Role of Rock Mineralogy and Oil Composition in Wettability Alteration
$ 54.5
Description
Rock wettability alteration has been observed in carbonate formations but an integrated approach to address this phenomenon is lacking especially when CO2 is injected below its critical pressure. The effect of underlying factors such as oil composition and rock minerology behind wettability alteration are not well understood.
This study intends to fill this gap by investigating the influence of the crude oil/brine/rock system in the presence of subcritical CO2. The investigation will include polar interaction and surface precipitation. The study will also attempt to understand the most important combination of rock mineralogy and oil composition responsible for wettability alteration.
