Managed Pressure Drilling

With extraction out of depleted wells more important than ever, this new and developing technologyis literally changing drilling engineering for future generations. Never before published in book form, these cutting-edge technologies and the processes that surround them are explained in easy-tounderstandlanguage, complete with worked examples, problems and solutions. This volume is invaluableas a textbook for both the engineering student and the veteran engineer who needs to keep up withchanging technology.
