A workflow that uses the strain derived from geomechanical modeling of hydraulic fractures interacting with natural fractures is applied to a Fayetteville shale well. The derived strain map is used to estimate the asymmetric half lengths that are input in a frac design software able to incorporate this information. The usual symmetric bi-wing design is replaced by realistic asymmetric half lengths observed in microseismic data by adjusting the leakoff coefficient, injection rate and the proppant concentration in such a way that the asymmetric half lengths of the frac design do not exceed the lengths of those provided by the strain map. Once the half lengths and orientation from the frac design match those provided by geomechanical simulation, the propped length and other key results provided by the frac design software are used in reservoir simulation. The derived strain is correlated to stimulated permeability through two calibration constants estimated during history matching. After history matching, the resulting pressure distribution facilitates more informed selection of refrac or new well candidates, optimization of well spacing, and estimation of an accurate EUR.
