Abstract

Summary

The potential reservoirs in the Realgrunnen play in the Southwestern Barents Sea are heavily influenced by the complex burial history of the area. A combination of present day shallow reservoirs and formerly buried over

2 km deeper causes challenges when doing a geophysical reservoir characterization. Wells drilled in the area display amplitude anomalies, but majority has been water wet when drilled. By creating rock physics models and combining with AVO parameters Intercept and Gradient running an inverse modelling scheme (IRPM) in the AVO domain we try to link amplitude anomalies in the AVO domain with wireline log results to provide a quantitative seismic interpretation methodology for de-risking exploration in shallow areas of complex tectonic events.
