Developments in Rocky Mountain region in 1942

Drilling activities in the Rocky Mountain region on the basis of wells making footage were 83 per cent in number and made 87 per cent of the footage of 1941. Oil and gas production increased about 8 per cent. Discoveries in Wyoming were more important than any since 1938, with the completion of large oil wells in the previously untested Tensleep sandstone at Elk Basin, and Pilot Butte; Lakota, and possibly Muddy sand oil production at Horse Creek; gas wells at Sherard; and other lesser discoveries. Minor discoveries were made in Montana. Prospecting in Colorado, North Dakota, South Dakota, northwestern New Mexico, and Utah was less successful. Extensions of known fields were not important in developing new reserves. The number of wildcat wells in operation declined 25 per cent. Pipe-line activity consisted of a few extensions, replacements, and short gas lines.
