TY  - JOUR
AB  - Fast synchrotron-based X-ray microtomography was used to image the injection ofsuper-critical CO2 under subsurface conditions into a brine-saturated carbonate sample at thepore-scale with a voxel size of 3.64µm and a temporal resolution of 45 s. Capillary pressurewas measured from the images by finding the curvature of terminal menisci of both connectedand disconnected CO2 clusters. We provide an analysis of three individual dynamic drainageevents at elevated temperatures and pressures on the tens of seconds timescale, showing nonlocalinterface recession due to capillary pressure change, and both local and distal (non-local)snap-off. The measured capillary pressure change is not sufficient to explain snap-off in thissystem, as the disconnected CO2 has a much lower capillary pressure than the connectedCO2 both before and after the event. Disconnected regions instead preserve extremely lowdynamic capillary pressures generated during the event. Snap-off due to these dynamic effectsis not only controlled by the pore topography and throat radius, but also by the local fluidarrangement. Whereas disconnected fluid configurations produced by local snap-off wererapidly reconnected with the connected CO2 region, distal snap-off produced much morelong-lasting fluid configurations, showing that dynamic forces can have a persistent impacton the pattern and sequence of drainage events.
