IWCF Well Intervention Pressure Control L2

esting understanding

  • IWCF expects candidates’ knowledge· IWCF expects candidates’ knowledge and understanding of basic well intervention pressure control to be developed so that they can“competently perform their assigned well control duties” (OGP Report 476).It is insufficient for candidates on any level of course to be simply coached to pass an exam.
  • “The quality of teaching will evolve to ensure learning objectives are met.Training will be taught in line with the stipulated syllabus and it will not be sufficient to base training on “test similar”or “test-identical” exam questions to help personnel pass the written exam”. (OGP Report 476).
Structure of the written test syllabus Learning objectives (formerly “standards”)·
  • The learning objectives in the syllabus are based on the content (subjectmatter) the instructor will teach to meet the requirements of this level.The use of the wording “learningobjective” is in line with the OGPReport 476. It is a broad overview statement of what the participant will be taught during the course.

During this course the participant will gain an understanding of:

  • Explain why pre-job site planning and the Stop Work Authority are so important.
  • Give examples of the benefits of holding meetings before any well operation.
  • Explain why well integrity or pressure isolation is confirmed before rigging up equipment on the well.
  • Define the term “hydrostatic pressure”.
  • List the factors that affect hydrostatic pressure.
  • Define the term “formation pressure”.
  • Define the term “fracture pressure”and give examples of its impact on well integrity such as formation breakdown.
  • Explain primary well control.
  • Explain secondary well control.
  • Give examples of the uses of the BOP and pressure control equipment.
  • Describe best practice of having two barriers between the source of pressure in the well and atmosphere before breaking containment.
  • Describe the principles of risk management – identify impact and probability, mitigate and control.
  • Explain the importance of recognising and managing change;explain why an MOC process is needed.
  • Describe the main items required for a kill system such as equipment and fluids.
  • Describe an in flow test.
  • Describe the roles and responsibilities in a shut-in procedure.
  • Describe the basic principle of killing a well using each of the three methods:- bull heading - reverse circulating -lubricate and bleed.
  • Identify different types of pressure gauge problems from given examples,for example, physical damage,vibration damage and loss of fluids within the gauge, and explain the correct action to take.
  • Identify different types of flanges from given examples and describe flange compatibility.
  • Describe the primary function of the Christmas Tree and well heads with particular emphasis on: - what they are - what they do - how they work/form barriers.
  • Explain the importance of drift runs
