Course Title: IWCF / IADC – WELL INTERVENTION
Program Objectives:
-Course is Designed to enhance understanding of Well Intervention principals and
operations such as the Coiled tubing & Wire line operations and to help well intervention
specialists, well service supervisors, and petroleum engineers to become more aware of
the problems that can arise in the planning and execution of well interventions & how
their job can directly impact the productivity. Early identification of problems in wells
and effective interventions to fix problems can have a significant impact by minimizing
nonproductive time as well as discussing best practices.
-This Program meets international guidelines and IWCF/IADC certification of
written.
