Abstract
Downhole gravity measurements are used to monitor the volumetric sweep of COand estimate the fingering phenomenon if any. The gravity measurements have been found to be effective due to the high density contrast between COand brine or oil which provides better and higher sensitivity. An analytical forward model is used to determine the location and shape characteristics of the flooding front. A strategy to monitor the movement of the COflooding front and to predict the fingering phenomenon is used to provide a warning tool to improve the sweep efficiency, according to some embodiments.
