The article discusses experiments to study the acoustic properties of samples from hydrophobic quartz sand containing methane hydrate. It is shown that in this case the P and S-wave velocities are close to the data on the velocities in samples containing a non-cementing type hydrate, which is typical for natural samples. This method is an alternative to the so-called “water excess” method for the rapid formation of sand samples containing non-cementing methane hydrate.
