Abstract
A method is disclosed for monitoring the flood front movement during enhanced recovery operations wherein flooding fluids are pumped into a number of injection wells forcing residual oil movement toward a production well. A plurality of monitoring wells located between the injection wells and the producing well are logged to establish base logs functionally related to oil saturation and water salinity. Periodically during the water flood operation, the monitoring wells are relogged to detect changes in oil saturation and water salinity. By comparison of the base logs with the series of later derived logs it is possible to accurately monitor the flood front movement including detecting high-permeability zones and monitoring of the flood front profile.
