Abstract

Hydraulic fracturing is a process widely used to increase the reservoir permeability. High pressure fluid flow induces the propagation of a pressure front that stimulates rock flaws and locally densify the fracture Network. Realistic Discrete Fracture Networks (DFNs) must produce dynamic responses that match with natural dynamic data. This article presents our on going work that aims at characterizing the dynamic response of DFNs related to both the pressure front propagation and fluid flow. We particularly focus on the fracture aperture computation accounting for the fracture geometry and the stress states. Then, we discuss the definition of equivalent media for both the intact and the fractured rock before simulating the pressure front propagation using a fast marching method. Finally, we describe the discretization of fracture networks using a graph of connectivity to perform flow simulations in discrete fracture network.
