THE WORKFLOW FOR THE ULTRASONIC ENHANCED SIGNAL PROCESSING TECHNIQUES IN CASED WELLS (UESTC) FOR ULTRASONIC PULSE-ECHO AND PITCH-CATCH MEASUREMENTS (IMAGE)
Caption
The workflow for the ultrasonic enhanced signal processing techniques in cased wells (UESTC) for ultrasonic pulse-echo and pitch-catch measurements including: a) Waveform quality assessment; b) Simultaneous inversions of mud and cement impedance; c) Simultaneous inversions of tool trajectory and mud velocity; d) Suppression of S0 mode wave; e) Extraction of TIE waveform using machine learning; f) Enhancement of TIE arrivals using machine learning; g) Imaging of cement-formation interface using RTM.
