We use the Mason-Morrow shape factor, i.e., a dimensionless hydraulic radius, and corner half-angles to capture the geometry of noncircular capillaries pertinent to a physically adequate pore networkâ€¦ (More)

Traditional mathematical models of multiphase flow in porous media use a straightforward extension of Darcyâ€™s equation. The key element of these models is the appropriate formulation of the relativeâ€¦ (More)

Gases typically display large flow mobilities in porous media relative to oil or water, thereby impairing their effectiveness as displacing fluids. Foamed gas, though, is a promising agent forâ€¦ (More)

FOllin is an excellent fluid for achieving mobility control of gas in porous media. Practical application of fOllins for EOR processes, however requires a predictive model of foam displacement.â€¦ (More)

We present an integrated approach to imaging the progress of air displacement by spontaneous imbibition of oil into sandstone. We combine Computerized Tomography (CT) scanning and neural networkâ€¦ (More)

In Part I of this paper, we introduced the Mason-Morrow shape factor and the corner half-angles to capture the part of geometry of angular capillaries essential in pore network calculations ofâ€¦ (More)

We present a multiscale formulation for the numerical solution of one-dimensional three-phase flow through porous media. In the case of vanishing capillarity effects, the system of equationsâ€¦ (More)

The main objective of this work is to obtain a simplified asymptotic representation of the reflection of seismic signal from a fluid-saturated porous medium in the low-frequency domain. In the firstâ€¦ (More)

Reflection of a seismic wave from a plane interface between two elastic media does not depend on the frequency. If one of the media is poroelastic and fluid-saturated, then the reflection becomesâ€¦ (More)
