TL;DR: In this paper, the authors developed a mathematical model to estimate the stimulated reservoir volume (SRV) through simulating the main process during shale fracturing, where multiple simultaneous hydraulic fractures propagate, perturbing the formation stress and raising the reservoir pressure; meanwhile, the stress change and pressure rise may jointly make natural fractures occur failure, and the SRV is estimated based on the volume of the naturally fractured zone that experiences tensile or shear failure.

TL;DR: In this article, the authors proposed a compelling cluster spacing optimization method, which could reduce the uncertainty in cluster spacing design, and provided some new insights on the optimal design of multi-stage fracturing in horizontal shale gas well.

TL;DR: In this paper, the authors analyzed the latest developments in such theories on the fields like fracture network fracability evaluation, fracture network propagation mechanism, stimulated reservoir volume (SRV) evaluation and fracturing fluid research & development.

TL;DR: In this paper, an integral mechanical coupling numerical model is established from staged fracturing on a horizontal well to analyze well shut-in and production, to simulate stress variation during the shutin period and the impact of shutin time on oil production.

TL;DR: Wang et al. as discussed by the authors comprehensively reviewed development history and status of domestic fundamental theories, optimized design methods, fluid systems, tools and technologies of shale gas fracturing and summarized the research results in fundamental theories and optimization methods, such as fracturing sweet-spot cognition, fracture network propagation simulation and control, rock hydration and flowback control.
