Using global characteristics of a centrifuge outflow experiment to determine unsaturated soil parameters [PDF]

open access: yes, 2011
Several centrifugation scenarios enabling the determination of soil parameters for saturated-unsaturated flow in porous media are presented, investigated, and discussed.

Effect of Water Distribution on Spontaneous Imbibition of Tight Rocks: A Fractal Approach

open access: yesEnergies, 2020
The original water distribution characteristic plays an important role in the fracturing liquid retention in actual tight reservoirs. In this paper, an analytical model was proposed to characterize the water distribution and its effect on the spontaneous

The prediction of spontaneous oil-water imbibition in composite capillary

open access: yesPetroleum, 2022
In view of the classical Lucas-Washburn equation, which can only describe the spontaneous imbibition of single wetted capillary, a tilted composite capillary model with circular cross section, composed of different wettability capillary wall was ...

Pipe network model for scaling of dynamic interfaces in porous media [PDF]

open access: yes, 2000
We present a numerical study on the dynamics of imbibition fronts in porous media using a pipe network model. This model quantitatively reproduces the anomalous scaling behavior found in imbibition experiments [Phys. Rev. E {\bf 52}, 5166 (1995)].

Switchable Imbibition in Nanoporous Gold

open access: yes, 2014
Spontaneous imbibition enables the elegant propelling of nano-flows because of the dominance of capillarity at small length scales. The imbibition kinetics are, however, solely determined by the static geometry of the porous host, the capillarity, and ...

A Generalized Capillary Imbibition Model for Porous Media in Tight Reservoirs

open access: yesAdvances 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 electroosmotic flow on brine imbibition in porous media

open access: yesWater 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

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

open access: yesFEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Effect of viscosity on oil recovery by spontaneous imbibition from partially water-covered matrix blocks

open access: yesEnergy Exploration & Exploitation, 2021
Spontaneous imbibition is an important mechanism of oil recovery from fractured reservoirs and unconventional reservoirs. Oil is produced by combining co- and counter-current imbibition when the matrix blocks was partially covered by water. In this paper,
