The present disclosure describes solid compositions comprising a paraffin inhibitor and a corrosion inhibitor. The paraffin inhibitors include polymers having various repeat units containing one or more ester moieties. The corrosion inhibitors can be imidazoline compounds, quaternary ammonium compounds, or a combination thereof. These solid compositions can be used to treat subterranean hydrocarbon-containing reservoir and can inhibit or reduce paraffin deposition in the reservoir and/or inhibit or reduce corrosion in a piece of equipment in contact with the reservoir.

Solid paraffin inhibitor and corrosion inhibitor compositions

Disclosed herein are the methods of using di-cationic or di-anionic compounds, which are derived from primary amine through an aza-Michael addition with an activated olefin, in a corrosion control composition to mitigate corrosion of a surface in a water system. The disclosed methods or compositions are found to be more effective than those methods or compositions including commonly used single quaternary compounds for mitigating corrosion for a metal surface in water systems.

Use of di-ionic compounds as corrosion inhibitors in a water system

Disclosed are succinimide-based compounds used in compositions and methods for inhibiting natural gas hydrate agglomerates. The succinimide-based compounds are reaction products of an alkenyl succinic anhydride and an amine or amine alcohol.

Alkenyl succinimides and use as natural gas hydrate inhibitors

The present invention generally relates to compositions and methods for inhibiting corrosion at a surface in the production, transportation, storage, and separation of crude oil and natural gas.

Thiol-formyl hemiacetal corrosion inhibitors

Disclosed are methods for preparing disulfide compounds through oxidative coupling of thiol compounds. Thiols are oxidized to the corresponding disulfide compound in high yield in presence of a base and a metal salt. The method uses low catalyst loadings and provides organic disulfide compounds with little to no byproducts.

Metal-catalyzed oxidative coupling of thiols

Disclosed are corrosion inhibitor compounds and compositions useful in applications relating to the production, transportation, storage, and separation of crude oil and natural gas. Also disclosed 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.
