Rock Physics–driven Seismic Reservoir Characterization of the Siri

Quantitative interpretation of seismic using rock physics inversion, combined with simultaneous AVO inversion, may significantly improve our understanding of the reservoir between the wells, where we have more direct measurements of petrophysical properties such as saturation, porosity and mineral composition. The workflow is demonstrated on surface seismic data acquired over the Siri field, a Paleocene reservoir located in the Danish North Sea, characterized by glauconite rich, fine-grained, wellsorted sand, embedded in mud- and marl stones. The results can be used for well planning, as well as input to geological model building.
