 Abstrak

[ABSTRAK
Aplikasi atribut seismik 3D dan sifat fisik batuan telah dapat memodelkan reservoar A
Formasi Ledok Lapangan X Blok Cepu. Beberapa atribut seismik yang sesuai untuk
mengidentifikasi penyebaran reservoar dilapangan ini adalah root mean square (rms),
sweetness, dan impedansi akustik relatif. Dimana ketiga atribut seismik tersebut
memperlihatkan suatu anomali amplitudo berupa bright spot yang diidentifikasi sebagai
reservoar A dan memperlihatkan pola penyebaran berarah selatan-utara. Fasies reservoar
A yang merupakan batugamping pasiran adalah reservoar yang sangat baik dalam
menyimpan hidrokarbon gas dengan porositas 19% dan saturasi air sebesar 40%. Adanya
faktor ketidakpastian dalam penentuan batas penyebaran reservoar A dari atribut seismik,
model reservoar A di bagi menjadi tiga bagian yaitu perkiraan optimis (P90), perkiraan
sedang (P50) dan perkiraan pesimis (P10). Keberadaan hidrokarbon gas di Lapangan X
dikontrol oleh suatu perangkap stratigrafi bukan perangkap struktur hal ini terlihat dari
tidak adanya tutupan (klosur). Berdasarkan sebaran reservoar melalui integrasi atribut
seismik, properti batuan dan model reservoar diusulkan 4 (empat) sumur pemboran untuk
mengembangkan lapangan gas X.

ABTRACT
Application of 3D seismic attributes and physical properties of reservoir rocks have been to
model the formation Ledok A Field X Cepu Block. The seismic attributes, which can be used
to identify distribution of the reservoir in this field were the root mean square (rms),
sweetness, and relative acoustic impedance. The attributes of the seismic amplitude anomaly
shows a bright spot in the form identified as reservoars A and show the pattern of northsouth
trending deployment. A reservoir facies which is a sandy limestone reservoir was very
good at keeping a hydrocarbon gas with 19% porosity and water saturation of 40%. The
existence of uncertainty in the determination of reservoir distribution limit of seismic
attributes. A reservoir model was divided into three parts, optimistic estimate (P90),
moderate estimate (P50) and pesimistic estimate (P10). The existence of hydrocarbon gases
in field X in was control by a stratigraphic traps compared to traps structure as seen from
the absence of cover (closur). Based on integration of seismic attributes, rock properties and
reservoar model proposed four (4) wells drilling to develop the gas field X.;Application of 3D seismic attributes and physical properties of reservoir rocks have been to
