Understanding Well Control

Understanding Well Control is not easy – we have seen the consequences of this for decades now, not least with the relatively recent Montara, Macondo, Hercules & KS Endeavour blowouts to name but a few.  This course focuses upon people understanding well control, rather than upon them just passing an exam.

Worked Examples and Case Histories are studied and discussed, at the delegates pace, so that delegates become fully involved in the understanding process.

This course particularly helps those people who are nervous about taking their WellCap / IWCF exam, who are new to Well Control or who perhaps struggle a little with well control concepts or the sciences, English or well killing in general. Excellent explanatory videos, digital film, Manuals, PowerPoints & Teamwork Exercises are used throughout.
