General Petroleum Corporation's well, Mabel West No. 1 (34-20-G), Center SE, NW, Sec. 20, T. 50 N., R. 92 W., Big Horn County, Wyoming, discovery well in the Manderson field, was completed in the Phosphoria limestone at a plugged back depth of 7,340. This well had penetrated the Madison at a total depth of 8,080. The well flowed from the Phosphoria, at an initial rate of 500 bbls./day of 37.1 gravity, brown oil, and a gas oil ratio of approximately 11,300. The gas contained 23.2 per cent hydrogen sulphide. The well is presently shut in and additional drilling deferred pending unitization of the area and development of facilities to process the hydrogen sulphide gas.

Maps are presented showing surface geology and structure. Characteristics of the Phosphoria producing zone are discussed.
