Imbibition: Experiment and simulation

Physica A: Statistical Mechanics and its Applications, 1996
Abstract We report an imbibition experiment in 2D random porous media where the height-height correlation function grows with an exponent which depends on evaporation. We present an imbibition model consistent with this result.

Estimation of Imbibition Capillary Pressure Curves from Spontaneous Imbibition Data

Energy & Fuels, 2009
A closed-form solution for calculating imbibition capillary pressure from experimental data has been derived on the basis of the assumption of a constant capillary diffusion coefficient combined with Corey functions for the relative permeability curves. The solution is almost similar to the capillary pressure correlation reported by Skjaeveland et al. (

Imbibition of Surfactant Solutions

SPE Advanced Technology Series, 1993
ABSTRACT The goal of dilute surfactant flooding is to reduce the interfacial tension of the oil/water system to very low values in order to release the residual oil. The question then arises whether oil that would normally be produced by imbibition is lost as a result of such flooding; since the surfactant decreases or eliminates the ...

Spontaneous Imbibition and Imbibition Oil Recovery in Tight Rocks

2017
Advances in the development of unconventional resources have led to a surge in North American oil production. For example, tight oil production has pushed the U.S. crude supply to over 9% of world total production. Therefore, petrophysical characterization of such low-permeability rocks, has become increasingly important for petroleum engineers ...

Polymer Imbibition Through Paper Strips

Langmuir
Liquid wicking and imbibition through porous strips are fundamental to paper microfluidics. In this study, we outline these processes via capillary rise dynamics (CRD) experiments by employing deionized water as a reference fluid and comparing its dynamics with those of aqueous polymer solutions.

Interface dynamics in imbibition

AIP Conference Proceedings, 2000
We address the propagation and kinetic roughening of a liquid-gas interface moving through a disordered medium under the influence of capillary forces. The system is described by a phase-field model with conserved dynamics, and spatial disorder is introduced through a quenched random field.

Storage, Imbibition, and Germination

1985
Considerable controversy has surrounded the claims that seeds remain viable for many hundreds or even thousands of years. A list of some of the more spectacular claims is presented in Table 3.1, along with reasons for accepting or rejecting them. Perhaps the most persistent myth concerning seed longevity is that viable grains of wheat and barley were ...

Imbibition, Leakage and Membranes

1983
The process of imbibition is accompanied by a variety of other events—the activation of enzyme systems, the start of active metabolism and the leakage of solutes. The intention of this chapter is to present the facts about water uptake and leakage briefly, and then attempt a critical review of some of the interpretations that have been proposed.
