Rapid Inversion of Data from 2-D and from 3-D Resistivity Surveys with Shifted Electrodes
TL;DR: In this article, the smoothness-constrained least square optimization method is modified to include the electrode positions as unknown parameters to be determined, which greatly improves the accuracy of the recovered electrode positions compared to the use of a homogeneous earth starting model.

True 2-D resistivity imaging from vertical electrical soundings to support more sustainable rural water supply borehole siting in Malawi
TL;DR: In this paper, an advanced resistivity method was adapted for developing country use and demonstrated in Malawi to improve borehole siting for rural water supply, which allows single or multiple operators to acquire the multiple vertical electrical soundings (VESs) required that are inverted together in 2D, to give a true cross-section of subsurface resistivity.

TL;DR: In this article, a theoretical study and field test are presented using the direct current (DC) method to evaluate the impact range of coal seam hydraulic measures, and the results showed that coal conductivity was enhanced by high pressure water in the coal seam, and after hydraulic fracturing, the boundary of the apparent resistivity decrease area was the boundary impact range.

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.
