Improved corrosion inhibitors for well brines include a phosphonate or salts thereof, and a gluconic acid or salts thereof. The inhibitors are normally injected downhole into the brines. The most preferred phosphonates are amine polyphosphonates, used in combination with alkali metal salts of gluconic acid.

Improved emulsion breakers in the form of polyol acrylate polymers in water/oil emulsions have relatively high polymer contents and low inversion viscosities. The emulsion breakers can be prepared by mixing together acrylate monomer, polyol, water, liquid petroleum product, and emulsifier, followed by homogenization of the mixture; the latter is then subjected to free radical polymerization to polymerize the polyol and monomer in situ within the mixture.

Poly alkanolamines formed as the reaction products of secondary or tertiary alkanolamines, C8-C24 fatty acids, and shorter chain organic acids are provided, which serve as excellent petroleum/water emulsion breakers for water-in-oil emulsions and reverse oil-in-water emulsions. The polymers are preferably prepared using a reaction mixture of triethanolamine, tall oil fatty acids, and acetic acid.

Methods of synthesizing polymers including repeat units of the formula comprise the step of polymerizing repeat units of the formula in the presence of a free radical catalyst, where each R and each M is separately and independently selected from the group consisting of H, C1-C12 straight or branched chain alkyl, aryl, amine, amide, and ester groups, halides, and mixtures thereof, and n ranges from about 2-15.
