Abstract

Summary

The results of testing the technology of integrated assessment of oil and gas potential prospects of exploration blocks and sites using modified methods of frequency-resonance processing of satellite images, as well as an improved method of vertical sounding (scanning) of the cross-section to determine the depth of the hydrocarbons and rocks are analyzed. Demonstration studies were carried out within a large area in the Khanty-Mansiysk Autonomous District (KhMAO, Western Siberia). Anomalous responses at the resonant frequencies of oil, gas condensate, gas, helium, carbon, hydrogen and amber (!) were recorded within the entire survey block, and the vertical channels were found, filled with (1) ultramafic rocks, (2) clastic sedimentary rocks (sandstones, clays etc.), (3) carbonate rocks (marls) and (4) salt. By a vertical scanning of the cross-section the estimates of the depths of the predicted anomalous polarized layers of oil type have been received. Additional studies were carried out at three sites within the survey block. The application of this mobile technology at the initial stages of prospecting work will allow seismic 3D surveys of enhanced detail to be carried out within mapped anomalies of the “hydrocarbon deposit” type. The use of technology to further assess the oil and gas potential of the structures, identified by seismic exploration, will provide the opportunity to optimize the location of exploratory wells. Purposeful use of technology in the search and exploration of hydrocarbon accumulations will allow speeding up and optimizing the overall geological exploration process for hydrocarbon resources.
