Standard Oil Company of Iowa was created in 1885 as a subsidiary of the Standard Oil Trust to handle marketing along the Pacific Coast states of Idaho, Oregon, Washington, California, and Arizona.
 Though named for the midwestern state, it never included Iowa as one of its primary marketing areas.
 A prior company named Standard Oil of California had been formed in 1877, and was not associated with the Standard Oil Trust.
 In 1906, Standard Oil of Iowa was dissolved and its assets handed over to a new Standard Oil of California, later Chevron Oil Company, and now the Chevron Corporation.
 Standard Oil Company of Iowa is thus the original company that is now Chevron.

The Golden Gimmick refers to a foreign tax credit deal enacted in November 1950 by the US Government under president Harry Truman between King Ibn Saud of Saudi Arabia and the Arabian-American Oil Company (ARAMCO), a consortium comprising Standard Oil of California (Chevron), Standard Oil of New Jersey (Exxon), Standard Oil of New York (Mobil) and Texaco.
 King Ibn Saud was being influenced by Juan Pablo Pérez Alfonso of Venezuela who cut a similar 50/50 deal with New Jersey Standard Oil and Royal Dutch Shell.
 This 50/50 deal accorded the American oil companies a tax break equivalent to 50% of their profits on oil sales, with the other 50% to be diverted to King Ibn Saud via the US Treasury.
 The King agreed to this 50/50 splitting of Aramco's oil profits instead of nationalizing Aramco's oil facilities on Saudi soil.
 Venezuela eventually led the effort in forming OPEC and Saudi Arabia gained full control of Aramco by 1980.
