Abstract
Imidazoline-derived compounds are used in compositions and methods for inhibiting natural gas hydrate agglomerates. The imidazoline-derived compounds are reaction products between a tall oil fatty acid and an amine. The methods include introducing a composition downhole, the composition comprising an imidazoline-derived compound formed by reacting a tall oil fatty acid with an amine; and contacting the composition with a downhole fluid to inhibit formation of hydrate agglomerates, wherein the downhole fluid comprises natural gas or hydrocarbons.
