Abstract
The fore-arc basin has been become a target of reservoir searching for a long time based on previous expert studies, where the indications of Late-Miocene carbonate age that could act as a hydrocarbon reservoir was found. S-1 Well located in the Nias Basin, one of the fore-arc basin located in West of Sumatera. As the object of this study, it is hoped that the hydrocarbon reservoir in the fore-arc basin is expected to be discovered and to identify the characteristics of rocks that potential to become hydrocarbon reservoirs. Geochemical data becomes supporting data regarding the presence of gases that are identified as biogenic gases because of the content of methane as the main composition. Identification of the existence of reservoir zones and source rock is done by qualitative interpretation of log data from the S-1 well. Then, the petrophysical parameters are analyzed in the form of shale volume (Vsh), effective porosity, resistivity water (Rw), and water saturation (Sw) to determine the type of reservoir’s fluid. The results of the interpretation indicated that the presence of biogenic gas was detected in Late-Miocene with limestone lithology with Sw value 39.90 – 41.51 %.
