Abstract: A stamped bare wire metal heating element for heating fluid in a tankless electric fluid heating device may include a first electrically conductive portion extending linearly; a second electrically conductive portion extending linearly; and a third electrically conductive portion connecting the first electrically conductive portion to the second electrically conductive portion at a first end of the stamped bare wire metal heating element, wherein the stamped bare wire metal heating element is open between the first electrically conductive portion and the second electrically conductive portion at a second end of the stamped bare wire metal heating element.

Abstract: Disclosed herein is a novel class of multiple charged cationic or anionic compounds that are derived from an aza-Michael Addition reaction between a polyamine (Michael donor) and an activated olefin (Michael acceptor), methods of making the same, and use thereof. Also disclosed herein are the methods of using multiple charged cationic or anionic compounds disclosed herein in a reverse emulsion breaker composition to break reverse emulsion commonly found in a produced fluid in oil and gas operations. The disclosed REB methods or compositions are found to be more effective than those methods or compositions including commonly used for oil/solid and water separation.

Abstract: Multiple charged cationic compounds, which are derived from polyamines through an aza-Michael addition with an ?, ?-unsaturated carbonyl compound, in a clay treatment composition to reduces clay swelling, clay migration, and sludge formation in a subterranean formation in oil and gas operations are provided. The disclosed methods or compositions are found to be more effective than those methods or compositions commonly used for reducing clay swelling, clay migration, and sludge formation.

Abstract: Corrosion inhibitor compositions, methods of inhibiting or reducing corrosion, and methods of manufacturing corrosion inhibitor compositions are disclosed herein. In certain methods, the corrosion inhibitor compositions may be added to an aqueous industrial system having at least one surface. The aqueous industrial system may be a water recirculating system, a cooling water system, a boiler water system, a pulp slurry, a papermaking process, a ceramic slurry, a mixed solid/liquid system, or an oil-field system. A method of manufacturing a corrosion inhibitor composition may include reacting an alkanolamine with a fatty acid to form a fatty acid ester reaction product and reacting the fatty acid ester reaction product with an alkyl halide or an acrylate.

Abstract: 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.
