Cekungan Jawa Barat Utara merupakan salah satu cekungan di Indonesia yang
sudah berproduksi, terbagi ke dalam beberapa sub-cekungan, salah satunya sub
cekungan Jatibarang. Pada cekungan ini tersusun atas beberapa formasi, salah
satunya Formasi Cibulakan Atas yang dicirikan dengan litologi silisiklastik
glaukonitan serta terdapat karbonat yang berkembang. Formasi ini menyimpan
cadangan minyak dan gas yang berpotensi sehingga perlu dilakukannya analisis
bawah permukaan untuk mengetahui kondisi bawah permukaan serta perhitungan
cadangan hidrokarbon melalui pemodelan statis reservoir pada salah satu interval
dengan litologi karbonat. Dalam melakukan penelitian ini, metode penelitian yang
digunakan terbagi menjadi dua yaitu analisis kualitatif meliputi analisis log sumur
dan interpretasi seismik, serta analisis kuantitatif meliputi analisis petrofisika dan
pemodelan statis reservoir. Berdasarkan hasil analisis pada data sumur, ditemukan
litofasies antara lain wackestone to floatstone, wackestone to packstone, grainstone,
mudstone to wackestone, dan shale, yang terbagi ke dalam beberapa asosiasi fasies
meliputi outer ramp, middle ramp, inner ramp, dan outer ramp deep basin. Pada
interval penelitian, ditemukan beberapa marker stratigrafi meliputi FS 1, FS 2, FS
3, FS 4, FS 5, FS 6, dan SB 1. Reservoir pada interval ini diinterpretasikan
diendapkan pada lingkungan shallow inner-middle sublittoral. Berdasarkan hasil
perhitungan cadangan hidrokarbon, didapatkan nilai gas in place sebesar 10,52696
BSCF dan oil in place sebesar 23,11 MMSTB.

ABSTRACT
HYDROCARBON RESERVES CALCULATION THROUGH
RESERVOIR STATIC MODELLING OF LAYER X, “VON”
FIELD, UPPER CIBULAKAN FORMATION,
NORTHWEST JAVA BASIN

The North West Java Basin is one of Indonesia's productive basins and is divided
into several sub-basins, one of which is the Jatibarang Sub-basin. This basin
comprises several formations, including the Upper Cibulakan Formation, which is
characterized by glauconitic siliciclastic lithology and the development of
carbonates. This formation holds potential oil and gas reserves, necessitating
subsurface analysis to understand the geological conditions and perform
hydrocarbon reserve calculations through static reservoir modeling within a
carbonate lithology interval. The research methodology used in this study is divided
into two approaches: qualitative analysis, which includes well log analysis and
seismic interpretation, and quantitative analysis, which includes petrophysical
analysis and static reservoir modeling. Based on the analysis of well data, the
identified lithofacies include wackestone to floatstone, wackestone to packstone ,
grainstone, mudstone to packstone, and shale, which then divided into several
facies association including outer ramp, middle ramp, inner ramp, and outer ramp
deep basin. The reservoir interval is bounded by FS 1 at the bottom of the reservoir
and is also found FS 2, FS3, FS 4, FS 5, FS 6, and SB 1. The reservoir on this
interval is interpreted to have been deposited in a shallow inner to middle
sublittoral environment. Based on hydrocarbon reserve calculations, the estimated
gas in place is 10.52696 BSCF, and the oil in place is 23.11 MMSTB.
