In 1891 members of an enterprise called the Utah Oil Company, whose incorporators included Simon Bamberger and C.J. Millis, sank a shallow well near the town of Green River, Utah. Not finding any oil, the company abandoned its well after drilling to a depth of 1,000 feet. During the remainder of the 1890s, oil and gas prospectors sank approximately twenty-five wells in various parts of the state.
