... Abstract This paper presents technical features and associated benefits of a recently developed under reamer technology and its applications in the offshore Norway Oseberg South field to drill 12 ¼″ × 13 ½″ and 8 ½″ × 9 ½″ sections. It discusses the results of the operations and demonstrates...

The analytical approach developed in this paper calculates thermoporoelastic coupled time-dependent stress, pore pressure and temperature variations for an inclined borehole that is drilled through permeable or impermeable...

... of this approach, which was then transferred into the hole opening while drilling operations within a satellite field. Examples are included with novel insight into the response of under-reaming assemblies as the reamer encounters formation changes, an in-depth analysis of the static and dynamic loads placed...
