Seismic attributes are used for qualitative estimation of changes in the wave field performed within the analysis of seismic response characteristics. Related changes can be associated with sedimentation characteristics and structural features of the geological section. Subject of the study is Kovalivka field in the northern pre-flank zone of the western part of Dnieper-Donets basin. The aim of the study was to specify geological structure of the sub-salt Devonian sediments by means of attribute analysis of the wave field dynamic characteristics. It should be mentioned that Devonian sediments in Dnieper-Donets depression are very poorly studied by seismic and well drilling. New attempts to study Devonian formation here were caused by obtained inflows from similar Devonian reservoirs in Prypiat depression and by finding new prospects within the investigated area. The results of old seismic data re-processing have been analyzed as well as recent seismic and well data. Basing on the obtained data, the attribute analysis has been conducted and madden a prognosis of the geological section by wave field dynamic characteristics using Petrel software (Sсhlumberger). Due to performed interpretation procedures, we have specified location of faults, stratigraphic boundaries and distribution of sub-salt Devonian sediments. Also, we predicted a zone of development sub-salt carbonate sediments with possible a rifogenic origin. Significant increase of a total thickness of sub-salt formation and presence of quite thick relatively pure low-density organogenic carbonate sediments take place in Kovalivka field. It significantly increases the prospect potential of the area.
