IVC (Integrated Video Caliper) enables real time well diagnosis. By combining best in class qualitative and quantitative sensors in a single tool string, IVC provides a unique view of well integrity issues so that you rig down understanding the issues.
IVC features a 24 arm multifinger caliper with 3mm vertical resolution and on-site reporting software, delivering real time eccentralisation and 3D plotting.
The tool string is run in the well with the downview camera operating to get an overview of the well condition and hardware. The caliper is then logged up with results displayed in real time. In this example the onsite engineer inspects the log for any potential integrity issues or anomalies using the 3D rotational facility and cross-sectional plotting.
The caliper clearly indicates a feature, but given that this is P110 casing, a split might be thought unlikely. With the ability to drop down and inspect the feature in detail using the HD e-line camera there is no doubt about the issue.
The HD e-line camera provides a level of detail unachievable from a multi-finger caliper. With both downview and sideview cameras providing full colour video, features such as corrosion, wear, deformation, splits or holes can be inspected in detail. The quantitative and qualitative measurements provide an ideal complement to each other.
