Cement Bond Log (CBL) studies on foam-cemented and synthetic-cemented wells were initiated to determine the feasibility of, as well as to develop technologies for, evaluating these novel cementing services. Early CBL's on these cementing systems showed little effect on the log amplitude curve. Hence, CBL evaluations were difficult to obtain and interpret. A special sonde with a 1.3-ft (0.4-m) transmitter-to-receiver spacing was developed for this study. Sonic signal amplitudes were determined using cemented short-casing test sections. Sonic attenuation rates were correlated to compressive strengths for a range of cement densities. Experimental details of the cementing operation and logging studies are discussed. Data relating attenuation rates to compressive strengths and cement densities are also presented. Field results are discussed.
