Mobility and conformance control for carbon dioxide EOR–Part 1 ///
Over the past decades, the Department of Energy and its predecessor organizations supported a large number of laboratory and field research projects—including advanced reservoir characterization, mobility control and CO2-EOR flooding conformance—in an effort to improve the oil recovery process. DOE recently commissioned a CO2 mobility control and conformance control literature review to stimulate interest in developing advance technologies to overcome the geologic and process limitations of CO2-EOR. These limitations include poor sweep efficiency, unfavorable injectivity profiles, gravity override, high ratios of CO2 to oil produced, early breakthrough and viscous fingering.
