A system for monitoring an open hoie section of a marine well for shallow-water flow during marine drilling operations. The system for monitoring uses time periods and intervals while mud pumps are turned off. The system uses a video feed, and a processor with data storage containing a discharge category model. The data storage receives a drilling parameter data feed, a seismic profile data feed, a logging while drilling data feed, and a measurement while drilling data feed, which are used to verify a determined discharge category as a baseline discharge category. The system provides an alarm when a discharge emergency is ascertained due to a change in discharge category without an anticipated change, or changes outside acceptable limits. |
