These exercises have been made to fit the content of the book Pressure Control During Oil Well Drilling , a book that was revised and updated in 2012, mostly on basis of input from my students). Also in present book all the exercises have been solved by students in the relevant course at the Department of Petroleum Engineering and Applied Geophysics at NTNU of Trondheim, Norway. It would be highly appreciated if the readers contacted me at with comments to this collection of exercises
