Sadiyanti, Anissa (2018) Analisis Karakteristik Reservoir Menggunakan Metode Seismik Inversi Dan Atribut Pada Lapangan “ROSARE”, Cekungan Salawati, Papua Barat. Sarjana thesis, Universitas Brawijaya.
Abstract
Cekungan Salawati adalah salah satu cekungan yang mampu memproduksi hidrokarbon pada Indonesia bagian timur. Target penelitian pada lapangan “Rosare” adalah reservoir batuan karbonat pada formasi Kais. Pada penelitian digunakan data seismic 3D dan satu buah data sumur RSR A-1. Interpretasi data seismik yang dilakukan untuk mengetahui karakter dari reservoir penelitian. Metode yang digunakan dalam penelitian adalah seismik inversi berbasis model dan atribut seismik seperti RMS dan Sweetness. Hasil yang diperoleh dari penelitian adalah peta struktur waktu juga kedalaman dari reservoir penelitian, peta persebaran atribut RMS dan Sweetness, serta porositas dari hasil inversi. Hasil inversi menunjukkan bahwa porositas pada reservoir penelitian bernilai 19%. Sementara hasil atribut RMS dan Sweetness menunjukkan pada lapangan penelitian memiliki porositas bagus yang terisisi oleh hidrokarbon. Nilai hasil atribut selanjutnya disebarkan pada petastruktur waktu untuk mengetahui letak zona dengan anomali atribut tinggi di lapangan “Rosare”. Anomali tinggi hasil RMS yang diperoleh pada lapangan “Rosare” berkisar antara 11 hingga 15 ms. Sementara anomali tinggi hasil Sweetness berkisar antara 3,25 hingga 5,50 ms. Rekomendasi zona pemboran baru didapatkan dari analisis atribut RMS dan Sweetness. Rekomendasi zona ini berada di bagian tenggara hingga selatan sumur penelitian RSR A-1.
English Abstract
Salawati basin is one of basin that able produce hydrocarbon in East part of Indonesia. The goal of this research in “Rosare” field is carbonar reservoir in Kais formation. This research uses 3D seismic data and well RSR A-1 data. Seismic data interpretation which has been used to find out the character of reservoir research. Method that is being used in this research is seismic inversion model-based and seismic attribute, such as RMS and Sweetness. The result shows that time structure map and the depth of reservoir research, RMS and Sweetness attribute distribution map and priority of inversion result. The Result of inversion shows that priority of reservoir research reaches 19%. In the other hand, the result of RMS and Sweetness attribute shows in research field has good porosity that filled by hydrocarbon. The value result of the next attribute distributed in time structure map to know the zone with high anomali attribute in “Rosare” field. RMS’s result of high anomali that earned in “Rosare” field reached between 11 to 15 ms, meanwhile Sweetness’s result of high anomali reached between 3.25 to 5.50 ms. New drilling zone recommendation is obtained from RMS and Sweetness attribute analysis. This zone recommendation takes place in southeast to south RSR A-1well research.
