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.

Strategies for data acquisition using ultrasonic phased arrays [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018 Ultrasonic phased arrays have produced major benefits in a range of fields, from medical imaging to non-destructive evaluation. The maximum information, which can be measured by an array, corresponds to the Full Matrix Capture (FMC) data acquisition technique and contains all possible combinations of transmitter–receiver signals.
