Abstract
A method for determining the activation of an expandable sand screen may comprise disposing an electromagnetic (EM) detection tool into a wellbore. The EM detection tool may comprise at least one transmitter and at least one receiver. The method may further comprise transmitting an EM field from the one or more transmitters into the expandable sand screen to energize the expandable sand screen and form an eddy current, recording a voltage of the eddy current with the at least one receiver, and determining an activation state of the expandable sand screen based at least partially on the voltage of the eddy current.
