Abstract

The purpose of this study is to estimate the potential of shale gas Talang Akar Formation based on the surface and subsurface data analysis. The MB Area is lies in the Jambi Sub Basin which is part of the South Sumatra Basin. The area is approximately 758 km2 • Administratively, located in Batanghari Regency, Jambi Province. The Jambi Sub-Basin was underlain by Pre-Tertiary basement rocks. The Tertiary sedimentation commenced with the syn-rift sediments of the Eocene Lahat then Talang Akar formation unconformably o~·erlies the Lahat Formation. That formation was deposited during Oligo-Miocene was succeeded by the pre-dominantly sag phase. Furthermore, Middle-Late Miocene Gumai Formation was deposited overlying Talang Ak.:!r Formation. Overlying Gumai Formation was deposited Air Banakat and Muaraenim Formations. The structural that develops are NE-SW trending normal fault, and NW-SE trending reserve fault & fold fault and folds with NW-SE direction. Geochemical analysis results indicate that the shale Talang Akar has potential cs a source rock that can produce gas when it has reached a level of maturity. Brittleness Index is obtained from X-ray diffraction analysis shows the brittle properties with 46% quartz content (brittle) . The physical reservoir properties used for estimating the shale gas resources at Talang Akar Formation are : porosity (0. 04); average water saturation (0.35) ; bulk volume is 6, 38xl 010m3 , TOC 1, 6%; Vitrinite Reflectance I Ro (1, 35%) and physical gas characteristic: free gas cotltent = 7 8, 62 5 scPton and adsorbed gas = 49 scjlton.
