Ultrasonic Well Integrity Logging Using Phased Array Technology
Volume 9: Offshore Geotechnics; Petroleum Technology, 2023 Abstract Ultrasonic well integrity logging is an important and common procedure for well completion and plug-and-abandonment operations. Typical logging tools employ single-element ultrasound transducers. In medical ultrasound imaging, however, more flexible phased arrays are the standard.
