Abstract
Integrating velocity measurements in a reservoir rock sample from the SACROC unit with an AVO proxy for subsurface supercritical CO2 has been reported. 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. The Permian Basin of western Texas and southeastern New Mexico is one of the largest hydrocarbon accumulations in the continental United States. Through the use of laboratory techniques combined with seismic analysis, CO2 can be monitored effectively in the subsurface. This technique has the advantage of being repeated as many times as needed, and it can track sequestered CO2 over a large area. This technique also can be combined with other methods, such as surface monitoring, VSP, isotope-based geochemical monitoring of water, and other methods to most effectively monitor sequestered carbon dioxide in order to minimize any potential impacts to the shallow subsurface from deep CO2 injection.
