Abstract

Summary

We present an improved workflow to statistically model paramenters of geometry, facies, velocity and seismic models using outcrop, rock-plug samples, wireline logs and field seismic data. The models built in San Andres-Grayburg mixed carbonate-siliciclastic shelf margin were used to discuss chronostratigraphic meaning of seismic events at reservoir level for a mixed carbonate system. At reservoir (HFC) level, seismic interpretation of stratigraphic surfaces, lithofacies, and stacking patterns are accurate only to around λ/4 (40 m) barring from lithostratigraphic reflections, although interpretations of average trend and geometry are still useful. Well calibration is critical in reservoir modelling.
