Shale Matrix Petrophysical Evolution due to Spontaneous Water Imbibition. [PDF]

ACS Omega, 2023
Shale matrix alteration resulting from fracturing water-rock interactions has become a major concern. It significantly affects economic production from shale gas formation. Previous studies mostly failed to investigate the thickness of the water intrusion zone and quantified its effects on shale geophysical alteration.

Water imbibition and water sealing in water-driven gas reservoirs development

Energy Exploration & Exploitation, 2023
To improve the poor understanding of the mechanism of spontaneous water imbibition in water invasion in gas reservoirs and overcome the difficulty in quantifying imbibed water and its impact on reservoir development, a study is carried out based on ...

Deformation dynamics of nanopores upon water imbibition. [PDF]

Proc Natl Acad Sci U S A
Capillarity-driven transport in nanoporous solids is widespread in nature and crucial for modern liquid-infused engineering materials. During imbibition, curved menisci driven by high negative Laplace pressures exert an enormous contractile load on the porous matrix. Due to the challenge of simultaneously monitoring imbibition and deformation with high

Physicochemical mechanism of water phase imbibition in shale reservoirs [PDF]

Youqicang pingjia yu kaifa, 2023
Shale gas reservoirs, which develope micro-nano pore throats and fractures, have high clay mineral content, and strong heterogeneity of porosity. Therefore, large-scale hydraulic fracturing is usually needed to realize the effective exploitation.

Experimental Investigation of Spontaneous Imbibition of Water into Hydrate Sediments Using Nuclear Magnetic Resonance Method

Energies, 2020
Field observations show that less than one percent of dissociation water can be produced during gas hydrate production, resulting from spontaneous water imbibition into matrix pores. What’s more, the hydrate sediments are easily dispersed in water,

Microscopic imbibition characterization of sandstone reservoirs and theoretical model optimization

Scientific Reports, 2021
Traditional porous media imbibition models deviate from the actual imbibition process in oil and gas reservoirs. Experimental studies on gas–water imbibition in reservoirs were carried out to describe the dynamic profile variation process of wet phase ...
