Abstract:
A method for cement bond logging and targeted intervention, including lowering a cylindrical n×m array of ultrasound (US) transducers into a well, firing the US transducers to transmit US signals into a well casing, converting reflected US signals received by the transducers into electronic form and transmit the converted signals to a control unit, analyzing the converted signals to detect holidays, if a holiday is detected, determining a position and angle of the holiday with respect to the transducers, and applying a high intensity focused ultrasound (HIFU) signal to the well casing to fill the holiday.
