Results of field testing the cement evaluation tool
The Cement Evaluation Tool (CET) developed by Schlumberger employs a pulse-echo technique using eight sonic transducers to investigate the casing cement bond. The tool has been widely field tested in a clastic environment in Brunei (N.W. Borneo), across both oil and gas bearing reservoirs. Numerous comparisons of the CET with conventional CBL/VDL logs have been made. Across oil and water bearing intervals the CET is shown to compare favourably with the CBL/VDL and yields significant additional information on channeling, cement distribution, and the success of casing centralization. In addition, the accuracy of the acoustic calipers have proved sufficient to be used in assisting drilling and completion operations. The response of the tool to a microannulus has also been demonstrated by multiple runs under varying wellbore pressures.
