ABSTRACT The paper addresses a recently developed mathematical model for coiled tubing fatigue life prediction. It is shown that the coiled tubing stress-strain condition is unique and is primarily characterized by plane elastic stress state induced by internal pressure and superimposed over extremely high plastic ...

SPE/ICoTA Coiled Tubing Roundtable, 2000
Abstract It has long been known that CT rotates during its life because the orientation of the seam weld at the end of the CT varies. This rotation changes the bending plane and thus the fatigue life of the CT. None of the current CT fatigue and deformation (elongation and diametrical growth) prediction models considers this rotation.

New Higher-Strength Coiled Tubing Developed to Extend Coiled Tubing Operating Envelopes
SPE/ICoTA Coiled Tubing & Well Intervention Conference and Exhibition, 2011Abstract A new high strength coiled tubing grade has been developed to address the demands for improved axial strength, better fatigue performance and the ability to function at higher operating pressures. Coiled tubing service companies and operators defined several areas where existing coiled tubing grades are not considered capable of

Coiled Tubing Drilling Optimization
2001The use of coiled tubing in drilling operations in the world is today a normal situation. Through the development of any technology there is a possibility of optimization. Available coiled tubing diameters have been increased three times and materials quality almost doubled.
