Relating seismic velocity and attenuation to hydrate saturation in marine sediments is a key first step in this process. To this end, a laboratory resonant column was developed for measuring the seismic properties of methane-hydrate-bearing sediments under simulated in situ conditions. Shear and longitudinal wave velocities and attenuations were measured from the fundamental resonance modes in torsion and flexure of 14-cm-long cylindrical sand specimens (7 cm diameter) in the 50–500 Hz frequency range. Hydrate saturation was varied between 0% and 35% by dispersing known volumes of water throughout the sand and saturating with methane gas before forming hydrate by increasing the pore fluid pressure to 15 MPa and lowering the temperature to −20°C. Subsequent resonant column measurements at 500 kPa effective pressure (5 MPa pore fluid pressure) and 3°C revealed how hydrate cementation rapidly increases seismic velocities and gives rise to an attenuation Q−1 peak at 3%–5% hydrate saturation for P waves and S waves. The VP / VS ratio reduces dramatically from 4.85 (0% hydrate) to 1.86 (35% hydrate). The results are directly applicable to seismic exploration and monitoring of hydrate reservoir sands.
