The Department of Energy's (DOE) Eastern Gas Shales Program (EGSP) has focused primarily on the resource characterization of the Devonian shales in the Appalachian, Michigan and Illinois Basins, where the collective volume of gas in place is estimated to be on the order of 280 Tcf. From an early assessment of the petrophysical properties of these shales, attention now has turned to an understanding of the mechanisms controlling production of this unconventional-gas source. However, present knowledge of the production history of the Devonian shales is inadequate for an accurate estimation of the gas reserves, the optimum well spacing for gas extraction, and the preferred stimulation techniques to be used. As part of this program, a Deviated Well Test was designed to evaluate the spacing of natural fractures in the Devonian shale in Meigs County, Ohio as a follow-on test to further define shale production characteristics and to assess the benefit of additional section gained by drilling through the producing interval at the approximate angle for dip of 60/sup 0/ from vertical. The Columbia Gas Transmission Company, E.C. Newell 10056-D well, on the same site as a previous Off-Set Well Test, was selected for this investigation. This report summarizes drilling operations on this Deviated Well Test.
