Penelitian ini dilakukan dengan tujuan untuk melakukan reinterpretasi zona prospek
hidrokarbon pada Sumur ALV-1 yang terletak di Kabupaten Bulungan, Provinsi
Kalimantan Utara. Sumur ini berada dalam wilayah Cekungan Tarakan. Zona
prospek hidrokarbon pada sumur ini sebenarnya telah diidentifikasi sebelumnya,
namun penelitian ini difokuskan untuk meninjau kembali atau melakukan
reinterpretasi terhadap hasil tersebut berdasarkan analisis data log sumur secara
lebih mendalam. Langkah ini dilakukan guna memperoleh gambaran yang lebih
komprehensif mengenai karakteristik reservoir dan untuk memastikan kembali
potensi hidrokarbon yang terdapat pada interval-interval tertentu, sehingga dapat
mendukung pengambilan keputusan dalam tahapan pengembangan lapangan ke
depan.
Penelitian ini dilakukan untuk mendapatkan hasil analisa petrofisik terhadap sumur
"ALV-1" agar diperoleh nilai parameter fisik dari lapisan prospek serta nilai in
place kemudian mengusulkan kandidat lapisan yang cocok untuk dilakukannya
produksi minyak. Analisa yang dilakukan berupa analisa secara kualitatif kemudian
dilanjutkan dengan analisa kuantitatif yaitu untuk memperoleh parameter
parameter seperti kandungan shale (Vsh) sebagai koreksi terhadap ketebalan bersih
reservoir, porositas (Φ) sebagai penyimpanan fluida reservoir, serta saturasi air
(Sw) yang digunakan untuk mengetahui jumlah net pay yang mengandung
hidrokarbon.
Setelah dilakukan analisa petrofisik secara kualitatif dan kuantitatif berupa
perhitungan volume shale, porositas, dan saturasi air pada Sumur "ALV-1",
didapatkan 10 zona prospek mengandung hidrokarbon kemudian ditentukan nilai
cut off porositas sebesar 0.1, cut off volume shale sebesar 0.4, dan cut off nilai
saturasi air sebesar 0.8 yang menghasilkan reservoir lumping. Setelah dilakukan
perhitungan in place menggunakan metode well basis didapatkan jumlah cadangan
minyak mula-mula sebesar 1.205 MMSTB dan cadangan gas sebesar 1.511 Bscf.
Kata kunci: analisa petrofisik, zona prospek, oil in place, gas in place.

ABSTRACT
DETERMINATION OF HYDROCARBON PROSPECT ZONES
BASED ON THE INTEGRATION OF WELL LOG DATA, CORE
DATA AND PETROPHYSICAL ANALYSIS OF WELL ALV-1 RM

This research aims to reinterpret the hydrocarbon prospect zones in Well ALV-1,
located in Bulungan Regency, North Kalimantan Province. The well lies within the
Tarakan Basin. Although the hydrocarbon prospect zones in this well have been
previously identified, this study focuses on re-evaluating or reinterpreting those
results through a more detailed analysis of well log data. This step is intended to
obtain a more comprehensive understanding of the reservoir characteristics and to
reassess the hydrocarbon potential within specific intervals, thereby supporting
better decision-making in future field development planning.
This study was conducted to obtain the results of petrophysical analysis of the
"ALV-1" well in order to obtain the physical parameter values of the prospect layer
and the in-place value and then propose candidate layers that are suitable for oil
production. The analysis carried out was in the form of qualitative analysis
followed by quantitative analysis, namely to obtain parameters such as shale
content (Vsh) as a correction to the net thickness of the reservoir, porosity (Φ) as
reservoir fluid storage, and water saturation (Sw) which is used to determine the
amount of net pay containing hydrocarbons.
After conducting qualitative and quantitative petrophysical analysis in the form of
shale volume, porosity, and water saturation calculations in the "ALV-1" Well, 10
prospective zones containing hydrocarbons were obtained, then the porosity cut
off value was determined at 0.1, the shale volume cut-off was at 0.4, and the water
saturation cut-off value was at 0.8 which resulted in a lumping reservoir. After
inplace calculations using the well basis method, the initial oil reserves were
obtained at 1.205 MMSTB and gas reserves at 1.511 Bscf.
Keywords: petrophysical analysis, prospect zone, oil in place, gas in place.
