H037 Z-99 CUMULATIVE SEISMIC ATTRIBUTE FOR �h Abstract 1 DETERMINATION J. DVORKIN 1 2 R. UDEN 2 AND L. HUBERT 2 1 Geophysics Department Stanford University Stanford CA 94305-2215 USA; and 2 Rock Solid Images 2600 South Gessner Suite 650 Houston TX 77063 USA Porosity in thin sub-resolution layers cannot be correctly mapped by directly applying rock physics impedance-porosity transforms to seismic impedance volumes simply because the upscaled seismic impedance often differs from the actual fine-scale values. Instead we propose to map the product of porosity and thickness or more precisely the total pore volume of the reservoir. This cumulative
