Asgar area is located at off-shore Jatibarang Sub-Basin, North West Java basin, north of Cirebon City. Eksploration in this area is still working until now, so there is needed more of study to estimate the hidrocarbon resources. Stratigraphy in this area, consists of formations, from older to younger are: Talang Akar, Baturaja, Massive, Main, Parigi, and Cisubuh Formations. But this study is focus in limestone of Parigi Formation. This study was based on data which consists of well log data of Asgar-1, Asgar-2, Asgar-3, Asri-1, and Asri-2, side wall core of , seismic-3D, check-shot data of Asgar-1, Asgar-3, Asgar-5 and Asri-1 wells, review of Asri-2 well biostratigrafi, review of source rock evaluation of Asri-2 well. Metodes which were used in this study was began with determine top dan base Parigi Formation boundary, well seismic tie, depelopment of carbonate analysis (used biostratigraphy, sequence stratigraphy, and electrofacies analysis), 3D-seismic interpretation, and petrophysical analysis. Parigi Formation was deposited in Late Meiocen of sub-litoral environment in two not complete system tracks there are late of HST and early of TST. The good porosity distribution in this formation is found in HST interval at the bottom of sequence boundary. There are four structural traps found in Parigi Formation which is based on depth structure map of top Parigi Formation. These traps are suggested as hydrocarbon prospects, with the rank from top to bottom are: prospect-2, prospect-1, prospect-4, prospect-3. The unrisk resources of hydrocarbon in this study area is 29.04 MMSTB oil and the risk resources is 10.1 MMSTB oil.
