A new model for fracturing fluid leak-off in a single natural fracture

Hydraulic fractures can open or penetrate natural fractures when naturally fractured oil and gas reservoirs are hydraulically fractured. Meanwhile, fracturing fluids enter the natural fractures, significantly increasing the leak-off volume. This paper proposes a new model of fracturing fluid leak-off in a single activated natural fracture, taking the deposition of solid-phase residues into account. The impact of leak-off on the viscosity of the...
