Gas hydrates are the accumulations of methane (natural gas) trapped in ice-like structures with water. Gas hydrates represent an immense energy resource underlying large portions of the world’s marine continental shelves. Vietnam has a large continental shelf area, in the deep water zone with suitable low temperatures and high pressure, which is suitable for the formation and existence of potential energy source of Gas Hydrate (GH). The application of High-Resolution Seismic method (HRS) plays an important role in exploring for Gas Hydrate. The enhancement of HRS research such as optimal short - reception conditions and advanced data processing suitable for Gas Hydrate in shallow layers below the seafloor, allows for determining the geological factors related to Gas Hydrate’s existence in the deep water area. Advancements in data processing technology, such as noise filters (Radon, F-K, SRMA, Tau-P..), seismic attributes analysis, seismic migration, AVO, seismic inversion, pre-stack seismic data and AI technology … allow to identify of the signs of Gas Hydrate presence, such as Bottom Simulated Reflector (BSR), Gas Hydrate Stability Zone (GHSZ), Pockmark, Chimney, etc. This paper presents some of the results obtained from applying High-Resolution Seismic method to predict the distribution of Gas hydrate in the Southeastern offshore of Vietnam.
