Some particularities of CDP 3D seismic data processing at the Verkhnechonskoye oil, gas and condensate fi eld are reviewed in the paper. Seismic earth modeling was used to fi nd criteria of analyzing refl ection amplitudes in different stages of processing workfl ow. As a result of the research the special technology of dynamic seismic data processing was developed to correct and compensate infl uence of sedimentary cover conditions on the target horizon amplitude. The technology comprises several stages and includes elements of interpretation in standard workfl ow with true amplitudes correlation saving.

Key words: CDP 3D seismic exploration, processing, average amplitude, correlation analysis.
