As a clean fossil fuel with great reserves, natural gas hydrate (NGH) is widely regarded as
an important future alternative energy source. NGH is widely distributed in onshore tundra …

As an emerging waterless fracturing technology, supercritical carbon dioxide (SC-CO 2)
fracturing can reduce reservoir damage and dependence on water resources, and can also …

Brittleness has a significant influence on rock failure under compression; however, the
mechanism is rarely comprehensively discussed. This study numerically investigates the …

In this paper, influential parameters on the hydraulic fracturing processes in porous media
were investigated. Besides, the simultaneous stimulation of solids, fluids and fractures …

The existing hydrate exploitation technology is characterized by low gas production in single
wells and a small exploitation range, owing to the low porosity and low permeability of …

A model capturing micro-void nucleation with tensile and shear failure modes is developed
to present interaction mechanism of propagating hydraulic fracture (s)(HF (s)) with shale …

Currently, the exploration of natural gas hydrates (NGHs) is regarded as a worldwide
research focus. Due to multiple characteristics of NGH reservoirs (such as weak bonding …

Depletion-induced stress change causes the redistribution of stress field in reservoirs, which
can lead to the reorientation of principal stresses. Stress reorientation has a direct impact on …

We present a unified criterion for cohesive modeling of fluid‐driven fracture based on the
dimensional analysis to simultaneously provide the constraint for cohesive element and time …

Directional rock rupture is an important and common problem in the engineering of rock
breaking. Directional rock rupture can be effectively achieved by linear collaborative …
