Patent number: 11697761Abstract: Graphene quantum dots are functionalized by covalently bonding a corrosion inhibitor molecule thereto. In a useful method, a corrosion inhibitor compound is blended with a graphene quantum dot-tagged corrosion inhibitor compound, and the blend is applied to a metal surface, such as the interior of a carbon steel pipe. The blend inhibits corrosion arising from contact with produced water generated by hydrocarbon recovery from one or more subterranean reservoirs. The produced water having the blend dispersed therein is irradiated with a source of light having a selected first range of wavelengths, and the luminescent emission of the graphene quantum dot-tagged corrosion inhibitor is measured at a selected second range of wavelengths, thereby providing for real-time measurement of corrosion inhibitor concentration within the pipe.Type: GrantFiled: February 4, 2021Date of Patent: July 11, 2023Assignee: ChampionX USA Inc.Inventors: Jeremy Moloney, Kousik Kundu

Patent number: 11697604Abstract: Disclosed herein are graphene quantum dot tagged water source treatment compounds or polymers, and methods of making and using. Also described herein are tagged compositions including an industrial water source treatment compound or polymer combined with a graphene quantum dot tagged water source treatment compound or polymer. The tagged materials are tailored to fluoresce at wavelengths with minimized correspondence to the natural or “background” fluorescence of irradiated materials in industrial water sources, enabling quantification of the concentration of the water source treatment compound or polymer in situ by irradiation and fluorescence measurement of the water source containing the tagged water source treatment compound or polymer. The fluorescence measurement methods are similarly useful to quantify mixtures of tagged and untagged water source treatment compounds or polymers present in an industrial water source.Type: GrantFiled: September 24, 2021Date of Patent: July 11, 2023Assignee: ChampionX USA Inc.Inventors: Jeremy Moloney, Kousik Kundu
