Abstract
Hydraulic Fracturing method was developed to increase the productivity of low permeability reservoirs. In this method, it is very important to predict the hydraulic fracturing geometry to ensure a safe and optimum design. Hydraulic fracture propagation is affected from natural discontinuities (fault, joint…) in fractured reservoirs. In this study, the interaction of hydraulic fracture with natural fractures and consequently the fracture propagation and variation of fluid pressure inside the hydraulic fracture is studied numerically. The numerical program (2DFPM) was developed based on combination of boundary element method (displacement discontinuity method (DDM)) and finite difference method (FDM). The validity of the numerical program was verified by KGD model. Different conditions of hydraulic and natural fracture interaction are modeled and the effect of natural fracture on distribution of fluid pressure profile along the hydraulic fracture length is studied. The results show that the interaction condition and injection parameters of fluid have more influence on the hydraulic fracturing method.
