Three Component Downhole Magnetic Surveys. A Case Study of the Namaqualand Copper District

The three-component downhole magnetic probe from IFG Corporation was originally<br>designed as a borehole deviation survey tool. However, because of the accuracy and<br>sensitivity of the sensors, it quickly evolved into a multi-purpose geophysical exploration<br>tool that can supply information for the three components of the Earth‘s magnetic field,<br>the magnetization of the surrounding rock and the deviation of the borehole path during<br>a single run.
