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.

This paper demonstrates the effectiveness of this methodology through a case study of producing reservoirs with Miocene basal sands, which are thin and discrete in nature. In addition, lateral facies (frequently observed in these producing...
