(Aarsnes and Shor, 2018) Transient Torsional Drillstring Model

Transient Torsional Drillstring Model, as published in :

Aarsnes, Ulf Jakob F., and Roman J. Shor. "Torsional vibrations with bit off bottom: Modeling, characterization and field data validation." Journal of Petroleum Science and Engineering 163 (2018): 712-721.

Documentation

The supplied model is written for Matlab (versions 2016 - 2021). To run the code, run MAIN.m.

Benchmarking

Limitations:

  • Only torsional dynamics are considered
  • The drillbit is off bottom
  • There is continuous contact between the drillstring the borehole (soft string model assumption)

Test cases:

  • Validation results are available in the referenced journal paper
