R Reservoir Tosche merupakan reservoir minyak yang relatif baru dimana reservoir ini memiliki satu sumur produksi RED-2 yang sudah berproduksi sejak 31 Oktober 2013. Estimasi nilai original oil in place (OOIP) merupakan hal yang sangat penting dalam aspek operasional. Oleh karena itu, tujuan utama pada penelitian adalah melakukan perkiraan yang akurat terhadap volume original oil in place reservoir Tosche dan meramalkan performa produksi di masa yang akan datang. Berdasarkan analisa data sejarah produksi dengan metode kualitatif, drive index dan Ganesh Thakur, diperoleh hasil jenis tenaga dorong yang sama yaitu reservoir Tosche ini memiliki tenaga dorong dominan solution gas drive. Berdasarkan perhitungan original oil in place (OOIP) digunakan empat metode yaitu volumetrik, material balance, straight line material balance Havlena-Odeh dan software IPM MBAL diperoleh nilai original oil in place (OOIP) berturut - turut sebesar 2907,005 MSTB, 2923 MSTB, 2875 MSTB dan 2848,9 MSTB, sehingga hasil perhitungan ini valid karena memiliki persen perbedaan yang kecil berturut - turut sebesar 0,5%, 1,1% dan 2%, terhadap hasil perhitungan metode volumetrik. Untuk mengetahui performa produksi dan estimate ultimate recovery (EUR) digunakan metode decline curve analysis pada tren yang mewakili model penurunan produksi pada reservoir Tosche yaitu pada tanggal 31 Desember 2016 hingga 31 Mei 2017. Ekstrapolasi data dari trend penurunan produksi menggunakan dua metode yakni metode Trial Error dan X2 - Chisquare Test dan metode software OFM, dimana diperoleh tipe kurva decline yang sama yaitu Exponential Decline dengan harga Exponent Decline (b) = 0 untuk kedua metode. Untuk parameter lain, nilai yang diperoleh juga hampir sama dengan harga laju decline (Di) berturut – turut sebesar 0,0202/bulan dan 0,0199/bulan, EUR berturut – turut sebesar 341,419 MSTB dan 342,398 MSTB, Recovery Factor berturut – turut sebesar 11,98% dan 12,02%, yang dapat berproduksi berturut - turut hingga bulan Januari 2026 dan Februari 2026, pada batas economic limit yang sama yaitu 10 STB/day.

T Tosche Reservoir is a relatively new oil reservoir where the reservoir has one RED-2 production well that has been in production since 31st of October 2013. The estimated value of the original oil in place (OOIP) is very important in the operational aspect. Therefore, the main objective of this study is to make an accurate estimate of original oil in place on Tosche reservoir and forecasting future production performance. Based on the analysis of production history data with qualitative, drive index and Ganesh Thakur methods, obtains the same type of drive mechanism that is the Tosche reservoir has the dominant thrust of solution gas drive. Based on the original oil in place (OOIP) calculations using four methods, namely volumetric, material balance, straight line material balance Havlena-Odeh and IPM MBAL software, the original oil in place (OOIP) value is 2907,005 MSTB, 2923 MSTB, 2875 MSTB and 2848,9 MSTB respectively. The results of this calculation are valid because they have a small percentage difference of 0.5%, 1.1% and 2% respectively against the result of the volumetric method calculation. In order to determine the production performance and ultimate recovery (EUR) estimation, the decline curve analysis method is used in the trend that represents the production reduction model in the Tosche reservoir, which is on December 31, 2016 until May 31, 2017. Extrapolation of data from the decreasing trend of production uses two methods, Trial Error and X2 - Chisquare Test and OFM software method, which obtained the same decline curve type which is Exponential Decline with Exponent Decline (b) = 0 for both methods. For other parameters, the value obtained is also almost the same with the decline rate (Di) of 0,0202/month and 0,0199/month respectively, EUR of 341.419 MSTB and 342.398 MSTB respectively, recovery factor 11,98% and 12,02%, respectively, which can produce until January 2026 and February 2026 respectively, with same economic limit of 10 STB / day.
