Abstract: A production monitoring system comprises a plurality of production and injection wells coupled in operation to sensors for measuring physical processes occurring in operation in the production and injection wells and generating corresponding measurement signals for computing software. The computing hardware is operable to execute software products to analyze said measurement signals to abstract a parameter representation of said measurement signals, and to apply said parameters to estimate at least one parametric model of said plurality of injection and production wells, and to employ one of these models for monitoring the system.

Abstract: A production monitoring system (10) comprises a plurality of injection and production units (80) coupled in operation to sensors (410) for measuring physical processes occurring in operation in the injection and production units (80) and generating corresponding measurement signals (420) for computing hardware (400). The computing hardware (400) is operable to execute software products (300) for processing the signals (420). Moreover, the software products (300) are adapted for the computing hardware (400) to analyze the measurement signals (420) to abstract a parameter representation of the measurement signals (420), and to apply a temporal analysis of the parameters to identify temporally slow processes and temporally fast processes therein, and to employ information representative of the slow processes and fast processes to control a management process for controlling operation of the system (10).

Abstract: A petroleum stream measurement system includes a cell made of non-conductive material for passing a flowing petroleum stream. First and second sensors, spatially arranged with the cell and spaced at a predetermined distance apart, sense the capacitance of the petroleum stream and provides representative signals. A third sensor senses the capacitance of the petroleum stream and provides a corresponding signal. A fourth sensor senses the capacitance of the petroleum stream and provides a signal corresponding thereto. Apparatus receiving the signals from all the sensors derives the distribution of the different fluids within the petroleum stream.
