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: A mechanical piping system and method is described herein. The system includes a first pipe with a first connection element disposed on an outer surface of the first pipe. The system also includes a second pipe with a second connection element disposed on an outer surface of the second pipe. An alignment element may also be included, with the alignment element creating a sealed flow path through the first pipe and the second pipe. Also, an external collar assembly may be included. The external collar assembly may engage the first connection element and second connection element and laterally secure the first pipe relative to the second pipe.

Abstract: An electrical submersible well pump assembly having a pump, a pump motor, and a seal section. The motor drives the pump via shafts rotatingly coupled with a coupling assembly. The coupling assembly includes an alignment device that maintains the shaft ends in coaxial alignment. The alignment device compressibly engages one or both of the shafts. The alignment device may be an elongated member having slots cut along its length on one or both ends configured to compress when inserted into a bore coaxially formed into the shaft ends within the coupling assembly.
