Abstract

Inversion and seismic multi-attribute analysis has been done to characterize sandstone reservoir on �Jatiwarna� field at Sunda Basin. This research used 3D PSTM Seismic data, three vertical well data and geological data. Inverse process done by using model-based inverse method, with the output as in acoustic impedance data volume. Acoustic impedance data and subsequent PSTM seismic data serves as an input in the multi-attribute analysis to produce gamma ray volume, total porosity and density. Map of the distribution values of the acoustic impedance volume, gamma ray, total porosity and density obtained from the process of slicing the horizon TA-12. The interpretation results showed that the orientation of distribution of sandstones reservoir in \"Jatiwarna\" field is trending north-south. The results showed that there is sandstone reservoir zone with the acoustic impedance values (20780 � 23849) ft.s-1.gr.cc-1, gamma ray (29-71) API, total porosity (10 -18) % and density (1,90 � 2,15) gr.cc-1.. Keywords : Reservoir characterization, Sunda Basi
