Abstract
A combination corrosion/scale inhibitor composition for use in oil or gas wells is provided which is in the form of a substantially homogeneous dispersion so as to facilitate use and well coverage of the composition, and to minimize well downtime. The overall composition preferably includes a preblend having an imidazoline-based corrosion inhibitor and an organophosphonic scale inhibitor, together with an organic solvent and an alkylphenol ethoxylate surfactant; the preblend is then field-mixed with water or crude oil to yield a final treating composition. In practice the final composition may be introduced into the well in bulk or over time so as to achieve full coverage of down-hole equipment with both the corrosion and scale inhibitor.
