Heavy Oil Potentials in Central Sumatra Basin, Indonesia Using Remote Sensing, Gravity, and Petrophysics Data: From Literature Review to Interpretations and Analyses

Central Sumatra basin is located on Island, Indonesia, and considered an oil prolific that produces heavy oil. The believed to have unexplored potential. Therefore, this study aims map the potential distribution in using surface subsurface lineaments analyses interpreted from satellite imagery gravity data, assisted by well log/petrophysics analysis. A thorough analysis was conducted based surface/subsurface structures’ control source rock location settings all traps. anomaly data interpretation identified low areas NW – SE, N S directions. of imageries showed very similar lineament patterns with same general direction. It observed there continuity between features, which provide contact reservoirs water sources, thereby facilitating generation. Overlapping supported petroleum system understanding verification wells confirmed 7 trap within sedimentary basin.
