IWCF-Well Intervention Pressure Control Training

IWCF-Well Intervention Pressure Control Training – Course Major Topics

The course provides an understanding of pressure control methods related to well-servicing methods and equipment. The following certification options are provided:

  • Completion Operations (compulsory)
  • Completion Equipment (compulsory)
  • Coiled Tubing Operations (optional)
  • Wireline Operations (optional)
  • Snubbing Operations (optional)

Course participants must attempt both compulsory and one or more optional components in a combined certification programme. To obtain a combined certificate, participants must pass each component they have been nominated for. Furthermore, participants may choose to sit the IWCF assessment examination as either Level 3 (Operator) or Level 4 (Supervisor) in one, two or three equipment categories (wireline, snubbing and / or coil tubing). The IWCF certificate is endorsed with the achieved assessment. The course is led by instructors with extensive experience in well services and is delivered through Classroom / Online  theories, case studies, group discussion as well as practical simulator exercises.

Course Objectives

The IWCF Well Intervention Pressure Control level 3 & 4 course is designed for operators and supervisors and provides the knowledge and skills necessary to effectively and safely control a well during well intervention operations. The IWCF Certification in Norway is a government imposed certificate for leading well service personnel and must be renewed every two years. The Course is suitable for Drillers / Drilling Supervisors / Well Service Supervisors / Well Intervention Supervisors and Senior Operators and Equipment Operators.
