Modeling geomechanical properties of shales to make sense of their complex properties is
at the forefront of petroleum exploration and exploitation application and has received much …

Large volumes of water are used for hydraulic fracturing of low permeability shale reservoirs
to stimulate gas production, with most of the water remaining unrecovered and distributed in …

Understanding water uptake and drainage in shales has important implications for both
hydrocarbon extraction and hydraulic fracturing fluid disposal. This study reports gravimetric …

Predicting water imbibition into porous materials is important in a wide variety of fields, and
hydraulic fracturing of low permeability hydrocarbon reservoirs has emerged as an …

In this study, we review the concepts of capillary pressure and total suction. We propose that
for shales and siltstones, capillary pressure (matric suction) is not the only dominant source …

One of the popular EOR methods for unconventional oil reservoirs is taking advantage of the
spontaneous imbibition during the completion stage of a multistage hydraulic fractured …

The soil‐water characteristic curve (SWCC) plays an essential role in the analysis of the
shear strength, deformation, hydraulic conductivity, and aqueous diffusion of unsaturated …

Gas shales are fine-grained, organic-rich sedimentary geomaterials with ultra-low
permeability requiring hydraulic stimulation for gas extraction. Characterizing their water …

Capillary end effect (CEE) develops in tight gas and shale formations near hydraulic
fractures during flowback of the fracturing‐treatment water and extends into the natural‐gas …

The wettability of shale is critical for the development of shale oil and gas reservoirs. Due to
its complex composition, which includes organic materials and a number of different …
