Standard Oil of Indiana

Amoco was a United States oil company formed from the dissolution of Standard Oil.

It was originally Standard Oil of Indiana, or Stanolind despite the fact that its headquarters was in Chicago, Illinois. Early operations centered on the Whiting, Indiana refinery. It sometimes still uses the Standard brand to sell oil in midwestern states. In 2001 the company merged with British Petroleum to form BPAmoco, which was later renamed simply BP.

Indiana Standard expanded from its midwestern roots by acquiring The American Oil Company (Amoco) along the eastern US coast and Pan-Am Petroleum in the southeastern US.
