oa Seismic-facies research in the southern near-flank zone of the Dnieper-Donets basin

Seismic data acquisition and interpretation as a key method of modern oil and gas geological exploration is widely in use to build sedimentation and sequence models, detailed analysis of geological column, and the prediction of local non-anticline type lithological objects that could be potential hydrocarbon traps. Stratimagic software of Paradigm Geophysical seismic facies analysis (SFA) was applied to 3D seismic exploration data acquired the in several areas in the Carboniferous of the Dnieper-Donets Basin. This paper presents the results of SFA on the Livenska area located in the central part of the Southern Near-Flank zone of the Dnieper-Donets Basin. The purpose of the study was to map the local lithological hydrocarbon prospects in the upper part of the Bashkirian (Middle Carboniferous) sequence and to identify zones of gas-bearing sandstones distribution (B-22–23 pay horizon) in the Upper Visean (Lower Carboniferous) sequence. As a result, the seismic facies maps with a set of other maps were built for both stratigraphic intervals. They confirmed the presence of the paleo-channel in the Bashkirian sedimentary sequence and a zone of gas-bearing sandstones in the Upper Visean ones. So, it has been shown that Stratimagic software is an effective tool for the sedimentary record detail investigation.
