Tight gas formations bounded by base rock and/or overlain by an overburden rock, that are not barriers to vertical fracture migration, are not amenable to successful large stimulation treatments by hydraulic fracturing as practiced today. Reservoirs of this nature are abundant. The example considered is the North Douglas Creek Arch field, east of Rangeley, Colorado. This work presents the preliminary findings of a project sponsored by the Gas Research Inst. of Chicago and conducted by Terra Tek Inc. of Salt Lake City and Chandler and Associates of Denver. The program is aimed toward developing technology that can provide deeply penetrating fractures in formations lacking barriers to vertical migration. Four prospective techniques are being evaluated in the laboratory and in the field: fracture initiation placement (perforation placement), fracture packing with lightweight additives, controlled process zone fracturing, and electric heating/fracturing followed by hydraulic fracturing. 10 references.
