This article reviews laboratory experimental studies on hydraulic fracturing under triaxial and
true triaxial stress conditions in crystalline rock for geothermal purposes, and places …

Hydraulic fracturing techniques have been widely used to create complex fracture network in
unconventional reservoirs. The complexity of hydraulic fracture is significantly influenced by …

The influence of hydraulic fracturing on coal microfractures (10–1000 μm) is an important
part of the stimulation mechanism of coalbed methane (CBM) hydraulic fracturing, which is …

Rock cracking is of key concern to many geological applications. On a grain scale, rock
fracturing depends on not only the external load but also the mechanical properties of the …

In this paper, a new fully coupled hydromechanical model in terms of bond-based
peridynamics is proposed to simulate the pressured and fluid-driven fracturing process in …

The size, shape, and connection of pores in a coal seam after hydraulic fracturing
determines coalbed methane (CBM) production. To determine the variation characteristics of …

Propagation of hydraulic fracture (HF) in the presence of natural fracture (NF) fundamentally
differs with fracture propagation in reservoirs without natural fracture. Natural fracture can …

A true triaxial hydraulic fracturing system is built for carrying out fracturing stimulation
experiments on cubic raw coal specimens to simulate the hydraulic fracturing by means of a …

Hydraulic fracturing is one of the key technologies of shale gas extraction. Deeply
comprehending the distribution characteristics of hydraulic fracture networks in shale …

水力压裂是目前中国构建页岩油气储层复杂裂缝网络的主要技术之一, 而页岩储层内部矿物组分
差异以及不连续界面(层理, 天然裂缝) 的广泛分布使其具有强烈的非均质性 …
