ABSTRACT
Nine new oil fields and 8 new gas fields were discovered in Wyoming as a result of 195 new-field wildcats. Thirty-nine discoveries were made from the 284 total exploratory wells drilled. Major discoveries were oil in the Dakota and Minnelusa formations for new fields in the Powder River basin, oil from the Tertiary in the Wind River basin, and continued gas discoveries in the Big Piney-LaBarge area, and the Desert Springs and Wamsutter areas in the Green River basin.
The bulk of exploratory drilling for 1959 will probably be concentrated on (1) the eastern side of the Powder River basin drilling for Dakota and Minnelusa oil, and (2) in the Green River basin on the western flank and the east-central part drilling for gas.
The only well drilled in Idaho in 1958 was abandoned at 2,835 ft.
