Design of a Testing Facility for Investigation of Drill Pipes Fatigue Failure
The Journal of Engineering Research, 2017 Drillstring and down-hole tool failure usually results from failing to control one or more of the vibration mechanisms. The solution starts with the ability to measure different modes of vibration, hence identifying different vibration mechanisms ...

Push-and-Twist Drillstring Assemblies [PDF]
Earth and Space 2016, 2016 Deep drilling using a rigid drillstring requires the assembly and disassembly of multiple drill pipes. The interfaces between these pipes provide a challenge for automation because they must transmit large drilling forces and movements while, at the same time, minimise the actions and forces that are needed to make or break the interface.\ud A geometry

Dynamic Analysis of Stick-Slip Motion of Drillstring While Drilling
, 2011 Drilling dynamic dysfunction condition occurs when dynamic forces in the drillstring cause very high stresses and fatigue or physical damage to the string and thus reduced bit performance or caused wellbore damage.

On the formation of limit cycle of the friction-induced stick-slip vibration in oilwell drillstring
Petroleum, 2015 In this paper, the stick-slip vibration in oilwell drillstring is studied. The drilling system is modelled as a lumped-parameter torsional pendulum and the interaction between the drill bit and the rock is treated as Coulomb friction.
