ABSTRACT:
In one oil production operation, a fluid conduit transports a fluid from a wellhead to a floating production platform. To prevent an occurrence of formations that obstruct the flow of fluid in the fluid conduit, a forecast is made as to whether a flow assurance curve will intersect an operating curve of the fluid conduit. In the event that the operating curve and the flow assurance curve will intersect, the appropriate personnel may be alerted so that they may attempt to prevent the hydrate forming conditions from occurring in the pipe. Which personnel are alerted may be based on a level of criticality. The level of criticality may be based on an estimated time period remaining until the flow assurance curve and the operating curve will intersect.
