Torque and Drag-Two Factors in Extended-Reach Drilling

Journal of Petroleum Technology, 1994
Summary This paper addresses the various aspects of torque and drag problems encountered in drilling extended-reach wells. It discusses how to use torque and drag calculations and measurements to plan long-reach well profiles, to execute drilling operations that minimize torque and drag effects, to monitor hole ...

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
