Investigation of drillstring vibration reduction tools [PDF]
Drilling related problems such as drillstring vibration is an important cause of premature failure of drillstring components and drilling inefficiency. The vibration of drillstring interferes with measurement collected while drilling.

Study of Stick-slip torsional vibration in Drilling Operation [PDF]
The purpose of this work is to analyze drill string torsional vibrations modes, and to advise on whether it is best to minimize, if not entirely eliminate these vibration or if they can be utilize to the benefit of the drilling performances.

Practical approach to modelling and controlling stick-slip oscillations in oilwell drillstrings [PDF]
Stick-slip friction-induced oscillations appearing in oilwell drillstrings are a source of failures which reduce penetration rates and increase drilling operation costs.

LATERAL VIBRATION ANALYSIS OF DRILLSTRING USING FINITE ELEMENT METHOD [PDF]
This project investigates lateral vibration of a drillstring under the action of weight on bit and drillstring rotation. The dominant cause of drillstring and bottom hole assembly’s failures, shocks and severe damages to borehole wall is recognized to be

Suppressing Axial-Torsional Coupled Vibrations in Drillstrings
In drilling operation, a wide variety of oscillations causing failures often arise. Torsional vibrations (stick-slip) are originated by the cutting device (bit) motion, these vibrations in turn excite axial oscillations causing a phenomenon known as bit-bouncing.
