ABSTRACT

The Bakersville Field in Adams Township of Coshocton County is one of Ohio's most significant Knox oil and gas producing fields to date. The field has produced nine bcf of gas to date, from the Beekmantown dolomite of the Knox Dolomite. The field was discovered in 1980 by Stone Resource and Energy (now known as NGO Development Corporation) when the Mizer #1 was drilled in Section 2 of Adams Township just a few thousand feet north of the town of Bakersville and an initial production rate of over one million cubic feet of gas per day (MMcf/d). The Mizer #1 has cumulative production greater than 2.8 billion cubic feet (bcf) and 8,700 barrels of oil (bo) as of May, 1994. Since the Mizer #1 was drilled a total of 33 wells have produced from the Bakersville field yielding an estimated 9.24 bcf of gas and 207,276 bo. The most interesting facet of the Bakersville field is that it remains the only known significant Beekmantown producing field in the now active Knox play of eastern Ohio. Several new discoveries are extending the potential of the Beekmantown as a oil and gas reservoir, but to date the Bakersville field is the only truly established Beekmantown producing oil and gas field in this state.

The Beekmantown reservoir is primarily a stratigraphic pinchout in what industry terms the "A" porosity zone. This "A" porosity zone most likely resulted from the dissolution of an evaporite layer deposited in a sabka environment. NGO Development Corporation (Stone Resource and Energy) has done extensive testing, coring, logging and seismic work to delineate the extent of the field and is currently working on a large three dimensional (3-D) seismic program to further identify drillable locations in the field. Core analyses, geophysical modeling and extensive geologic mapping has helped identify this field and can be used as a model for future Beekmantown exploration. NGO Development has graciously donated a large volume of information to the Ohio Department of Natural Resources, Division of Geological Survey. This data was used in cooperation with the Division of Geological Survey's DOE funded program to help extend the development of the Knox Dolomite including the Rose Run sandstone. This paper intends to show some of the past history of the field and cover the geologic and geophysical characteristics of the Bakersville field.
