Funded by NETL under the American Recovery and Reinvestment Act of 2009, BEG-GCCC was subcontracted by Denbury Onshore, LLC to design and implement the Monitoring, Verification and Accounting (MVA) program for anthropogenic CO2 injected for enhanced oil recovery at West Hastings Field. The objectives of the program are (1) to document CO2 retention through a combination of novel MVA approaches and current commercial practices and (2) to evaluate the extent to which these commercial practices can meet possible future MVA expectations. The design of an MVA plan involves devising a monitoring strategy for elements and/or areas of identified highest risk of non-retention, not only within the injection zone (vertical migration), but also within the pattern (lateral migration). Previous CO2 EOR/storage studies such as Weyburn, SACROC, and BEG's Cranfield, have provided significant information for MVA design. We are utilizing this knowledge to design a targeted, commercial-scale MVA plan for West Hastings field.
