Title: Composite wellbore seal system with sensing and self-healing capabilities

Abstract

The present invention provides a self-healing wellbore seal system comprising a casing, a fiber reinforced polymer layer, and layer of polymer cement. The layers are bonded together and configured to create a low permeable and ductile seal at discrete locations of the wellbore or along the wellbore. The polymer layer may be chemically bonded to the casing and inhibits the formation of a microannulus at the casing. The polymer layer may be an aramid fiber reinforced polymer, a fiber reinforced polymer layer, or a glass reinforced polymer layer.
