Geologic controls on gas production in the devonian shale, GRI Experimental Development Research Area, Pike County, Kentucky. Final report, January 1991-December 1992. Volume 1 of 2. Research report
Gas production from the Devonian Shale within the Experimental Development Research Area is controlled by its stratigraphic and structural framework. The main pay interval for the area are the black and gray shales of the Lower Huron and lower portion of the Chagrin (Transition Zone). Permeability and productivity within this interval is controlled by a variety of natural fracturing styles including regional jointing, flexure-related (density log) fracturing, and small-scale thrust faulting. The regional joint sets provide the basic permeability system for the reservoir, while these other features contribute to substantial increased productivity. Optimal completion zone selection requires the proper identification of these production-enhancing components in individual wells, and successful site selection should be based upon the definition of regions within an exploitation play which have the greatest likelihood of encountering these features.
