D Daerah penelitian berada di Formasi Baturaja Cekungan Sumatra Selatan. Cekungan Sumatra Selatan dibatasi oleh Paparan Sunda di sebelah timurlaut, Tinggian Lampung di sebelah tenggara, Pegunungan Bukit Barisan di sebelah baratdaya, serta Pegunungan Duabelas dan Pegunngan Tiga Puluh di sebelah baratlaut. Penelitian yang dilakukan meliputi analisis kualitatif dan kuantitatif . Analisis kualitatif meliputi data log maupun data sekunder. Sedangkan analisis kuantitatif menggunakan perhitungan petrofisika. Berdasarkan analisis sayatan tipis petrofisika fasies pada sumur SYP-1, SYP-2, SYP-3 dan SYP-6 diperoleh lima jenis fasies batugamping yaitu wackstone, packstone, wackstone to packestone, Rudstone dan Dolomite Floastone. dengan kandungan mineral yang didominasi oleh kalsit sparit dan mikrit yang terendapkan pada lingkungan laut dangkal. Porositas yang berkembang di daerah penelitian adalah porositas sekunder hasil pelarutan dan rekahan. Porositas rata-rata hasil dari interpretasi peta isoporositas didapatkan porositas yang tersebar di lapangan SYP rata-rata sebesar 40% - 48%. Dari hasil Perhitungan cadangan hidrokarbon area penelitian memiliki cadangan hidrokarbon yang terakumulasi sebesar 14.225 MMCF.

T The research area is in the South Sumatra Basin Baturaja Formation. The South Sumatra Basin is bordered by the Sunda Shelf in the northeast, Lampung Tinggian in the southeast, Bukit Barisan Mountains in the southwest, and the Twelve Mountains and Thirty Mountains in the northwest. The research conducted included qualitative and quantitative analysis. Qualitative analysis includes log data and secondary data. While quantitative analysis uses petrophysical calculations. Based on the analysis of thin facies of petrophysical facies on SYP-1, SYP-2, SYP-3 and SYP-6 wells, five types of limestone facies were obtained, namely wackstone, packstone, wackstone to packestone, Rudstone and Dolomite Floastone. with mineral content which is dominated by sparite and micrite calcite which are deposited in shallow marine environments. The porosity that develops in the research area is secondary porosity resulting from dissolution and fracture. The average porosity of the results of the interpretation of the isoporosity map found porosity scattered in the SYP field by an average of 40% - 48%. From the results of the calculation of hydrocarbon reserves the research area has hydrocarbon reserves which accumulate at 14,225 MMCF.
