  • Characterization of fluid inside pipe using multi frequency electrical signal
    Patent number: 11536676
    Abstract: A multi-frequency signal may be used to induce voltage difference across a portion of a pipe. The voltage difference may be induced to take multi-frequency measurement of impedance characteristics of fluid inside the pipe. The multi-frequency measurement of the impedance characteristic of the fluid inside the pipe may be used to determine a characteristic of the fluid inside the pipe. This may be achieved by active integration of experimental data with high-resolution multi-frequency electrical impedance tomography (MFEIT) modeling.
    Type: Grant

  • DOWNHOLE ELECTRODE PLACEMENT OPTIMIZATION
    Publication number: 20220180028
    Abstract: A method for determining placement of MFEIT sensors in a horizontal well for detecting producing stages of the horizontal well. Embodiments involve computationally modeling the underlying physics of a well system and performing inversion to identify the MFEIT parameters (locations and conductivity) from electrical impedance measurements.
