This field is located at Bintuni, West Papua. The objectives of this work are to perform detailed <br>depositional facies analysis and to interpret the diagenesis process using rock typing for assessing the <br>potential of the carbonate reservoir. Kais Formation limestone was classified into three members; Upper Kais, <br>Middle Kais, and Lower Kais, which are associated with five different facies (i.e., shelf, front reef, inter reef, <br>back reef, and core reef facies). The associated facies were interpreted as reefal platform carbonate. The <br>reservoir quality was reviewed by facies distribution, petrography, and biostratigraphy. Our analysis shows <br>that the Upper and Middle Kais were controlled by compaction and dominated by fractured porosity, while in <br>contrast, the Lower Kais was controlled by dolomitization and dissolution diagenesis. </p> ER -
