Marine well with shallow-water flow monitoring

摘要

A marine well with shallow-water flow monitoring is for monitoring an open hole section of the marine well during marine drilling operations. The shallow water flow monitoring system 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, and wherein 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, 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.
