Abstract
Hydrocarbon wells and methods for identifying production from a region of a subterranean formation. The hydrocarbon wells include a wellbore extending within the region of the subterranean formation and a production tubular that defines a production conduit and extends at least partially within the wellbore. The hydrocarbon wells also include an electromagnetic transmitter, an electromagnetic receiver, and a controller. The electromagnetic transmitter is configured to provide an input electromagnetic signal to a region of the production conduit to electromagnetically excite a produced tracer material that forms a portion of a produced stream that flows within the production tubular. The electromagnetic receiver is configured to receive an electromagnetic output signal from the region of the production conduit. The controller is programmed to identify the region of the subterranean formation based, at least in part, on the output electromagnetic signal. The methods include methods of operating the hydrocarbon wells.
