Cement Bond Evaluation

The Radial Cement Bond Tool utilizes a single transmitter, an eightsegment receiver at 3foot spacing and a single receiver at 5foot spacing, to accurately measure the quality of the cement bond. The segmented receiver provides a radial distribution map of the cement bond quality as well as an indication of channeling behind the casing.
