Abstract. Analytical solutions of electrodynamic problems related to small class [2],
allowing us to find solutions analytically. One such problem is the direct problem in environments with axial symmetry. The relevance of such problems occurs both when used in the development of downhole tools to solve specific geologic problems and data interpretation of well logging.

GEONOM techniques were applied to the interpretation of detailed gravity over the
Shershnevskoye oil deposit area in order to confirm their capability and utility in a complex geological setting. The application was in fact successful, with the extraction of significant information pertaining both to the structure of the salt strata as well delineation of the Upper Devonian oil-bearing reefs.

Abstract. Modern requirements for seismic data processing and interpretation has fallen outside of structural imaging, characterization of improved reservoir saturation properties. Services players are facing a challenge related to lithology, reservoir qualities (permeability and porosity), saturation type, oil-and-gas thickness prediction. This means the necessity of rather exact solutions- not qualitative-based approach to section parameter determination. The absence of low-frequency components of the signal as a result of inversion made it impossible to obtain a reliable estimate of elastic impedance absolute values. And as a consequence – inability to obtain absolute values of predicted parameters (such as shale volume, porosity, permeability, etc.). The main problem is that a low-frequency component (in an explicit form) in the signal obtained from seismic sensors is either not available (hardware filtering in seismic module) or excluded from the spectrum during processing. As part of the interpretation study of physical sense of wavefield special attributes our experts have directed attention to an interesting fact: in the points of some wells the integral of waveform envelope after total filtering (by complex combined filter) almost completely coincides with acoustic impedance curve on the basis of production logging data (after applying low frequency filter). Further studies have showed that the observed effect is due to the nonlinearity of geological environment. Thus, it was recognized that in a special case the nature of nonlinearity is equivalent to amplitude modulator ( ). And a signal envelope (Gilbert transform, for example) is nothing but signal detector. Thus, the calculation of the signal envelope after total filtering makes it possible to obtain the missing part of low frequency range of spectrum. Keywords. seismic, non-linearity, low-frequency, inversion, absolute values.

In the article we present results of the first experience of synthesis of renewed deterministic models of interpretation and simplest statistical methods for the definition of positions and depths of recommended boreholes with the object of development of gravity sources. In the suggested algorithm we use ideas of the guaranteed approach and constructions of generalized assembly algorithms for finding of single interpretative variants in the presence of different prior information.

An approximate method for the continuation of potential fields is devised in the report. The method is based on the optimal algorithms for the approximation of the classes of functions
),(, MQr and ),(, MBr [1,2]. Recall that the class of functions ),(, MQr includes solutions of elliptic equations and potential fields created by different gravitating masses [3]. On several model examples the following advantages of the proposed method over the standard method (that is built on uniform mesh) are demonstrated: 1) the precision is one order higher; 2) the difference scheme keeps the stability while the difference scheme on uniform mesh loses the stability; 3) approximately two times smaller number of operations in comparison with standard method. . zxOx 21 ,

SUMMARY. Analysis of the anomalous magnetic field allowed to divide the original field into components and create a model of magnetically active layer which consists from three structural layers of different genesis. The lower part of the structural floor caused by disorders in the crystalline basement, and can be formed by the deep faults of itself in the basement, and also by the ledges projections of the crystalline basement, developed along the faults lines. The average structural level generated by two large systems of dikes: Snopinskoy and Ust - Vyisky included in Mezenskaya trap province. The age of those dike systems determinates as the interval from the top of Upper Carbon till the lower parts of the Kazan stage of the Upper Permian, for Snopinskoy system, and from the Riphean till Late Carbone for Ust - Vyisky. The upper structural level formed by the strong magnetic sources of anomalies, located in the upper part of the sedimentary cover . Generation of this horizon connected with the latest phase of magmatism, that established the upper level of Mezenskogo trap field, which age determinates as the Late Permian or possibly Early Triassic [VA Bush , 2009].

SUMMARY. Area of negative polarity was distinguished and contoured on base of magnetic field analysis. This area is confined to subsided part of the Vityaz Ridge and corresponds to area of crust extension and destruction. Inverse problem solutions lead to conclusion that extension and destruction of the crust was accompanied by intrusion of magmatic matter during inversed polarity epoch. Presence of local positive magnetization anomalies in this area may be explained by superimposed volcanic activity associated with subsequent stage of magmatism related to positive polarity epoch.
Basing on magnetic field character and bedrock dating we suppose that extension zone in the fore-arc area was formed in Late Oligocene. This period approximately corresponds to the beginning of Kurile Basin opening and volcanic arc forming.

The article outlines the rationale for the use of high-precision gravity prospecting for
underground gas storage monitoring (UGS). The article proposes a technique of UGS monitoring which is based on modeling of complex geological environment using geological-geophysical data. The software used is PlayGround, EvDynInversion and GeoVIP processor developed in the mathematical modeling laboratory of Ukhta State Technical University. The solution of inverse problems of gravity prospecting involves the use of dynamic evolutionary principles of optimality.

Abstract. The analysis of geodynamic environment and heat flow data is performed in the
study region where three large lirthospheric plates including the Eurasian, North America and Pacific plates, and a number of microplates, such as the Okhotsk, Beringia and Amur plates, are converging. In areas of plate interaction, heat flow values appreciably exceed background values. This implies that in Northeast Asia areas of lithospheric plate interaction exhibit high seismicity as well as increased heat flow values.

3 « », , In this work we aim at determining appropriate set of parameters for three-dimensional inversion of potential fields data using models which contain structures and contrasts typical for real-world data collected in areas of interest. Employing a comprehensive series of tests and different noise models enables us to carry out systematic resolution and sensitivity analyses and helpreduce ambiguity when working with real data inversion.

Abstract Based on results of magnetotelluric soundings (MTS) carried out in the northwestern part of
the Middle Amur Sedimentary Basin across its extent, the geoelectrical sections were constructed down to a depth of 5 km that exhibit a complicated structure of the basin. MT results were compared to those obtained by other geophysical methods and a good consistency of the results was obtained. Thrust fault structures with related zones of abnormally low conductivity were detected that may be promising for exploration of oil-and-gas deposits.

Gathering, analysis and re-interpretation of archival materials of electrical prospecting (TEM, MTS and MT), gravity-magnetic data, including data of aerogravity-magnetic and spectrometer prospecting of a scale 1 : 50 000 were made for the total area of 90 000 km ² within Nepsko-Botyobinskaya anteclise. Generalization of seismic common depth point method data was executed as well. Processing of the raw logging data (lateral LLD, acoustic ASL and gamma-ray GR) in 113 wells, stratigraphic subdivision and seismic boundaries linking, borehole sections construction along profiles, analysis and processing of test results with the integrated oil-and-gas parameters in two groups of productive horizons B and C (313 wells) obtaining were also carried out.
In the area there are more than 25 licensed sites of various oil-and-gas companies and 20 oil-and-gas fields, in most of which hydrocarbons are extracted.
As a result of obtained data re-interpretation, construction of consolidated maps of the geophysical parameters (such as the depth of the roof of the terrigenous Vendian (KV), the base of Vendian - the roof of the folded basement, the roof of the high resistance crystalline basement, maps of thickness of the terrigenous Vendian and conductivity of conductive Riphean formations, conductivity and resistivity of individual horizons, maps of anomalies of gravity and magnetic field and their derivatives as well as maps of various types of faults – grid 500 x 500 m) was made. A comprehensive interpretation of all the data with the purpose of oil-and-gas presence prediction in the studied area is performed. Both the traditional multifactor structural-facies approach and formalized estimates based on 50 different parameters with training on a variety of standards (groups of fields) were used for the problem solution.

Abstract. Analyzing literary publication on the geodynamic of Fennoscandya due to periodic climate glaciations and the warming the author put forward the idea of glacioisostasy connection with the formation of the anticline structures around the peninsula. The gravity, isostasy and geoids anomalies, the dynamics of the movement of the earth surface and the deflection of vertical are due to the same source – the differentiation of the lithosphere density, then they must be studied together. Key words. Fennoscandia, glacioisostasy, glaciodynamic, gravity anomalies , anticline structures

Annotation: Annotation: The example of the high-precision gravity survey at Kaluzhsko-Belskaja structural zone (SW part of Moscow syneclise) demonstrates the ability of a reliable allocation of the low-amplitude (50-60 µGal) local gravity anomalies caused by the heterogeneity of the upper-sedimentary part of the geological structure. Comparison and integrated local gravity and seismic velocity profiles (refracted waves method) interpretation are relized. The direction of further researches of opportunities of high-precision gravitation measurements is planned when studying a structure of the top part of a geological section in the conditions of development of subhorizontal structures of a sedimentary cover.

Iterative methods of the solution of the return linear problems of a gravimetry and magnetometry on the basis of analogs of filters of Wiener-Kalman for two interpretative models using division of the card of a field on two massifs of even and odd profiles are improved. The new iterative formulas providing steady and geologically the substantial decision, unlike known methods, from any entry conditions without the preliminary beginning of the decision are offered by other methods. It gives two close decisions, independent of solutions of the return task other methods. Examples of practical realization of a method for a magnetometry in the ore area on the Ukrainian board are given.

5 Geological Survey of Israel, Jerusalem, Israel, [email protected] The paper presents results of comparative analysis of coseismic and postseismic variations
of the Earth's gravity field in the regions of three recent giant earthquakes: Andaman--Sumatra, December 26, 2004, Maule--Chile, February 27, 2010, and Tohoku Oki, March 11, 2011 using GRACE satellite gravity data. In general, coseismic gravity field variations are in agreement with synthetic signals calculated using models of coseismic rupture based on seismology and geodesy. Temporal gravity field variations in the Sumatra and Tohoku regions are similar. They correspond to process of postseismic downdip propagation of coseismic rupture. Temporal variations in Maule-Chili area are different. Possible geodynamic explanation is that according to fault plane models the Earth’s crust in Maule-Chili was ruptured down to 45-50 km by the time of the seismic event.

Abstract. The article deals with the issues of Petrophysical data on crystalline rocks of the Voronezh Crystalline Massif. The spatial and geological features of the main unit were investigated with statistical methods. It is shown that for construction a model of the Earth's upper crust in the region, the density model of the crystalline basement of the Voronezh crystalline massif, should take into account.

Physical properties of polymetamorphic rocks in the north of the Urals have been studied and analyzed. Certain regularities of distribution of density and magnetic susceptibility of rocks in the sections of similar polymetamorphic assemblages have been revealed. In the result of petrophysical investigations, aimed to find additional diagnostic characters in the polymetamorphic rocks in the north of the Urals, three different types of petrophysical sections have been revealed – strongly, medium and weakly differentiated. These types of sections differ from each other vertically and laterally by the petrophysical properties of rocks.

. In this publication, factors are given that constraining the increase in gold production, gold-promising area are systematized, offered new ways of increasing the efficiency of mining activities aimed at prospecting and exploration of placer deposits. We propose the complex of geophysical investigations to solve problems arising from prospecting gold deposits of various morphogenetic types, which, depending on the tasks may include georadar sensing, electric profiling, elektrozondirovanie and magnetometric measurements.

A number of failures on mines of the Verkhnekamsky potassium deposit, which include
the flooding of the mines, led to a fresh look at the problem of geophysical safety of a Deposit development. The method of ground-underground gravimetry for the detection of weak points of the protective layer over the mines are developed, examples of its application are presented. It is shown that the modern methods of processing and interpretation of ground-underground gravity data significantly increase the information value of geophysical research and allow to successfully identify zones of increased danger of the development of productive layers.

2 – , , Abstract Results of 3-D modeling by finite-element method of the stress-strain state (SSS) of the lithosphere of the San-Andreas fault system region are presented. Elastic and elastic-plastic (Mizes and Drukker-Prager criteria) rheologies were tested, the reliable details of SSS were revealed. An optimal in sense of the level of tangential stresses max model of the lithosphere was constructed. In the latter, middle/lower continental crust and lithospheric mantle are approximated by elastic-plastic media with Drukker-Prager criteria. Calculated max are corresponding to real levels of deviatoric stresses within the lithosphere when model is loaded by weigh and movements of asthenosphere and Pacific plate.

The modern technical equipment allows us to locate the low amplitude gravity anomalies
(from the first gal). It is complicated by noise of diverse origin and requests both the high accuracy equipment and a special methodology. This work describes some characteristics of methods of the gravimeters’ field-work preparation, the analytical phase and data processing aiming to define a source of micro-anomalies.

Detailed magnetic survey of the Bronze Age archaeological fortified settlements has been
spent on South Urals. The magnetic maps Andreevskoe settlement has been received. On maps positions of the rests of external shaft, ditches and defensive walls are confidently defined. Results of magnetic survey were used for reconstruction of internal interiors of settlements. The data of magnetic survey was considerably noisy by anomalies from near-surface sources. For finding-out of details of a structure of ancient sites of ancient settlement various kinds of transformation of the magnetic data have been used. This data allows to restore an internal lay-out of sites of ancient settlement.

As a result of geophysical studies, the images of gold-ore deposits which are located bothe within the influence of deep faults and sub-vertical zones of high conductivity (Type I – deposit Natalka, Degdekan, Igumenovskoe ), and outside these areas (Type II – Butarnoe, Doroznoe, Svetloe) are developed. Based on findings, the geophysical criteria of mentioned deposits were formed. The complex analysis of deposits’ geophysical characteristics disclosed that the type I and type II deposits differ vastly in geophysical criteria, though they refer to the same mineralization type (gold-quartz).

Abstract: it is considered the problem of constructing approaches for solution of inverse
problems of electromagnetic monitoring in a frame of hierarchic structure of geological medium. It is suggested a three stage approach for interpretation of electromagnetic data, which is widely used for 3D interpretation of mapping in a frame of frequency-distance active electromagnetic method. Here we had written new integral-differential equations for the third stage of interpretation named as theoretical inverse problem solution for 2D electromagnetic field in a frame of the N-layered model with a hierarchic inclusion of the k rank.

This paper presents a new approximate-iteration neural network method of 3D inversion, allowing to solve 3D inverse geoelectrics problems on rectangular grids of optimal dimension. The total number of unknown parameters of the environment is about ~ n103. The principle of constructing the inverse problem grids of optimal dimension is based on the calculated values of the modulus of continuity of the inverse operator. An example of 3D inversion of simulated areal data, corresponding essentially three-dimensional environments are presented.

The tomography considered in the paper is carried out by downward continuation of potential field. A serious drawback of tomography is oblique (at 45º) interference from intensive field anomalies on the computed spatial distribution of the effective magnetization or density. If to continue down the components extracted from the field with iterative or median bandpass filter, then these interferences are suppressed as shown in the model and practical example.

The article is devoted to the development of scientific principles, methods and techniques of automated control of the primary data recorded in geophysical research in the wells. The decision on the termination of logging on certain well connected with the expert expressed the certainty of receiving the results of qualitative research. The author argues the need for automated detection of errors and quality control of the recorded data during or immediately upon completion of studies. A brief analysis of the symptoms of insecurity fragments record. An algorithm is proposed and discussed in detail the solution of mathematics assess the quality of data recording geophysical well with the use of iterative methods for modeling incomplete data using low-dimensional manifolds. Provides examples demonstrating the high efficiency of the iterative methods for modeling incomplete data using low-dimensional manifolds in the problem of filling the gaps of geophysical studies and the results of numerical experiments on solving the problem of data quality control electric logging.
