Abstract:
An electric submersible pump assembly with integral heat exchanger, high-speed self-aligning bearings, and dual bearing thrust chamber is described. The described pump assembly, modules, and components may be used for operating an electric submersible pump at high speeds as well as over a wide range of speeds and flowrates without replacing downhole equipment. The described pump assembly may be shorter than comparable pump assemblies and may be assembled offsite, thereby leading to faster and easier installation with less down time. By operating over a wide range of speeds, the disclosed pump assembly allows the operator to reduce overall inventory, reduce down time for the well, and avoid other complications associated with replacing a pump assembly or other downhole components.

Claim (Index 5):
The motor of  claim 1 , further comprising an impeller, a central heat exchanger, and a lower heat exchanger, the impeller arranged to drive lubricant into the central heat exchanger;\n the central heat exchanger comprising a central exterior housing, a central interior housing, and a central lubricant return tube, wherein the central interior housing is disposed within the central exterior housing and defines a central heat exchanger lubricant pathway therebetween, and wherein the central lubricant return tube is disposed within the central interior housing; the lower heat exchanger comprising a lower exterior housing, a lower interior housing, and a lower lubricant return tube, wherein the lower interior housing is disposed within the lower exterior housing and defines a lower heat exchanger lubricant pathway therebetween, and wherein the lower lubricant return tube is disposed within the lower interior housing and is in fluid communication with the lower heat exchanger lubricant pathway; wherein the central heat exchanger is connected to the lower heat exchanger such that the central heat exchanger lubricant pathway is in fluid communication with the lower heat exchanger lubricant pathway and the central lubricant return tube is in fluid communication with the lower lubricant return tube.
