the bottom and top of each section of a
casing string and graphically displayed with
the cemented tension load. As long as the
cemented axial tension load is greater than
the stabilizing force, no buckling occurs.

The compressive force necessary to buckle casing or
tubing in a sinusoldal form in a horizontal well has
been investigated by Chen, Lin and Ahentha:
The same study shows helical buckling an occur if a
compressive force exceeds the critical force in the
It was also noted that a lockup condition, where
buckled pipe could not be for...
