Velocities and Attenuations of Gas Hydrate-Bearing Sediments
Myung W. Lee
2007, Scientific Investigations Report 2007-5264
Monopole and dipole logging data at the Mallik 5L-38, Mackenzie Delta, Canada, provide a challenge for sonic velocity and attenuation models used to remotely estimate pore-space gas hydrate content. Velocity and attenuation are linked, with velocity dispersion causing increased attenuation. Sonic waveforms for Mallik 5L-38, however, show no velocity dispersion...
