Memory and SRO the Segmented Cement Bond Tool is designed to measure the density of the cement bond in the well annulus and to evaluate wall thickness of casing pipes in the scanning mode with the measurement results referenced to the apsidal plane of the well. The tool provides measurements in oil and gas wells with a diameter up to 12″, equipped with casing pipes of the outer diameter from 5.5 to 7″ and filled with brine solution 1,000 to 1,400 kg/m3.
The probe setup of the tool contains eight independent detectors of a large probe and one detector of a small probe on the axis of the tool.
