The complete paper focuses on SBOP technological advancement since the Macondo incident in 2010, with emphasis on reliability, equipment-condition monitoring, and statistical root-cause analysis. The development of new technologies has targeted overall cost optimization of the well life cycle but also has been aimed at assuring SBOP functionality. 5 Journal of Petroleum Technology ARTICULO 194656 194656 0 0 0 0 262375 BAAB BAAB 2026-03-06 200067037 0 200067037 2026-03-06 00:39:34 2026-03-06 ARTICULO
