In today’s low oil price climate, more and more operators decide to work on existing producing wells rather than drill expensive new wells. At this course, participants will come away with an understanding of the significant decision areas in well workovers and interventions. Particular emphasis is given to well diagnosis, water control, acidizing, squeeze cementing, wireline techniques, concentric tubing, perforating, well control, and completion fluids.

The course is designed for:

  • Completion engineers
  • Production engineers
  • Reservoir engineers
  • Drilling engineers
  • Field supervisors
  • Production foremen
  • Engineering technicians

Learning objectives

  • Identify and Select Problem Wells
  • Prepare proposals for workovers/interventions
  • Prepare work AFE and Budget
  • Select proper kill fluids
  • Know about unloading techniques with examples
  • Use logging tools to identify well problems
  • Understand the use and functions of coiled tubing, snubbing unit, and wireline
  • Prepare programs and well diagrams
  • Evaluate and compare mechanical or chemical interventions
  • Decide and prepare for Plug and Abandonment
