Abstract
An electric submersible pumping system includes a motor that is filled with motor lubricant fluid and a pump driven by the motor. The electric submersible pumping system further includes a fluid expansion module connected to the motor that is designed to accommodate the expansion and contraction of the motor lubricant fluid in the motor. The fluid expansion module preferably includes a piston seal housing in fluid communication with the motor and a bag seal housing in fluid communication with the piston seal housing. The fluid expansion module further includes at least one axially movable barrier in the piston seal housing and at least one expansible barrier in the bag seal housing. The axially movable barrier and the expansible barrier cooperate to permit the expansion of the motor lubricant fluid without contaminating the motor lubricant fluid with fluids or and solids from the wellbore.
