![]() A hydraulic model was developed, combined with field data pertaining to a developed field on the Norwegian Continental Shelf, and used to model the pressure losses along a designed wellbore for four different cases: Consecutive layers with different pressure regimes This thesis sets out to evaluate the benefits and limitations of combining these two methods into a method dubbed Managed Pressure Casing Drilling, and if it enables drilling wells that were previously thought undrillable.Formations with very narrow mud windows.Examples of candidates thought to benefit from using this combination include: It is thought that a combination of the two might yield additional benefits. It has been proven through numerous field applications that both of these technologies bring value to drilling operations when used in the appropriate situations. Any use you choose to make of these tools & materials is undertaken by you entirely at you own risk.The last decade has seen the advent of new unconventional drilling methods, such as Managed Pressure Drilling and Casing/Liner Drilling. Ensure you understand the impact of using these tools. Please verify the tools provided by this application by yourself before you use them.
