ZZ Resistivity Imaging Pty. Ltd.
Surface-point resistivity surveys are used to obtain detailed survey information around a known anomaly. At least one borehole is required near the point of interest.
As the figures below show, a FlashRES resistivity meter enables users to place electrodes anywhere they want. By placing electrodes on the surface and near the anomaly, users can gain a better resolution of the inversion image. This improved image quality helps users to accurately locate the anomaly.
The following images show resistivity surveys of the same anomaly measured in two different electrode configurations.
Drilling boreholes for exploration is expensive. As the following figure shows, clients can use the FlashRES to carry out surface-borehole surveys to maximise the geological information extracted from existing boreholes. This method can save users' money, as they may need to drill less boreholes.
