Combining multi-source data to identify the paleochannel system in the saltwater intrusion area
TL;DR: In this paper , an electrical model of the paleochannel was constructed by combining multiple sources of data, including numerical simulation data, hydrochemical data, and stratigraphic data, which provides a reference for the interpretation of the porthole using ERT data.

Hydraulic Parameters Estimation Using 2D Resistivity Technique: A Case Study in Kapas Island, Malaysia
TL;DR: In this article, two resistivity profile lines were measured in an island that is characterized by complex geology, and rock and soil samples were collected along the resistivity lines, together with water samples for laboratory analysis which includes determination of the electrical properties of the samples using an inductance-capacitance-resistance (LCR) meter to calibrate the results.

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.
