Patent ID: 7638465

Claim:
A method for inhibiting formation of hydrates comprising: contacting a completion fluid including: brine; and hydrate-forming guest molecules that form hydrates at hydrate forming conditions, where the hydrate-forming guest molecule comprises at least one selected from the group consisting of methane, ethane, ethylene, acetylene, propane, propylene, methylacetylene, n-butane, isobutane, 1-butene, trans-2-butene, cis-2-butene, isobutene, butene mixtures, isopentane, pentenes, natural gas, carbon dioxide, hydrogen sulfide, nitrogen, oxygen, argon, krypton, and xenon, with an amount of kinetic hydrate inhibitor effective to inhibit formation of hydrates at the hydrate forming conditions, where the kinetic hydrate inhibitor is selected from the group consisting of linear polymers and copolymers.
