Atlantic Richfield Company, otherwise known as ARCO, is a United States-based oil company with operations in the US, the North Sea, the South China Sea and Indonesia. Boasting over 1,300 gas stations in Western states including California, Arizona, Nevada, Oregon and Washington, ARCO is well known for its competitive gasoline pricing which is due to a decision made in the early 1980s to put precedence on cost cutting. Headquartered in La Palma, California, ARCO dates back to 1866, where it began as a company known as The Atlantic Petroleum Storage Company. It became part of Standard Oil Trust in 1874, but in 1911 the company achieved independence again when Standard Oil was broken up in. In 1966, the Atlantic Petroleum Storage Company, the name they had at the time, merged with Richfield Oil Company to create ARCO.
