Electrical geophysical techniques pin-pointing the bedrock fractures for groundwater exploration in granitic hard rocks of Southern India
TL;DR: In this paper , the authors demonstrated at three distinct lithological sites using integrated gradient resistivity profiling (GRP), vertical electrical sounding (VES), and electrical resistivity tomography (ERT) followed by exploratory borehole drilling and electrical logging to pin point the bedrock fractures in granitic hard rocks of Southern India.

A full-range gradient survey for 2D electrical resistivity tomography
TL;DR: In this paper, the authors proposed an enhanced version of the multi-gradient measurement technique, called full-range gradient survey, for 2D electrical resistivity tomography, which has a better pseudo-section coverage, a much smaller geometrical factor, and less noise contamination than the dipole-dipole survey.

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.
