The Importance of Well-Seismic Calibration for Interpreting Seismic Inversion Results

A-14 THE IMPORTANCE OF WELL-SEISMIC CALIBRATION FOR INTERPRETING SEISMIC INVERSION RESULTS Abstract 1 Seismic inversion techniques have become an integral part of the reservoir characterisation workflow. The resulting impedance data can provide improved interpretation and quantification of the reservoir rock properties but this depends on the well-seismic calibration. Without a good calibration the inversion results are at best qualitative and at worst can lead to assigning geological meaning to inversion artefacts. We discuss the importance of the well-seismic calibration within the context of the geostatistical inversion method. This method uses 3-D seismic and acoustic impedance (AI) well logs to derive
