Abstract
Low-dosage hydrate inhibitor (“LDHI”) compounds comprising multiple lipophilic tails and a hydrophilic head may be employed into fluids to inhibit agglomeration of hydrates, among other things. Suitable hydrophilic heads may include quaternary or tertiary ammonium cation moieties, and combinations thereof. Such LDHI compounds in some embodiments may include reaction products of DETA and/or other amines, fatty acid(s), and, optionally, alkyl halide(s). Compounds according to some embodiments may be employed in fluids in various environments, such as a conduit penetrating a subterranean formation, or a conduit carrying fluid in an industrial setting.
