Abstract

Progressive Cavity Pump (PCP) has beenapplaid as artificial lift at X well that is ownedby PT Pertamina EP Asset 1 Field Jambi. Fromthe early calculation of current production gets17,16 bfpd that has not reached the target of48,57 bfpd. This indicates that PCP must beredesign. Before redisgn we used ProductivityIndex (PI) to make an Inflow PerformanceRelationship (IPR) curve that shows the oil isstill suitable production or not. We redisgn PCPusing R & M Energy Systems calculationmethods as the provider and found that theoptimal for revolution per minute (RPM), horsepower (HP), torque values and the drive headtype are 101,5 RPM, 2,7 HP, 15 ft-lbs and therehave to be a change in drive head type AA4. Toget results optimal production.

Abstract

The “E” well to be drilled is a development well in the “P” field located in the North Sumatra Basin. During the drilling operation in well “E” using HPWBM, HPWBM is used to overcome shale instability. This water-based mud is used because it is cheaper and more economical than using oil-based mud. However, this mud needs to be added with other chemicals because HPWBM has a weakness in controlling shale formation. The mud system design for the “E” well uses the offset well method, which uses data from nearby wells for comparison. Well “E” is divided into two intervals. Hole interval 12 1/4" with 9 5/8" casing from 24 m to 290 m depth using HPWBM. Then proceed with 8 1/2" hole intervals with 7" casing from 290 m to 530 m depth using the same mud. The problem this well will face is pressure at a depth of 500 m, thus increasing the mud density from 12 ppg to 14 ppg to prevent kick.

Abstract

Energi panas bumi telah menjadi salah satu energi alternatif penting di seluruh dunia selama beberapa tahun terakhir. Well Completion merupakan serangkain tes untuk mendapatkan data karakteristik sumur. Analisis pada penelitian ini dilakukan pada sumur X lapangan Y secara kualitatif dan kuantitatif. Berdasarkan quicklook pada grafik PTS, liquid level injection 1200 GPM pada kedalaman 628 m melalui data pressure. Korelasi temperature dan spinner diperoleh feedzone pertama di 1074-1095 m, feedzone kedua di 1170-1195 m, feedzone ketiga di 1232-1234 m dan feedzone keempat di 2604-2611 m. Perhitungan nilai slope dapat ditentukan dengan melalui spinner vs cable speed di plot terhadap kedalaman. Nilai slope yang diperoleh berdasarkan adalah 7.2. Laju alir fluida yang diperoleh rata-rata pada feedzone pertama sebesar -1.27 m/s, feedzone kedua sebesar -1.42 m/s, feedzone ketiga sebesar -1.35 m/s dan feedzone keempat sebesar -2.27 m/s. Nilai laju alir massa pada feedzone pertama sebesar 11.06 kg/s dengan kontribusi 42%, feedzone kedua sebesar 8.08 kg/s dengan kontribusi 30%, feedzone ketiga sebesar 1.38 kg/s dengan kontribusi 6%, dan feedzone keempat sebesar 5.78 kg/s dengan kontribusi 22%. Berdasarkan spesific steam comsumsion untuk menghasilkan 1 Mwe dibutuhkan 2 kg/s steam diperoleh estimasi produksi sekitar 13.15 MWe. Injectivity Index (II) rata-rata sebesar 532.81 ton/hr/bara. Pressure Fall Test dilakukan untuk mengetahui penurunan pressure sehingga diperoleh nilai transimivitas, permeabilitas dan skin menggunakan Horner Chart. Nilai slope sebesar 0.352 ksc/cycle, tekanan awal sebesar 88.09 ksc dan tekanan 1 jam sebesar 88.23 ksc, permeabilitas diperoleh sebesar 7.38 mD dan skin factor sebesar -13.168 yang dapat diartikan adanya perbaikan pada reservoir.
