FIELD: physics.
SUBSTANCE: method involves performing geologic and seismic survey, as well as remote optical gas analysis using remote lidar. During gas analysis, a spectral image of the set of chemical components in the surface layer of the atmosphere is formed. Spatial selection of the spectral image of the area on given tracer substances is performed. The detected gas components are compared with the composition of the reference mixture of hydrocarbon components which corresponds to the geographical position of the area and the deposit. The area is mapped with spatial differentiation on the relief of the obtained spectral image of the probed area. The spectral image of the region of the authentic hydrocarbon deposit is selected on the map. A family of points with the measured concentration of heavy hydrocarbons is determined.
EFFECT: high accuracy of searching for hydrocarbons, low cost of search operations.
