Advances in CO2 Foam for Profile Control, Enhanced Oil Recovery, and Carbon Storage in Low-Permeability and Tight Oil Reservoirs
: Low-permeability and tight oil reservoirs are characterized by small pore-throat sizes and strong heterogeneity. During the process of conventional CO 2 flooding, viscous fingering, gravity override, and gas channeling through preferential flow paths are prone to occur, resulting in insufficient sweep efficiency, low...
