Abstract
Disclosed is an electric submersible pumping system for use in wellbore. The electric submersible pumping system includes a motor assembly, a pump assembly and a seal section disposed in the wellbore. The pump assembly is below the motor and is driven by the motor. The seal section is between the motor assembly and the pump assembly, and protects the motor assembly from thrust generated in the pump assembly. The seal section includes a shaft that transmits torque from the motor assembly to the pump assembly. A labyrinth chamber in the seal section restricts the flow of wellbore fluids. The seal section can also include a mechanical seal, a thrust bearing, a bag type chamber, an abrasion resistant bearing, and a motor electrical termination.
