Open the CIPO recordAbstract From the Canadian patent
The invention concerns a method for calculating the relative volumetric flowrates of at least one of the phases of a multiphase effluent flowing in a well, said method comprising a first step of acquiring local volumetric fractions and/or velocities of said phases across a section of the well at a certain depth. The method further comprises: - corrections of said local volumetric fraction and/or velocity measurements in order to make them consistent with each other and/or with the effluent flow conditions; - selection of a suitable flow model mathematically representing the effluent flow; - interpolation of said local volumetric fraction measurements and/or said local velocity …

Why it's free to use
- Filed September 2, 2003 and granted January 10, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 2, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 2, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
