IWCF Course

This course is meant for ‘Drilling Crew’ engaged in Exploration and Development of Hydrocarbons.

IWCF Certification is treated as mandatory for all Drilling personnel (Drillers & Supervisors) to attend this course and obtain certification every two years.

This course will be conducted by IWCF approved assessors utilizing IWCF compliant simulators.

Course Overview

Duration :   5 Days

Objectives

A single mistake on the part of a drilling crew may result in complications in a well or even lead to a blowout, which may involve loss of equipment, resources worth millions of dollars and / or loss of human life.  Therefore, it is critical to expose  all drilling crew to the skills needed for effective well control practices.
The entire course of ‘International Well Control Forum’ is based on the prescribed syllabus of IWCF, UK –

Theory covering Equipment, Principles & Procedures. 
Practicals on Simulator under direct supervision of Assessors.
