Multi-borehole three-dimensional induced polarization tomography method for tunnel water hazards ahead prospecting
TL;DR: In this article , a multi-borehole three-dimensional induced polarization (IP) tomography method was proposed for tunnel construction, and the results reveal that the method is capable of detecting resistivity and chargeability in regions between the tunnel's boreholes in 3D space.

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.
