Abstract

D aerah penelitian lapangan â€AALâ€ terletak di sub-cekungan Jambi, CekunganSumatera Selatan. Target utama penelitian adalah Formasi Airbenakat denganlitologi penyusunnya adalah batupasir dan batulempung. Penelitian ini membahaskarakterisasi reservoir lapisan batupasir Formasi Airbenakat, dimulai daripengkajian data, dan analisa data sumur. Data sumur yaitu berupa data log, datatersebut dianalisis untuk mengetahui litologi, sekuen stratigrafi, fasies danlingkungan pengendapan serta parameter petrofisika. Hasil dari analisis tersebutuntuk mengetahui karakterisasi reservoar lapisan batupasir. Di daerah penelitiandiinterpretasikan terdapat tiga zona sekuen yaitu SB1-MFS1-SB2, SB2-MFS2-SB3, SB3-MFS3-SB4. Fasies yang berkembang pada lapangan yaitu: DistributaryMouth Bar, Distributary Channel. Lingkungan pengendapan terdiri atas: delta plaindan delta front. Terdapat dua zona target reservoir penelitian, zona A terdapatdiantara SB2-MFS, zona B terdapat diantara MFS3-SB4. Lapisan reservoir zona Adengan nilai rata-rata porositas 10-15% (sedang-cukup), permeabilitas 5,11 Md(cukup), saturasi air 0,77. Lapisan reservoir B dengan nilai rata-rata porositas 15-20% (cukup-baik), permeabilitas 10,51 mD (baik), saturasi air 0,76. Lapisanreservoir B mempunyai nilai lebih baik dan ekonimis dibandingkan reservoir A.

T he area for this research is "AAL" field located in Jambi Sub Basin, SouthSumatera Basin. The main target of the research is Airbenakat Formation as consistof sandstone and shale. This study discusses the reservoir characterization of theAirbenakat formation of sandstone layer, starting from the data assessment, andwell data analysis. The well data is using log data, and this log data is analyzed tofind lithology, stratigraphic sequence, facies, depositional environment andpetrophysical parameter. The result of this analysis is to know the characterizationreservoir of sandstone layer. In the study area there were three sequence zones:SB1-MFS1-SB2, SB2-MFS2-SB3, SB3-MFS3-SB4. Facies that develop in the fieldare: Distributary Mouth Bar, Distributary Channel. And for the depositionalenvironment consists of: delta plain and delta front. There are two researchreservoir target zones, zone A is between SB2-MFS, zone B is between MFS3-SB4.Reservoir layer of zone A with an average porosity value of 10-15% (mediumenough),permeability of 5.11 Md (enough), saturation water 0.77. Reservoir layerB with an average porosity value of 15-20% (good enough), permeability 10.51mD(good), saturation water 0.76. So reservoir B zone has better value and economicalthan reservoir A zone
