An efficient computation of leak-off induced poroelastic stress for a hydraulic fracture

This study investigates the problem of a hydraulic fracture propagating in a permeable formation with an emphasis on the computation of the poroelastic stresses caused by fluid leak-off into the formation. By using the assumption of smallness of the diffusion length scale relative to the fracture size, the three-dimensional poroelastic problem around the fracture splits into two simpler problems, one involving the undrained response due to...
