Abstract

Abstract. Seismic inversion and multi-attribute analysis method are used in this research to characterize the reservoir properties. Where both of these methods will be resulted an acoustic impedance volume and log property volumes. The property log volumes were created from density, porosity, Gamma-Ray (GR) and Water Saturation (Sw) log. There are 4 wells that are used in this research, they are EM-31, EM-32, EM-33 and EM-34 and a 3D seismic data post�stack time migration. Based on a map of acoustic impedance distribution, the reservoir target has an acoustic impedance value of 6.000 ((m/s)*(g/cc)) to 8.000 ((m/s)*(g/cc)). Furthermore, based on the map of the distribution of the log property, the reservoir has a density value with a range of 2.3 g/cc up to 2.4 g/cc, porosity value > 10%, the GR value of less than 100 API and Sw 50% to 55%. Thus, it can be concluded that reservoir has a lithology of sandstones, has a fairly good porosity and contains oil fluids.
