This report presents a detailed lithologic description of the Devonian Shale as observed in a core taken in Carroll County, Ohio. The cored well (Glen- Gery No. 5-745) is located in the southwest quarter of Section 29, Township 16M (Rose) Range 7, West Carroll County, Ohio. The purpose of the cored well is to characterize, in detail, the Devonian shale in Northeastern Ohio. Analysis of the cored material will provide information to be used in designing stimulation techniques for the improvement of gas production from the shale. The core data will be used to correlate stratigraphically these zones in a particular area of the Appalachian Basin. These high hydrocarbon zones in the shale will be stimulated by multiple-stage hydraulic fracturing in an effort to improve the rate of recovery of gas from the shale and to increase the amount of reserves assigned to a single well.
