Abstract: Methods, systems, and devices for characterizing an anomalous fluid body in an earth formation using measurements in a borehole intersecting the formation. Methods include galvanically exciting a transient electric field in the earth formation which interacts with an anomalous fluid body in the earth formation remote from the borehole; galvanically receiving a corresponding transient electromagnetic (TEM) signal; and using at least one processor to estimate a value of a parameter of the anomalous fluid body using the corresponding transient signal.
