... and cementation of the natural fractures (NF) ( Laubach and Gale, 2006 ) and are heavily driven by stress anisotropy. The DR pattern is a recreation of the interaction between the natural and induced fractures. It assumes that the hydraulic fracture will reactivate along the natural fracture extending to its...

Taking this concept a step farther, actual hydraulic fracture propagation will interact with natural fractures, localized stresses, and each other, creating an even more complex and hydraulic fracture geometry. Presented here is a novel application where the coupling of RTA and numerical...

... is applied to unconventional reservoirs with hydraulic and natural fractures. Our approach relies on cell volumes and connections (transmissibilities) rather than the grid geometry, and thus can be easily applied to complex grid systems. For illustrative purposes, we present applications of the proposed...
