One of the most promising methods proposed to mitigate global CO₂ and one that is useful in enhanced oil recovery is carbon sequestration, a process in which CO₂ is pressurized and injected into geologic formations. A technical challenge surrounding the geologic sequestration of CO₂ is tracking the movement of the fluids pumped underground. Monitoring, verification, and accounting activities related to CO₂ storage are important for assuring that any sequestered CO₂ does not escape to the surface and can be considerably aided by reflection seismic-based detection methods. Through the use of lab-scale velocity measurements under in-situ conditions, combined with multiple 3D reflection seismic surveys, we hope to effectively track the movements of CO₂ after injection.
