R Reservoir SF merupakan reservoir minyak saturated yang terletak padaWest Madura Offshore, memiliki jumlah sumur produksi sebanyak 2 sumurdengan tekanan awal sebesar 1769 psia dan tekanan bubble point pada 1792 psia.Tujuan utama pada tugas akhir ini adalah mengkaji ulang nilai perolehan dataawal dari metode volumetrik dan peramalan performa produksi reservoir SF padamasa yang akan datang dengan menggunakan software MBAL. Berdasarkanperhitungan dari metode volumetrik reservoir ini memiliki nilai Orignal Oil InPlace sebesar 6,74 MMSTB. Proses perhitungan dimulai dengan menentukanjenis drive mechanism SF reservoir. Menggunakan tiga metode yaitu metodekualitatif berdasarkan data produksi, metode Ganesh Thakur dengan memplotantara tekanan produksi dengan tekanan awal (P/Pi) terhadap kumulatif produksidengan isi awal minyak di tempat (Np/N), dan metode Drive Index yaitu denganmenghitung SDI (Solution Drive Index), GDI (Gas Drive Index), WDI (WaterDrive Index). Dari ketiga analisis ini menghasilkan tenaga dorong paling dominanadalah kombinasi antara Gas Cap drive dan Water drive. Pada penentuanoriginal oil in place dengan straight line method dibutuhkan nilai water influxyang dihitung menggunakan metode Fetkovich. Dengan batas keekonomisan pada30 STB/D sehingga dapat diketahi umur produktif sumur dapat diestimasi hingga27 Mei 2020. Analisa trend penuruan produksi dilakukan menggunakan metodeTrial Error and X2 – Chisquare Test dengan tipe decline adalah ExponentialDecline, dan harga Exponent Decline (b)= 0. Dengan nilai decline rate (Di)sebesar 0,049/bulan. Dan didapatkan nilai estimated ultimate recovery (EUR)sebesar 0,9817 MMSTB, recovery factor(RF) sebesar 16% dan remaining reserve(RR) sebesar 0,0249 MMSTB.

S SF Reservoir is a saturated oil reservoir located at West Madura Offshore,having 2 producing wells with an initial pressure of 1769 psia and bubble pointpressure at 1792 psia. The main objective of this thesis is to review the originaloil in place value from the volumetric method and forecast the performance of SFreservoir production in the future by using MBAL software. Based on calculationsfrom the volumetric method, the Orignal Oil In Place value is 6.74 MMSTB. Thecalculation process begins by determining the SF reservoir drive mechanism type.Using three methods, namely qualitative method based on production data,Ganesh Thakur method by plotting between production pressure with initialpressure (P / Pi) on cumulative production with initial oil content in place (Np /N), and the Drive Index method by calculating SDI ( Solution Drive Index), GDI(Gas Drive Index), WDI (Water Drive Index). From these three analyzes, the mostdominant thrust is the combination of Gas Cap drive and Water drive. Indetermining the original oil in place with the straight line method, the water influxvalue is calculated using the Fetkovich method. With an economic limit of 30 STB/ D so that the productive life of the well can be assessed until May 27, 2020.Analysis of the declining production trend is carried out using the Trial Error andX2 method - Chisquare Test with the decline type is Exponential Decline, andExponent Decline prices (b ) = 0. With a decline rate (Di) of 0.049 / month. Andthe estimated ultimate recovery (EUR) value is 0.9817 MMSTB, recovery factor(RF) is 16% and the remaining reserve (RR) is 0.0249 MMSTB.
