Torque & Drag
Several factors affect hole drag, including hole inclination, dogleg severity,
hole condition, mud properties, hole size, and drillstring component types,
sizes and placement. However, as mentioned earlier, in drilling situations
where the drillstring is not rotated (as when a steerable system is used in
the oriented mode) axial drag can become very significant and should be
evaluated using a Torque and Drag computer program. Torque and Drag
programs can be found in EC*Track and DrillByte.
