GEOLOGIC FRACTURING METHOD AND RESULTING FRACTURED GEOLOGIC STRUCTURE

摘要

In one exemplary approach, fracturing an underground geologic formation along a section of an underground bore hole is accomplished by positioning plural spaced apart charges along a section of the bore hole. These charges can comprise plural spaced apart non-ideal high energy explosive charges and/or propellant charges. One or more containers of inert material such as brine or liquid lower density explosives can also be included in a string of spaced apart charges, such as intermediate to such charges. Detonation of the charges can be simultaneous or independently timed. The charges are desirably configured to produce a unique underground fractured rock structure comprising rubblization zones along the section of the bore hole that include spaced apart zones extending, such as in disc-like fashion, radially outwardly a greater distance than the radially outwardly extending distance of rubblization zones between the spaced apart zones.
