CO2 PENS

A conceptual and computer model for ensuring safe and effective containment of CO2

PREDICTING ENGINEERED NATURAL SYSTEMS

CO2-PENS is a software tool that links together physics-based process-level modules that describe the entire CO2 sequestration pathway, starting from capture at a power plant and following CO2 through pipelines to the injection site and into the reservoir. After injection, simulation of CO2 migration continues through the subsurface where it may mineralize, dissolve into brine, or react with wellbore casing or cement. CO2 may leak from the reservoir along wellbores or faults that lead back towards overlying aquifers or the surface. The model can be used to quickly screen sequestration sites or to perform a more detailed site-specific evaluation.
