There are 5 facies association which deposited on the different zone. The skeletal facies of debris - planktonic foraminifera wackestone to packstone are deposited in the reef front, the coral packstone facies association as well as the coral - algae packstone and algae - large foraminifera bindstone in the flat reef zone and the reef flat - reef, coral - large foram mudstone to wackestone and coral - skeletal debris mudstone to wackestone associations in the lagoon zone. From several analysis, we can conclude that reservoir quality is not controlled by facies differences but from the analysis of diagenesis, porosity value and time deposition. In the study area it is recommended that reservoirs are best located at intervals reef flat and reef flat – reef crest with keep-up carbonate growth pattern, and the result of diagenesis is dominated by vuggy porosity, in addition to fracture porosity, channel porosity, and hydrocarbon filling on porosity. Therefore, the recommended intervals are expected to still have relatively good remaining oil content and become a reference for continuing exploration in other wells.
