Helical Buckling of Coiled Tubing in Directional Oil Wellbores

SIMULIA's picture

Coiled tubing is used in a variety of oil well operations including drilling, completions, and  remedial activities. For each of these applications coiled tubing offers the benefits of reduced costs, speed, and reduced environmental impact. Coiled tubing possesses a limitation  however, in that it may buckle in service. In this situation the tubing may be damaged, and operations may be delayed or disrupted. In this Technology Brief, we provide a methodology for evaluating the buckling behavior of coiled wellbore tube.
