Well Intervention & Pressure Control - Level 3 or 4WEL/WELINE3-4

Who should attend?

  • This course aims to raise the awareness of the negative impact and effect of a well control incident. To provide an understanding of well intervention and pressure control techniques with the necessary skills to plan, supervise and carry out well intervention operations.
Audience :
  • Personnel concerned with well intervention operations (wire-line, coiled tubing, snubbing, work-over): engineers, supervisors and operators who have to plan, supervise or carry out well intervention operations.

Level : Proficiency

Course Content

  • BASIC PRINCIPLES & WELL FUNDAMENTALS

      • Type of well effluents (heavy oil, oil, gas).
      • Hydrostatic and hydrodynamic pressures.
      • Specific gravities, densities, pressure gradient.
      • Over-balance/under-balance.
      • Pore pressure, frac pressure.
  • PRESSURE CONTROL APPLIED TO COMPLETION & WELL INTERVENTION

      • Safety barriers, pressure tests.
      • Well calculation (pressure, volume, kill fluid, pumping time, balancing the pressure at the depth of the circulating device…).
      • Shut in procedures.
      • Kill methods (direct or reverse circulation, bull heading, lubricate and bleed…).
      • Specific problems linked to producing wells (losses, plugging, migration, hydrates, H2S and CO2 …).
      • Responsibilities, decision making.
  • COMPLETION EQUIPMENT

      • Different types of completion.
      • Downhole equipment as: packers, safety valves SCSSSV, nipples, side pocket mandrels, tubing (sizes, grades and connections), Xmas tree…
  • DIFFERENT TYPES OF INTERVENTION WITH THEIR RESPECTIVE EQUIPMENT

      • Wire line intervention (optional)
      • Safety barriers and specific equipment.
      • Rigging up and pressure tests surface pressure control equipment.
      • Slick line: specific equipment (BOP, lubricator, stuffing box, cable cutter valve…).
      • Braided line, e-line: specific equipment (twin BOP, grease injection system, pack-off system, tool trap, tool catcher…).
      • Problems during the interventions, interpretation and decision (shut in).
      • Coiled tubing (optional)
      • Barriers and specific equipment (strippers, BOP…).
      • Rigging up and pressure tests surface pressure control equipment.
      • Problems during the interventions, interpretation and decision (shut in).
      • Snubbing (optional)
      • Barriers and specific equipment (strippers, BOP, stripping rams, safety rams…).
      • Rigging up and pressure tests surface pressure control equipment.
      • Problems during the interventions, interpretation and decision (shut in).
