This project has developed and demonstrated a method to rapidly, cost effectively, and efficiently perform technical assessments of major engineering and scientific issues considered to be critical to the design, implementation, and operation of a saline aquifer CO2 storage sites and enhanced oil recovery operations. The research effort integrated well completion design, including effects of geomechanical stresses, into a static reservoir model coupled with reactive transport simulation. Model simulations enable CO2 storage sites assessment of geologic and fluid effects and factors on CO2 injection, capacity, and plume migration.
This project focused on the evaluation of various factors (e.g., heterogeneity, reactions, faults, seal integrity) affecting the characterization, design, and operation of saline aquifer storage sites. Improved characterization, design, and operation of saline aquifer sites reduce the risk of fugitive CO2 emissions and increase confidence in storage permanence. Specifically, this project evaluated factors affecting storage permanence using modeling, resulting in more cost-effective CO2 storage.
