Laboratory Measurements of Compressional and Shear Wave Speeds through Methane Hydrate
A bstract : Simultaneous measurements of compressional and shear wave speeds through polycrystalline methane hydrate have been made. Methane hydrate, grown directly in a wave speed measurement chamber, was uniaxially compacted to a final porosity below 2%. At 277 K, the compacted material had a comp...

Summary: | A bstract : Simultaneous measurements of compressional and shear wave speeds through polycrystalline methane hydrate have been made. Methane hydrate, grown directly in a wave speed measurement chamber, was uniaxially compacted to a final porosity below 2%. At 277 K, the compacted material had a compressional wave speed of 3,650 ± 50 m/s. The shear wave speed, measured simultaneously, was 1,890 ± 30 m/s. From these wave speed measurements, we derive V p / V s , Poisson's ratio, bulk, shear, and Young's moduli. |
