Currently, the amount of available conventional gas and oil content are more limited while the amount of reserves has been decreased. Therefore we need an exploration of new resources, one solution is to expand the exploration of hydrocarbons that include unconventional resources such as shale gas. Shale gas is natural gas from shale rock. Called non-conventional hydrocarbons because the presence of the source in nature and some of the physical properties that are different from conventional hydrocarbons. <br /> <br /> <br /> <br /> This study describes the initial exploration about the potential of shale gas on a block in south Sumatra basin which has shale reservoir in Gumai Formation. Statigraphically, this reservoir has thin beds and have variation with sandstones and limestones. In this study integrates geochemical data, analysis of petrophysic, and seismic inversion technique to characterize shale gas potential zones. Early stages of exploration in the determination of sweetspot is using Passey Method to generate pseudo TOC. Second, petrophysical analysis to obtain physical parameters that are sensitive to the target formation. Third is by applying extended elastic impedance seismic inversion to determine the distribution of shale rock that contain gas potential based on the value of TOC and physical parameters that are sensitive to the target formation.
