Abstract

The Kotagaro area is one of the hydrocarbon field in the Central Sumatra basin one of the old giant hydrocarbon basins in Indonesia. Only Post-rift deposit are well explored in the Kotagaro are,while Synrift deposit of Pematang Group still not being explored as a reservoir, because they are not a focus in the development study. Research on synrift interval is expected to be new knowledge, especially in the Kotagaro area. This study aims to explore (new insights) regarding synrift interval by analyzing seismic facies and interpreting the depositional environments of the study area. This study used 2D and 3D seismic data and data from a well located outside the study area. Well data is used for well-seismic tie. The methods used in this study included well-seismic tie, 2D and 3D seismic interpretations the synrift intervals, generation of time structure maps and isochrones maps seismic facies analysis, and interpretation of depositional environments. Based on this analysis, the research area has four seismic facies, Chaotic Wedge (AM), Divergent Wedge (DM), Hummocky Wedge (HM), and Parallel Wedge (PM). The four seismic facies showed that the study area was deposited in the fluvial zone, alluvial fan zone, deep lacustrine zone, shallow lacustrine zone, and lacustrine shoreline zone.

Abstract

Kutai Basin has proven to be a productive basin and has great potential, this fact indicating the existing petroleum system has been running well. Therefore, more specific investigations need to be carried out, especially for development of non-conventional hydrocarbon reserves, and find out in detail the characteristics of rocks that have potential to be carriers of potential shale gas in the Kutai Basin. The used data in this study included 5 (five) drilling wells, Ramin-1, Rasamala-1, Buat-1, Busang-1, and Murung-1 which contained wireline log data, mud logs, biostratigraphic analysis, geochemical analysis, and 81 line 2-D seismik trajectories. Further interpretation using geochemical data and modelling with Passey Method. In geomechanical data analysis, modeling used wireline logs, produce Young modulus values, Poisson ratios, and rock brittleness. Petrophysical analysis was used to be a parameter of rock quality. These data are depicted vertically and horizontally with seismic data benchmark, resulting in facies distribution and rock quality parameters as shale gas reservoirs. The research showed that Pulobalang Formation in the study area, deposited in the deltaic to slope environment, with type III kerogen, TOC content level poor until excellent with 0.12 - 7% value and brittleness value 0.05-0.971. The calculation was conducted based standard criteria as shale gas reservoir. Total potential of shale gas resources in the Pulobalang Formation reaches 2.78 TCF.
