The breakthrough of shale oil in North America led to a worldwide energy revolution. Shale
reservoirs show multiscale properties and a large proportion of nanopores compared to …

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 …

Chemical sand control is widely used due to its durability and cost-effectiveness. Injecting
polymers or nanoparticles into the reservoir can enhance its stability and prevent sand …

As a result of complex pore-throat geometry and precursor corner flow, the snap-off of the
non-wetting phase occurs during the spontaneous imbibition (SI) of wetting phase. However …

Nanofluids have been recently proposed as new chemical agents for enhanced oil recovery.
In this study, in order to reflect the effect of nanofluids on imbibition, the imbibition …

The contact between fracturing fluid and shale reservoir induces water-rock reactions such
as self-absorption, hydration damage, and ion diffusion, which leads to disturbed reservoir …

Large-scale hydraulic fracturing is the critical technology for effective shale oil production.
However, the imbibition flow mechanisms of fracturing fluid in shale micropores and the …

In the process of shale gas well drilling in the southern Sichuan Basin, China, lost circulation
of high-density oil-based drilling fluid has become a main challenge. In this study, a novel oil …

A shale gas reservoir is commonly characterized by nano-scale pores and throats, high clay
contents, and strong heterogeneity in permeability and porosity. Such tight structure can …
