Abstract: Corrosion inhibitors and methods for inhibiting or reducing corrosion of metallic surfaces are provided. A corrosion inhibitor composition may include a 3-alkylamino-2-hydroxysuccinic acid compound. A method of inhibiting corrosion of a metallic surface in an aqueous system includes the step of contacting the surface with an effective amount of a corrosion inhibitor composition. The corrosion inhibitor composition may include other components, such as zinc, and it may also exclude phosphorus.

Abstract: Emulsions of mobility control polymers can be used to increase recovery of crude oil from a subterranean hydrocarbon-containing formation. A flooding fluid comprising the polymer emulsions are injected into a well that is in contact with the subterranean hydrocarbon-containing formation. The polymers can be temporarily cross-linked and have protected shear degradation and improved injectivity into the well; the shear resistance can be measured in terms of viscosity loss due to shear, and the improved injectivity can be measured in terms of the flooding fluid's filter ratio, flow rate, and viscosity.

Abstract: Corrosion inhibitors and methods for reducing or inhibiting corrosion of metals in aqueous systems are provided. Corrosion inhibitor compositions may include tetracarboxylic acids, such as butane tetracarboxylic acid. The compositions may include other components, such as zinc, molybdate, silicate, cerium, among others. The compositions may also include polymers or oligomers. The corrosion inhibitor compositions produced synergistic results and unexpectedly low corrosion rates.
