Artificial Lift & Well Intervention FundamentalsCOMP/TAWOE

Who should attend?

  • This course provides a comprehensive knowledge of artificial lift, workover implementation and killing procedures for a producing well.
Audience :
  • Participants attending the training program “Drilling & Completion Engineering” (page 154).

Level : Foundation

Course Content

  • ARTIFICIAL LIFT BY CONTINUOUS GAS LIFT

      • Continuous gas lift: principle, well unloading, operating procedure and troubleshooting, field of application.
  • ARTIFICIAL LIFT BY PUMPING

      • Sucker rod pumping, Electrical Submersible centrifugal Pumping (ESP): principle, specific completion equipment, operating procedure and troubleshooting, field of application.
  • TYPES & MEANS OF INTERVENTION ON PRODUCING WELLS

      • Mains types of intervention: measurement, maintenance, workover.
      • Main means (wireline unit, coiled tubing unit, snubbing unit, workover rig): principles, area of application.
  • GENERAL PROCEDURE OF A WORKOVER

      • Main operation steps: chronology, more tricky operations from a safety point of view, main operations.
      • Case of depleted reservoirs: losses and formation damage, kick-off after the workover.
  • WELL KILLING PROCEDURE FOR A PRODUCING WELL

      • Killing the well by circulation: area of application, basis procedures (direct or reverse circulation), elaboration of the forward-looking pumping diagram.
      • Killing by squeeze: area of application, basis procedure, elaboration of the operating program, case where the injectivity test is unsatisfactory, squeeze and bleed-off method.
      • Final killing phase: observing the well, operations to run after packer “unsetting”.
  • CASE STUDY: WORKOVER PROGRAM

  • KNOWLEDGE ASSESSMENT

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • select the adequate artificial lift method with regard to some specific operational problems,
  • select the adequate well intervention method with regard to some specific operational problems,
  • define a well killing program (pumping diagram).

Ways & Means

  • Exercises on key parameters of artificial lift.
  • Design of a pumping diagram for killing a well.
  • Case study for a workover program with an interactive game.
  • Application to a real case (project) for the participants in the “Drilling & Completion Engineering” training course (page 154).
