Fractured shale gas reservoir performance study--An offset well interference field test

Gas production characteristics of naturally fractured Devonian shale have been quantified through a three-well interference test using an established producing well and two offsets placed on the primary and secondary regional fracture trends relative to the producer. Three individual shale zones were tested simultaneously by buildup, drawdown, and pulse tests to investigate reservoir gas flow characteristics, natural fracture properties, and gas storage and release mechanisms. Test results show severe permeability anisotropy, indicating elliptical drainage pattern with an 8:1 axis ratio. Essentially all gas is stored in a sorbed state in the shale matrix and is transported toward the wells through the native fracture system.
