Rock-fabric/petrophysical classification of carbonate pore space for reservoir characterization

The important geologic parameters that can be described and mapped to allow accurate petrophysical quantification of carbonate geologic models is defined. All pore space is divided into interparticle and vuggy pores. A description of vuggy pore space that relates to petrophysical properties must be added to the description of interparticle pore space to complete the petrophysical characterization. Vuggy pore space is divided into separate vugs and touching vugs on the basis of vug interconnection. Separate vugs are fabric selective and are connected only through the interparticle pore network. Touching vugs are nonfabric selective and form an interconnected pore system independent of the interparticle system.
