Abstract

The purpose of this study is to identify type of play for Paleogene rift sediments in Ngimbang Sub Basin to open a new opportunities to search the future potential of hydrocarbon reserves. Each phase in rift evolution will be subdivided by Prosser (1993) tectonostratigraphy concept. Seismic stratigraphy interpretation is used to distinguish each tectonic phases: rift initiation (S2), rift climax (S3), immediate post rift (S4), and late post rift (S5). Depositional models in Ngimbang Sub Basin will be generated from isochrones maps for S1, S2-S1, S3-S2, S4-S3, and S5-S4 tectonic phase with its own unique seismic expression to recognize its facies. Most of the working process will be focused on the distribution and understanding type of reservoir rock from Ngimbang Formation within the area while other geological factors will be utilize from combination of data interpretation and other publications to conclude play type for Paleogene rift sediments in East Java Basin. In conclusion, there are at least four type of play in this area: facies change play, alluvial fan play, basin floor fan play, and channel fill play. It is expected that these play will open a new exploration opportunity in Ngimbang Sub Basin.
