TLDR
There have been major improvements in instrumentation, field survey design and data inversion techniques for the geoelectrical method over the past 25 years as mentioned in this paper, which has made it possible to conduct large 2D, 3D and even 4D surveys efficiently to resolve complex geological structures that were not possible with traditional 1-D surveys.About:

TL;DR: In this article, an experimental methodology that combined capacitive resistivity imaging (CRI), electrical resistivity tomography (ERT), and micro-seismic event recording was used to monitor freeze-thaw of six blocks of hard and soft limestones under conditions simulating an active layer above permafrost and seasonally frozen rock in a non-permafrost environment.

TL;DR: In this paper, electrical resistivity tomography (ERT) data were collected along three different lines of 315m of length each, and the expected vertical penetration depth was 60 m. The results of these results could be used to improve the management of karst groundwater resources in Amdoun (NW Tunisia) complex terrain.

Inside the polygonal walls of Amelia (Central Italy): A multidisciplinary data integration, encompassing geodetic monitoring and geophysical prospections
Maurizio Ercoli,Raffaella Brigante,Fabio Radicioni,Cristina Pauselli,M. Mazzocca,Gino Centi,Aurelio Stoppini +6 more
TL;DR: In this article, a portion of the ancient polygonal walls of Amelia, in Central Italy, was investigated by combining several non-invasive techniques such as Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT), specifically adapted for this study, Laser Scanning and Digital Terrestrial Photogrammetry, integrated with other geomatic measures provided by a Total Station and Global Navigation Satellite Systems.

Non-invasive detection of fractures, fracture zones, and rock damage in a hard rock excavation — Experience from the Äspö Hard Rock Laboratory in Sweden
TL;DR: In this paper, geophysical surveys were performed at two locations within the Aspo Hard Rock Laboratory in Sweden, where Earth resistivity (RES), induced polarization (IP), and ground Penetrating Radar (GPR) data were collected using a variety of survey parameters; Light Detection and Ranging (LiDAR) data was collected as a reference for surface structures, surface topography, and site geology.

The electrical resistivity log as an aid in determining some reservoir characteristics
TL;DR: The usefulness of the electrical resistivity log in determining reservoir characteristics is governed largely by: (1) the accuracy with which the true resistivity of the formation can be determined; (2) the scope of detailed data concerning the relation of resistivity measurements to formation characteristics; (3) the available information concerning the conductivity of connate or formation waters; and (4) the extent of geologic knowledge regarding probable changes in facies within given horizons, both vertically and laterally, particularly in relation to the resultant effect on the electrical properties of the reservoir as mentioned in this paper.
Book
An Introduction to Applied and Environmental Geophysics
TL;DR: The first edition of the book as mentioned in this paper contains case histories, and descriptions of geophysical techniques not previously included in such textbooks, but the level of mathematics and physics is deliberately kept to a minimum but is described qualitatively within the text.
