Seismic Studies for Gas Hydrate Characterization in a Marine Case

Article Preview

Abstract:

We combine an integrated study of gas hydrate reservoirs in a marine area from seismic data which collected for oil and gas exploration purpose. This study combines analyses of geology and seismology. First, geological analysis is made using data of material sources, structures and sediments to determine the hydrocarbon formation conditions of gas hydrate. Then seismic amplitude attributes analysis is conducted to predict the potential existence of four types of BSR in this area. Finally, pre-stacked inversion is conducted to predict the potential existence of hydrate and its free gas. Results show that gas hydrate is widely distribute in this area, and the distribution controlled by material source, reservoir space, and geothermal conditions.
