Bravo Field is one of the productive oilfield in Indonesia which remains operated up to recent with high potential in hydrocarbon reserve, although it has been running since 1970. The Upper Cibulakan Formation (Main - Massive) is the biggest interval that contributes most of the hydrocarbon for the field. <br /> <br /> <br /> Reservoir characterization of the Upper Cibulakan Formation to be determined by facies distribution from seismic attribute data which is being processed to become porosity distribution,would be expected as one of the method that help to optimize the oilfield development. <br /> <br /> <br /> The purpose of using the seismic attribute data acoustic impedance and geostatistic method is to predict the facies distribution within the interval of Upper Cibulakan Formation, with the zone of interest in B-28 and B-29. Based on visual crossplot between Gamma-Ray log and AI log generate a fixed group of lithology. <br /> <br /> <br /> Facies and porosity property distribution process by using the seismic attribute data acoustic impedance has achieved a representative result for the Bravo Field.
