A Generalized Capillary Imbibition Model for Porous Media in Tight Reservoirs
Advances in Civil Engineering, 2018 Capillary imbibition models have been widely studied in oil and gas development field over the past decades. However, the existing models applied to the tight reservoirs rarely take fluid flow resistance and apparent viscosity into account.

Effect of Dynamic Imbibition on the Development of Ultralow Permeability Reservoir
Geofluids, 2021 To explore the methodology for improving ultralow permeability reservoir recovery, cores of ultralow permeability reservoirs in China’s Ordos Basin were selected to study the dynamic imbibition micromechanism of crude oil in nanopore throat through core ...

, 2007 When a very thin capillary is inserted into a liquid, the liquid is sucked into it: this imbibition process is controlled by a balance of capillary and drag forces, which are hard to quantify experimentally, in particularly considering flow on the ...

Critical conditions for the wetting of soils [PDF]
, 2006 The wettability of soil is of great importance for plants and soil biota and in determining whether flooding and soil erosion will occur. The analysis used in common measurements of soil hydrophobicity makes the assumption that water always enters soils ...

Interface pinning in spontaneous imbibition [PDF]
Physical Review E, 2001 Evaporation and gravity induced pinning in spontaneous imbibition are examined within a phase field formalism. Evaporation is introduced via a nonconserving term and gravity through a convective term that constrains the influx of liquid. Their effects are described by dimensionless coupling constants epsilon and g, respectively.

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
