Abstract :
This paper examines the effect of two types of surfactants (one nonionic and the other anionic) on wettability and multiphase flow characteristics by conducting contact angle measurements and flow tests through porous media using three different rock-fluids systems. The contact angle measurements have been made using the Dual-Drop Dual-Crystal (DDDC) technique and the multiphase flow characteristics are reported as oil-water relative permeabilities computed using a simulator by history matching the pressure drop and production data obtained during flow tests.
