This book removes the mystery and pressure from calculations by equipping readers with the tools they need to understand calculations and how they work. This is done by using straight-forward language and showing fully worked out, rig-based examples throughout. The book comprises of mini lessons which are never more than two pages long and a complete lesson is always in view when the book is open in front of you. Lessons progress in a logical manner and once the book is finished, the reader is ready for any calculations that could be encountered at well control school.

It is a great tool for rig crew members who are afraid of calculations or have not done any math since school.  I found it easy to follow with clear explanations and it flowed from topic to topic.  A definite addition to the rig crews training toolbox.

  Dave Cormack

Dave Cormack has worked in the drilling industry out of Aberdeen, Scotland since 1983.  He has worked on over thirty drilling rigs, platforms or MODU’s either as a member of the drill crew or in a training capacity.  Since 1991 he has been exclusively involved in training drilling personnel either on the rig, in the classroom or in a management capacity worldwide.  He served a three-year term on the Board of Directors of the International Well Control Forum and was one of the contributing authors to the Well Control chapter in the recently revised International Association of Drilling Contractors definitive Drilling Manual.  He has been involved in well control training on every continent on earth bar the polar ones, has published two SPE papers and made presentations on training at global drilling conferences.  Dave still teaches well control regularly to both international certification standards and also runs courses globally, training the next wave of well control assessors for IWCF. He is passionate about helping students through their two yearly well control school and firmly believes that a solid grasp of calculation skills frees them up to  concentrate on learning well control.
