Abstract
Reliability and the minimization of equipment downtime is an aspect of coiled tubing operations that is desirable, but all too often planned performance is below expectations.
The web enabled system presented in this paper allows operations engineers to review individual verification and inspection processes, monitor individual equipment compliance and decide on levels of verification activity based on historical reporting and defined operating hazards.
The starting point of the process is the development of the criticality matrix by the specifying engineer. The matrix is reviewed to determine the criticality ranking from a safety and business perspective. Once all critical elements have been defined and the level of assurance required is agreed with the client the assurance engineer prepares clear performance standards for each item of equipment and a crew competency assurance matrix.
The equipment and personnel are then inspected to the level established in the performance standards. This can involve full dynamic testing of the equipment, review of certification and maintenance records, personnel competence and work experience.
Using defined inspection criteria, the critical elements are assessed. Deviations from the criteria are actioned and a subsequent report raised and ranked according to impact.
Data generated by BP projects show a significant long term improvement trend of increased equipment reliability contributing to a major boost in client confidence in coiled tubing conveyed operations. This has been positively attributed as a result of the adoption of a reliability assurance management system.
