Modelling the propagation of waterflood induced hydraulic fractures

Conference · · Soc. Pet. Eng. AIME, Pap.; (United States)
OSTI ID:6638291
A mathematical reservoir model is presented to simulate the propagation of waterflood induced hydraulic fractures in a symmetry element of a waterflood pattern. The model consists of a conventional single phase reservoir simulator coupled with an analytical fracture model. The model is capable of simulating fracture propagation as a function of (1) injection and production rates or pressures, (2) reservoir and fluid properties, and (3) formation fracturing pressures. Examples are given that clearly bring out the characteristics of the hydraulic fracture growth. The key variables are the injection rate and the voidage replacement ratio. Fractures can be contained by restricting the injection rate and by imposing a voidage replacement rate equal to or less than one.
