E-472 - Well Intervention & Pressure Control - Level 2

5 days WEL/WELINE2
Level
Foundation
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.
Purpose
  • 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 tool used during well interventions and Work-overs,
  • be aware of the methods used to control well pressure,
  • learn procedures and equipment used in wireline, coiled tubing, snubbing, work-over,
  • obtain the level 2 IWCF certification on “Well Intervention”.
Prerequisite
  • Basic technical knowledge of the petroleum industry.
Ways and means
  • PPT presentation
  • Course material (PPT, PDF)
  • Exercise book
  • Certified IWCF instructor
Observation
The certification Level 2 is mandatory for the first IWCF certification. A waiting period of 10 days minimum is prescribed by IWCF before any registration to the next level. Validity of Level 2 certificate is 5 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
