Navigating the Path Forward in CO₂ Surveillance Utilizing Time-Lapse Seismic in Clastic Reservoirs

Denbury is actively applying 4-D seismic monitoring in several enhanced oil recovery (EOR) projects. Denbury’s portfolio of EOR floods mainly includes fluvial, variable permeability, variable porosity, clastic reservoirs at depths of ~3000ft-11000ft. The 4-D seismic response in these reservoirs is variable but predictable. The initial step in a successful 4-D seismic monitoring project is extensive source and receiver testing. The test data allows for planning the best possible seismic surveys. While seismic is king, the future of 4-D monitoring at Denbury will include investigating the feasibility of additional geophysical techniques for CO₂ monitoring. Denbury’s goal is, simply, to determine where the CO₂ is going and where it is not going.
