FIELD: physics; geophysics.
SUBSTANCE: invention relates to geophysics and can be used to interpret seismic data. According to the present disclosure, seismic attributes are computed and attributes relating to the classical elements of a hydrocarbon system, namely reservoir, seal, trap, source, maturation, and migration, are selected. Preferably, the attributes are computed along structural fabrics (1) of the subsurface region and are smoothed over at least tens or hundreds of data voxels. The resulting geologic attributes (2) are used to analyse the data for elements of the hydrocarbon system and/or recognition of specific plays, and for ranking and annotating partitioned regions (3) of the data volume based on size, quality, and confidence in the prospectivity prediction (5).
EFFECT: high accuracy of obtained data.
