Casing Inspection

The small diameter of the ICL compared to other Casing-Inspection tools is a great advantage, because it is not necessary to pull tubing out of the well. This can be a great cost-saving. The graphs below show the tool response characteristic when used in the Casing Inspection mode and with the Digital Output option. The variation of digital data from the nominal value is plotted against casing weight. The second chart shows the effect of an additional outer casing.
