Torque and Drag modeling is essential for pre-job design when determining if the intervening tubing (coiled tubing, drill string, or wireline) can reach the target depth of a well successfully. In addition to this, it is utilized in post-job analysis or real-time monitoring/modeling to calibrate against measured job parameters e.g. surface weight.
This half-day course provides an overview of well intervention theory along with various modes of intervention that include coiled tubing, drill string, and wireline. Tubing force analysis consists of concepts such understanding buckling behavior, prediction of lock-up depth, estimation of maximum set-down weight/overpull and pipe length changes (stretch) during well intervention.
Various techniques to achieve extended reach (e.g. lubricants, downhole vibrators, tractors) are also covered. Effects of pipe rotation is considered for torque analysis during drill string intervention and wireline operation is discussed along with pump down analysis. Field examples are considered for all modes of intervention and the concepts learned will be demonstrated with a commercially available software product. In addition, participants will be provided with a temporary license to use the software during the course for a hands-on experience in torque and drag modeling.
This course will provide 4 hours of continuing education credits accredited by SPE Gulf Coast.
