Modeling method and hydraulic fracture propagation for jointed rock mass using PHF-LSM method

This paper presents a coupling procedure for modeling a jointed rock mass by the level set (LS) method and for simulating hydraulic fracture propagation by a permeability-based hydraulic fracture (PHF) model. The LS functions are developed to implicitly describe the spatial distribution of joints. These functions are integrated into the PHF model to simulate the behavior for six types of joint distributions. The presented PHF model is a smeared …
