Abstract: A stator assembly for an ESP. The assembly can include stators with tabs and corresponding slots that prevent rotation of the stators during use in downhole activities.

Abstract: An electric submersible pump assembly with integral heat exchanger, high speed gas separator, high-speed self-aligning bearings, and dual bearing thrust chamber is described. The described gas separator 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.

Abstract: An electric submersible pump assembly with upthrust protection 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.

Abstract: Methods and systems for pumping a production fluid from a production zone to a collection point are described herein. The methods generally include disposing a tubing in the production zone of a wellbore; pumping the production fluid from the production zone through a first stage of a pumping system to achieve an inter-stage pressure sufficient for entry into a second stage; and pumping the production fluid at the inter-stage pressure through a second stage of the pumping system to achieve a lifting pressure sufficient to lift the production fluid to a collection point, wherein the second stage includes a jet pump.
