Water soaking a horizontal shale well is a practice whereby operators in shale gas and oil
production shut-in a well after a multistage hydraulic fracture treatment. By this practice, it is …

Imbibition is very common, occurring in life, material, chemistry, and energy. It plays an
important role in enhanced oil recovery (EOR). The development of many reservoirs is …

In petroleum engineering, imbibition is one of the most important elements for the hydraulic
fracturing and water flooding processes, when extraneous fluids are introduced to the …

Due to the low matrix porosity and permeability of gas shales, the horizontal well drilling and
hydraulic fracturing technologies become a necessity to exploit the unconventional shale …

Large volume water filtrates into the shale formation during multi-stage fracturing. The
influence of water imbibition to shale permeability, which still needs further investigation, is …

The potential for shale gas development and hydraulic fracturing to cause subsurface water
contamination has prompted a number of modeling studies to assess the risk. A significant …

Matrix and fracture permeability of carbonate rich tight cores from Niobrara, Bakken, and
Three Forks formations were measured before and after exposing the core samples to …

Hydraulic fracturing in shale gas formations involves the injection of large volumes of
aqueous fluid deep underground. Only a small proportion of the injected water volume is …

Tight sandstone is an important oil reservoir in China which development is required water
flooding. During water flooding treatments, imbibition is proven to strongly affect oil …

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 …
