial gas to liquids plant. PetroSA's gas-to-liquid plant supplies about 7 percent of South Africa's liquid-fuel needs. The products are supplied to oil companies that market them under their own brand names. PetroSA also produces anhydrous alcohols and speciality fuels that are exported and earn the company more than R500-million a year. PetroSA's oilfield, Sable, situated about 150km south off the coast of Mossel Bay, is expected to produce 17 percent of South Africa's oil needs. See the PetroSA website for more information.
