Salt Creek Oil Field

The Salt Creek Oil Field is located in Natrona County, Wyoming.

[2] By 1970, more oil had been produced by this field than any other in the Rocky Mountains region and accounted for 20 percent of the total production in Wyoming.

[3] Petroleum seeps in the area were known before 1880, but oil strikes near Lander led to claims by Schoonmaker and Cy Iba.

[6] The "gusher" well reached an oil sand after drilling through 1,000 feet (300 m) of shale.

[8] The field is on an anticline with 1,500 feet (460 m) of closure, which formed in the Late Cretaceous or Early Tertiary.
