A good petroleum system needs a good reservoir to properly accommodate. Thus it needs a good characterization to fully understand its properties, in which one of the method known is by utilizing Rock Physics Template (RPT). This method attempts to characterize a reservoir in order to predict the behavior of the reservoir, such as different porosities and water saturation. However, most of RPT technique applications are limited to granular rocks and not enough on carbonates. Although carbonates generally have good properties as reservoir rocks, it is proven to be more difficult to ascertain. The complex system of carbonates porosities often gives scatter pattern on the porosity and P-wave relationship. Therefore, this research will attempt to use RPT to model carbonate reservoir. This will be achieved by using Kuster Toksoz as the basis for carbonate rock modeling and by the help from Biot-Gassmann equation. The study object of this thesis is on Baturaja formation that is located in South Sumatra Basin. This formation is known to be a carbonate reservoir that has produced gas hydrocarbon. This thesis offers an approach on how to better understand the application of RPT on Baturaja formation. Based on the RPT modeling done in this research, some specific parameter needs to be obtained in order to develop a functional RPT model. These parameters are aspect ratio of the porosities and elastic modulus of the minerals.
