Coupled h-m fracture interaction using fem with zero-thickness interface elements [PDF]

, 2017
Intensive hydraulic fracturing is a procedure employed for low permeability reservoir stimulation. This technique consists of generating a sequence of regularly spaced parallel fractures (multi-stage fracturing). The generation of a fracture involves the

A model for discriminating the penetration propagation of hydraulic fractures considering the influence of injection parameters

Meikuang Anquan
Based on the theory of fluid flow and solid elastic deformation as well as the criterion of the propagation path when hydraulic fracture meets natural fracture, a model for the propagation of hydraulic fracture through layer is established in order to ...
