D Dari analisis log, akan diperoleh beberapa parameter seperti volume shale(Vsh), porositas efektif (Øe), resistivitas air formasi (Rw), saturasi air (Sw) dannet pay. Pada lapangan “S†sumur R-1A, R-3 dan R-4 didapat nilai Vsh denganmenggunakan gamma ray dari tiap zona adalah X-1 = 13,6 - 40,5%, X-2 = 11,2 -31,4%, X-3 =6,6 - 18,5%, X-4 =10,1% , X-5 =18,9 - 25,9% , X-6 =17,7% , X-7=15,8 - 62,9% , X-8 = 13,8 - 20,4%, X-9 = 9,9%, X-10 = 17,4 - 34,9%, X-11 =6,9%. Kemudian dengan menggunakan metode porositas neutron-density, makadidapat nilai Øe pada lapangan “S†sumur R-1A, R-3 dan R-4 adalah untuk zonaX-1 = 14,4 - 18,6%, X-2 = 18,9 - 21,4%, X-3 = 13,9 - 18,8%, X-4 = 12,8%, X-5 =10,2 – 15,1%, X-6 = 10,9%, X-7 = 5,0 - 14,6%, X-8 = 10,3 - 13,5%, X-9 = 7,6%,X-10 = 7,8 – 13,9%, X-11 = 13,7%. Nilai Rw pada sumur R-1A dan R-3 denganmenggunakan picket plot adalah 0,49 Ωm dan 0,35 Ωm. Sedangkan untuk sumurR-4, nilai Rw didapat dari analisis air formasi sebesar 0,36 Ωm. Dalammenentukan saturasi air pada lapangan “S†ini menggunakan metode FormulaIndonesia, Simandoux, Waxman & Smits dan Dual Water Model. Dari keempatmetode tersebut, dipilih metode Simandoux yang dinilai lebih mewakili nilaisaturasi air DST pada lapangan “Sâ€. Nilai saturasi air dengan metode Simandouxpada sumur R-1A, R-3 dan R-4 adalah untuk zona X-1 = 62,1 - 96,2%, X-2 = 55,1- 74,6%, X-3 = 94,6 - 100%, X-4 = 34,4%, X-5 = 83,1 - 89,5%, X-6 = 38,3% , X-7 = 37,4 - 63,7%, X-8 = 55,6 - 100%, X-9 = 35,5%, X-10 = 24,5 - 67,9% dan X-11 = 33,5%.
F From log analysis, will be obtained some parameters such as shale volume(Vsh), effective porosity (Øe), formation water resistivity (Rw), water saturation(Sw) and net pay. In “S†field, the value of shale volume in R-1A, R-3 and R-4well using gamma ray for every zones are X-1 = 13,6 - 40,5%, X-2 = 11,2 -31,4%, X-3 =6,6 - 18,5%, X-4 =10,1% , X-5 =18,9 - 25,9% , X-6 =17,7% , X-7=15,8 - 62,9% , X-8 = 13,8 - 20,4%, X-9 = 9,9%, X-10 = 17,4 - 34,9%, X-11 =6,9%. With using neutron-density porosity method, the value of Øe for R-1A, R-3and R-4 in every zones are X-1 = 14,4 - 18,6%, X-2 = 18,9 - 21,4%, X-3 = 13,9 -18,8%, X-4 = 12,8%, X-5 = 10,2 – 15,1%, X-6 = 10,9%, X-7 = 5,0 - 14,6%, X-8= 10,3 - 13,5%, X-9 = 7,6%, X-10 = 7,8 – 13,9%, X-11 = 13,7%. The value of Rwin R-1A and R-3 well using picket plot are 0,49 Ωm and 0,35 Ωm. From theformation water analysis, the value of Rw in R-4 well is 0, 36 Ωm. In determiningwater saturation in “S†field using Formula Indonesia methode, Simandoux,Waxman & Smits and Dual Water Model. From all the methods above,Simandoux is chosen because the water saturation represents the value of watersaturation in “S†field. Water saturation using Simandoux in R-1A, R-3 and R-4well for every zones are zona X-1 = 62,1 - 96,2%, X-2 = 55,1 - 74,6%, X-3 = 94,6- 100%, X-4 = 34,4%, X-5 = 83,1 - 89,5%, X-6 = 38,3% , X-7 = 37,4 - 63,7%, X-8 = 55,6 - 100%, X-9 = 35,5%, X-10 = 24,5 - 67,9% dan X-11 = 33,5%.
