Abstract

The present invention addresses to a real-time flow assurance occurrence monitoring system with the aim of reducing oil production losses caused by occurrences in the flow assurance area, which uses a web tool to integrate results of simulations of multiphase flow and thermodynamic simulators with production data and specific correlations, developed to monitor the formation of deposits or blockages in subsea lines. This tool has the specific objective of monitoring the formation of hydrates, paraffins and emulsions in real time and other occurrences that may cause a production shutdown. Based on this information, it issues an alert of the occurrence in the control rooms of the operational units, supporting decision-making on operational procedures that must be carried out to avoid the loss of oil production. It further records the operations carried out to mitigate occurrences. All data is structured in tables and graphs and can be exported to other systems.
