Show The oil discovery currently cur-rently being tested in the Coalville vicinity is potentially po-tentially the most significant signi-ficant success of 1974 drilling activity in Utah and perhaps could lead to be one of the most important im-portant wells drilled in the state for quite some time. Largely because of the remoteness of the well, and its apparent success. ..now flowing at the rate of 35 barrels of oil an hour..., a whole new oil province reaching reach-ing from Coalville, northward through Morgan, Mor-gan, Weber, Cache and Rich counties to the Idaho Ida-ho state line as well as northeastward into Wyoming, Wyo-ming, is now under surveillance. sur-veillance. The discovery is in the Pineview area just east of Coalville. Geologically, it is loca- ted on the west fank ol the overthrust belt mthc southwestern reaches t the pi-eater Green River Basin where very little drilling has been done especially to comparable depths as the current well. While drilling, the well cut through a thrust fault in Triassic age formations for-mations and is bottomed in Cretaceous age formations form-ations at 14,500 feet. It was planned as a test of Madison formation of Carboniferous age Gust above the Devonian formation) for-mation) to approximately 17,500 feet and may yet be deepened. At this point, drilling costs have reached nearly two and a half million dollars. Oil flow is from the Nugget formation at a depth of 9,931 to 36 feet (a five foot perforated interval.) Geological data indicates at least a 140 foot section of apparently ap-parently productive sand. Nearest production from the Nugget formation forma-tion is some 100 miles to the northeast in Wyoming's Wyom-ing's Tip Top field near Big Piney. Utah's Brid-ger Brid-ger Lake field where oil is found at depths of 15,000 feet is more than 45 miles to the east. Evidence of a huge "lease-play" is now building. Petroleum Information In-formation Drilling report re-port shows approximately approximate-ly 60,000 acres of state and federal lands extending extend-ing from near the well, northward into Cache and Rich counties and on to the Idaho state line have been filed on by T.F. and W.L.
