Integrating velocity measurements in a reservoir rock sample from the SACROC unit with an AVO proxy for subsurface supercritical CO2

One of the most promising methods proposed to mitigate global [Formula: see text] and one that is useful in enhanced oil recovery is carbon sequestration, a process in which [Formula: see text] is pressurized and injected into geologic formations. A technical challenge surrounding the geologic sequestration of [Formula: see text] is tracking the movement of the fluids pumped underground. Monitoring, verification, and accounting activities related to [Formula: see text] storage are important for assuring that any sequestered [Formula: see text] 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 [Formula: see text] after injection.
