What is the deepest occurrence of oil produced in West Virginia?
In the mid-1980s, some oil was produced from the Balltown sand of Upper Devonian age at a depth of approximately 2,900 to 3,200 feet in the Belington field in southern Barbour County. Some oil was produced from Devonian shales in northwestern West Virginia around the same time. A few wells produced oil from the Devonian Oriskany Sandstone at depths between 4,800 and 5,100 feet, and three wells produced oil from the Silurian Newburg sand at a depth of 5,500 to 5,800 feet.
