Abstract: The Plains CO2 Reduction (PCOR) Partnership, led by the Energy & Environmental Research Center, is working with Denbury Onshore LLC (Denbury) to characterize and monitor a large-scale CO2 enhanced oil recovery (EOR) and CO2 storage project at the Bell Creek oil field located in southeastern Montana, USA. Denbury owns and operates the field and will carry out the commercial EOR project. The PCOR Partnership is applying an integrated approach to site characterization, modeling, predictive simulation, risk assessment, and monitoring to improve understanding of the interrelationship between CO2 storage and EOR in a clastic reservoir.

Abstract: This simulation study evaluates ways for maximizing incremental oil recovery (IOR) and CO2 storage capacity for a current simultaneous enhanced oil recovery (EOR) and CO2 storage project at the Zama oil field F Pool situated in northwestern Alberta, Canada. The results clearly indicate the viability of formation water extraction for increasing storage capacity in a closed geological structure. An approximately fivefold increase in CO2 storage capacity was observed, if current EOR is coupled with bottom water extraction. IOR of 22.1% in the next 20 years can be achieved, which is 5% more than continuing current EOR without bottom water extraction. [Copyright &y& Elsevier]

Abstract: The Energy & Environmental Research Center has conducted an analysis of formation water extraction from carbon dioxide (CO2) storage reservoirs under joint sponsorship from the IEA Greenhouse Gas R&D Programme and the U.S. Department of Energy. The work included a survey of geologic and water quality conditions of deep saline formations, selection of four case study sites representing a wide range of these geologic and water quality conditions, and a study of the impacts of formation water extraction on CO2 storage and the potential for the beneficial use of extracted water at these sites.
