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 …

The development of a fracture process zone (FPZ)(microcrack zone) ahead of a fracture tip
is a prominent fracture characteristic of rock-like materials. At present, understanding of the …

With the rapid development of horizontal well drilling and hydraulic fracturing techniques,
shale gas has become a major source of energy in recent years. However, accurately …

This paper presents a novel computational approach for modelling fluid-driven fracturing in
quasi-brittle solids using peridynamics. The approach leverages a rigorous coupling of the …

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 …

Separate-layer fracturing technology is one of the key stimulation technologies in the multi-
layer reservoirs However, multiple fractures cannot evenly propagate due to the strong …

The gas-tightness and stability of compressed air energy storage (CAES) cavern (usually
with three-layered struction of sealing layer, concrete lining and surrounding rock) plays an …

Hydraulic fracturing is one of the key technologies to stimulate oil and gas production in low-
porosity and low-permeability reservoirs. Thus, understanding the hydraulic fracture (HF) …

Hydraulic fracturing is widely used in the exploitation of shale gas reservoirs to create high
conductivity fractures and complex fracture networks. However, the low flowback efficiency …
