3d inversion capability of electrical soundings data in water area conditions

(Tatarkin A.V. Filimonchikov A.A. )

The experience of applied 3D inversion for interpretation of vertical electrical sounding data in water area is considered. The questions of using this procedure, when observations are made at the interior points of medium, are investigated. Correction methods of measurement results in these conditions are offered. The comparative analysis of one-dimensional and threedimensional results is performed. The example of 3D inversion using for geophysical data interpretation within geological engineering survey is given.......

The results of application of nanoelectrical logging for estimation of oil saturation in cased bore hole

(Nekrasov A.S. Chernyh I.A. Guliaev V.V. Ustinova Yu.V. )

The results of definition of current oil saturation by nanoelectrical logging are presented. The comparison of definition of current oil saturation using standard dependencies of porosity and oil saturation parameters from coefficients of porosity and water saturation and saturation by special on impulse neutron-neutron logging is presented. The comparison of electric resistance defined in open hole and resistance by nanoelectrical logging defined in column is suggested in wells cased before perforating. The method of nanoelectrical logging must admit perspective in terms of obtaining information involving more data for statistics.......

Electric surveys in conditions of urbanized territories

(Kolesnikov V.P. Laskina T.A. )

The substantiation and development of electric methods complex are considered, which allows to estimate the physical condition of rocks and the dynamic of it’s variation in industrial zone. Instances of it’s effective applying for geological structure investigations with a purpose to control and predict possible negative physical-geological processes are shown as the example of a salt deposit.......

Technique of integration of geophysical methods at creation of velocity model of near-surface geological section

(Mityunina I.Yu. )

Technology of construction of geologic-geophysical model by complex interpretation of CDP data, high-precision gravity measurements and vertical electrical sounding is suggested. Technology is realized on a base of ArcGIS 10 (ESRI) with additional module Target (Geosoft Inc.). Model created makes it possible to correct promptly near-surface effects on processing and interpretation of geophysical data.......

Gravity investigations the verkhnekamskoe potash deposit

(Bychkov S.G. Prostolupov G.V. Shcherbinina G.P. )

The results of gravimetric survey conducted to study the density structure of the Verkhnekamskoe potash deposit strata are presented. It is shown that the modern processing and interpretation methods of high-precision gravimetric researches, implementation of monitoring and ground and underground gravity surveys significantly increase opportunities for gravity studying of geological structure of the salt and salt-wide layers. Examples of gravimetric survey on emergency mine area are given.......
