Torque and Drag 
Torque and Drag Software for Well Intervention Operations
Torque and Drag modeling is useful to estimate the friction forces on the intervening tubing when planning a well intervention or performing a post-job analysis. In TubeFlow PIC, torque and drag analysis can be performed by configuring coiled tubing, drill string, well tubular, or wireline as the intervening tubing.

In general, TubeFlow PIC provides the following functionality in the torque and drag model:

In addition, the torque and drag analysis is supported by utilities to accurately estimate fluid properties and burst/collapse limits during well intervention operations.
