Effect of Steerable BHA on Drag and Torque In Wells
European Petroleum Conference, 1990Abstract Steerable bottom hole assemblies are often used when drilling deviated wells. Planning of such deviated wells often include studies of torque and drag calculations for the planned well-path and BHA's in order to have a fairly good idea of friction and torque to be encountered when drilling.

Modeling and Parametric Study on Drag Torque of Wet Clutch
2012In order to analyze the power torque characteristics of wet clutch produced under the disengaging state and reduce the drag torque of wet clutch, a flow rate equation under full film state was deduced based on the Navier-Stokes equations and a new equation calculated oil film equivalent radius was derived according to the relationship of oil flow rate ...

Scientific machine learning in torque and drag drillstring calculations
Extended reach (ER) drilling is a method of directional drilling defined by creating wellbores that stretch horizontally across the surface of the earth for long distances. This has proven to be a particularly useful method in the oil and gas industry, as the extra distance can allow operators to maximize productivity of a well, and also can allow themopenaire +1 more source
Calculation of drag and torque coefficients by time-independent lattice-Boltzmann method
Physical Review E, 2014A method is developed to calculate the drag and torque coefficients of an isolated particle in a Stokes flow. The method is based on solving the time-independent lattice-Boltzmann equation. The advantage of this method is that the algorithm is easy to code, the method can be applied to any shape of the particle without complicated implementation, and ...
