The paper analyzes how the use of additional information obtained thought the borehole gravimetric measurements affects the accuracy of determining the parameters of the medium when evaluating elastic impedances in the framework of AVO-analysis. The possibility of increasing the accuracy of seismic survey results in the procedure for determining elastic parameters through the use of borehole gravimetry data has been demonstrated.

The seismic field of the Triassic deposits of the sedimentary section of the Barents Sea is characterized by numerous reflections of increased intensity. These reflections are due to the Jurassic-Cretaceous basaltoid magmatism. On the case of the Ledovoe field, the features of the waves propagation associated with the intrusions – multi-tiered sills are shown. Regularities in the distribution of increased seismic time thicknesses of the mapped sills are revealed, and their relation to faults is established.

A new approach to mass-spectrometric determination of the combined isotopic composition of methane has been put forward. The approach is based on the preliminary on-line conversion of methane to methanol in corona discharge and selective chemical ionization. The approach provides means to lower requirements for equipment, consumables, and operation conditions and offers a challenge to develop a new field method.

The paper proposes a scheme of numerical experiment to assess the quality of interpretation of logging signals using a digital model of the oil reservoir, including geological, petrophysical, and physical parameters of the environment and interrelated modeling in the ATLAS MPhM system of physical processes occurring in the near-well space. The confidence intervals of oil saturation obtained as a result of interpretation of noisy synthetic logging curves for models with low and high resistivity are estimated.

The issues of choosing materials for creating physical models into seismic exploration are considered. The main attention is paid to the correspondence of the acoustic parameters of the materials used in the preparation of the model to the properties of the rocks of the real medium. A technique is proposed for measuring the attenuation coefficient in materials that serve as the main elements of the formed physical model.

The world experience of using electrical exploration methods in the study of technogenic bodies is considered, in particular: determining the zoning of tailings, groundwater migration routes and the stability of dams. The ongoing research demonstrates the high efficiency of combining the methods of geophysics, geochemistry, and hydrology. On the example of mining dumps located on the territory of the Kemerovo region and the Republic of Tyva, the achievements of the interdisciplinary team of the IPGG SB RAS are shown. The use of electrical resistivity tomography and magnetic prospecting in combination with geochemical mapping and gas survey made it possible to reveal the internal structure of tailings and dumps, outline watered horizons, and determine the transport of highly mineralized solutions to groundwater. Obtained results became the basis for creating a methodology for a comprehensive study of tailings and dumps, assessing the danger of technogenic bodies, and developing methods for minimizing their impact on the environment and the population of settlements.

The paper considers the estimation of the attenuation parameter using the method of spectral ratios. Based on model and real data, it is shown that in order to obtain stable estimates, it is necessary to have the most complete information about the structure-velocity characteristics of the medium. Also, an important aspect of data preprocessing is to take into account changes in the waveform associated with the transmission medium.

In the urban conditions in Salekhard city, a complex of methods, including electrical resistivity tomography (ERT), ground penetrating radar (GPR), a seismic survey on refracted waves (REF), on surface waves (MASW) and the standing waves selection, was tested on solving geocryological problems and monitor the permafrost at the building base. As a model object, a residential building on a pile foundation, built according to the principle I and equipped with a continuous geothermal monitoring system, was chosen. It has been established that the ERT, REF, and MASW methods are ineffective in the conditions of a reinforced concrete pile foundation in a grillage and a concrete floor screed with a layer of loose bulk soil under it. The best result was shown by GPR at frequencies of 150 and 400 MHz and seismic exploration with the standing wave selection. A combination of these methods is recommended for determining the upper permafrost boundary under buildings, determining the actual piles-length, the quality of their fixing, assessing the water content of soils in the area around the piles, and establishing the residual building life.
