Geological Model Building for Reservoir Characterization by Seismic Facies Classification

Abstract

D003 Geological model building for reservoir characterization by seismic facies classification Summary 1 This paper describes (1) a seismic facies classification based methodology to generate a deterministic geological model for reservoir characterization and (2) its application to a real case in the deep water. By two complementary seismic facies classification approaches (unsupervised and supervised) and principal component analysis (PCA) of seismic traces and petrophysical logs a petro-seismic facies map (i.e. facies defined on the basis of their own seismic character and with at the same time a petrophysical meaning) was generated providing the required geological constraint for reservoir characterization.
