Improvement of Torque-and-Drag Modeling in Long-Reach Wells
Modern Applied Science, 2011 Torque and drag modeling is regarded as an invaluable process to assist in well planning and to predict and prevent drilling problems. 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 and to monitor hole cleaning.
