|20120283147||LOW DOSAGE POLYMERIC NAPHTHENATE INHIBITORS - Polymeric naphthenate inhibitors are delivered into production fluids to contact mixtures of oil and water, such as in a hydrocarbon producing formation, production equipment, or processing systems. These polymeric naphthenate inhibitors exhibit surface-active properties causing the inhibitors to self-associate at oil-water interfaces and inhibit interactions between organic acids in the oil and cations or cation complexes in water. The large surface area makes these polymers persistent and effective at low concentrations. These compounds also inhibit aggregation of organic acid carboxylate salts that form when pH and pressure conditions are amenable to organic acid ionization. Preferred inhibitors do not form emulsions due to the formation of unstable mixed interface structures that result in coalescence of dispersed droplets. Naphthenate inhibitor dosages less than 100 ppm can effectively inhibit naphthenate salts or other organic acid salts that can form precipitates or emulsions during crude oil production or processing.||11-08-2012|

Nonionic dispersion polymers consistently render substantially greater extents of friction reduction than their ionic counterparts. A dispersion polymer (formed by dispersion polymerization) provides up to four times as much friction reduction as the same polymer in solution when used at the same dosage. Moreover, unlike ionic dispersion polymers, nonionic dispersion polymers are intrinsically compatible with charged oilfield species such as multi-valence brine(s), quaternary amine-based corrosion inhibitors and biocides.||12-23-2010|
|20100163494||PREPARATION OF ENVIRONMENTALLY ACCEPTABLE SCALE INHIBITORS - Alkyl phosphonates prepared from amino acids suitable for use in inhibiting scale. The phosphonates are obtained as reaction mixtures where the level of alkyl phosphonation is deliberately controlled to provide only partial alkyl phosphonation of the amino acid.

The compositions possess advantages over existing phosphonates in that they exhibit higher biodegradation by method OECD 306. They also offer lower toxicity to marine life compared to the fully substituted species and are not expected to bioaccumulate.||07-01-2010|
