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.

Aquifers selection to aid geoelectrical methods on drilled well building near the beach

TL;DR: In this paper, the results showed that there were two aquifers types, i.e. free aquifer with resistivity was 33.9 ohm and distressed aquifer had a resistivity of 70 ohm.

Geophysical characterization of karst landscapes in Kentucky as modern analogs for paleokarst reservoirs

TL;DR: In this article, electrical resistivity tomography (ERT) and refraction microtremor (ReMi) geophysical surveys at the Green River Preserve adjacent to Mammoth Cave National Park in the Mississippian Ste. Genevieve and Girkin Limestones are providing details of karst features, including horizontal passages, uvulas, sinkholes (dolines), vertical pits or dome caves.

High-resolution shallow reflection seismic integrated with other geophysical methods for hydrogeological prospecting in the Nylsvley Nature Reserve, South Africa

TL;DR: In this paper, two perpendicular high-resolution shallow seismic and resistivity profiles were acquired to assist in imaging the near-subsurface sedimentary architecture for hydrogeological prospecting in the Nylsvley Nature Reserve along Nyl River floodplain in South Africa.

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.

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.
