E-493 - Well Intervention & Pressure Control - Level 2

5 days
WEL/WELINE2
Sessions
This course is not scheduled.
Who should attend?

Audience

    • All personnel concerned with well intervention operations (wire-line, coiled tubing, snubbing, work-over) involved in operations linked to the detection of a kick: engineers, supervisors and operators who have to supervise or carry out well intervention operations.

Level

  • Foundation
  • To raise the awareness of the negative impact and effect of a well control incident. To provide the required comprehensive knowledge and skills to carry out well intervention operations.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • understand the impact and consequences of a blowout,
  • know the safety barrier principles,
  • understand the behavior of a producing well,
  • learn the various tools used during well interventions and workovers,
  • be aware of the methods used to control well pressure,
  • learn procedures and equipment used in wireline, coiled tubing, snubbing, workover,
  • obtain the level 2 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 …).

COMPLETION EQUIPMENT

0.5 day

  • Different types of completion.
  • Downhole equipment (packers, safety valves), 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…).
