ABSTRACT: Review of 1989 Oil and Gas Activities in Ohio

Michael P. McCormac

Oil and gas statistics for 1989 will be presented to reflect recent trends in permitting, drilling, production, and exploratory activities. The information will be presented both geologically and geographically.

A brief overview of the subsurface geology will orient the listener to the important producing formations in the state. As in previous years, the Silurian "Clinton" sandstone reservoirs were the most common drilling target. Recent drilling activities in the Ordovician Rose Run sandstone will be highlighted because of its current interest. As in 1988, exploratory drilling was concentrated in the Rose Run sandstone and Cambrian "Trempealeau" carbonates.

In 1989, wells were drilled in 43 of Ohio's 88 counties. Monroe County was the most active with 117 wells drilled.

There were several significant deep wells drilled in 1989. Highlights include the second deepest well ever drilled in Ohio (Washington County, 10,300 ft in the Rose Run sandstone) and the deepest well ever drilled in Monroe County (7507 ft in the Clinton sandstone).
