1. A method for monitoring one or more formation fluids in a subterranean formation comprising:
disposing a bottom hole assembly into a wellbore;
measuring the one or more formation fluids in the subterranean formation with an electromagnetic (EM) measurement system disposed on the bottom hole assembly to form a first EM data set;
removing the EM measurement system from the wellbore;
inverting the first EM data set using an information handling system to form a first image of the one or more formation fluids in the subterranean formation;
disposing the bottom hole assembly into the wellbore a second time;
taking a second measurement of the one or more formation fluids in the subterranean formation to form a second EM data set;
inverting the second EM data set using the information handling system to form a second image of the one or more formation fluids in the subterranean formation; and
comparing the first image to the second image to identify movement of the one or more formation fluids in the subterranean formation; and
determining if a metal is disposed in the wellbore by reviewing the first image.
