Pål has worked as a professor with students for more than 40 years. His favorite activity has been to be their guide, supervisor and co-author.
He is especially eager to develop new, useful knowledge, and to make it known for a broader audience. For this purpose, he has wr
This is the exercise book accompanying Pressure Control During Drilling
Porous sedimentary formations penetrated by the rock bit contain fluids such as oil, gas or salt water. If the hydrostatic pressure of the drilling fluid drops below the formation pore pressure, pore fluid will enter the well and “kick” the mud out of the well. To control the pressure while drilling you need to understand the behavior of gas. This book aims at explaining the physics and the engineering approaches behind pressures in the sediments, detection of unstable wellbores, equipments necessary to close and kill the well, killing methods and offshore challenges.
These exercises have been made to fit the content of the book Pressure Control During Oil Well Drilling. In present exercise book all the exercises have been solved by students in the corresponding course at the Department of Petroleum Engineering and Applied Geophysics at NTNU of Trondheim, Norway, and revised in 2015.
