Overview

The segmented bond tool is designed to evaluate the well cementing quality, employing the acoustic measuring principle. Typically run with the variable density log (VDL), the bond between the casing and cement and that between the cement and the earth formation are analyzed. The tool consists of six measuring arms, each covering a 60-degree sector of the circle. In operation, the measuring arms are motored open pushing the pads against the inner wall of the casing, thus providing better acoustic coupling and better measurement resolution.

Benefits

· Bond quality evaluation of the first interface

· VDL Wave Acquisition
