  • Corrosion inhibitor systems for low, moderate and high temperature fluids and methods for making and using same
    Patent number: 9234125
    Abstract: A corrosion control system is disclosed including an anionic oxygen inhibitor, a cationic acid inhibitor or dispersant, and a noxious species inhibitor or scavenger for use in a fluid in contact with a metallic surface at low temperature, moderate temperature and especially at high temperature. A drilling fluid, a completion fluid, a production fluid and a geothermal fluid including an effective amount of the corrosion control system is also disclosed as well as methods for making and using same.
    Type: Grant
    Filed: October 21, 2013
    Date of Patent: January 12, 2016
    Inventors: Larry W. Gatlin, Khalid Ali Shah

  • CORROSION INHIBITOR FOR HIGH TEMPERATURE ENVIRONMENTS
    Publication number: 20130175477
    Abstract: Corrosion inhibiting and management systems and for methods of making and using same are presented, where the corrosion systems comprise a reaction product or mixture of reaction products of medium to high carbon count phosphate ester or mixture of medium to a high carbon count phosphate esters and an amine or mixture of amines and where the reaction product or products form a partial or complete coating on surfaces of pipe, piping, pipeline, flowline, and other downhole equipment in contact with aqueous and non-aqueous fluids to protect the surfaces from corrosion at temperature up to up to 750° F. (398.9° C.), and especially, for use in applications using low to moderate temperature geothermal fluids.
