The Yığma Tepe of Pergamon: Internal construction of a monumental burial mound from shear wave reflection sounding and wavefield modelling
TL;DR: The Yigma Tepe of Pergamon is one of the largest known burial mounds in the Eastern Mediterranean as mentioned in this paper, but its internal structure, especially the existence and location of buried structures, remains unknown.

Localization and characterization of the southern Ulsan fault (UF) using geo-electrical imaging: Implication for seismic hazard assessment in an urbanized area
TL;DR: In this paper , electrical resistivity tomography (ERT) was used to locate the trace of the southern segment of the Ulsan fault, and to test the applicability of ERT techniques for active fault mapping in a close to the highly urbanized and complex geological environment with a slow tectonic activity.

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.
