Abstract
Nowadays, research paradigm which occurs in the objectivity of academics and industrial landscape lead to a gap of judgment upon geological evolution, especially on outcrops analog on hydrocarbon exploration study and both perspectives can be combined in this study. The study is located on Walat Fm., Sukabumi. West Java. The data were collected from field mapping, measured section, and direct sampling. Processing data is done by using Darcy’s method and thin section analysis to define porosity and permeability and also qualitative interpretation to analyze the geometry of the reservoir itself. The stratigraphic column and the measured section of the area shows that Walat Fm. is considered as a good reservoir as the formation is laterally distributed around 5-6 km and vertically thickens to 150 ft. Also, the porosity and permeability of the sandstone qualified as the oil reservoir rocks. The geological section provides the information of petroleum elements such as traps, migration, and seal. Source rock geochemically tested and classified as moderate – good source rock. As a result of all the studies, Walat Fm. is concluded as a potentially good reservoir analog to be further analyzed to determine the hydrocarbon contain and prospect.
