Pengaruh Variasi Parameter Operasi Sucker Rod Pump Terhadap Peningkatan Produksi Di Sumur Ah-052

Abstrak

Sumur AH-052 menggunakan pompa Sucker Rod Pump (SRP) mulai mengalami penurunan produktivitas seiring berjalannya waktu. Kinerja sumur minyak AH-052 di Sumatera Selatan yang menggunakan Sucker Rod Pump (SRP) sebagai sistem pengangkatan buatan. Sumur ini memiliki kedalaman 289,87 meter dengan interval perforasi 236,52–238,05 meter. Sebelum optimasi, sumur ini menunjukkan laju produksi 264 BFPD dengan water cut 97% dan efisiensi pompa hanya 72,28 %. Melalui variasi parameter sistem pompa SRP, spesifikasi peralatan yang tersedia yaitu rod 1 1/4 inci dan 1 1/8 inci, nomor rod 109, plunger 2 inci, panjang langkah (SL) 140 inci, dan kecepatan pompa (n) 5 spm. Parameter yang digunakan berhasil meningkatkan efisiensi pompa secara signifikan menjadi 91,12 % dan laju produksi naik menjadi 381,2 BFPD. Analisis kelayakan ekonomi berdasarkan model kontrak bagi hasil Production Sharing Model Contract Cost Recovery menunjukkan hasil yang sangat positif. Proyek ini menghasilkan Net Present Value (NPV) sebesar MU$202,08, Internal Rate of Return (IRR) 1153 %, Pay Out Time (POT) 0,086 tahun, dan Profitability Index (PI) 22,56. Berdasarkan indikator-indikator tersebut, proyek optimasi ini dianggap sangat layak secara finansial dan memberikan keuntungan yang substansial.

AH-052 well, which uses a Sucker Rod Pump (SRP), began to experience a decline in productivity over time. The performance of the AH-052 oil well in South Sumatra, which uses a Sucker Rod Pump (SRP) as an artificial lift system. This well has a depth of 289.87 meters with a perforation interval of 236.52–238.05 meters. Before optimization, this well showed a production rate of 264 BFPD with a water cut of 97% and a pump efficiency of only 72.28%. Through variations in the SRP pump system parameters, the available equipment specifications were 1 1/4 inch and 1 1/8 inch rods, rod number 109, plunger 2 inch, stroke length (SL) of 140 inch, and pump speed (n) of 5 spm. The parameters used successfully increased pump efficiency significantly to 91.12% and production rate to 381.2 BFPD. Economic feasibility analysis based on the Production Sharing Model Contract Cost Recovery contract model showed very positive results. This project generated a Net Present Value (NPV) of MU$202.08, an Internal Rate of Return (IRR) of 1153%, a Pay Out Time (POT) of 0.086 years, and a Profitability Index (PI) of 22.56. Based on these indicators, this optimization project is considered highly financially viable and provides substantial benefits.
