Abstract
The major oil and gas production in eastern Ohio is from the Berea sands and the "Clinton sands." In the Berea the controlling factors of accumulation of oil and gas are porosity and permeability trends, and not structure. In the "Clinton" the reservoir-controlling parameters are interstitial clay content, shale stringers and laminations, degree of cementing, grain size, pore geometry and thickness. Best production is from thick, more clay- and shale-free distributary-channel deposits and delta platform tidal channels. In northwestern Ohio, the major producing unit is the Trenton limestone. In the Trenton, accumulation is controlled by magnesium-carbonate content and structure. Best production is from true dolomite in structural traps on the northwest limb of the Findlay Arch. In north-central Ohio, the major oil production is from the Copper Ridge Dolomite. Here production is from the E and F members of the Copper Ridge Dolomite, present in erosional remnants on the Knox unconformity.
