... Abstract This paper describes methods for calculating the one-dimensional, vertical variation in composition with depth caused by gravity and thermal gradients. The Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) cubic equations of state (EOS) are used as thermodynamic models. Examples...

... Abstract Drillstring stress analysis techniques are reviewed with emphasis on the use of torque-drag formulations. Some of the many modifications to torque-drag calculations are reviewed and discussed. The limitations of current results in drillstring dynamics for use in stress analysis...
