Founded in Dallas, TX, USA by Bill Clemens, who later became governor of the state, Sedco drilled for oil both in the USA and abroad, including maintaining a partnership with Zapata Off-Shore Company, where future American president, George H. W. Bush, acted as CEO. In 1958, Sedco branched to Iran, shortly after Prime Minister Mossadegh was imprisoned, and operated there until the Iranian Revolution in 1977.
