Abstract
Penelitian yang bertujuan untuk mengestimasikan distribusi lateral reservoar batupasir gas pada Formasi Gumai menggunakan metode AVO analysis dan Multi Atribut seismik. Penelitian ini mencakup processing data seismik dan data sumur. Metode geofisika yang digunakan pada data seismik ialah AVO Analysis, spectral decomposition dan multi attributes seismik (RMS Amplitude, Sweetness) sedangkan pada data sumur metode yang digunakan ialah analisa petrofisika. Penelitian ini menunjukkan bahwa hasil dari kombinasi analisa pada data sumur dan data seismik ini ialah didapatkan ketebalan reservoar sand pada Formasi Gumai ialah net reservoar 4 meter, net pay 3 meter. sedangkan pada data seismik didapatkan peta distribusi lateral reservoar batupasir gas Formasi Gumai dengan arah barat laut-tenggara. Hasil dari masing-masing tahap analisa pada data seismik ini ialah, dari analisa AVO didapatkan wilayah ini berada pada klasifikasi AVO kelas-1. Pada proses analisa multi atribut seismik RMS amplitude dan sweetness didapatkan persebaran lateral reservoar batupasir gas yang memiliki orientasi north west-south east. sedangkan pada proses analisa spectral decomposition ini dilakukan untuk memvalidasi atau memperkuat hasil dari interpretasi multi attributes seismik, AVO analysis dan petrophysics analysis.

The research is conducting to estimate the lateral distribution of reservoir gas sandstones in Gumai Formation using AVO analysis and multi attribute seismic. This study were include the processing of seismic data and well data. The Geophysical methods which used in seismic data is AVO Analysis, spectral decomposition and multi seismic attributes (RMS Amplitude, Sweetness), while the processing of well data is petrophysical analysis. The research found that the combination of analysis of the well data and seismic data is to obtained thickness of net reservoir is 4 meters, while net pay is 3 meters. The seismic data is to obtained a lateral map distribution of gas sandstone reservoir in Gumai Formation with direction is nort west-south east. The results of analysis is seismic data with AVO analysis methode is AVO class-1. In the process of multi seismic attribute analysis and sweetness obtained RMS amplitude distribution of gas sandstone reservoir lateral orientations north west-south east , whereas the spectral decomposition analysis process is performed to validate or reinforce the results of multi attributes seismic interpretation, petrophysics analysis and AVO analysis.
