Understanding the impact of geostress on the failure mechanism of surrounding rock is
necessary for underground engineering applications. Here, we carried out a series of true …

Hydraulic fracturing in combination with horizontal well has been widely used to stimulate
shale oil and gas from reservoirs. Numerical simulation of hydraulic fracturing is a great …

The fracture network generated by hydraulic fracturing in unconventional shale reservoirs
contains numerous microfractures that are connected to macroscopic fractures. These …

The anisotropic shear strength of rough joints is examined from both experiments and
numerical simulations in this paper. The rough joints in the experiment are prepared by …

Quantitative characterization of the heterogeneity of shale mineral particles and
determination of the relationship between the heterogeneity and the anisotropy of shale …

The shale failure process and shale strength exhibit apparent anisotropic characteristics.
Due to limitations in experimental methods, studying the effects of heterogeneous mineral …

Hydraulic fracturing is a key technology for shale gas production. Activating the natural
fracture (NF) system in shale reservoirs and forming a complex fracture network can greatly …

Wellbore instability caused by the invasion of drilling fluids into formations remains a
significant challenge in the application of oil-based drilling fluids (ODFs). In this study …

Jurassic lacustrine shales containing kerogen types Ⅱ and Ⅲ are widely distributed in
sedimentary basins around the world. Previous studies on gas generation potential and …

Currently, Luzhou in the Sichuan Basin is a focal point for shale-gas exploration and
development in China. However, a lack of detailed research on the mineral composition of …
