Non-linear rotor dynamics as applied to oilwell drillstring vibrations
Journal of Sound and Vibration, 1991Abstract The lower part of a drillstring used for the drilling of oil or gas wells is usually composed of drill collaes (thick-walled tubulars) and stabilizers (coarsely grooved cylindrical elements of a larger diameter than the drill collars, that loosely fit in the borehole).

A simulation framework for evaluating intelligent control of continuum drillstring dynamics.
59th U.S. Rock Mechanics/Geomechanics SymposiumABSTRACT: Intelligent drilling control systems depend on accurate models of drilling dynamics to avoid destructive behaviors and boost operational efficiency. While lower-fidelity models offer rapid run-times and straightforward analysis, they suffer from some drawbacks.
