A rapid correlation method for petroleum population mapping within individual petroleum reservoirs: applications to petroleum reservoir description

Abstract

This chapter describes a very rapid approach to the definition of petroleum column variations in reservoir cores on a sub-metre scale. Applications of novel, thin-layer chromatography/flame ionization detector analysis, coupled with Rock-Eval analysis of core material is described, with examples from the Norwegian Continental shelf. A screening technique is described whereby compound class information obtained on several wells from a field can be quickly compared and interpreted in terms of petroleum population variation and geometry. This screening method provides data suitable for subsequent sample selection for detailed molecular analysis. The petroleum heterogeneities observed with this method can be used both to provide in-field correlations and to place more practical limits on attempted oil-source rock correlation studies. -from Authors
