Coiled tubing

The authors describe the applicability of 110,000-psi yield-strength quench-and-tempered coiled tubing strings in high-pressure sour environments through implementation of a custom-fit coiled tubing integrity and risk-mitigation program.
This paper describes a new concept for a reel mover used for coiled tubing deployment and operation.
In this year’s feature are two case histories and an equipment-development paper, all of which are, by accident rather than design, from operations undertaken in the Gulf States. Each, in its own way, exemplifies the engineering decisions and balances that must be weighed to provide the best solution within limiting parameters and the considerable effort this may take…
