Consolidated Royalty Oil Company.

The Consolidated Royalty Oil Company was organized in September, 1917 and headquartered in Casper, WY. Among the company's founders were B.B. Brooks (Ex-Governor of Wyoming), Clarence B. Richardson (a successful Cheyenne banker and oil operator), and Roderick N. Matson (attorney and judge from Cheyenne). The company acquired royalties and leases in oil and gas companies; it did not drill for oil. In 1917, the company purchased stock interest in the Stock Oil Company, the Royalty Oil Company, the Tisdale Royalty Company and about 90 percent of the Grass Creek Oil and Gas Company. Properties (oil fields) from these acquisitions included the Big Muddy Field, Salt Creek, Tisdale Oil Field, and the Grass Creek Field. Other royalty interests included Billy Creek, Wallace Creek, and acreage in California, Texas, Kansas, and Montana. Consolidated Royalty also owned the Consolidated Royalty Building (also known as the Oil Exchange building), a five-story office building in Casper. One of Consolidated Royalty's major subsidiaries was The Western Exploration Company, which was organized in January, 1917 and held a 50% interest in the Hudson Oil Company. In the 1960s, the company entered into liquidation which was completed by 1970.
