well, it belongs to the group of "electrical surveying" methods in the field of geophysical exploration and most probably refers to the "resistivity method".
I found this information in 2-3 minutes, and can be as precise as I want to, because it comes from a university textbook on Geophysical Exploration.
I used no bilingual sources in my search.
In the resistivity method, artificially-generated electric currents are introduced into the ground and the resulting potential differences are measured at the surface. Devia- .................................................
