CA 2250613

An oil-filled protector for use with an electric submergible motor, comprises a housing connectable to an electric submergible motor, and an oil-filled expandable chamber within the housing and in fluidic communication with the electric submergible motor. The expandable chamber is formed from an elastomeric material, and includes materials for preventing deleterious fluids, such as H2S, CO2 and CH4, from passing through the chamber and into the motor. Such materials include elastomeric materials with one or more metallic coatings or bonded layers. The chamber can include separate annular partitions to define an inner oil-filled region and an outer region filled with a barrier fluid that substantially inhibits the passage of the deleterious fluids.
