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
  • 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.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • comply with the well integrity requirements,
  • know the safety barrier principles,
  • understand the behavior of a producing well,
  • learn the equipment of a completion,
  • apply the methods used to control well pressure,
  • learn procedures and equipment used in wireline, coiled tubing, snubbing, work-over,
  • obtain the level 3 or 4 IWCF certification on “Well Intervention”.
Course Content

BASIC PRINCIPLES & WELL FUNDAMENTALS

0.5 day

  • 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

1.5 days

  • 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

0.5 day

  • 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

2 days

  • 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).
