D aerah penelitian terletak di Sub-Cekungan Palembang Selatan, Cekungan Sumatera Selatan. Eksplorasi hidrokarbon di daerah ini masih berlangsung sampai sekarang, sehingga perlu dilakukan banyak studi baik dengan konsep eksplorasi maupun pengembangan. Tatanan stratigrafi daerah penelitian adalah: Formasi Air Benakat, Formasi Gumai, Formasi Baturaja, Formasi Talang Akar, Formasi Lahat, dan Basement. Penelitian ini akan memfokuskan kepada estimasi cadangan gas di tempatFormasi Baturaja di daerah penelitian yang memiliki jenis litologi batugamping. Datayang digunakan dalam penelitian ini antara lain: data log sumur AGN-03, AGN-04, AGN-05, AGN-06, AGN-07, Seismik 3D dan data checkshot sumur AGN-06. Metodeyang digunakan dalam penelitian ini dimulai dengan penentuan interval batas atas dan batas bawah Formasi Baturaja, well seismic tie, interpretasi seismic 3D, sertaperhitungan petrofisik. Formasi Baturaja daerah penelitian berupa batugampingdengan jenis floatstone dan floatstone dan diperkirakan merupakan bagian dariplatform batugamping yang memiliki slope rendah. Area target prospek berupaperangkap struktur dengan jenis four-way dip anticline. Berdasarkan hasil perhitunganpetrofisik untuk properti reservoir daerah penelitian memiliki porositas sebesar 17%dan saturasi air 62%. Volume gas di tempat sebesar 86.5747 bcf dan cadangan (reserves) sebesar 64.0653 bcf.
R esearch area is located at South Palembang Sub Basin, South Sumatra Basin.Hydrocarbon exploration occur until present day, so it’s still need much study withexploration and/or development concept to estimate hydrocarbon resources. RegionalStratigraphy in this area are: Air Benakat Fm., Gumai Fm., Baturaja Fm., Talang AkarFm., Lahat Fm., and Basement. This study is focus on original gas in place estimationof Baturaja Formation. This study was based on data which consist of well log data ofAGN-03, AGN-04, AGN-05, AGN-06, AGN-07, seismic 3D, and check shot data ofAGN-06 well. Methodes which were used in this study was began with determine thetop and bottom of Baturaja Formation, well seismic tie, seismic 3D interpretation andpetrophysical analysis. Baturaja Formation in research area consist of reefal limestoneand the type are rudstone & floatstone and estimated to be a part of limestone platform on lower slope. Target area prospect associated with structural traps, the type is fourway dip anticline. Based on petrophysical analysis for reservoir property, research area has 17% porosity and 52% water saturation. Original gas in place volume is 86.5747 bcf and reserves is 64.0653 bcf.
