Characterization of the bridge pillar foundations using 3d focusing inversion of DC resistivity data
TL;DR: In this paper, the authors investigated the effectiveness of a focusing regularization technique for the inversion of direct current (DC) resistivity data for a typical engineering problem and proposed a minimum gradient support (MGS) stabilizer for providing shaper 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.
