... susceptible portion of the coiled tubing string from corrosion. This paper will discuss the development process for the coating as well as initial case histories. Steel is plastically deformed in the manufacturing process to make coiled tubing, and the product is repeatedly plastically deformed in operations...

... Abstract There is a demand in the industry for coiled tubing (CT) that can safely reach significantly farther in horizontal wells than the current, steel based technology can reach. Some have suggested that CT composed of lighter materials could maintain a neutral or positive buoyancy (floating...

An analysis of the basic coiled tubing steels used indicates that for HSLA C-Mn steels, these materials have some inherent resistance to sulfide stress cracking and hydrogen embrittlement. However, both laboratory testing and field experience has shown that they are not completely immune...
