Lapangan “REN” telah berproduksi sejak Agustus 1997 hingga Desember 2022.
Lapangan ini memiliki 12 sumur, dengan 7 sumur yang telah shut-in, 4 sumur
produksi, dan 1 sumur injeksi gas. OOIP pada lapisan ini sebesar 26,83 MMSTB
dengan kumulatif produksi pada Desember 2022 sebesar 6,26 MMSTB dan
recovery factor sebesar 23,30%. Studi ini dilakukan bertujuan untuk mengetahui
skenario pengembangan lapangan yang paling optimum dengan metode konversi
sumur injeksi gas immiscible.
Tahapan pengerjaan diawali dengan persiapan data berupa model statis reservoir,
data karakteristik reservoir, dan data produksi. Selanjutnya dilakukan pengolahan
data routine core analysis (RCAL), special core analysis (SCAL), dan data PVT
fluida reservoir. Setelah itu dilakukan proses inisialisasi, history matching, dan PI
matching untuk memvalidasi model simulasi. Selanjutnya dilakukan skenario
pengembangan lapangan dengan menentukan pola injeksi, sensitivitas laju injeksi,
dan tekanan injeksi yang paling optimal pada injeksi immiscible gas.
Skenario terbaik yang terpilih adalah skenario 3D, yaitu sensitivitas laju injeksi gas
dengan dasar skenario 1B yang menggunakan pola five spot, namun laju injeksi gas
yang digunakan sebesar 4.000 MSCF/D berdasarkan asumsi bahwa gas melimpah
di Lapangan ”REN”, Kumulatif produksi minyak yang dihasilkan sebesar 7,50
MMSTB, recovery factor sebesar 27,97%, peningkatan recovery factor sebesar
3,81%, dan watercut sebesar 90,47%
Kata kunci: Konversi Sumur Injeksi, Injeksi Immiscible Gas, Recovery Factor.

ABSTRACT
FIELD DEVELOPMENT SCENARIO OF “REN” FIELD “NAL”
LAYER BY CONVERTING SELECTED WELLS INTO CO²
IMMISCIBLE GAS INJECTION WELLS TO IMPROVE
RECOVERY FACTOR

The "REN" field has produce from August 1997 until December 2022. This field
has 12 wells, with 7 shut-in wells, 4 oil production wells, and 1 gas injection well.
The OOIP in this layer is 26.83 MMSTB, with cumulative production by December
2022 at 6.26 MMSTB and a recovery factor of 23.30%. This study aims to determine
the most optimal field development scenario using the immiscible gas injection well
conversion method.
The process begins with data preparation, which includes the static reservoir
model, reservoir characteristics data, and production data. This is followed by
processing routine core analysis (RCAL), special core analysis (SCAL), and
reservoir fluid PVT data. After that, initialization, history matching, and PI
matching are performed to validate the simulation model. The field development
scenario is then carried out by determining the injection pattern, injection rate
sensitivity, and optimal injection pressure for immiscible gas injection.
The best-selected scenario is Scenario 3D, which involves the sensitivity of the gas
injection rate based on Scenario 1B that uses a five-spot pattern. However, the gas
injection rate used is 4.000 MSCF/D, based on the assumption that gas is abundant
in the "REN" Field. The cumulative oil production generated is 7,50 MMSTB, with
a recovery factor of 27,97%, an increase in the recovery factor by 3,8%, and a
watercut of 90,47%.
