E-473 - Well Intervention & Pressure Control - Level 3 or 4

5 days WEL/WELINE3-4
Level
Proficiency
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.
Purpose
  • 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”.
Prerequisite
  • The trainees, to reach this certification level, must have passed successfully the level 2 for more than 10 days, or the level 3 or 4 for less than 4 years.
Ways and means
  • PPT Presentation.
  • Course material (PPT, PDF, Word).
  • Exercise book.
  • Practice on simulator.
  • Certified IWCF instructor.
Observation
Course duration can be expanded to 2 weeks for a tailor-made program. The certification level 2 is mandatory for the first IWCF certification. A waiting period of minimum 10 days is prescribed by IWCF before any registration to the next level. Validity of Level 3 or 4 certificate is 2 years.

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
