Nowadays, oil and gas reserves have started thinning while needs of society of energy continue to grow. To satisfy these needs, development in exploration sector must be done like technology development and subsurface data acqusition. Sequence stratigraphy became one of study that could help for introducing and interpreting facies that could decrease exploration risk and fix corelation of units for exploration.
This Study use two main data, they are well data and seismic data. Eight well from this research useful for knowing body of sequence vertically with big scale. Meanwhile, two composite seismic from this research useful for knowing the spreading of sequence horizontally with smaller scale than well data.
In this study, writer determined six sequence that generated from interpretation based on well data and seismic. In these sequences, there are kind of System Tract that indicated condition when sediment particles was deposited, they are Lowstand System Tract, Highstand System Tract, and Transgressive System Tract. System Tract can be useful for interpretation potensial hydrocarbon propect that be stored in a resevoir with the help from Depth Structure Map as supported data.
