Abstract
A closure mechanism and a method for plugging a flow control device of a well is provided. The closure mechanism includes a switch having a hollow interior and a U-shaped portion. The closure mechanism also includes a metal insert located within a portion of the hollow interior of the switch. The mechanism further includes a heating device positioned within the well. In the method, the heating device is activated in the well and melts at least a portion of the metal insert. The melted portion of the metal insert collects and re-solidifies within the U-shaped portion of the switch, thereby closing the switch and plugging the flow control device against flow.
