Numerical Investigation of Hydraulic Fracture Propagation in Naturally Fractured Reservoirs Based on Lattice Spring Model

Abstract: Hydraulic fracturing has been extensively employed for permeability enhancement in low-permeability reservoirs. The geometry of the hydraulic fracture network (HFN) may have implications for the optimization of hydraulic fracturing operations. Various parameters, including the in situ stress, treatment parameters (injection rate and fluid viscosity), and orientation of natural fractures (NFs), can significantly affect the interactions between hydraulic fracture (HF) and NFs and the final HFN. In this study, a … Show more

“…In particular, for some wells exploiting the Verey deposits a fracture of the pressure recovery curve was established, which is interpreted according to the Warren-Root model [22,23] as an effect on the flow of fracturing fluids of rocks. Generalization of information on hydrodynamic studies at the reservoir shows that the natural crack opening is quite low and does not exceed 10 μm.…”

“…The length and maximum width of the primary fracture show a decreasing trend, while the fracture volume also shows a decreasing trend. The total volume of hydraulic fractures decreased with increasing tensile strength of natural fractures, because the volume of fractures within the coal matrix produced per unit energy is smaller than that of hydraulic fractures extending within the natural fractures [31][32][33][34][35].…”

“…To model the hydraulic fracture, Jiang et al [26] proposed finite volume methods to discretize the flow equation and solved solid medium with cracks by the presented dynamic XFEM. Considering the permeability enhancement in naturally fractured reservoirs, Zhao et al [27] built the lattice spring model to indicate the effect of various influence parameters in the hydraulic fracture propagation. The XFEM and time integration were coupled by Haghani et al [28] to study the dynamic fracture of a cracked concrete dam interacted with the foundation and the reservoir.…”
