Experimental Measurement of Gas Hydrate Stability in Porous Media

P567 EXPERIMENTAL MEASURMENT OF GAS HYDRATE STABILITY IN POROUS MEDIA 1 ROSS ANDERSON ROD W. BURGASS BAHMAN TOHIDI and KASPER K. ØSTERGAARD Centre for Gas Hydrate Research Department of Petroleum Engineering Heriot-Watt University Edinburgh EH14 4AS UK SUMMARY: New data for the stability zone of methane and CO2 hydrates in 82 Å diameter porous media are reported. The data is combined with that previously measured for 128 Å and 251 Å as part of an ongoing study of hydrate stability in porous media [Tohidi et al. 2000b] and a comprehensive correlation between pore size and hydrate inhibition is presented.
