The phase diagram for methane + water is explained, in relation to hydrate applications, such as in flow assurance and … in nature. For natural applications, the phase diagram determines the regions for hydrate formation for two- and three …” hydrate sample preparation protocols and testing. …

Three groups of hydrate-bearing sediment samples with/without underlying gas were prepared using a three …-dimensional middle-size reactor to investigate the favorable conditions for methane recovery from hydrate reservoir with gaseous CO2. The … experimental results indicated that hydrate reservoir with underlying free gas, high saturation of free gas and low saturation of …

Effects of 0.29mol% tetra-n-butyl ammonium bromide (TBAB) solution in conjunction with cyclopentane (CP) on the hydrate … induction time of the hydrate formation at the different temperature–pressure conditions. The results show that the volume of …–pressure condition. In addition, the CO2 concentration in the decomposed gas from the hydrate slurry phase reaches approximately 93mol …

of hydrate-bearing sediments govern the hydrate dissociation behavior and gas production process that accompany phase … conductivity of tetrahydrofuran hydrate-bearing sediments. The effects of different porosities, hydrate saturations and porous … materials on the effective thermal conductivity were investigated. The porosity and the hydrate saturation were obtained using …

The porous microstructure of hydrates governs the mechanical strength of the hydrate-bearing sediment. To investigate … the growth law and microstructure of hydrates in porous media, the growth process of tetrahydrofuran (THF) hydrate under … THF hydrate grows as different models under different concentration of THF solution (19%, 11.4% and 5.7% by weight) at 1 …

-derived carbon in shallow sediments overlying the hydrate bearing strata. When integrated with stable carbon isotope ratios of DIC … overlying hydrate bearing strata like those in Alaminos Canyon is critical to quantifying methane flux and estimating methane … hydrate distributions in gas hydrate bearing marine sediments. …

Hydrate formation/dissociation of natural gas in (diesel oil + water) emulsion systems containing 3 wt% anti … linearly with the increase of pressure, and decreases with the increase of water cut. There exists an initial slow hydrate … formation stage for systems with lower water cut, while rapid hydrate formation takes place and the process of the gas …

In this review, the intriguing, anomalous behaviour of hydrate thermal conductivity will be described, and progress in … in the development of detailed theoretical understandings of mechanisms of thermal conduction in clathrate hydrates, and …
