Lex Lim, petroleum engineer for PTTCO: “How does one determine that an individual is competent and
has the required skill and knowledge? After passing a well control examination, does it indicate that an
individual has acquired the required level of competency for his or her assigned jobs?”
What is the difference between IADC & IWCF?
“They are two different approaches,
IADC focuses on training,
while IWCF focuses on training and testing (examination),
but the consensus of regulators around the world is that either
provide the required basic foundation of well control training."

IWCF ROTARY DRILLING WELL CONTROL

Testing Methodology
The Certification Standards are based on a detailed analysis of the well control knowledge that Drillers
and Supervisors require, and the practical tasks that they have to master, in order to perform their jobs.
The standards have been devised so that the measurement of their skills and knowledge can be
assessed systematically. The method of assessing the performance of an individual, at both Driller and
Supervisor level, is divided into the following sections:

• A simulated practical exercise to assess practical skills
• Written test papers on Equipment and Principles & Procedures to assess knowledge based skills.

The certification programme comprises separate levels of tests for Drillers and Supervisors in either
Surface Stack operations or Combined Surface/Subsea Stack operations. Only one level of testing is
carried out at each session. To obtain a certificate, the candidate must achieve a minimum grade of 70%
in each of the three sections of the programme.

Practical Assessment
Each candidate is required to demonstrate his or her practical knowledge during a single well kill
assessment exercise conducted on either an electronic simulator or a pressurised training well. For
Combined Surface/Subsea candidates the simulation must utilise a Subsea well model and BOP panel.

Equipment Knowledge
The candidate is required to complete a written test paper that includes questions based on equipment
diagrams and schematics, API specifications and multiple-choice problems.

Principles and Procedures Knowledge
The candidate is required to complete a written test paper comprising multiple choice and direct answer
questions.


IWCF WELL INTERVENTION PRESSURE CONTROL

Testing Methodology
The Certification Standards are based on a detailed analysis of the pressure control knowledge required
by service equipment operators and supervisory personnel in order to perform their jobs. The standards
have been devised so that the measurement of their knowledge can be assessed systematically.
The method of assessing the knowledge of an individual is by written examination. The following
certification options are provided: -

• Coiled Tubing Operations.
• Wireline Operations.
• Snubbing Operations.

Candidates may combine two or more of the above options in a Combined Operations certification
programme. To obtain a combined certificate candidates must pass each of the operations test papers
that they sit.

The certification programme comprises separate levels of tests for Service Equipment Operators (Level.
1) and Well Intervention Supervisors (Level.2).

Equipment Knowledge
Candidates for each of the options must complete a compulsory paper on Completion Equipment
followed by specific Equipment paper(s) on their relevant discipline(s). The papers include questions
based on equipment diagrams, schematics, specifications, and application practices.

Principles and Procedures Knowledge
Candidates are required to complete a written test paper comprising multiple choice, well calculations,
and direct answer questions.
