Wijaya, Lita Anjani (2017) Penentuan Struktur Dan Stratigrafi Seismik Zona Reservoir Dengan Menggunakan Metode Multi Atribut Pada Lapangan Penobscot, Nova Scotia Canada. Sarjana thesis, Universitas Brawijaya.
Abstract
Daerah penelitian adalah lapangan Penobscot, Nova Scotia Canada. Survei seismik lapangan penelitian dilakukan dalam bentuk data seismik 3D, didukung oleh dua data sumur yaitu L-30 dan B-41. Tujuan dilakukan analisa seismik multi atribut ini untuk mengetahui struktur dan stratigrafi zona reservoir pada Formasi Missisauga (Upper Missisauga, O-Marker, dan Lower Missisauga). Metode yang digunakan antara lain yaitu, Amplitudo RMS, Koherensi, dan Dekomposisi Spektral. Berdasarkan hasil penelitian menggunakan atribut RMS, disimpulkan bahwa distribusi reservoir batu pasir ditunjukan dengan nilai kontras amplitudo yang tinggi. Analisa struktur sesar dilakukan dengan menggunakan metode Koherensi, di mana metode ini dapat memetakan struktur bawah permukaan dengan mempertegas event-event sesar yang ada di ketiga horizon tersebut. Arah sesar daerah penelitian berorientasi pada Barat ke Timur dan jenis sesar berupa sesar normal. Berikutnya penentuan stratigrafi reservoir daerah penelitian dilakukan dengan menggunakan metode Dekomposisi Spektral yang menghasilkan analisa stratigrafi berupa channel.
English Abstract
The research has been done in Penobscot field, Nova Scotia Canada. This seismic research survey was conducted in the form of 3D seismic data, supported by data taken from two wells L-30 dan B-41. The purpose of this attributes seismic analysis are to know the structure and stratigraphy of the reservoir Formation Missisauga (Upper Missisauga, O-Maker, and Lower Missisauga). The methods used are Amplitude RMS, Coherence and Spectral Decomposition. Based on research results using RMS attributes, it is concluded has a sandstone reservoir distribution shown by high amplitude contrast value. Fault section analysis is done by using Coherence method. This method can map the sub-surface structure by reinforcing the fault events in the three horizons. The direction of the fault area is oriented toward the West to the East and the type is normal fault. Furthermore, the determination of reservoir area stratigraphy is done by using Spectral Decomposition method, which produce stratigraphic analysis in the form of channel.
