Drag Torque in Disk Brakes: Significance, Measurement and Challenges

SAE International Journal of Commercial Vehicles, 2015
<div class="section abstract"><div class="htmlview paragraph">Drag torque is generated in disk brakes as a result of contact (dynamic friction) between brake disk and brake pads when the braking system is not actuated. Among the negative implications of drag torque are, notably, dispensable additional fuel consumption as well as increased ...

Long-Step Steady State Torque and Drag Calculations

IADC/SPE International Drilling Conference and Exhibition
Abstract Recently, several initiatives have been launched to use generative methods for creating an ensemble of planned trajectories when evaluating alternatives for a drilling program. These automatically generated trajectories must be ranked according to their hydromechanical characteristics. Given that hundreds of trajectories need

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 them
