BOP Stack and Well Control

Objectives:

This course was designed to cover the components of BOP and related operating equipments.

  • Participants will be able to deal with the equipment thoroughly; several case studies will be presented and discussing the problems which had been faced.

  • Understanding of fluid pressure in well bore has made possible improved techniques for well-pressure control and has given drilling engineers more confidence when handling well kicks.
