Methane hydrate self-preservation features in oil suspensions

[摘要] Features of methane hydrate self-preservation in the dispersions prepared from water in oil emulsions from two deposits in East Siberia were studied. Under experimental conditions, substantial self-preservation of the hydrate is observed in the dispersion based on oil 1, while the effect is weakened in the dispersions based on oil 2. It is demonstrated that the observed difference is connected with the presence of Span 80 surfactant in water in oil 2 emulsion.
