Course Description

This course will cover an overview of torque and drag theory, and software application, which includes the various input requirements, and the analysis and interpretation of Torque and Drag results in drilling operations. Participants will be able to use typical field cases for different drilling operational scenarios such as drilling with rotation, drilling while sliding, pickup without and with rotation, slack-off without and with rotation and rotating off bottom for drill-string design and optimization. This involves the proper selection of drill-pipe grades, class, dimensions and connections; and the number and placement of HWDP, etc. to predict and minimize torque and drag to prevent hole problems; and also meet drill-pipe design limits for tension, torque, buckling and stress within operational and rig requirements. In addition, Participants will introduce on how to compare calculated hook-load and torque values to actual field values in other to identify possible hole problems and frictional factor calibration. Participants will be able to simulate torque and drag outputs under various operational parameters, wellbore profiles and frictional factors for comparison.
