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:

Application of a generalised MPK model with data fusion approaches for landslide risk assessment
TL;DR: In this article, an explicit petro geophysical transfer function between suction and resistivity is presented, which was derived from the Waxman-Smits electrical resistivity model and the Van Genuchten equation for soil water retention curves.

The use of a semi‐structured finite‐element mesh in 3‐D resistivity inversion
TL;DR: In this paper , an adaptive semi-structured mesh that combines structured and unstructured meshes was proposed to calculate the electric potential for 3D resistivity inversion algorithms, which reduced the calculation time by more than three times compared with a structured mesh.

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.

Occam's inversion to generate smooth, two-dimensional models from magnetotelluric data
TL;DR: In this paper, the authors propose an extension of the existing 1-D algorithm, Occam's inversion, to smooth 2-D models using an extension to the existing Occam inversion.
