Geophysical exploration for oil and gas: current status and problems of import substitution.
Varlamov A.I., Gogonenkov G.N.
The paper briefly discusses the status of Russian hardware and software development for geophysical exploration. The analysis shows that in practically all the disciplines of the onshore geophysical works in Russia have the rather advanced in-house solutions. In recent years they found a certain commercial use in all geophysical operations. In terms of qualitative characteristics, Russian hardware and software products for seismic and other geophysical operations are only slightly inferior to the cutting-edge western developments. However, leading Russian oil and service companies prefer to purchase and use an expensive imported equipment even when a task can be solved using home-made software and hardware tools. In the current geopolitical situation and a sharp increase in sanctions pressure on Russia, there is a need for a substantial scaling up of domestic software and technology use and an expansion of innovative developments that are no inferior to the best imported analogues.

Cheremisina Ye.N., Finkelstein M.Ya., Lyubimova A.V.
The article presents the Russian software package GIS INTEGRO, developed by the team of Geoinformatics department «VNIIGeosystem» of FSBI «VNIGNI». We consider the basic cartographic capabilities of GIS INTEGRO, providing the preparation of the geo-information base for research projects for geology and subsoil use at all the stages. The comparison with the wide-range GIS-packages used today in the geological industry

Development of methodological and technical tools for seismic surveys support.
Iksanov A.Y., Kaplan S.A., Kozlov A.S., Lebedev E.B., Spivak Y.E.
The article presents a review of development of methodological and technical support tools for seismic surveys supervising which provide increased efficiency of field data analysis and integrated quality control. Taking into account the growth of field data amounts due to spread layout compaction (multiplication of channels, employment of swath-line modification and, in prospect, of 3D surveys), the authors propose ways of support tools development. Two components, technical and interpretative, are introduced into the quality control (a quality estimate summarized by reflected signal line-ups and a forecast of ways of geological task solution).
Tools for quality control on the basis of initial seismic records quality and brute time sections analysis are presented.
Methodical and technological aspects of full wave modeling in the processing of seismic data.
Vedenyapin O.A., Kaplan S.A., Lebedev E.B., Rok V.E.
The methodical and technological aspects of employment of full-wave 3D computer modeling in seismic studies at various stages of the geological exploration process are considered, i.e. from planning to the assessment of the correctness and quality of the results obtained at different stages. The authors analise possible ways of model construction in connection with the choice of the structure of geological medium models and with information provision for the specification of its characteristics. Approximation of real geological models in the form of individual sedimentary complexes and their target objects combined according to their level of mapping detail is proposed which provides the maximum computing performance for a given configuration of hardware.

The new technology is oriented towards the use of domestic samples of geophysical equipment and instruments: a cable-free system SCOUT registering seismic oscillations and highly sensitive seismic sensors MTSS-1001 created on the basis of innovative molecular electronic technology and unparalleled anywhere in the world.
Architectural features of GIS INTEGRO software.
An original plug-in architecture with a support technology have been created and used for the improvement of geoinformation software system INTEGRO. The technology in question can be embedded into the pre-existing application and allows to create an efficient, portable, object-oriented code for extending the application with pluggable modules. A model-driven approach is used to provide a binary interface between the host application and the extension modules, for which interface code in the programming language of choice (C++ for INTEGRO) is generated on the basis on XML descriptions. The technology defines interfaces and alogorithms used to discover extensions, and on its basis a Model-View-Controller like UI architecture was developed which allows to weaken GUI vendor lock-in for the application.
Keywords: plug-in architecture, object-oriented programming, graphical user interface, application binary interface, C++, INTEGRO.

Arbuzova E.V., Lyubimova A.V., Tolmacheva E.R
The article presents the results of the analysis of the geophysical survey coverage (profiles and wells) performed during the implementation of the quantitative assessment of HC-resources of the Russian Federation. We analyzed the current state of digital cartographic data, representing profiles and wells location, and identified the main problems that seriously complicate the practical use of such data. An original technological approach is proposed, which allows to calculate the formalized density indicators for the analyzed territory even in the conditions of the low quality of cartographic data. The implementation of the proposed approach was carried out by the authors of the article in the GIS INTEGRO. In conclusion, attention is focused on the need to change the existing scheme of conducting geological and geophysical studies to ensure its effective use for geological studies.
