Sumur “NA-25” di Lapangan “SK” menggunakan ESP yang memiliki peran krusial
dalam menjaga produktivitas produksi minyak dari sumur yang sudah mengalami
penurunan tekanan sehingga analisis keekonomian dapat dilakukan untuk
mengetahui strategi ekonomi yang efektif bagi perusahaan dalam memilih antara
menyewa atau membeli (purchase) electrical submersible pump (ESP) untuk
meningkatkan produktivitas produksi minyak. PSC Cost Recovery dipilih untuk
diaplikasikan karena PSC Cost Recovery dapat mengembalikan biaya operasi yang
dikeluarkan oleh KKKS dengan persetujuan SKK Migas, pembagian hasil
dilakukan terhadap profit margin, dan presentase bagi hasil dalam satu wilayah
kerja relatif sama dan berubah apabila berasal dari lapisan (reservoir) yang lebih
tua dan dilakukannya EOR pada lapangan tersebut.
Pada penelitian Lapangan “SK”, dilakukan penentuan sewa atau beli pompa ESP
dengan menggunakan skema PSC Cost Recovery. Pengerjaan dimulai dengan
menetukan prediksi laju produksi minyak Sumur NA-25 menggunakan Analisis
Decline Curve dengan Metode Trial Error dan X2 Chi-Square Test sehingga
menghasilkan data annual production, menghitung perkiraan biaya investasi dan
operasi, depresiasi, cash flow, dan analisis sensitivitas. Penjumlahan contractor
take, goverment take, dan cost recovery digunakan untuk validasi keekonomian.
Hasil analisis perhitungan decline curve didapatkan tipe exponential curve dengan
nilai b sama dengan 0 dan decline rate sebesar 0,0995/month. Hasil perhitungan
dan analisis keekonomian Sumur “NA-25” menghasilkan nilai NPV skenario sewa
pompa ESP sebesar 14,26 MMUSD dan skenario beli pompa ESP sebesar 14,21
MMUSD. Selain NPV, skenario beli pompa ESP menghasilkan nilai PIR senilai
8,27 dan DPIR senilai 7,29. Skenario sewa pompa ESP lebih layak untuk
dikembangkan karena nilai NPV sewa pompa ESP lebih besar daripada skenario
beli pompa ESP. Hasil sensivitas yang dilakukan menunjukkan bahwa nilai oil
price dan OPEX sangat sensitif terhadap perhitungan cash flow.
Kata Kunci: Chi-Square, Cost Recovery, Decline Curve, ESP, PSC.
ABSTRACT
ECONOMIC ANALYSIS OF DETERMINING TO RENT OR
PURCHASE ESP “NA-25” WELL "SK" FIELD USING PSC
COST RECOVERY SCHEME

The “NA-25” well in “SK” Field uses an ESP that had a crucial role in maintaining
the productivity of oil production from wells that have experienced a decrease in
pressure, so that an economic analysis can be carried out to determine an effective
economic strategy for companies in choosing between renting or purchasing an
electrical submersible pump (ESP) to increase oil production productivity. PSC
Cost Recovery was chosen to be applied because that contract can return the
operating costs incurred by the KKKS with the approval of SKK Migas, the
distribution of results is carried out against the profit margin, and the percentage
of profit sharing in one work area is relatively the same and changes if it comes
from an older layer (reservoir) and EOR is carried out in the field.
ESP pump rental or purchase was determined using the PSC Cost Recovery scheme
in “SK” Field. The calculation process began by determining the predicted oil
production rate for the NA-25 Well using Decline Curve Analysis with Trial Error
and X2 Chi-Square Test Method to calculate investment and operating costs
estimation, depreciation, cash flow and sensitivity analysis. Sum of contractor take,
goverment take, and cost recovery is used for economic validation.
The results of the decline curve analysis calculation obtained an exponential curve
with b value of 0 and the decline rate of 0.0995/month. The results of economic
calculations and analysis for the "NA-25" Well produced NPV value for renting an
ESP pump on a well was 14.26 MMUSD and for buying an ESP pump scenario was
14.21 MMUSD. Besides NPV, buying ESP scenario produced 8.27 for PIR and 7.29
for DPIR. It can be concluded that the rental scenario’s more feasible than buying
an ESP pump because NPV value of renting ESP pump scenario is greater than
buying ESP pump scenario. The sensitivity results show that oil price and OPEX
values are very sensitive to cash flow calculations.
