Rethinking Coiled Tubing String Lifespan Assessment: Leveraging Frequent Inspections for Enhanced Operational Insights
Bibliographic record
Abstract
Abstract Traditionally, the industry benchmark for determining the lifespan of a coiled tubing string has relied on conventional parameters like running meters or fatigue analysis. This study will highlight the benefits of utilizing frequent coiled tubing string inspections as a key factor in assessing the effective remaining operational life of coiled tubing strings. The study aims to provide valuable insights that can enhance decision-making in asset management and maintenance procedures. A sample of coiled tubing strings across various operational environments underwent inspections at key intervals during their respective operational lifespans. Rigorous inspection protocols were implemented, capturing data on factors like corrosion, material degradation, and stress-induced deformities. A comparative analysis was conducted using historical data obtained from running meters and fatigue analysis to highlight the unique insights provided by frequent inspections. The findings of this study underscore the significance of frequent string inspections in assessing the operational lifespan of coiled tubing strings. While traditional methods such as running meters and fatigue analysis remain informative, they often overlook localized stressors and gradual deterioration that can compromise string integrity. In contrast, frequent inspections offer insights into the evolving condition of the strings, enabling timely interventions to prevent catastrophic failures. Furthermore, the data collected from frequent inspections can be utilized in an effective manner to anticipate future wear patterns and potential failure points. This proactive approach to maintenance and asset management enhances operational efficiency, reduces downtime, and optimizes resource allocation. This study sheds light on a significant departure from the traditional industry practice of assessing the lifespan of a coiled tubing string through conventional means. Shifting the service industry's focus toward frequent inspections as a new perspective for assessing coiled tubing string lifespan holds positive implications for asset management and maintenance strategies. By embracing this approach, service companies can make more informed decisions about when to replace or repair coiled tubing strings, ultimately prolonging their service life and minimizing operational disruptions.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
