On the stimulation of geothermal reservoir by downward hydraulic fracturing
Fracture mechanics analysis of a vertically migrating hydraulic fracture is performed. The analysis concerns an elliptical crack subjected to fluid pressure acting on the crack faces and a far-field in situ stress, both varying linearly with depth. Predicted crack geometry is compared with a field result obtained from seismic mapping of the LASL hydraulic fracture experiment in the Jemez Caldera geothermal reservoir. The comparison reveals good qualitative agreement between predicted, and mapped crack geometries.
