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 ...

Improvement and effectiveness analysis of dynamic/static imbibition experiments. [PDF]
PLoS OneIn low-permeability fractured reservoirs, there is a generalized fluid displacement between the replacement fluid in the fracture and the matrix crude oil. This imbibition behavior plays a crucial role in the development of this type of reservoir.

Energies, 2020 In shale gas formations, imbibition is significant since the tight pore structure causes a strong capillary suction pressure. After hydraulic fracturing, imbibition during the period of shut-in affects the water recovery of flowback.

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 ...

A new slick water system for hydraulic fracturing in tight reservoir to enhance imbibition oil recovery [PDF]
E3S Web of Conferences, 2021 In order to give full play to the role of imbibition of capillary force and enhance oil recovery of ultralow permeability sandstone reservoir after hydraulic fracturing, the mixed water fracture technology based on functional slick water is described and

Imbibition of hydraulic fracturing fluids into partially saturated shale [PDF]
Water Resources Research, 2015 AbstractRecent studies suggest that imbibition of hydraulic fracturing fluids into partially saturated shale is an important mechanism that restricts their migration, thus reducing the risk of groundwater contamination. We present computations of imbibition based on an exact semianalytical solution for spontaneous imbibition. These computations lead to

Spontaneous imbibition in a slit pore: a lattice-gas dynamic mean field study [PDF]
, 2010 We present a theoretical study of spontaneous imbibition in a slit pore using a lattice-gas model and a dynamic mean-field theory. Emphasis is put on the influence of the precursor films on the speed of the imbibition front due to liquid mass ...

Effect of electroosmotic flow on brine imbibition in porous media
Water Science and Engineering, 2009 Based on Darcy's Law and the Helmholta-Smoluchowski equation, an imbibition velocity formula for the water phase with an electric field was deduced, showing that the imbibition velocity with an electric field is to various extents not only related to the
