Who should attend?

  • This course provides a comprehensive, practical knowledge of coiled tubing equipment and operations on a producing well.
Public :
  • Engineers, supervisors, technicians from operating or service companies, involved in completion, workover and stimulation.

Level :Skilled

Prerequisite :
  • Basic knowledge of well completion and well intervention.

Course Content

  • BASIC DATA - Duration : 0.25 Day

      • Importance of nitrogen in stimulation and workover.
      • Importance of coiled tubing in completion and workover.

  • NITROGEN - NITRIFIED ACID - FOAMED ACID - Duration : 1 Day

      • Nitrogen (properties, basic formula for design).
      • Specifications for nitrogen storage and pumping equipment.
      • Two-phase fluids and foams (properties, chart and tables for design, difference between foam and two phase fluids), diverting effect of foamed fluid.
      • Stimulation methodology, flow back procedure.

  • COILED TUBING EQUIPMENT (technology, dimension, weight) - Duration : 0.75 Day

      • Main components: reel, injector, BOP and related equipment.
      • Auxiliary equipment: crane, pumping equipment, etc.
      • Downhole tools: connectors, safety equipment, circulating tools, downhole motor, fishing tools, inflatable packers, etc.
      • Guide for safe equipment rig-up.

  • PIPE CHARACTERISTICS & BEHAVIOR - Duration : 0.5 Day

      • Geometric and mechanical properties: geometry, metallurgy, performance, characteristic curve.
      • Tubing behavior (at surface, in hole): fatigue, buckling, tension and pressure limits (tubing force analysis, model for operation design).
      • Measuring and recording of operating parameters.

  • COILED TUBING APPLICATIONS - Duration : 2 Days

      • Kick off with nitrogen, underbalance perforating.
      • Well clean out (fill removal, wax and hydrate removal).
      • Sand control.
      • Matrix treatment: acid, solvent.
      • Other applications: CT assisted DST, conveyed tool operations in high deviated well, use as producing, gas lift or chemical injection string, fishing, underreaming, drilling.
      • Statistics, economy, areas for future development.

  • CEMENTING OPERATIONS WITH NITROGEN OR COILED TUBING - Duration : 0.5 Day

      • Foamed cement: definition, use (primary cementing, squeeze).
      • Cementing through coiled tubing: cement plug, squeeze (squeeze slurry characteristics, job design, key-points).

Learning Objectives
