Where primary well control is all about the use of drilling mud to control the influx of formation fluids into the well bore, in this module we look at the components that make up secondary well control systems and the roles they play in the event that the primary well control has failed - resulting in a kick. Equipment covered includes Ram type BOPs, Annular BOPs, Choke and Kill Valves, Spools, the Bell Nipple, Control Units and Choke systems and we’ll see how they work as a system to bring the well back under control. We then move on to document some tertiary well control methods and worst case scenarios before giving an overview of the relevant API Recommended Practices for controlling well operations.
