Abstract/Summary Hydraulically Induced Fractures (HIF) are artificially created to improve the permeability of unconventional reservoirs. The interaction between rock and fluid makes it extremely difficult to fully predict the HIF growth in surrounding invaded zone. This study represents a novel method to model crack propagation in an intact rock under the action of forced fluid flow. The advantages of a 3D random voronoi grain-based models are discussed and compared with previous models. The ultimate goal is to suggest a procedure in order to improve the current models for HIF based on Three-Dimensional Distinct Element Code (3DEC). Consequently, a threedimensional voronoi tessellation is constructed and imported into 3DEC to model the process. The results show that as expected, in-situ stress components and injection rate are the controlling factors for direction and break down pressure, respectively.
