The objective is to develop and optimize the High Energy Gas Fracturing (HEGF) technique to produce multiple fractures around a wellbore in order to stimulate natural-gas production in Devonian shale. A propellant-based fracture technology has been developed that permits control of pressure loading to produce multiple fracturing in a borehole. Experiments at Rowan County, Kentucky and Meigs County, Ohio, have transferred this technology, developed in ash-fall tuff at the Nevada Test Site (NTS), to Devonian shale. Results closely match the predictions of the semi-empirical model. A systems-analysis model has been constructed to evaluate the economics of HEGF. Tasks during the report period have concentrated on conducting HEGF experiments in Devonian shale, on further refinements to the finite-element model, on borehole-TV-image processing, and on initiating a cost-benefit analysis of HEGF stimulations in gas wells with measurable production. 8 references 7 figures, 3 tables.
