Storage of carbon dioxide (CO2) through enhanced oil recovery (EOR) activities offers the dual benefit of increased oil production and storage of anthropogenic CO2. In the Illinois Basin, USA (the Basin), there are no commercial-scale CO2 EOR projects due to a number of obstacles, including the absence of a large-scale demonstration in the region and an economic supply of CO2. To address these issues, the Illinois State Geological Survey (ISGS) conducted a study to assess the potential for CO2 EOR at three strategically positioned fields in the Basin. The three fields-Assumption, Mattoon, and Forsyth-are located near two possible future sources of commercial CO2. The CO2 EOR of the three fields was evaluated through characterization of the reservoir architecture and simulation of CO2 EOR scenarios along with laboratory experiments to estimate the minimum miscibility pressure (MMP). The project provides site-specific estimates of CO2 EOR application and could serve as an impetus for larger demonstration projects in the near future.
