Vertical electric sounding investigation of aquifers in the Ekpoma area of Nigeria.
Journal of the Nigerian Association of Mathematical Physics, 2008Aquifers 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.

On the resolving capability of vertical electric dipole soundings
SEG Technical Program Expanded Abstracts 1989, 1989An 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 ...

Model curves for vertical electrical sounding over 2D structures
53rd EAEG Meeting, 1991Vertical 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 ...

SOME IMPROVEMENTS IN THE INTERPRETATION OF VERTICAL ELECTRIC SOUNDING CURVES*
Geophysical Prospecting, 1986ABSTRACTThe 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, 1996Abstract 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.

On: “Straightforward inversion of vertical electrical sounding data”; discussion and reply
Geophysics, 1998Abstract 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.

Reducing ambiguities in vertical electrical sounding interpretations: A geostatistical application
Journal of Applied Geophysics, 2007AbstractThe Vertical Electrical Sounding (VES) is the most widely used geophysical technique for groundwater prospecting. Howeverits interpretation has been subjected to several indistinctness and efforts are on to tackle them. Vertical Electrical Soundings werecarried out at 86 sites in a small watershed of about 60 km 2 in a granitic terrain with the

Detection of animal tissue thickness using simple vertical electric sounding (VES)
Physiological Measurement, 1997Tetrapolar linear arrays are commonly used in geophysics to explore the vertical distribution of resistivity values in a geological section of a specific point on the earth. This technique, known as vertical electric sounding (VES), uses different electrode configurations.
