Amerada Petroleum Corp., in Dec. 1966, completed a well in Section 31, Elk Township, Noble County, Ohio, to a total depth of 11,433 ft. This record depth hole led to the discovery of commercial oil production in the Ohio Shale. The Ohio Shale of the Upper Devonian consists of 3 members--the Huron, the Chagrin, and the Cleveland. The Ohio Shale crops out through the central part of Ohio from the Ohio River to Lake Erie. Well over half of the eastern part of the state is underlain by Ohio Shale as well as the Michigan basin portion of northwestern Ohio. The thickness of the Ohio Shale ranges up to nearly 3,500 ft. Some core samples have yielded a maximum of 12.5 gas/ton of shale oil. While this figure may not be overly impressive, past production histories from shale wells producing gas are more encouraging. An accompanying table shows meter-gas production compiled from wells that were drilled before hydraulic fracturing was introduced. From past history, wells completed in the Ohio Shale will have to be fractured to interconnect the natural fracture patterns with the well bore.
