In recent decades, the Chilean margin has been extensively investigated to better characterize the complex geological setting through the geophysical data. The analysis of seismic lines allowed us to identify the occurrence of gas hydrates and free gas i...

Natural gas hydrate is an important energy source. Therefore, it is extremely important to provide a clear imaging profile to determine its distribution for energy exploration. In view of the problems existing in conventional migration methods, e.g., the...

The theoretical gas hydrates stability zone (GHSZ) in the Ross Sea area was evaluated by mean of a
steady state simple approach by using bathymetric data, sea bottom temperature, a variable geothermal gradient and
assuming that the natural gas is methane...

Coastal areas are generally characterized by human manufacturing; thus, seismic data analysis is necessary to characterize the properties of the subsoil, the main purpose of which is to clarify risk situations. In the case of very shallow water environme...

In this study one seismic section offshore Chiloé Island was analyzed to better define the seismic character
of the hydrate-bearing sediments. The velocity analysis was used to estimate the gas-phase concentration and relate it to
the geological features...

A gas hydrate reservoir, identified by the presence of the bottom simulating reflector, is located offshore of the Antarctic Peninsula. The analysis of geophysical dataset acquired during three geophysical cruises allowed us to characterize this reservoi...
