A method for operating an electric submersible pumping system includes the steps of operating the electric submersible pumping system until it reaches a steady state operating condition, obtaining a first internal motor temperature measurement, obtaining a first external motor temperature measurement, and determining a first temperature differential based on the difference between the first internal motor temperature measurement and the first external motor temperature measurement. The method continues with the steps of obtaining a second internal motor temperature measurement, obtaining a second external motor temperature measurement, and determining a second temperature differential based on the difference between the second internal motor temperature measurement and the second external motor temperature measurement. Next the method includes the steps of comparing the second temperature differential to the first temperature differential, and indicating a probability of scale accumulation on the electric motor if the second temperature differential is greater than the first temperature differential.

Method for detection of scale on ESP using differential temperature measurement

A fixture has a body that connects to a motor, the body having a bore. The body has a piston in the bore, separating the bore into a pressure chamber and a lubricant chamber in fluid communication with lubricant in the motor. A technician applies pressure to the pressure chamber, which causes the piston to increase pressure of the lubricant in the lubricant chamber and in the motor. The technician monitors a distance of movement of the piston, indicating a presence of residual air in the lubricant. If the movement meets a amount, the technician applies a vacuum to the lubricant chamber and bleeds out residual air from the lubricant in the motor.

Method and apparatus for testing for and removing trapped air from submersible well pump assembly

An electrical submersible well pump assembly has a SAW (surface acoustic wave) sensor on a motor shaft. A SAW electronic circuit mounts to the motor housing. The SAW electronic circuit has an antenna closely spaced to the SAW sensor for monitoring torque on the motor shaft. A controller at an upper end of the well supplies power to the motor. A motor gauge unit mounted to a lower end of the motor transmits signals to the controller. A signal line extends from the SAW electronic circuit to the motor gauge unit for transmitting signals from the SAW electronic circuit to the motor gauge unit, and from the motor gauge unit to the controller.

Torque monitoring of electrical submersible pump assembly

An electrical submersible well pump (ESP) has a motor electrical connector mounted to an exterior of the motor. A motor sensor connects to an interior side of the motor electrical connector. Seal first and second electrical connectors mount to an exterior of a seal/motor adapter. A seal internal wire within the seal section electrically connects interior sides of the seal first and second electrical connectors together. An external motor jumper wire extends alongside the motor between the motor electrical connector and the seal first electrical connector. A pump electrical connector mounts to an exterior of a pump/seal adapter and connects to a pump sensor within the pump. An external seal jumper wire connects between the seal second electrical connector and the pump electrical connector.

Data and power configuration for electrical submersible well pump

A seal section of a submersible well pump assembly has an expandable and contractible bag surrounded by a pressure equalizing chamber. A motor lubricant communication path communicates motor lubricant the bag interior. A well fluid port admits well fluid into the pressure equalizing chamber. A gas vent passage leads from the pressure equalizing chamber to the exterior of the enclosure. At least one membrane in the gas vent passage allows gas contained in the well fluid in the pressure equalizing chamber to vent. The membrane blocks liquid from flowing through the gas vent passage into and out of the pressure equalizing chamber.

A submersible pump assembly includes a seal section connected to a motor, the seal section having a housing with an outboard bearing at a housing pump end in radial supporting engagement with a drive shaft. An inboard bearing is also in the housing pump end, axially spaced from the outboard bearing, and in radial supporting engagement with the shaft. A barrier fluid chamber in the housing pump end contains a barrier fluid. A primary shaft seal is located within the barrier fluid chamber and seals the barrier fluid in the barrier fluid chamber from the motor lubricant. A secondary shaft seal is mounted in the barrier fluid chamber between the primary shaft seal and the outboard bearing. The secondary shaft seal seals the barrier fluid in the barrier fluid chamber from well fluid exterior of the housing pump end.

A submersible well pump assembly has a communication path for communicating motor lubricant to an interior of a pressure equalizer. A check valve passage with a check valve leads from the communication path to a pressure equalizing chamber. A dip tube has a dip tube inlet at the check valve passage below the check valve and a dip tube outlet in the pressure equalizing chamber. The dip tube is filled with motor lubricant to retard migration of well fluid from the pressure equalizing chamber into contact with the check valve.

A well pump electrical motor has a motor housing filled with a dielectric motor lubricant. A motor head has at least one motor lead passage in fluid communication with the motor lubricant. An outer seal, which is exposed to well fluid, seals around a motor lead in the motor lead passage. An inner seal seals around the motor lead in the motor lead passage inward from the outer seal and has an inner side in contact with the motor lubricant in the motor. A barrier fluid passage extends into an annular space between the inner and outer seals and contains a barrier fluid. A pressure compensating device has an inner side in contact with the barrier fluid in the barrier fluid passage for reducing a pressure differential between the barrier fluid and a hydrostatic fluid pressure of well fluid on the exterior of the motor.

Pressure compensated motor power lead connection for submersible pump

An electrical submersible well pump assembly includes an electrical motor for driving a pump. A pressure compensating chamber contains a dielectric lubricant in fluid communication with an interior of the motor. A movable pressure compensating element has a first side in contact with the lubricant in the chamber. Movement of the element relative to the chamber causes a change in volume of the chamber. An electrical drive mechanism is connected with and moves the element. A controller senses a pressure difference between the lubricant pressure and the well fluid pressure and operates the drive mechanism in response. The element may be a piston, a bellows or telescoping tubes.

A well pump seal section housing connects between a pump and a motor. Upper and lower retainers at upper and lower ends of the housing have outward facing cylindrical walls. A bladder has an interior in fluid communication with dielectric lubricant in the motor. Rigid upper and lower sleeves are bonded within upper and lower openings of the bladder. The sleeves slide over the cylindrical walls of the retainers and are sealed by seal rings. Fasteners secure the sleeves to the cylindrical walls.

A well pump assembly includes a centrifugal pump having a housing with a cylindrical internal side wall. Upper and lower diffusers are located in the housing. A metal-to-metal seal seals an upper end portion of the lower diffuser to the lower end portion of the upper diffuser. The seal also has an outer surface that frictionally engages the internal side wall of the housing. The seal is energized in response to an axial force exerted between the upper and lower diffusers. One version has a metal seal ring located in mating recesses on the outer walls of the diffusers. Another version includes an inner lip on one of the end portions of the diffusers that extends within and deflects an outer lip on the other of the end portions of the diffusers.
