Gas EOR Project 8: Effect of CO2 Flooding on Asphaltene Precipitation and Wettability

Primary Investiagors: Kishore Mohanty, Quoc Nguyen

The goal of this project is to quantify the amount of asphaltene precipitation in a core due to CO2 or hydrocarbon injection and its effect on wettability of the rock. Cores of different lithology and oils of different asphaltene content will be considered. Wettability before and after CO2 flood will be measured. Wettability alteration will be correlated with asphaltene content and core heterogeneity.
