Abstract
Official abstract text for this publication.
Downhole gravity measurements are used to monitor the volumetric sweep of CO 2 and estimate the fingering phenomenon if any. The gravity measurements have been found to be effective due to the high density contrast between CO 2 and 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 CO 2 flooding front and to predict the fingering phenomenon is used to provide a warning tool to improve the sweep efficiency, according to some embodiments.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for monitoring gas introduced into a subterranean reservoir comprising: a downhole gravity measurement tool adapted to be deployed in a borehole and to make gravity measurements at a downhole location; a processing system adapted and programmed to receive data representing the gravity measurements including horizontal gravity measurements from the downhole gravity measurement tool and based at least in part thereon to monitor parameters associated…
