Abstract

Seismik Acoustic impedance inversion and seismik multiattribute are the seismik methods that can be used to mapping the distribution of sandstone reservoir. By using these methods, we can distinguish between sandstone and shale in Talang Akar Formation at RM Field, South Sumatra basin. Both of these methods will be mutually comparable to each other in order to obtain more valid results in mapping of sandstone reservoirs. There are 3 types of seismik acoustic inversion that used in this research, which are bandlimited, modelbased, and linear sparse spike. seismik multi-attribute that used in this research is multiatribut linear regression to mapping neutron porosity volume and density. As the results of seismik acoustic impendance inversion, the value of sandstone reservoir is 27000 - 30000 g / cc * m/s. As the results of neutron porosity multiattribute, it has a value of 32-35%, and the value of density multiattribute is 2.4 - 2.6 gr / cc, and effective porosity value is 19 - 20%. Based on the Acoustic Impedance (AI) volume map, PHIE, NPHI volum, and density volum, the porous rocks located in SE-NW.
