Abstract
Embodiments described herein provide corrosion inhibitors that use hyperbranched polymer molecules functionalized with amino carboxylic acids, epoxides, and/or long chain fatty acids, or combinations thereof. Nitrogen atoms in such molecules can be quaternized to increase water solubility if needed. Such hyperbranched polymer corrosion inhibitors can be used in all stages of oil and gas operation.
