... Abstract Achieving reliable calibrations of hydraulic fracture geometries of half-length and height, as well as understanding natural fractures within the Sichuan Shale Gas Basin in Southwest China, is a formidable challenge. This is due to the pronounced stress heterogeneity and the intricate...

... Abstract In past studies, changes in fluid pressure in natural fractures (planes of weakness) have been ignored for the interaction of hydraulic and natural fractures. To overcome these limitations, in this paper we develop a method to simulate the growth of hydraulic fractures...
