AbstractMethane hydrate was formed in an unconsolidated bed of silica sand and the process was monitored with magnetic resonance imagin g. The sand particle size and the water content were varied and their effect on hydrate nucleation and growth was observed. It was found that hydrate formation in porous media does not proceed in a uniform manner and nucleation of hydrate crystals occurs at different times and different positions inside the bed, a phenomenon which is referred to as multiple nucleation in space and time. Furthermore, hydrate formation was found to be faster in a bed with lower water content and smaller particle size.
