The weak point of a string won’t necessarily occur at surface and won’t necessarily occur in the smaller/weaker pipe either (if running a taper string). In the example shown the weak point does not occur at surface, nor does it occur in the “weaker” 4½” drill pipe. The weak point actually occurs at around 600’
Did You Know? When you have a stuck pipe incident on a long horizontal well, we are told to work the pipe in the opposite direction to which it was moving when it became stuck. However, if you don’t pick up the pipe enough distance to overcome the drill string stretch, then you might not

Your Maximum Overpull can be well below the tension limit of your drill pipe? That shallow doglegs can greatly reduce your maximum overpull?What is happening: What your drill pipe feels during an overpull even is not just tension – but is a combined load of tension, torque (if present), and bending. Shallow doglegs can cause
Breakover (static) torque after connections can be a reliable indicator that the drill string is getting differential stuck. While drilling, connection practices should be tailored to capture the relevant data: Rotate FIRST after a connection (no up-down movement of the string) Record peak torque (i.e. breakover) values Compare to the dynamic off bottom torque In
