Drilling Well Control

Programme Objectives

This programme is designed for people in critical well control positions on drilling installations as well as onshore roles.  The candidates will complete an IWCF accredited training course, taught according to IWCF syllabus, in order to prepare them for assessment.

Different levels of training require different examinations and are valid for varying lengths:

  • Level 2 training – Consists of two written assessments. If passed, the certificate is valid for 5 years.
  • Level 3 and 4 training – Consists of two written assessments and a practical assessment using simulator equipment. If passed, the certificate is valid for 2 years.
 

Programme Structure

  • Level 2 – Drilling and Wells Personnel Basic Training (equivalent to old Introductory level)
  • Level 3 – Available for any role expected to shut in a well (equivalent to old Driller level)
  • Level 4 – Well Site Supervisor Training (equivalent to old Supervisor level)

Candidates can opt to undertake either Surface BOP operations or Combined Surface and Subsea operations.

 

Examinations

Only one type of assessment is allowed for each candidate at a certification session. To pass the assessment and obtain a certificate, candidates must achieve a minimum mark of 70% in each section of the examination.

Each candidate is required to complete two written test papers which include multiple choice questions and Kill Sheet calculations. All candidates are allowed between 1.5 and 2.5 hours to complete this section, depending on the options taken.

The examinations are made up of multiple choice problem questions. Candidates must be able to identify equipment components and operating procedures using diagrams and schematics. All candidates are allowed one hour to complete this section.

Independent Invigilators who are registered and approved by the IWCF conduct the written tests at centres which have been approved and accredited for the purpose of the certification programme.

Timings for each exam is as follows:

  • Level 2:
    • Surface Equipment: 1 hr
    • Surface Principles and Procedures: 1.5 hrs
    • Combined Surface and Subsea Equipment: 1 hr
    • Combined Surface and Subsea Principles and Procedures: 1.5 hrs
  • Level 3:
    • Surface Equipment: 1 hr
    • Surface Principles and Procedures: 1.5 hrs
    • Combined Surface and Subsea Equipment: 1 hr
    • Combined Surface and Subsea Principles and Procedures: 2 hrs
  • Level 4:
    • Surface Equipment: 1 hr
    • Surface Principles and Procedures: 2.5 hrs
    • Combined Surface and Subsea Equipment: 1 hr
    • Combined Surface and Subsea Principles and Procedures: 2.5 hrs

Practical Assessment

Candidates undertaking a Level 3 or 4 course will also undergo a practical assessment. Assessment is usually conducted in pairs of a driller level candidate and a supervisor level candidate.

Candidates must:

  • Set up for drilling
  • Recognise a drilling break and positive kick
  • Perform the shut-in within the shortest possible time in accordance with the appropriate procedure
  • Complete the kill sheet and kill the well using the designated procedure (Wait & Weight or Driller’s Method)
  • Bring the pump up to kill speed maintaining constant bottom hole pressure
  • Operate the remote choke and make adjustments in accordance with the time delay to maintain constant bottom hole pressure
  • Complete the well kill operation
