Investigation of Pressure Pulse Distribution in Porous Media
Diffusivity equation commonly used for pressure distribution prediction in porous media results from substituting equation of state and continuity equation in Navier-Stokes momentum equation. From mathematical point of view this equation format shows infinite propagation speed for pressure pulse through porous media, which is physically impossible. This issue may caused by numerous assumption...
متن کاملStabilizing fluid–fluid displacements in porous media through wettability alteration
We study experimentally how wettability impacts fluid–fluid displacement patterns in granular media. We inject a low-viscosity fluid (air) into a thin bed of glass beads initially saturated with a more-viscous fluid (a water/glycerol mixture). Chemical treatment of glass surfaces allows us to control the wetting properties of the medium and modify the contact angle θ from 5 deg (drainage) to 12...
متن کاملWettability Alteration Study for Two Phase Flow in Porous Media
Wettability of pores plays an important role in two-phase flow in porous media. In the case of oil recovery, it has been found from both laboratory experiments and field tests that deviation of reservoir wettability from strongly water-wet conditions either can increase or decrease in oil recovery efficiency which indicates a possible range of wettability change [1]. In this present work, the e...
متن کاملMultilevel Upscaling in Heterogeneous Porous Media
The multiscale structure of heterogeneous porous media prevents a straightforward numerical treatment of the underlying mathematical ow models. In particular, fully resolved ow simulations are intractable and yet the ne-scale structure of a porous medium may signiicantly innuence the coarse-scale properties of the solution (e.g., average ow rates). Consequently, homogenization or upscaling proc...
متن کاملTransient Fluid Flow in Heterogeneous Porous Media
A stable Alternating Direction Implicit finite-difference algorithm is used to model transient fiuid flow in heterogeneous porous media. In connection with the laboratory system for pressure transient testing of core permeability, the effects of permeability heterogeneities on the characteristics of the pressure transient were investigated. The results show that the early portion of the pressur...
