Apache is an oil and gas exploration and production company with onshore and offshore operations in North America and in Argentina, Australia, Egypt, and the UK North Sea. The company has estimated proved reserves of more than 2.9 billion barrels of oil equivalent, mostly from five North American regions: the Gulf of Mexico, the Gulf Coast of Texas and Louisiana, the Permian Basin in West Texas, the Anadarko Basin in Oklahoma, and Canada's Western Sedimentary Basin. Royal Dutch Shell is Apache's largest customer, accounting for 15% of its oil and gas production revenues in 2010.
