Sumur RG-01 merupakan sumur yang berada pada Lapangan RGA yang terletak di
cekungan Sumatera Tengah. Sumur ini menembus formasi Bekasap pada kelompok
Sihapas. Sumur RG-01 tergolong sebagai sumur minyak dari hasil yang didapatkan dari
data test sumur. Kegiatan wireline logging pada Sumur RG-01 sehingga didapatkan hasil
berupa data LAS, selain itu terdapat data well test, header log, analisa air, dan sample
core. Dari data yang ada akan dilakukan analisa petrofisika untuk menentukan jenis fluida
dan besarnya In place hidrokarbon pada Sumur RG-01.
Analisa petrofisika dilakukan dengan melakukan pengumpulan data, pengolahan data,
analisa kualitatif, analisa kuantitatif, analisa cut off, reservoir lumping, dan yang terakhir
melakukan perhitungan cadangan mula-mula atau In Place pada Sumur RG-01.
Hasil dari analisa petrofisik yang dilakukan adalah mendapatkan parameter-parameter
seperti Vshale, porositas, saturasi air, dan permeabilitas. Untuk nilai Vshale rata-rata
didapatkan sebesar 20 %, kemudian untuk porositas rata-rata sebesar 21 %, sedangkan
untuk saturasi air sebesar 48 %. Untuk volume bulk menggunakan metode well basis dan
didapatkan nilai sebesar 40899.54 acre-ft. Kemudian untuk nilai boi yang ada sebesar
1.15 bbl/STB
Cadangan mula-mula atau In Place pada sumur RG-01 dapat dihitung dengan parameter
yang telah didapatkan, sehingga didapatkan OOIP sebesar 31.83 MMSTB.

ABSTRACT
PETROPHYSICS ANALYSIS IN DETERMINING THE “RGA”
FIELD HYDROCARBON PROSPECT ZONE

The RG-01 well is a well located in the RGA Field which is located in the Central Sumatra
basin. This well penetrates the Beksap formation in the Sihapas group. The RG-01 well is
classified as an oil well from the results obtained from the well test data. Wireline logging
activities on the RG-01 well so that results are obtained in the form of LAS data, besides
that there are well test data, log headers, water analysis, and sample cores. From the
existing data, a petrophysical analysis will be carried out to determine the type of fluid and
the amount of hydrocarbon reserves in the RG-01 Well.
Petrophysical analysis is carried out by collecting data, processing data, qualitative
analysis, quantitative analysis, cut off analysis, reservoir lumping, and finally calculating
the initial reserves or In Place at the RG-01 Well.
The results of the petrophysical analysis carried out are obtaining parameters such as
Vshale, porosity, water saturation, and permeability. The average Vshale value is 20%,
then the average porosity is 21%, while the water saturation is 48%. For bulk volume using
the well basis method and obtained a value of 40899.54 acre-ft. Then for the existing boi
value of 1.15 bbl/STB
Initial reserves or In Place in the RG-01 well can be calculated with the parameters that
have been obtained, so that an OOIP of 31.83 MMSTB is obtained.
