Dynamic Wettability Alteration in Immiscible Two-phase Flow in Porous Media: Effect on Transport Properties and Critical Slowing Down
The change in contact angles due to the injection of low salinity water or any other wettability altering agent in an oil-rich porous medium is modeled by a network of disordered pores transporting two immiscible fluids. We introduce a dynamic wettability altering mechanism, where the time dependent wetting property of each pore is determined by the cumulative flow of water through it. Simulati...
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...

A selection of these reports is available in PostScript form at the Faculty's anonymous ftp-Abstract We consider the one-dimensional two-phase ow including capillary eeects through a heterogeneous porous medium. The heterogeneity is due to the spatial variation of the absolute permeability and the poros-ity. Both these quantities are assumed to be piecewise constant. At interfaces where the roc...

متن کاملSteady-state two-phase flow in porous media: statistics and transport properties.
We study experimentally the case of steady-state simultaneous two-phase flow in a quasi-two-dimensional porous media. The dynamics is dominated by the interplay between a viscous pressure field from the wetting fluid and bubble transport of a less viscous, nonwetting phase. In contrast with more studied displacement front systems, steady-state flow is in equilibrium, statistically speaking. The...
