1. An image reconstruction method from electrical capacitance tomography data comprising:

  • (a) obtaining the measurement electrical capacitance tomography data by using a recording sensor formed by an array of electrodes located on the perimeter of an oil-pipe, well or tank;

    (b) processing said measurement data using the Method of Simulated Annealing for the estimation of an electrical permittivity distribution image; and

    (c) displaying said processed image on a display device in order to visualize multiphase oil-flows through a cross section of a pipe, well or tank.
