T The study area located at “PIT” Field, Talang Akar Formation, South Sumatera Basin. This study focus on facies analysis based on well log data dan calculation of reserved hydrocarbon in place. Based on stratigraphic correlation, there are four sequences in this area. The layers that become focus study are Hana 2’s layer and Hana 4’s layer that belong in one sequences (sequence 4). In this area, Hana 2’s layer is deposited as sediment distributary channel with relative deposition direction south west-north east. This layer contains oil with porosity values amount 0.13 and estimated contains reserved of oil in place (OOIP) amount 2.581 MMBO. For Hana 4’s layer is deposited as sediment distributary mouth bar with relative deposition direction south west-north east. This layer contains oil with porosity values amount 0.10 and estimated contains reserved of oil in place (OOIP) amount 9.920 MMBO.
