Abstract

Compositions and methods of using of such compositions to, for example, inhibit of the formation of gas hydrate agglomerates are provided. In one embodiment, the methods comprise: introducing a low-dosage hydrate inhibitor additive into a fluid, wherein the low-dosage hydrate inhibitor additive comprises a quaternary or tertiary ammonium cation moiety, a lipophilic tail, and a sulfonate anion moiety; and exposing the low-dosage hydrate inhibitor additive to a temperature above about 200° F.
