Abstract:
Gas hydrates attracted worldwide attention due to their potential as huge energy resource in the recent decades. Therefore identifying and prospecting them is essential for strategic hydrocarbon reservoir management. Seismic methods are known as a powerful gas hydrate exploration methodology. In this research pre-stack seismic attributes have been used to identify elastic properties and qualitative hydrate saturation of sediments. Using AVO analysis on pre-stack seismic data, occurrence of gas hydrate has been confirmed in the Oman Sea. Also post-stack seismic meta-attributes (applying pattern recognition and classification methods on several attribute planes) have been successfully used to make separation between hydrate and non-hydrate sediments. Joint use of pre- and post-stack seismic attributes will be a good evaluation techniques for confirmation of this study.
