A case study of stratigraphic and lithologic interpretation of thin reservoirs through an integrated approach

To improve modeling, understanding and drilling of new wells in thin reservoirs, we developed an advanced quantitative methodology that integrates 3D poststack seismic data, impedance logs, and geologic knowledge. The approach uses well-log analysis, seismic wavelet estimation and well-to-seismic calibration, horizon tracking, instantaneous and multidimensional attribute analysis for structural mapping, stratigraphic interpretation using window-based attributes, and inverted acoustic impedance obtained from 3D poststack stratigraphic inversion.
