  • What's new in artificial lift


    J. F. Lea, H. W. Winkler and R. E. Snyder

    Described here are 19 recent downhole and surface equipment developments from 13 companies. Part 2, in May, will introduce developments in Electrical Submersible Pumping (ESP) and other miscellaneous new artificial lift applications. Sucker rod pumping has, in many cases, evolved from classic beam pumps to include tower-type units. It is the most widely used form of artificial lift, usually involving the application of vertical rod motions, but now also cable, to operate a downhole reciprocating pump. New technologies have focused on increasing downhole pump life and efficiencies, and on prevention of sand wear. Progressing Cavity Pump (PCP) systems are based on a surface drive rotating a rod string, which drives a downhole pump rotor operating within an elastomeric stator. Gas well deliquefying is the removal of liquid covering the producing formation to increase gas production. Gas lift uses downhole valves to inject annulus gas into the tubing under liquid columns...
