Methane gas hydrates, crystalline inclusion compounds formed from methane and water,
are found in marine continental margin and permafrost sediments worldwide. This article …

Recent research has established that the dominant P-wave attenuation mechanism in
reservoir rocks at seismic frequencies is because of wave-induced fluid flow (mesoscopic …

Relating pore‐space gas hydrate saturation to sonic velocity data is important for remotely
estimating gas hydrate concentration in sediment. In the present study, sonic velocities of …

We conducted laboratory studies on the geophysical signals from Arctic saline permafrost
soils to help understand the physical and mechanical processes during freeze-thaw cycles …

The energy content of Gas Hydrated in form of natural gas is approximately twice with
respect to the total energy still producible from all the known conventional energy sources …

Compressional wave velocity (Vp) and shear wave velocity (Vs) are important geophysical
parameters for studying gas hydrate systems. However, the Vs parameter is not commonly …

Although elastic velocities (Vp, Vs) can be used to assess the distribution and concentration
of marine gas hydrates in situ and several existing models relate hydrate saturation to …

Sediment cores containing methane hydrate were obtained under pressure from the Eastern
Nankai Trough offshore Japan, and they have been analyzed to investigate the relationship …

Natural gas hydrates in oceanic and permafrost sediments are considered a future energy
resource. Injecting CO 2 into these sediments is believed to aid in the safe and efficient …

To date, very little is known about the distribution of natural gas hydrates in sedimentary
matrices and its influence on the seismic properties of the host rock, in particular at low …
