An ultrasonic nondestructive testing technique has been developed to assess the integrity of well seals. The pulse-echo inspection technique was used to evaluate the quality of the bond between a casing and a seal. The study was conducted in two phases. The first phase was conducted to develop a measurement algorithm. In this phase, a planar arrangement of casing materials and seals was employed. The second phase consisted of the design, construction, and evaluation of a probe for downhole testing.
