Abstract

An electric submersible pumping system (100) includes a motor (110) that is filled with motor lubricant fluid and a pump (108) driven by the motor. The electric submersible pumping system further includes a fluid expansion module (114) connected to the motor (110) that is designed to accommodate the expansion and contraction of the motor lubricant fluid in the motor. The fluid expansion module (114) preferably includes a piston seal housing (130) in fluid communication with the motor (110) and a bag seal housing (132) in fluid communication with the piston seal housing (130). The fluid expansion module further includes at least one axially movable barrier (134a, 134b) in the piston seal housing (130) and at least one expansible barrier (136) in the bag seal housing (132). The axially movable barrier (134a, 134b) and the expansible barrier (136) cooperate to permit the expansion of the motor lubricant fluid without contaminating the motor lubricant fluid with fluids or and solids from the wellbore.
