Abstract
Time-lapse (4-D) seismic analysis in Denbury Onshore LLC's Bell Creek Field, currently undergoing CO2 injection for enhanced oil recovery and associated CO2 storage, has illuminated a shale-filled permeability barrier and delineated local hydraulic connectivity between two development phases. From a CO2 storage perspective, the MVA program has benefitted through improvement to interpretation of 3-D seismic data, increased visibility of injected CO2, and identification of preferential fluid flow. Such efforts resulted in better history matching of dynamic models and increased accuracy of resulting predictive simulations. These knowledge gains may be used to ensure safe and secure storage at future CCUS projects.
