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 Drilling Fluid Engineering.
This book presents how to apply fluid mechanics on drilling fluid related challenges and explains the related physics involved and the different engineering approaches. Mud has many functions, the single most important one is to remove the cuttings a) away from under the bit and b) transport them from the bottom to the surface. Viscosity of drilling fluids is not a constant parameter; it varies with shear rate. Pipe, rock bit and annular friction pressure loss has high importance for several tasks. Stable wellbore includes many sub tasks like chemical stability and filtration control.
These exercises have been developed to fit the content of the text book Drilling Fluid Engineering. The understanding of the physics and mathematics of the processes has been in focus of both the textbook and the exercises book. Many practical applications have also been created and entered into the collection of exercises. Most of the exercises have been solved and corrected by students in the corresponding course at the Department of Petroleum Engineering and Applied Geophysics at NTNU in Trondheim.
