Carbon dioxide (CO2) is an attractive displacing agent for enhanced oil recovery. Because a large portion of the injected CO2 remains in place in depleted reservoirs after enhanced oil recovery, this method could also be an option for permanently sequestering CO2 to mitigate global warming. Los Alamos scientists and collaborators have developed a generic multi-scale statistical framework for CO2 accounting and risk analysis in CO2-enhanced oil recovery sites. This analysis method provides information to aid decision-making for applications of oil recovery and CO2 sequestration. Environmental Science & Technology published the research.
