IDENTIFICATION OF FRACTURED RESERVOIRS ZONES OF THE NEFTEKUMSK DEPOSITS BASED ON LINEAMENT-STRUCTURAL ANALYSIS ON THE EXAMPLE OF THE VELICHAEVSKO-MAXIMOKUMSKY SWELL OF THE EASTERN FORE-CAUCASUS

Currently, the success of prospecting, exploration and development of oil-and-gas deposits in the Neftekumsk carbonate formation remains very low. This is directly related to the fact that the requirements for prospecting geological exploration works do not use lineament analysis methods that take i...

Fault zone Structural decoding Fracturing Geodynamic processes Lineament Local platform structures Currently, the success of prospecting, exploration and development of oil-and-gas deposits in the Neftekumsk carbonate formation remains very low. This is directly related to the fact that the requirements for prospecting geological exploration works do not use lineament analysis methods that take into account the influence of deep geodynamic processes in the formation of structural anisotropy of the reservoirs properties of oil-and-gas bearing local platform structures. From this point of view, the old oil-and-gas bearing regions, including the Fore-Caucasus, remain unexplored, geological models of hydrocarbon deposits require additional reinterpretation from the perspective of the prevailing vertical mechanisms of formation of local structures and migration of hydrocarbon fluids. The article discusses the application of methods of visual structural decoding of satellite images in order to identify tectonic dislocations in the sedimentary cover of the Velichaevsko-Maximokumsky swell. The relevance of this problem lies in the fact that the methods of seismic exploration of the fault zones of the extension type (tension fault), characterized by zones of vertical fluid migration, are not detected. Unlike shear fractures, which are determined by identifying horizontal boundaries of different density layers in the cross-section using seismic exploration methods, extension type faults are detected only by correlation breaks, which are represented by intervals of a blurred wave pattern and changes in the frequency and amplitude compositions of the recording. These listed signs are not unambiguous. In order to take into account all types of fault zones within local platform structures, a system-hierarchical approach to identifying zones of lineaments (compared with multi-directional and multi-scale tectonic dislocations) is proposed. 2025-01-30T13:00:05Z 2025-01-30T13:00:05Z 2024 Статья Nikonov, A.I., Chernenko, K.I., Yeriomina, N.V.

description	Currently, the success of prospecting, exploration and development of oil-and-gas deposits in the Neftekumsk carbonate formation remains very low. This is directly related to the fact that the requirements for prospecting geological exploration works do not use lineament analysis methods that take into account the influence of deep geodynamic processes in the formation of structural anisotropy of the reservoirs properties of oil-and-gas bearing local platform structures. From this point of view, the old oil-and-gas bearing regions, including the Fore-Caucasus, remain unexplored, geological models of hydrocarbon deposits require additional reinterpretation from the perspective of the prevailing vertical mechanisms of formation of local structures and migration of hydrocarbon fluids. The article discusses the application of methods of visual structural decoding of satellite images in order to identify tectonic dislocations in the sedimentary cover of the Velichaevsko-Maximokumsky swell. The relevance of this problem lies in the fact that the methods of seismic exploration of the fault zones of the extension type (tension fault), characterized by zones of vertical fluid migration, are not detected. Unlike shear fractures, which are determined by identifying horizontal boundaries of different density layers in the cross-section using seismic exploration methods, extension type faults are detected only by correlation breaks, which are represented by intervals of a blurred wave pattern and changes in the frequency and amplitude compositions of the recording. These listed signs are not unambiguous. In order to take into account all types of fault zones within local platform structures, a system-hierarchical approach to identifying zones of lineaments (compared with multi-directional and multi-scale tectonic dislocations) is proposed.
