Abstract
Abstract: Elastic wave velocity is the key parameter in determining the quantity of gas hydrate in sediment. Using data acquired in permafrost, elastic responses of gas hydrate bearing sediment are examined in detail by fitting observed elastic wave velocities of VSP and logging data with computed velocities based on two opposing gas hydrate bearing models. It is concluded that observed elastic wave velocity best fits a model of gas hydrate disseminated in pore space, without assuming cementation on grain boundaries in model simulations. This conclusion is important in the sense that shear wave velocity is crucial in determining gas hydrate bearing model and estimating gas hydrate saturation rate in pore space. The current case is the first example in model determination by reliable elastic wave velocity observed in the field.
