Corrosion inhibitor and kinetic hydrate inhibitor formulations, and methods of using each are provided. Each formulation optionally includes a fluorophore, which can be used to fluorometrically control dosage of each formulation into an aqueous liquid utilized in a downhole application, thereby providing improved precision of dosage into aqueous liquids having relatively high turbidity, and consequently relatively high light absorbance.

Corrosion inhibitors and kinetic hydrate inhibitors

The present invention generally relates to one or more compositions and methods for inhibiting the formation of gas hydrate agglomerates in a fluid. The fluid may be contained, for example, in an oil or gas pipeline or refinery.

Anti-agglomerants for controlling gas hydrates

Disclosed herein are corrosion inhibiting compounds and compositions useful in applications relating to the production, transportation, storage, and separation of crude oil and natural gas. Also disclosed herein are methods of using the compounds and compositions as corrosion inhibitors, particularly in applications relating to the production, transportation, storage, and separation of crude oil and natural gas.
