Modeling Oil Recovery in Brazilian Carbonate Rock by Engineered Water Injection Using Numerical Simulation

Waterflooding remains the most commonly used method to improve oil recovery. Although injected brine type is mainly dependent on its availability, few of characteristics can be controlled during project design. Published laboratory work indicates that adjustment composition cause an increase in production by wettability alteration. This research objective propose a novel four-step framework for modeling improved recovery Engineered Water Injection from numerical simulation carbonate formations. We use geochemical-based model estimates contact angles predict The steps are (1) screening criteria, (2) geochemical evaluation, (3) alteration modeling, and (4) coreflood history-match. validate our conducting history-match simulations Brazilian Pre-Salt corefloods. Incremental factors between 5 11%, consistent with those reported experiments. reduction residual saturation varied 3 5%. new systematic procedure using comprehensive approach fundamental understanding underlying mechanisms Injection.
