This paper reviews a coiled tubing management system that has been in operation for over two years in European and West African operations. Complete tubing records for up to at any one time 20 coiled tubing units and in excess of 100 strings of coiled tubing have been recorded by the system. Data has been taken from the system, covering the total amount of tubing run over the period and has been broken down to show running footage between different pipe sizes, amount of failures and maintenance carried out on coiled tubing.

Corroboration of the fatigue predictions of the system is also discussed, with test results of tubing that had reached its safe working life under the CYCLE system being tested to destruction on a fatigue rig to evaluate the suitability of the fatigue algorithm used.
