Oil well improvement system

Abstract

Two functionally and physically integrated subsystems form a supplemental disaster preventive system for offshore oil wells. A multi-function well subsystem modifies the sea-floor and in-well equipment to provide maintenance access, tools to cap the well, seal/re-seal the well, drill/re-drill the well, kill the well from the top, improve BOP reliability, add BOP functional redundancy, improve the cementing process, incorporate a sea-floor pressure relief/diversion function and improve the well's life cycle safety. A dome top cylindrical sidewall structure encloses the well's sea-floor equipment providing improved structural strength as well as passive protection from natural/human induced disasters. An intrusion detection and response subsystem provides sensing, processing and communication devices to detect, track & classify the 3D aspects of air/surface/sub-surface objects around a specific oil well or group of oil wells and provides the means to evaluate and eliminate threats.
