wells. Study distribution of reservoir is needed so development can be done effectively. Sandstone AF-07 is one of the existing reservoir on the Field Hadison. Identification of sequence stratigraphy revealed that there are four times maximum flooding surfaces (MFS). They are MFS-A, MFS-B, MFS-C and MFS-D. Reservoir AF-07 is at interval between MFS-B and MFS-C which prograded delta stacking pattern. Facies identification from core show delta depotisional environment with facies association Ditributary Channel with litofacies St, Sp, Bl, Fl and Delta Plain Shale with litofacies Fr, C, dan C4. This layer was deposited on Upper Miosen in Lower Delta Plain environment and deposition direction to southeast. The structural geology control is growth fault which reactivated during Miosen-Pliosen and an anticline formed in Late Pleistosen. The calculation resulted about 2,01 MMstb of oil and 24.79 MMScf of natural gas. Hydrocarbon trapped in an anticline in research area |
