"Penelitian pada Cekungan Sumatera Utara telah dilakukan dengan tujuan untuk mengevaluasi efektivitas metode Pseudo 3D Seismik menggunakan algoritma Simulasi Gaussian Sekuensial (SGS) dalam mendelineasi geometri zona karbonat Formasi Tampur. Hal ini dikarenakan keterbatasan kemampuan data 2D dalam mendeleniasikan batasanbatasan fasies yang menyusun carbonate buildup. Peneliti menggunakan 38 lintasan seismik 2D PSTM yang tersebar pada area studi ini. Peneliti membangun volume pseudo 3D melalui proses gridding, injeksi amplitudo, dan interpolasi berbasis model peta struktur pada domain waktu. Peneliti menganalisis volume pseudo 3D menggunakan atribut seismik RMS Amplitude dan edge detection untuk mengidentifikasi batas fasies karbonat. Hasil interpretasi menunjukkan bahwa metode SGS mampu memetakan reef core dan reef margin yang menyusun dari carbonate buildup. Peneliti juga mengidentifikasi komponen sistem petroleum (batuan induk, reservoir, dan penutup) berdasarkan hasil interpretasi spasial dari volume pseudo 3D. Hasil penelitian membuktikan bahwa metode SGS efektif untuk membangun model spasial bawah permukaan pada wilayah studi di lepas pantai Cekungan Sumatera Utara.

Research in the North Sumatra Basin was carried out with the aim of evaluating the effectiveness of the Pseudo 3D Seismic method using the Sequential Gaussian Simulation (SGS) algorithm in delineating the geometry of the carbonate zone of the Tampur Formation, this is due to the limited ability of 2D data in delineating the facies boundaries that make up the carbonate buildup. Researchers used 38 2D PSTM seismic trajectories spread across this study area. Researchers built pseudo 3D volumes through a process of gridding, amplitude injection, and model-based interpolation of structure maps in the time domain. Researchers analyzed the 3D pseudo volume using the RMS Amplitude and edge detection seismic attributes to identify carbonate facies boundaries. The interpretation results show that the SGS method is able to map the reef core and reef margin that make up the carbonate buildup. Researchers also identified the components of the petroleum system (source rock, reservoir and cover) based on the results of spatial interpretation of the 3D pseudo volume. The research results prove that the SGS method is effective for building subsurface spatial models in the study area off the coast of the North Sumatra Basin."
