Groundwater is a favorite topic of ours here at Advanced Geosciences. There is just so much to discuss! Not only is groundwater exploration an everyday use of electrical resistivity imaging (ERI), but understanding groundwater can reshape our relationship with an invaluable resource. This time, we want to look at groundwater discharge and the delicate balance it serves on a global scale.
The optional Time Lapse Inversion module for EarthImager™ 2D and EarthImage™ 3D is used for in-situ monitoring applications.
On our blog, we’ve covered 1D, 2D, and 3D Electrical Resistivity Imaging (ERI) surveys numerous times. We’ve made general comparisons and even compared how useful each is for groundwater exploration. One type of survey we don’t talk about is 4D ERI. Let’s talk about that today. So, what is a 4D ERI survey?

We’ve discussed groundwater several times on our blog and educational series. We’ve discussed how to find it and shared a few successful cases of finding it with ERI techniques.

We’ve covered the ASTM G57 soil test and IEEE standard grounding test on the blog before. In many cases, these standards will be your go-to solution for your soil test/grounding project. However, in some cases—the ASTM or IEEE tests show too high values so grounding wells need to be installed for power systems. Dry and arid soils typically found in desert environments can often produce these kinds of results.
