Composition and method for producing a pumpable hydrocarbon hydrate slurry at high water-cut

Image Number 4 for United States Patent #7958939.

Embodiments of the invention relate to a process for providing a pumpable hydrate slurry in a hydrocarbon pipeline fluid mixture having a water-cut greater than about 50 volume percent. In one or more embodiments the process comprises treating the fluid mixture with an anti-agglomerant and adding water to the fluid mixture in an amount sufficient to lower the gas-water ratio sufficiently to achieve a pumpable hydrate slurry. Also disclosed are methods for producing hydrocarbons utilizing a process for providing a pumpable hydrate slurry in a hydrocarbon pipeline fluid mixture having a water -cut greater than about 50 volume percent.
