A Method for the Full Automation of Euler Deconvolution for the Interpretation of Magnetic Data
TL;DR: A method based on Euler’s homogeneity relation for full automation of magnetic data interpretation is presented, which involves the use of first-order derivatives, independent of analytic signal (AS) and the derivatives are computed directly from the total field grid.

Coal mine underground direct current advanced detection method based on power supply of drilling rod
TL;DR: In this paper, a coal mine underground direct current advanced detection method based on the power supply of a drilling rod is proposed. But the method is not suitable for underground mining due to the high power consumption of the rod.

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.
