Lapangan X terletak di kecamatan Wates kabupaten Bekasi Jawa barat, pada salah
satu sumur injeksi yaitu sumur injeksi E-63 terkorelasi dengan beberapa sumur produksi yaitu
sumur C-07,C-22,D-43,D-56,E-33 dan E-37. Sumur Injeksi E-63 aktif mulai beroperasi pada
tanggal 30 maret 2012 hingga saat ini.Selama kegiatan injeksi air di sumur injeksi E-63 ini
berlangsung dilakukan analisa dengan menggunakan metode Voidage Replacement Ratio
(VRR) di lapisan BRF A-2 dengan tujuan untuk mengetahui seberapa banyak pengaruh yang
dihasilkan sumur injeksi tersebut dalam memproduksikan fluida berdasarkan target Voidage
Replacement Ratio (VRR) di lapisan tersebut.
Langkah awal yang dilakukan dalam penelitian iniantara lain dengan melakukan
pengumpulan data yaitu meliputi data korelasi,trajectory,produksi,dan injeksi. Kemudian
data diinput ke dalam microsoft excel untuk membentuk grafik tiap - tiap sumur sedangkan
data trajectory menggunakan software Petrel 2009 untuk menentukan jarak berdasarkan
kordinat pada masing-masing sumur. Pada penelitian ini juga dilakukan dengan menganalisa
hasil grafik monitoring sumur yang kemudian data produksi sumur-sumur produksi tersebut
dilakukan perhitungan menggunakan persamaan Voidage Replacement Ratio (VRR).
Dalam penelitian diketahui bahwa radius sumur injeksi belum menjangkau sumur
terdekat dan terjauh,sedangkan hasil setiap sumur produksi yang digambarkan pada grafik
dapat dilihat bahwa Trend antara grafik injeksi terhadap grafik produksi menunjukan trend
liquid pada keseluruhan sumur produksi di area pattern alpha rata-rata mengalami penurunan
dan hampir tidak adanya kenaikan produksi liquid, serta hasil perhitungan Voidage
Replacement Ratio (VRR) yang di peroleh pada sumur injeksi air E-63 selama 8 tahun bernilai
0,001219 atau < 1.
Dari hasil penelitian ini disimpulkan bahwa nilai VRR sumur injeksi E-63 jauh sangat
rendah < 1, dan menunjukan bahwa tidak adanya respon kenaikan tekanan sehingga dapat
disimpulkan bahwa performa sumur injeksi E-63 masih kurang berpengaruh pada
keseluruhan sumur produksi yang ada pada area pattern alpha sumur E-63 di lapisan BRF
A-2

Field "X" is located in Wates sub district, Bekasi, West Java, in one of the injection
wells, namely the E-63 injection well, which is correlated with several production wells, these
are wells C-07, C-22, D-43, D-56, E-33 and E-37. E-63 injection well has been actively
operating since March 30, 2012 until now. During the activity that was injected into the E63 injection well, an analysis was carried out using the Voidage Replacement Ratio (VRR)
method in the A-2 BRF layer with the aim of knowing how much the injection well has a lot
of influence in producing fluid based on the Voidage Replacement Ratio (VRR) target in the
layer.
The first steps taken in this research include collecting data, which includes data on
correlation, trajectory, production, and injection. Then the data is inputted into Microsoft
Excel to form a graph for each well, while the trajectory data uses Petrel 2009 software to
determine the distance based on the coordinates of each well. This research was also carried
out by analyzing the results of the well monitoring graph, then the production data of the
production wells was calculated using the Voidage Replacement Ratio (VRR) equation.
In this research it is known that the radius of the injection well has not reached the
nearest and farthest wells, while the results of each production well depicted in the graph can
be seen that the trend between the injection graph and the production graph shows a liquid
trend in all production wells in the alpha pattern area on average decreased and almost no
increase in liquid production, as well as the results of the calculation of the Voidage
Replacement Ratio (VRR) obtained at the E-63 water injection well for 8 years worth
0.001219 or < 1.
From the results of this study, it was concluded that the VRR value of the E-63
injection well was very low < 1, and showed that there was no pressure increase response, so
it can be concluded that the performance of the E-63 injection well still has less effect on the
overall production wells in the alpha pattern area. well E-63 in the BRF layer A-2.
