  • Patent number: 10788407
    Abstract: A system for sensing an estimated composition of a produced fluid being conducted from a reservoir includes: at least one device for measuring temperature data; at least one device for obtaining flow rate data, pressure data, pump speed data and valve travel data; a first produced fluid density generator; a second produced fluid density generator; and a composition generator. The first produced fluid density generator is configured to generate a first produced fluid density based on the obtained flow rate, pressure, pump speed and valve travel data. The second produced fluid density generator is configured to generate a second produced fluid density based at least in part on the measured temperature data. The composition generator is configured to: iteratively generate a phantom component content, a bitumen content and a water content for the produced fluid based on at least in part on: a material balance of the produced fluid.

  • Publication number: 20070061155
    Abstract: The invention provides a method for integrating the mobile vehicle with existing or future Public Land Mobile Networks (PLMN). The PLMN may be any existing cellular networks (GSM, CDMA, HSPDA, HSUPA) or future 4G network and future high speed data network WiMAX. Based on the wireless connection with existing public networks, mobile vehicle provides in-vehicle wireless connection. With unique Vehicle Identification Number (VIN) as the system ID number, the vehicle (including the in-vehicle microcomputer), the public network PLMN, and the management Distributed Database System form a so called Universal Vehicle Communication & Management System (UVCMS).
