Yu, G. (author), Tang, J. (author), Li, L. (author), Rossen, W.R. (author)The main objective of this study is to understand the vertical sweep efficiency with miscible CO2-water-coinjection as a secondary recovery method, from multiple perspectives: phase behavior, total relative mobility, fluid densities/viscosities, the driving forces and consequent phase distributions etc. We also seek to provide insights into...conference paper 2023

Tang, Jinyu (author), Castaneda, Pablo (author), Marchesin, Dan (author), Rossen, W.R. (author)Foam is remarkably effective in the mobility control of gas injection for enhanced oil recovery (EOR) processes and CO<sub>2</sub> sequestration. Our goal is to better understand immiscible three-phase foam displacement with oil in porous media. In particular, we investigate (i) the displacement as a function of initial (I) and injection (J)...conference paper 2022

Tang, J. (author), Vincent-Bonnieu, S.Y.F. (author), Rossen, W.R. (author)We present a CT coreflood study of foam flow with two representative oils: hexadecane C<sub>16</sub> (benign to foam) and a mixture of 80 wt% C<sub>16</sub> and 20 wt% oleic acid (OA) (very harmful to foam). The purpose is to understand the transient dynamics of foam, both generated in-situ and pre-generated, as a function of oil saturation...conference paper 2019
