Evaporation of NaCl solution from porous media with mixed wettability

Stabilizing 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...

Wettability 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...

Multiscale Multiphysic Mixed Geomechanical Model for Deformable Porous Media Considering the Effects of Surrounding Area

Porous media of hydro-carbon reservoirs is influenced from several scales. Effective scales of fluid phases and solid phase are different. To reduce calculations in simulating porous hydro-carbon reservoirs, each physical phenomenon should be assisted in the range of its effective scale. The simulating with fine scale in a multiple physics hydro-carbon media exceeds the current computational ca...
