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: A method of non-mechanically remediating damage to a wellbore comprising a plurality of fracture stages is disclosed. A total treatment volume is calculated based on the plurality of fracture stages, the wellbore space, and either the production tubing or the annulus of the wellbore. The fracture stages of the wellbore are then divided into a plurality of chemical stages. The wellbore is pre-flushed, and each chemical stage is treated and isolated in order of depth by a volume of remediation chemical and volume of diverter. A post-treatment flush completes the remediation process and after a shut-in period, the well's production is substantially improved.
