Along with horizontal drilling techniques, multi-stage hydraulic fracturing has improved shale
gas production significantly in past decades. In order to understand the mechanism of …

This article reviews the effect of weak interfaces on crack propagation in rock and some
other analogous brittle materials from phenomenon to mechanism. In this review, a variety of …

A new poroelastic damage model is developed in the paper to describe the macroscopic
failure of rock materials due to microcrack nucleation and propagation based on a multiscale …

Conventional discrete fracture network (DFN) modeling is used to simulate hydraulic fracture
propagation in fractured low permeability reservoirs. However, natural fractures have a …

Hydraulic fracturing treatment is one of the most efficient conventional matrix stimulation
techniques currently utilized in the petroleum industry. However, due to the spatiotemporal …

The propagation behaviour of hydraulic fractures is affected by natural fractures in
unconventional reservoirs and determines the effect of reservoir reconstruction to a certain …

Under the influence of tectonic stress and faults, there are many natural fractures (NFs) in
hot dry rock (HDR) reservoirs. However, the effect of NFs on the propagation of hydraulic …

Hydraulic fracturing (HF) is one of the most effective stimulation techniques to enhance
reservoir permeability. The efficiency of an HF fluid injection depends on the pre-existing …

With the extensive exploitation of fossil fuels, a substantial number of production and
injection wells have been or are on the verge of being abandoned. However, many of these …

Hydraulic fracturing operation as an effective enhancing coalbed gas production method is
widely used in ultra-low permeability coal seam. However, complex geo-stresses and high …
