<p align="justify"> The carbonate reservoir generally has more complex porosity and permeability relationship than silicyclastic reservoir. Efforts that can be made to help the development of this hydrocarbon field is to analyze the reservoir character in more detail using petrophysical rock type (PRT) approach. This approach is used by combining geological elements such as sedimentary environments, petrophysical properties of rocks, and the fluid flow in them that is reflected by capillary pressure and water saturation. This method is expected to be one method that can increase the production of hydrocarbons optimally in the Xena Field. <br /> <br /> The object of research from Xena Field is Zone A2 which is part of the Parigi Formation. The Parigi Formation is one of the main reservoirs of hydrocarbon producers in Xena Field. The data that be used in this research are routine core (RCAL) data on JLB-07, JLB-08, JLB-02, JLB-23 wells, wire log data (gamma ray log, resistivity log, density, neutron log) of 30 wells and 2D seismic data. Deposition facies at Xena Field is divided into 2 facies, those are platform interior and sandshoal. <br /> <br /> Rock type (RT) identification has been done using Flow Zone Indicator (FZI) method. Rock types in Xena field can be divided into 4 rock types, those are RT 1, RT 2, RT 3, RT 4. RT 1 is able to flow the best fluid and RT 4 flow the worst fluid. The reservoir property modeling include rock type is controlled by facies model. Sandshoal facies associated with RT 1 and RT 2. Interior platforms associated with RT 2 and RT 3. <p align="justify">
