Gas hydrate detection in the Iranian sector of the Oman Sea: application of AVO and seismic pattern recognition methods
Sarmadi Doost, M., Erfani, F., Hashemi, H., Sokooti, M. and Sadiq-Arabani, M., 2013. Gas hydrate detection in the Iranian sector of the Oman Sea: application of AVO and seismic pattern recognition methods. Journal of Seismic Exploration, 22: 339-351. Gas hydrates attracted worldwide attention because of their potential as a new energy reserve in recent years. Therefore their exploration is essential for the strategic future of the world as a new form of energy. In this research we use pre-stack seismic attributes to identify elastic properties of the host sediments in the vicinity of the gas hydrate zone. AVO analysis of pre-stack seismic data is used as a powerful interpretation technique. Moreover, attributes derived in the post-stack seismic domain are used successfully to make a separation between hydrate and non-hydrate sediments by applying pattern recognition and classification methods. It is found that both AVO analysis and seismic pattern recognition techniques are meaningful on a gas hydrate potential zone in the Oman Sea. An integrated scheme is presented for studying similar areas based on joint use of AVO and post-stack attribute analysis.
