Introduction. The subject of the study of this work is the deposits of the anomalous section of the Bazhenov formation (ASB) of Western Siberia, the disturbed occurrence of which was recorded by 2D, 3D seismic exploration and borehole data at many fields of the Frolov oil and gas region. The research area unites the company’s assets in the KhMAO and the Tyumen region, which are part of the large hydrocarbon cluster “ZIMA”. Aim. In order to typify various complexes of rocks of the Bazhenov formation and further localization of deposits, a comprehensive core analysis, GIS and seismic studies were performed. Materials and methods. According to the results of lithological study of the core and petrophysical interpretation of logging diagrams, have been identified various types of rocks in the interval of the Bazhenov formation. According to the results of the interpretation of the seismic survey materials, contoured zones that differ in the wave pattern by different coherence of the axes of common phase. The revealed differences in seismic sections compared with borehole data and geological bodies mapped based on the obtained patterns. Results. Based on a comprehensive interpretation of the core, GIS and seismic studies, established the zonality of the distribution of various types of deposits of the Bazhenov formation, the relationship of the development of ASB zones with the introduction of Early Cretaceous sedimentary bodies and showed the introduction of detrital material from the overlying rocks. Conclusions. The authors of the article conclude that the development of anomalous sections of the Bazhenov formation involves several stages of the introduction of landslide bodies of overlying rocks, according to the gradation of Neocomian clinocyclites in the north-west direction. Within the study area, mapped three large landslide bodies in the Bazhenov formation interval, each of which was formed an internal zonality and because of the introduction of rocks from the overlying interval.

Summary Today we can clearly see that the world's leading oil companies strive to improve not only the quality of explorations but also tighten industrial and environmental safety requirements to this work. Green Seismic is a complex of methodologies, technical means and organizational measures applied to seismic explorations to ensure they efficiently achieve the following goals: Narrowing the width of the signal reception and excitation linesReducing personnel injuries in the course of seismic surveysGetting access to restricted exploration areas and improving seismic data qualityReducing the number of seismic crew personnel The need for this project is caused by the technology challenges faced by Gazprom Neft's seismic operations. These challenges, that significantly complicate seismic work when it is performed by standard methods, include a large number of industrial facilities, infrastructure networks, residential areas, agricultural lands, thick forests, mountainous terrain and everything else that makes it impossible to deploy seismic crews, does not allow achieving sufficient density of seismic lines, extends the time for preparation of driveways for heavy equipment, increases the risk of injury to personnel when performing tree cutting work, and generally affects the Company's image in aspects related to the introduction of environmentally friendly technologies. The main purpose of this project is the establishment of an innovative technology that would allow the Company to remove or minimize negative factors of seismic operations performed by standard exploration methods.
