Being able to calculate the estimated production and injection rates of oil, gas and water at all key locations in an oil and gas production facility can make the difference between failure and success in complex oil and gas operations.

Kongsberg Oil & Gas Technologies’ Overall Flow Metering Systems (OFMS) or production reconciliation systems are aimed at integrating all available sensors in both the subsea and topside systems. These can then provide a full and detailed dynamic model of the complete process.

The reconciliation system is a powerful tool for allocating production to wells, detecting sensor failure and calculating high-quality estimates of production and environmental performance.

The system is used for reconciliation of all measurement data in field operations - from bottom-hole to the metering skid downstream of the topside process. We have developed a unique technique based on its high-fidelity, dynamic process simulators and using our expertise in real-time model based support tools for dynamic as well as steady state. Many of these projects incorporate complex multi-phase tie-backs, and hence variations in hold-up and other transient phenomena are key issues to consider when reconciling measurements over.
