During spontaneous imbibition, a wetting liquid is drawn into a porous medium by capillary forces. In systems with comparable pore length and diameter, such as paper and sand, the front of the propagating liquid forms a continuous interface. Sections of this interface advance in a highly correlated manner due to an effective surface tension, which restricts front broadening. Here we investigate...

Spontaneous imbibition has been receiving much attention due to its significance in many subsurface and industrial applications. Unveiling pore-scale wetting dynamics, particularly upscaling the Darcy scale are still unresolved. In this work, we conduct image-based pore-network modeling of cocurrent spontaneous corresponding quasi-static imbibition, homogeneous sintered glass beads as well hete...

Recently, anomalous scaling properties of front broadening during spontaneous imbibition of water in Vycor glass, a nanoporous medium, were reported: the mean height and the width of the propagating front increase with time t both proportional to t(1/2). Here, we propose a simple lattice imbibition model and elucidate quantitatively how the correlation range of the hydrostatic pressure and the ...

The present paper discusses the theoretical studies involved in the development of the differential equations which describe the spontaneous imbibition of water by an oil-saturated rock. The basic assumption underlying in the present investigation is that the oil and water form two immiscible liquid phases and the latter represents preferentially wetting phase. The Saturation of injected water ...

During spontaneous imbibition, a wetting liquid is drawn into a porous medium by capillary forces. Recently, anomalous scaling properties of front broadening during spontaneous imbibition of water in Vycor glass, a nanoporous medium, were reported. The mean height and the width of the propagating front increase with time t both proportional to t. We argue that this anomalously large roughening ...

Steam-water flow exists in most geothermal reservoirs where steam-water capillary pressure plays an important role in controlling fluid distribution, transfer of liquid between fracture and matrix, well productivity, and even the reserves. However, it is very difficult to measure steam-water capillary pressure due to the phase transformation and the significant mass transfer between the two pha...

The wettability is a critical property that governs the in situ fluid distribution, fractional flow, and hydrocarbon trapping porous media. This topic of immense interest to petroleum industry for exploitation unconventional resources, which have become significant source oil gas production, especially North America, Canada, China, as result advancement horizontal drilling fracking technologies...
