Combining geostatistics and multi-attribute transforms: a channel sand case study, blackfoot oilfield (alberta)

摘要

In this paper, we combine the methods of geostatistics and multi-attribute reservoir parameter prediction (the multi-attribute transform) for the integration of seismic and well log data, and illustrate this new procedure with a case study involving the prediction of porosity at the Blackfoot oilfield, central Alberta. The objectives of the survey were to delineate incised, valley-fill sediments within the Early Cretaceous Glauconitic Formation at this field and to distinguish between sand-fill and shale-fill. The input consisted of twelve porosity logs together with a 3D seismic volume and the inversion of this volume.
