Reservoir Characterization Sandstone Reservoir Based on Wireline Log

The hydrocarbon exploration in the sandstone reservoir is still the main interest in Indonesia, in addition to the carbonate reservoir, as the main hydrocarbon reservoirs. To understand the sandstone reservoir characters, this research was conducted to understand the sandstone reservoir behaviour using petrophysics calculation. The characterization of reservoir was conducted by integrating the subsurface data, including ditch cuttings and wireline log. The petrophysics character is used to interpret the geological conditions in the subsurface. The petrophysical analyses used in this research was gained from one well, by calculating the volume of shale (Vshale), porosity, permeabillity and water saturation. The petrophysics calculation of the reservoir indicate the following parameters: Vshale of 0.51-0.091%, Porosity PHIT of 0.17-0.2%, PHIE of 0.12-0.19%, Permeability of 10.1-249.8 mD, saturation water of 0.24-0.221%
