Sequence Stratigraphy as a Tool for Geological Interpretation of Seismic Data - Case Studies

Sequence stratigraphy was introduced and applied to geological studies as a tool for prediction of reservoirs, seals and source rocks. It integrates regional geological, well and seismic data. Current paper presents the results of case studies in different sedimentary basins of Russia. Sequence stratigraphy was applied to the fields and areas with different structural and depositional paleoenvironments. It proved to be most effective in the The Western Sybirian clinoform neokomsky formation (K1). The approach, used to identification of sequence boundaries, maximum flooding and transgressive surfaces, was based both on seismic and well data. The most favourable location of reservoirs was predicted in fan and channel complexes of lowstand sequence tract and shelf bar complexes of highstand sequence tract.
