Abstract
A method for estimating a displacement of a fluid-to-hydrocarbon interface in a reservoir in the earth includes: disposing an electrode in an injector borehole that is configured to inject a fluid into the reservoir; energizing the electrode with a voltage source to apply a voltage to the reservoir; disposing an electric field sensor in the injector borehole; disposing a gravity sensor in at least one of the injector borehole and a producer borehole that is offset a distance L from the injector borehole; injecting fluid into the reservoir; measuring a magnitude of a time-varying electric field due to the injecting using the electric field sensor to provide electric field measurements; measuring a magnitude of a time-varying gravitational field due to the injecting using the gravity sensor to provide gravitational field measurements; and estimating the displacement using the electric field measurements and the gravitational field measurements.
