Book excerpt: Excerpt from The Basin and Greybull Oil and Gas Fields, Bighorn County, Wyoming The first of these structures to be successfully tested by deep boring is known as the Peay Hill anticline and is situated a short distance southeast of Greybull, Wyoming, at the junction of the Bighorn and Greybull Rivers. In July, 1907, the Peay Hill Oil Development Co. Obtained a high pressure gas well on the east bank of the Bighorn River, in Sec. 21, T. 52 N., R. 93 W., which, from its ability to maintain a strong, steady flow of gas for months without visible signs of diminution was the first good proof of the existence of appreciable quantities of gas, and possibly also oil, in these anticlinals.
