Study area is located at Duri Field and as a part of Central Sumatra Basin, which consist of Tertiary sediment. Duri Field is one of oil field that is operated by PT Chevron Pacific Indonesia and included as developed area. In study area, sediment of Sihapas Group (Bangko Formation, Bekasap Formation, and Duri Formation) deposits at Early to Middle Miocene and contains abundant mikrofossil, therefore the lithologic samples of this area could be used for biostratigraphic and sequence stratigraphic analysis of some locality. This study used core, biostratigraphy, and log data of RST-1887, RST-3686, and RST-3697 wells. The sequence stratigraphic analysis has been carried by integrating two approaching methods: biostratigraphic and well log data analysis. Based biostratigraphic analysis, RST-1887, RST-3686, and RST-3697 wells has Early Miocene age interval, it is deposited in Lithoral to Middle Neritic environment and included into deltaic system. Stratigraphic analysis result shown the wells have five sequences cyclic, therefore there are only two of five sequence that have the complete boundary, this is happens because of the research area is not thick enough to include the other boundary. The cyclic bounded by SB (Sequence Boundary).
