Fracture-permeability behavior of shale
WebAug 7, 2024 · Production simulation from fractured shale reservoirs is often performed by simplifying the hydraulic fractures as rectangular planes with homogeneous aperture. This study investigates the effects of heterogeneous fracture aperture and proppant distribution in realistic, non-rectangular fractures on the multi-phase production from shales. The … WebJan 1, 2024 · However, after most of the natural fractures have occurred failure under high-stress or high-pressure, shale permeability will turn to decrease as the stress continues to increase. This paper explores the inner mechanism and exterior behavior of shale permeability dependence on triaxial stress, pore pressure, and natural fractures failure.
