Collimated Beams for Cement Evaluation [Slides]
This presentation discusses how there are no commercial acoustic sources that provide a collimated beam over a frequency range of 10–250 kHz in a small package that works in different media. A recently improved acoustic source – ACCObeam, however, is much more powerful than its predecessor (which was based on nonlinear acoustics). This presentation also demonstrated imaging capabilities of the system, in both open and cased-borehole, for different induced defects (groove, detachment, fluid-filled void pocket, casing). Future R&D includes refining and enhancing the capabilities of the 3D imaging system for more realistic environments, extending investigation range beyond the wellbore casing, and identify new applications.
