3D Imaging Archaeological Tomb By Vertical Electric Soundings

18th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2005
Application of geophysical methods has increased to investigate near-surface horizons of interests in related to environmental and engineering geophysics because geophysical methods are cost-effective and large areas can be quickly surveyed at relatively low cost without borings and trench excavations. The most productive geophysical methods are Ground

Correlation of vertical electrical sounding and electrical borehole log data for groundwater exploration

Geophysical Prospecting, 2010
ABSTRACTWe have correlated the longitudinal unit conductance CL obtained from interpreted vertical electrical sounding data with the formation resistivity Rt and the formation resistivity factor F, obtained by carrying out electrical borehole logging. Interpreted geophysical data of eleven soundings and two electrical borehole log records are used for ...

Vertical electric sounding investigation of aquifers in the Ekpoma area of Nigeria.

Journal of the Nigerian Association of Mathematical Physics, 2008
Aquifers or water bearing formations existence was investigated in Eguare-Egoro, Ekpoma, Edo State, Nigeria by using vertical electric sounding (VES) of schlumberger array. The array was employed with minimum drilling spread of 2m and maximum spread of 500m. The need to investigate aquifer existence in Eguare-Egoro becomes inevitable because of acute

Model curves for vertical electrical sounding over 2D structures

53rd EAEG Meeting, 1991
Vertical electrical sounding is one of the most used electrical methods in Geophysical Prospecting and its application is restricted to those problems according to structures that do not differ strongly from stratified media. Even in these situations the simplicity of a near one dimensional earth approach is sometimes not reached and some important ...

On the resolving capability of vertical electric dipole soundings

SEG Technical Program Expanded Abstracts 1989, 1989
An extremely high resolving capability of both direct current (DC) and transient electromagnetic (TEM) soundings using a vertical electric dipole (VED) source is shown. In contrast to conventional surface methods, electric, magnetic and EM fields generated by a VED are sensitive to the presence of very thin layers, even in the case of moderate ...

Vertical Electrical Sounding (VES) of Chukchi Sea Ice

2018
Vertical electrical sounding (VES) surveys were performed on the Chukchi Sea ice near Utqiagvik (ne’ Barrow), AK in March, 2018, using a capacitively coupled resistivity array. The purpose of this study was to determine the effectiveness of the VES method in determining the thickness of the sea ice and potentially the depth to the sea floor.

On: “Straightforward inversion of vertical electrical sounding data”; discussion and reply

Geophysics, 1998
Abstract Reading the paper by Pravin K. Gupta, Sri Niwas, and Vinod Gaur in Geophysics, I came to the opinion that, although the proposed algorithm is interesting and may inspire interpreters of electrical data in the future, a number of misleading and even contradictory statements are present in the text. Here are two examples.

SOME IMPROVEMENTS IN THE INTERPRETATION OF VERTICAL ELECTRIC SOUNDING CURVES*

Geophysical Prospecting, 1986
ABSTRACTThe process of VES interpretation is discussed, including the following points.(a) Preliminary interpretation by means of master curves. It is shown that the positions of the auxiliary points K and Q depend on the resistivity of the substratum.

A new method of geoelectrical prospecting by vertical electric current soundings

Journal of Applied Geophysics, 1996
Abstract Some advantages and problems of a new geoelectrical prospecting method, vertical electric current soundings (VECS) are discussed. This method is based on using a new source, circular electric dipole (CED). The source is installed in the following way. One of the transmitter poles is grounded in the central point.
