Abstract: Compounds comprising multiple hydrophilic heads and a lipophilic tail may be employed into fluids to inhibit agglomeration of hydrates, among other things. Suitable hydrophilic heads may include secondary, tertiary, and/or quaternary ammonium cation moieties, phosphonium cation moieties, and combinations thereof. Such LDHI compounds may provide enhanced interactivity with hydrate crystals and/or hydrate-forming molecules. These compounds 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.

Abstract: Methods, compositions, and systems for scale inhibitor squeeze treatments using certain cationic surfactants are provided. In one embodiment, the methods comprise: introducing a pre-flush fluid into at least a portion of a subterranean formation, the pre-flush fluid comprising a cationic surfactant comprising two or more hydrophilic heads, at least one lipophilic tail, and one or more linking groups to which the hydrophilic heads and the lipophilic tail are bonded; and introducing a treatment fluid comprising anionic scale inhibitor into the portion of the subterranean formation after at least a portion of the pre-flush fluid has been introduced into the portion of the subterranean formation.

Abstract: Composition for the removal or inactivation of hydrogen sulfide or soluble sulfide ion other species comprising ionizable sulfur (e.g., mercaptans, thiols, etc.) using compositions containing acrylate and/or derivatives thereof are provided. Methods for the removal or inactivation of hydrogen sulfide or other sulfur species in oilfield sites and other related applications using compositions containing acrylate and/or derivatives thereof are provided.

Abstract: Surfactant compositions for enhancing oil and/or gas production from certain subterranean formations (e.g., unconventional reservoirs), and related methods of use, are provided. In one embodiment, the methods comprise: providing a treatment fluid comprising a carrier fluid and a cationic surfactant comprising at least two hydrophobic heads that each comprise a quaternary cationic moiety; and introducing the treatment fluid into at least a portion of a subterranean formation.

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.

Abstract: Compounds comprising multiple hydrophilic heads and a lipophilic tail may be contacted with a metal or other surface so as to adhere to the surface and inhibit corrosion, among other things. Suitable hydrophilic heads may include quaternary ammonium cation moieties, phosphonium cation moieties, and combinations thereof. Such corrosion-inhibiting compounds may be introduced into a wellbore penetrating at least a portion of a subterranean formation, for instance in oil and/or gas recovery operations and the like, whereupon the compound may adhere to a metal or other surface downhole so as to inhibit corrosion of the surface. These compounds may be employed in various other environments, such as any metal or other surface that may be exposed to corrosive conditions.
