SPE Latin America/Caribbean Petroleum Engineering Conference, 1994
Abstract The aim of this paper is to review the numerical simulation methods now being used for dealing with fluid displacement in porous media. One of them is the invasion percolation method, IP, which applies where capillary forces are dominant with respect to viscous forces at the fluid interface.

SIAM Journal on Mathematical Analysis, 1980
Laminar isothermal fluid flow of two immiscible compressible fluid phases in a porous medium is formulated in terms of four unknown functions $\rho _1$, $\rho _2$, $S_1$ and $S_2$ in a pair of partial differential equations \[ \frac{\partial } {{\partial t}}\left[ {\phi (x,t)S_i \rho _i } \right] = \frac{\partial } {{\partial x}}\left\{ {\kappa (x,t ...

Combustion Fronts in Porous Media
SIAM Journal on Applied Mathematics, 2002Summary: The equations governing combustion in situ in petroleum reservoirs are cast in a way that is appropriate to the study of the time asymptotic fundamental waves: rarefactions and shocks. The physical diffusion terms are maintained so that the internal structure of shocks can be analyzed.

This book introduces the reader into the field of the physics of processes occurring in porous media. It targets Master and PhD students who need to gain fundamental understanding the impact of confinement on transport and phase change processes. The book gives brief overviews of topics like thermodynamics, capillarity and fluid mechanics in order to ...

Nature, 1961
THE tortuosity, T, of a porous medium such as sandstone is a quantity that has been interpreted in various and sometimes conflicting ways, particularly its relation to porosity, ϕ, and formation factor, F (refs. 1–4). Tortuosity originally was understood to mean the square of the quotient average length of a flow-line divided by the net distance ...

Capillary rise in porous media
Physica A: Statistical Mechanics and its Applications, 2001Capillary rise experiments were performed in columns filled with glass beads and Berea sandstones, using visual methods to register the advance of the water front. For the glass bead filled columns, early time data are well fitted by the Washburn equation. However, in the experiments, the advancing front exceeded the predicted equilibrium height.

Annual Review of Fluid Mechanics, 1970
The problems of flow and transport in porous media present many fascinating challenges to students of mechanics: and it is surprising that, over the years, these questions have received relatively little attention at the Congresses and Symposia of IUTAM and of its predecessors.

Viscous fingers in porous media
Physical Review A, 1987We consider the formation of viscous fingers in porous media using the boundary-integral method with particular application to a recent experiment involving a Hele-Shaw cell filled with glass beads. When the less viscous fluid wets the beads we can account for the patterns as ordinary viscous fingers in the presence of large noise.

Regularized MPM for porous media
2023The present work deals with improving the Material Point Method (MPM) and its application to differential equations for modelling dry and saturated porous media. An adaptive regularization is proposed to improve the Moving Least Squares Approximation (MLS) in MPM, allowing improved results to be obtained even in the presence of unfavourable ...

Magnetohydrodynamic flows in porous media
Journal of Fluid Mechanics, 2002The aim of this work is to investigate the tensorial filtration law in rigid porous media for steady-state slow flow of an electrically conducting, incompressible and viscous Newtonian fluid in the presence of a magnetic field. The seepage law under a magnetic field is obtained by upscaling the flow at the pore scale. The macroscopic magnetic field
