Abstract: Various embodiments of the present technology generally relate to systems and methods for inhibiting corrosion to metal infrastructure within upstream oilfield systems. In an example, a method for inhibiting corrosion of metal infrastructure within a wellbore includes providing a corrosion-inhibiting agent and dissolving the corrosion-inhibiting agent in a solvent to form a corrosion-inhibiting solution. In various aspects, the corrosion-inhibiting agent may be organic and/or sulfur-free. The corrosion-inhibiting solution may be injected into a wellbore where the corrosion-inhibiting solution reduces an oxygen concentration within the wellbore to below 1 parts-per-million (ppm) and achieves a corrosion rate of equal to or less than 0.02 lb/ft2.

Abstract: Disclosed herein are extended- and multimodal-release compositions for inhibiting scale in an industrial water system. In an example, an extended-release composition for inhibiting scale in an industrial water system includes a solid, particulate scale inhibitor. The solid, particular scale inhibitor may include a phosphonate, a carboxylate, or a combination thereof; and a divalent cation, a trivalent cation, or a combination thereof.

Abstract: A novel method for a controlled release of oil well treating compositions is revealed. The “engineered composite” are formed by mixing well treatment agents with an impervious substrate that exhibit low solubility in water and oil. The engineered composite is introduced in to subterranean wells along with a carrier, fluid to release well, treatment agents over extended periods of time.
