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.

Geophysical Assessment of Freshwater Intrusion into Saline Aquifers Beneath Plain Reservoirs

TL;DR: Wang et al. as discussed by the authors used continuous resistivity profiling to evaluate the leakage problem of the Shuangwangcheng reservoir along the east route of the South-to-North Water Diversion Project.

Fuzzy soil quality index using resistivity and induced polarization for contamination assessment in a lead and zinc drainage irrigation field study

TL;DR: The Fuzzy Soil Quality Index (FSQI) as mentioned in this paper is constructed by analyzing resistivity and chargeability using four Gaussian membership functions to achieve an FSQI ranging from 0 to 100, where 0 denotes the lowest quality and 100 denotes the highest quality.

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.

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.
