Abstract

Cekungan Natuna Barat merupakan salah satu cekungan penghasil hidrokarbon di Indonesia, dimana penelitian ini berfokus pada Formasi Upper Gabus, Lapangan Anoa. Pemilihan Formasi Upper Gabus sebagai fokus area penelitian karena Formasi Upper Gabus sendiri sudah menjadi target utama eksplorasi di Cekungan Natuna Barat. Pemilihan penggunaan atribut seismik amplitudo RMS dapat menentukan area reservoir dengan mengestimasi kontak. Dalam mencari informasi reservoir melalui sinyal seismik yang dapat dilakukan menggunakan amplitudo yang membantu dalam proses perhitungan cadangan hidrokarbon. Perhitungan cadangan hidrokarbon pada Formasi Upper Gabus dilakukan dengan
metode Volumetrik dengan persamaan OGIP. Dari hasil well seismic tie picking selesai dilakukan, maka didapatkan peta kontur waktu kemudian didapatkan peta kontur kedalaman.
Dilakukan perhitungan volumetrik untuk mengetahui cadangan hidrokarbon didaerah penelitian.
Berdasarkan hasil korelasi data sumur terdapat daerah potensial hidrokarbon di Lapangan Anoa pada sumur WL-1, AQ-4X dan AQ-2X dari Top UG-3 sampai Base UG-3, sedangkan
tidak ada daerah potensial pada UG-1 dan UG-2 karena tidak terdapat data yang persis melewati UG-1 dan UG-2. Sebaran ekstraksi amplitudo RMS dapat digunakan untuk menentukan area reservoir dengan mengestimasi kontak, sehingga didapatkan perhitungan volumetrik pada Lapangan Anoa memiliki potensial cadangan gas sebesar 1.287 Bscf di UG-1, 3.2 Bscf di UG�2, 16.106 Bscf di UG-3.

The West Natuna Basin is one of the hydrocarbon-producing basins in Indonesia, where this research focuses on the Upper Gabus Formation, Anoa Field. The Upper Gabus Formation
was chosen as the focus of the research area because the Upper Gabus Formation itself has become the main target of exploration in the West Natuna Basin. The choice of using the RMS amplitude seismic attribute can determine the reservoir area by estimating the contact. In searching for reservoir information through seismic signals, it can be done using an amplitude that helps in the process of calculating hydrocarbon reserves. Calculation of hydrocarbon
reserves in the Upper Gabus Formation is carried out using the Volumetric method with the OGIP equation. From the results of the well seismic tie picking, the time contour map is obtained and then the depth contour map is obtained. Volumetric calculations were carried out to determine the hydrocarbon reserves in the research area.
Based on the results of the well data correlation, there are potential areas for hydrocarbons in the Anoa Field in the WL-1, AQ-4X and AQ-2X wells from Top UG-3 to Base UG-3, while there is no potential area in UG-1 and UG-2 because there are no data that exactly crosses UG�1 and UG-2. The RMS amplitude extraction distribution can be used to determine the reservoir area by estimating the contact, so that the volumetric calculation in Anoa Field has a potential gas reserve of 1,287 Bscf in UG-1, 3.2 Bscf in UG-2, 16,106 Bscf in UG-3.
