Abstract
A reinforced elastomeric bag for use within an electric submergible motor protector comprises a bag body formed from elastomeric material, such as fluoride co- and ter-polymers, butadiene copolymers, ethylene propylene diene methylene-based polymers, and combinations thereof; and a reinforcing material, such as tetrafluroethylene, aromatic p-polyamides, aromatic o,m-polyamides, fiberglass, ferrous metal, nonferrous metal, and combinations thereof. The reinforcing material is in the form of particles, threads and/or a weave that is dispersed within, bonded to or layered within the elastomeric material in a manner to improve the tear resistance of the bag at elevated temperatures encountered within wellbores.
