Pore space hydrate formation in a glass bead sample from methane dissolved in water

[1] An experimental device designed and developed to grow methane hydrate in the pore space of a sediment was successfully used with a glass bead sample. The underlying idea for the experiment is that methane dissolved in water is transported with upward moving fluids from its place of origin at greater depths to formations within the hydrate stability field where the methane is removed from the pore water to form hydrate. This process is simulated in a closed loop flow system where methane charged water from a gas/water reservoir outside the hydrate stability field is pumped into the sediment sample cell in the stability field for methane hydrate. The fluid depleted of methane, then flows back into the gas/water reservoir to be recharged with methane. When the experiment was terminated due to blockage of flow by hydrate formation, hydrate saturation was about 95%.
