Real-time Flow Assurance System
Advanced Transient Multiphase Flow System
Utilize available sensors in subsea and topside systems to gain a full picture of production along with predictive calculations. Access to the data and a current dynamic model assist in decision support, avoiding potential problems and contributing to your operation’s optimal production and performance. In addition to the real-time model these systems provide a look-ahead mode, where it is possible to predict what will happen in the future with the present operation, and a planning mode, where the operators can plan future operations.

Virtual Flow Metering System
Virtual flow metering system will improve the accuracy and reliability of the overall hydrocarbon accounting system. It is a complete dynamic virtual flow metering system where the oil and gas produced from each well will match the total production measured by a fiscal metering system located downstream. The uniqueness is to perform online heat and mass balance calculation including component tracking both under steady-state and during transient periods for the plant. It is a supplement to advanced multiphase instruments and can also be an alternative.
This system is a model based virtual flow metering system performing data validation and reconciliation of all relevant sensors in the plant. The main components in the system include a high fidelity dynamic multiphase flow and process simulation model. This model is based on first principle modelling approach including a complete heat and material balance of the fluid. The model is synchronized in real time using control signals from the field, e.g. when a valve is opened in the field, the same valve will open in the model.
Feature
Back allocates flow deviation from fiscal metering topsides
Calibration and monitoring of all field measurements
4 available simulation modes; real time, planning, predictive and retrospective mode
Detection of gas and water breakthrough in the wells
Benefits
Alternative to physical subsea meters which are typically very expensive and unreliable
Back allocate flow deviations from topsides fiscal metering
Installation and maintenance of such systems is much simpler than physical meters
