Historical NoteReturn to Top

The Union Oil Company of California (later known as Unocal) was founded in 1890. The Minerals Exploration Company was a wholly owned subsidiary of the Union Oil Company of California. In 1979, all of the company's energy mining operations (including the Minerals Exploration Company) were consolidated into the Union Energy Mining Division. The central region office of this division was based in Casper, Wyoming and was responsible for the exploration and acquisition of coal and uranium. Offices in Casper closed in the mid-1990s.

Content DescriptionReturn to Top

This collection contains coal exploration records from the Union Oil Company of California's Union Energy Mining Division office in Casper, Wyoming. Included are logs, correspondence, and reports pertaining to coal exploration, evaluation, and reserves. Exploration and evaluations in Colorado, Utah, Wyoming, Alaska, and North Dakota predominate; however, coal mining records include countries such as Australia and the Philippines, among others. Topographical maps from around the world, financial and administrative records, claims, reports, regulations, coal field evaluations, and title papers for properties are included. There is also a small amount of material on uranium mining. Some of these records (such as maps and memorandums) were created by other offices within the Unocal Corporation but pertain to the business and operations of the Casper office.
