Ultrasonic and electrical properties of hydrate-bearing sediments
There is a need to estimate the amount of gas hydrates occurring in the subsurface to establish the potential of natural gas hydrates as, for example, gas resource, geo-hazards, or climate change factors. Controlled laboratory measurements of the seismic properties of pure hydrate and hydrate-bearing sediment are critical to calibrate seismic and more importantly well-logging methods used to estimate gas hydrate accumulations. In general, the presence of hydrates is accompanied by an increase in acoustic velocity and attenuation. The stiffening effect of hydrate formation in unconsolidated ...
