  • On-line compositional allocation
    Patent number: 6944563
    Abstract: A method and a system to provide allocation of mixed flow to individual sources in oil and gas production systems by measuring mixed flow; analyzing the composition; accessing the data for the mixed flows; and calculating the flow from each source with an allocation algorithm using the mixed flow, the analyzed composition and the composition of at least one source.

  • On-line compositional allocation
    Publication number: 20040225464
    Abstract: 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.

  • Method for detecting and correcting sensor failure in oil and gas production system
    Patent number: 6772082
    Abstract: Sensor failure in an oil and gas production system is monitored and detected by checking the consistency of the measurements of the sensor in question using a computer-based process model with the measurements of the other sensors in the system. The present invention also generates a back-up value for a failing sensor with the process model by identifying the value that is most consistent with the measurements of the other sensors in the system.
