Abstract
This invention aims to improve the a coil system used for the calibration of extra-deep reading downhole resistivity tools. The currently used coil-system is mounted around the tools, in addition a shielding cage is mounted around the antenna / coil system. This can be replaced by a system consisting of multiple smaller coils placed outside of the tool, significantly improving the required time to setup the system and quality of the achieved calibration.
