IWCF Well Control

The program consists of a Practical Assessment Exercise and Written Test papers on Equipment and Principles & Procedures for office engineers (Level 2), drillers (Level 3) and drilling supervisors (Level 4) based on the IWCF Certification Standards.

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 responsibly.

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 level 3 and level 4, 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 program comprises separate levels of tests for office engineers (Level 2), drillers (Level 3) and drilling supervisors (Level 4) in either Surface BOP Stack operations or Combined Surface/Subsea BOP Stack operations.

Who should attend?

Drilling Representatives, Drilling Supervisors, Toolpushers, Drillers, Assistant Driller, who desire IWCF certification as a Driller and Drilling Supervisor or for those who want a thorough knowledge of well control techniques, etc.
