Application of Electrical Resistivity Data Sets for the Evaluation of the Pollution Concentration Level within Landfill Subsoil
TL;DR: In this paper, the electrical resistivity method was used to investigate the potential pollutant migration pathways within areas of existing and former landfill sites, and the study was aimed at pollution spatial migration analyses and the interpretation of results, for further design of the reclamation and restoration plans.

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.
