Patent ID: 7842508

Claim:
A method for determining the gas hydrate anti-agglomeration power in an emulsified water-in-oil system in the presence of a gas, comprising: conducting at least two successive cycles of hydrate formation and dissociation by cooling and reheating a sample of said emulsified water-in-oil system placed in the cell of a calorimeter wherein (A) during hydrate/dissociation, a thermogram is recorded on which a peak of a curve or any other dimension linked to the peak area under the peak is identified, the peak area being characteristic of the quantity of hydrates formed; (B) during dissociation of the hydrates in a successive cycle or cycles, identifying in the thermograms a peak, the peak area under said peak or any other dimension linked to the peak area is characteristic of the quantity of hydrates formed; and from the change in peak areas under successive (A) and (B) peaks, determining the gas hydrate anti-agglomeration power of the sample, a reduction in said peak area or said other dimension linked to the peak area revealing a weak anti-agglomeration power and conservation of said peak area or said other dimension linked to the peak area revealing a strong anti-agglomeration power.
