“…The SBT can only evaluate the cement bond quality at the casingcement interface with azimuthal resolution of approximately 60° and VDL is used to determine the cement bonding at the cement-formation interface. The isolation scanner (Schlumberger) is a new-generation cementing evaluation tool that combines ultrasonic reflection and refraction with signifi cant improvements for lightweight cementing (van Kuijk et al, 2005;Bellarbarba et al, 2008;Tang et al, 2012;Loizzo et al, 2013); however, the isolation scanner with mechanical rotation and the subsequent data interpretation are complex to use and perform. The acoustic wavefield and detection methods are being studied theoretically to better evaluate the cement bond quality (Tubman et al, 1984(Tubman et al, , 1986Song et al, 2012;Duan et al, 2014;He et al, 2014).…”

We developed a novel cement evaluation logging tool, named the azimuthally acoustic bond tool (AABT), which uses a phased-arc array transmitter with azimuthal detection capability. We combined numerical simulations and fi eld tests to verify the AABT tool. The numerical simulation results showed that the radiation direction of the subarray corresponding to the maximum amplitude of the first arrival matches the azimuth of the channeling when it is behind the casing. With larger channeling size in the circumferential direction, the amplitude difference of the casing wave at different azimuths becomes more evident. The test results showed that the AABT can accurately locate the casing collars and evaluate the cement bond quality with azimuthal resolution at the casing-cement interface, and can visualize the size, depth, and azimuth of channeling. In the case of good casingcement bonding, the AABT can further evaluate the cement bond quality at the cementformation interface with azimuthal resolution by using the amplitude map and the velocity of the formation wave.
