We selected seismograms from a 3D seismic survey acquired at the Waggoner Ranch, Texas to characterize the distribution of porosities in each lithofacie. Porosity images were obtained using cokriging and the facies using the Self-Organizing Map (SOM) technique. The reservoir geology is a sand and shale sequence with small amounts of limestone as markers. The SOM uses reflection attributes that are able to capture the three geological units. The seismic lines are first converted to impedance and… Expand
