Abstract: This paper studies tubular buckling in curved wellbores (such as the build section of horizontal wells) and its effect on tubular “lockup” in horizontal or extended-reach wells. New buckling ...

Abstract: This paper studies sinusoidal and helical buckling of tubulars in inclined wellbores and the “lockup” of tubulars due to buckling. The results show that tubular buckling starts from the tubular ...
