Geodynamic zoning of the Sea of Azov shelf and environmental problems in oil and gas production.

Abstract

The algorithm for identifying geodynamic zones was based on an analysis of geological, geophysical, and tectonic maps of the Sea of Azov, a bathymetric map and oil and gas prospectivity data, structural maps for reflecting horizons in the Cretaceous, Maykop, Sarmatia, etc., geotechnical zoning maps, and power maps, taking into account the features spectral characteristics of the water surface in satellite images.The spatial distribution of the surface temperature of the Sea of Azov was obtained using the MODIS AQUA survey equipment for the last three years (months - April, May, September).In order to clarify the boundaries of geodynamic zones, intellectual integration of geospatial data was carried out, the result of which was the location scheme of geodynamic zones on the shelf of the Sea of Azov. The creation of a model for generating a useful signal on satellite images of the sea surface with the aim of assessing their environmental safety during oil and gas production is justified.Based on the results of processing all the available information, the following was established: the greatest environmental risks may arise during the exploitation of deposits in the southern geodynamic zone, it is safer, and in the environmental respect, oil and gas exploration is the geodynamic zone in the central part of the sea. The safest zones include the northern coastal shelf zone.
