Counter-current 1D spontaneous imbibition in scaled form is investigated using Boltzmann transform before and after water meets the closed boundary (early late time). At early time system self-similar only depends on position divided by square root of time. it also interaction with no-flow hence a second variable, which set as Diffusion coefficients shifted to high saturations result spatial sa...

Imbibition phenomena have been widely used experimentally and theoretically to study the kinetic roughening of interfaces. We critically discuss the existing experiments and some associated theoretical approaches on the scaling properties of the imbibition front, with particular attention to the conservation law associated to the fluid, to problems arising from the actual structure of the embed...

Mixed wettability develops naturally on a pore scale in oil reservoirs after primary drainage. The invading fills interiors that become oil-wet by asphaltene deposition, while the residual water retreats into corners, masking them and retaining their wetness. This alteration hinders mobilization during secondary waterflood. Therefore, proper understanding of conditions controlling pore-scale im...

Water imbibition is a key factor affecting the flowback regime of shale gas wells after volume fracturing. In this study, set experimental apparatus and corresponding test evaluation methods were developed to analyze laws forcible water in reservoir, characterize initiation time microfractures induced by hydration quantitatively, optimize shut-in wells; depths different pore types are quantitat...

Tight oil and gas resources are widely distributed play an important role in the petroleum industry. Due to its nanoscale pore-throat characteristics, capillary effect is remarkable, spontaneous imbibition very beneficial development of low-permeability reservoirs. In this study, experiments 2D nano blackcard, nanoemulsion, water were carried out, respectively. The fluid distribution characteri...

Shale gas reservoirs are unconventional resources with great potential to help meet energy demands. Horizontal drilling and hydraulic fracturing have been extensively used for the exploitation of these resources. According engineering practice, some shale wells low flowback rate fluids may obtain high yield which is different from case conventional sandstone reservoirs, fluid absorbed into form...

The kinetics of development of protein-synthesizing capacity in the imbibing wheat embryo, were studied both in vivo and in vitro. During the first 30 minutes of imbibition protein-synthesizing capacity rises rapidly, lagging about 10 minutes behind water uptake. This rise in synthesizing capacity is accompanied by an increase in polysome content. As imbibition continues, both protein-synthesiz...
