In the shale gas extraction, drilling and hydrofracturing bring large amounts of water-based
working fluid into shale reservoirs, which much affects the wellbore stability and gas …

To understand the fluid-shale interactions and the mechanisms that produce cracks during
the retention of the fracturing fluid. This paper details experiments performed in shale …

The water-weakening effect is a significant cause of large deformations and damage in rock
engineering. In order to accurately describe the stress–strain relationship during the rock …

Spontaneous imbibition is a natural process in the interaction between liquid-rock and also
a vital influencing factor of hydraulic fracturing in shale gas exploitation. Currently …

Shale gas has enormous potential and has become a hotspot in recent decades. To exploit
shale gas, a variety of working fluids (drilling fluid, fracturing fluid, etc.) have to be applied in …

Borehole instability in igneous rock formation has attracted more and more attention in
recent ten years. In order to understand the mechanism of wellbore instability in igneous …

Previous studies have shown that water can reduce the acoustic emission (AE) energy and
other parameters during rock failure. However, the fracture mechanism of rock can be better …
