A downhole assembly of an artificial lift system includes: an adapter for connection to production tubing; a receptacle shaft; an up-thrust bearing; a centrifugal pump; and a down-thrust bearing. The receptacle shaft has a latch profile for receiving a latch fastener of a drive coupling and a torsional profile for mating with the coupling to longitudinally and torsionally connect thereto. The up-thrust bearing includes: a thrust driver longitudinally and torsionally connected to the receptacle shaft; and a thrust carrier connected to the adapter. The centrifugal pump includes: a diffuser connected to the adapter; a pump shaft torsionally connected to the receptacle shaft; and an impeller connected to the pump shaft. The down-thrust bearing includes: a thrust driver longitudinally and torsionally connected to the pump shaft; and a thrust carrier connected to the adapter.

An exemplary method of controlling an artificial lift system may include monitoring, via a downhole phase change sensor, for an indication of steam breakthrough, determining the occurrence of a steam breakthrough event based on the indication of steam breakthrough, and adjusting one or more parameters of the artificial lift system based on the determination. One example system for controlling an artificial lift system may include a downhole phase change sensor configured to monitor for an indication of steam breakthrough and a processing system configured to determine the occurrence of a steam breakthrough event based on the indication of steam breakthrough and adjust one or more parameters of the artificial lift system based on the determination.

A method of pumping production fluid from a wellbore includes deploying a centrifugal pump into a production wellbore; and pumping hydrocarbons from the production wellbore by rotating an impeller of the centrifugal pump in the production wellbore from surface using a drive string, wherein the impeller is rotated at a speed less than or equal to seventeen hundred fifty revolutions per minute.
