Complex methodical decisions in mining seismic

(Sanfirov I.A. Babkin A.I. Yaroslavtsev A.G. )

Some different mining seismic researches are presented. Each of them connects with real target in ensuring of the mines safety. They are: mapping of the local potash salt substitution, estimations of the fractures zone sizes around working out space, checking of the rock massif state not far from of the shaft boundaries. These researches are based on joint using reflection seismic waves with spreading in different directions. These waves can be different types -P and S, different frequency: from hundred Hz until thousands and result of the surface seismic researches above mine with seismic taking into account too. Some case histories are presented.......

Comparative analysis of treatment results of measurements of dipole acoustic logging program «Sonata» and «LogPWin»

(Utochkin Yu.V. Mekhonoshina E. Gubina A.I. Baburov V.N. )

The article is devoted to the comparison of the two programs modules for the dipole measurements processing thet are realized in the program «Sonata» and «LogPWin». For the azimuthal anisotropy estimation in the «LogPWin» out of data methodology of the interpretation of the wave patterns as scalar observation is used. The efficiency of the new methodology developed by LLC «FXC-PNG» and realized in the «Sonata» is presented in comparison with the CMI and MSD data in open hole and while hydraulic fracturing.......

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.......
