| This subsystem is an element of an oil well improvement (disasters preventive) system for offshore wells. This subsystem modifies existing in-well; data transmission equipment, data formatting & processing, and further modifies the processing of the existing sensors and remote controlled devices to provide enhanced capacity, reaction time & reliability for dynamically monitoring & controlling in-well resources. This sensor data and controlled tool status is further integrated into a single data base along with all seabed & platform devices and all related information (formation survey, drill plan, etc). The subsystem processes this data and develops instant status of operational conditions and provides recommendations/alerts/automated controls. Although the primary objective of the subsystem focuses on reducing/eliminating the disastrous effects of blowout, the subsystem also provides the means to alter/improve the normal/uneventful well drilling processes. | ||||||
