AB: Success of geologic sequestration depends upon the vast majority of the injected CO2 to remain underground. However, buoyant forces will drive free phase CO2 vertically upward if any breaches exist in the caprock of the formation where CO2 is injected. Simulations of vertical migration of CO2 within caprock formations have been performed to determine the factors that affect the flowrate of the CO2 toward the surface, comparing the importance of the density of the CO2, the average fracture aperture, and the driving pressure within the formation. Integrating such information over a large area can give a prediction of an order of magnitude estimation of CO2 flux across a sequestration site.
