Abstract

In this work, it is suggested numerically that it is possible to direct shear stimulation treatments in critically-stressed reservoirs. This would aid in the creation of Enhanced Geothermal Systems by promoting hydraulic connectivity in doublet-well systems. In this case, the stimulation treatment is directed using only the poroelastic stress changes associated with a previous stimulation treatment to precondition the stress field. This methodology is shown for reverse, strike-slip, and normal faulting stress regimes.
