Investigation of field scenarios using a 4n degrees of freedom transient torque and drag model

Ambrus, Adrian; Cayeux, Eric; Shor, Roman (Peer reviewed; Journal article, 2023)

A coupled drill string dynamics model presents an opportunity to understand, replicate and potentially control the vibrations occurring along a drill string in a deep well. This paper describes a 4n degrees of freedom ...
Stick-slip and torsional friction factors in inclined wellbores

Aarsnes, Ulf Jakob Flø; Shor, Roman (Peer reviewed; Journal article, 2018)

Stick slip is usually considered a phenomenon of bit-rock interaction, but is also often observed in the field with the bit off bottom. In this paper we present a distributed model of a drill string with an along-string ...
