Open the CIPO recordAbstract From the Canadian patent
A method and a system to provide allocation of mixed flows back to individual sources in an oil and/or gas production system. The method is independent of sub sea on-line measurements. Instead the method uses comparably inexpensive topside equipment for compositional allocation of the flows. The method comprises the use of an on-line allocation algorithm. The method is suitable where improved reliability of flow allocation back to wells and reservoirs is needed. The allocated flow may be used to calculate and estimate the remaining volumes in a reservoir.

Why it's free to use
- Filed May 7, 2004 and granted April 24, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 7, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 7, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
