Evaluating the brittleness of rock is significant for strategy determination of hydraulic
fracturing, such as candidate selection and parameter optimization. A series of definitions …

Unconventional resources like shale gas has been the focus of intense research and
development for two decades. Apart from intrinsic geologic factors that control the gas shale …

Multi-stage fracturing of horizontal wells to recover shale gas has attracted substantial
renewed interest in the physical and mechanical characteristics of shale. The mechanical …

Field monitoring of hydraulic fractures is currently expensive, and the recorded data is often
limited to reflect fracture networks, implying the necessity of utilizing additional evidence to …

Fracture geometry is important when stimulating low-permeability reservoirs for natural gas
or oil production. The geological layer (GL) properties and contrasts in in-situ stress are the …

Rock layering, a critical factor in determining fracture height growth, is pervasive in
Longmaxi shale formation in the southwest of China. This formation has characteristics of …

This paper mainly investigated the fractal characteristics of crack propagation in hydraulic
fracturing and the effect of fractal dimension of induced fractures on the rock breakdown …

Geothermal energy has been widely proposed as a potential renewable energy to replace
traditional fossil fuel energy. Hot dry rock (HDR) reservoirs were the main geothermal …

Weak bedding planes (interfaces), a critical factor in determining the fracture height growth
and the propagation pathway of the fractures, is pervasively distributed in the …

To investigate the impact of fluid viscosity and rock heterogeneity on the characteristics
(such as geometric complexity, roughness, and micro-morphology) of hydraulic fractures …
