THE APPROXIMATE DEPTH DRILL STRING STUCK


Weight of string, including Block. (TSW)
Pick pipe up to this weight (TSW) and mark at rotary.
Pull required force for pipe size in use (see chart).
Mark pipe at rotary.
Measure distance between the two marks.

6. This will give you 3.5" of stretch per 1000' of free pipe.
7. Depth pipe stuck = [(stretch pulled) / 3.5) x 1000)].
