Patent number: 11807789Abstract: A method of inhibiting carbon dioxide (CO2) hydrate formation in a CO2 pipeline is described. The method includes injecting a composition including monoethylene glycol carbon quantum dots (MEG CQDs) into the CO2 pipeline to deposit the MEG CQDs on an inside surface of the CO2 pipeline. The method further includes pressurizing the CO2 pipeline with a gas stream containing CO2 and water vapor at a pressure of 200-2,000 pounds per square inch (psi). The MEG CQDs are present on the inside surface of the CO2 pipeline in an amount effective to reduce the formation of CO2 hydrates in the CO2 pipeline during the pressurizing in comparison to the formation of the CO2 hydrates in the CO2 pipeline under the same conditions but in the absence of the MEG CQDs.Type: GrantFiled: March 25, 2022Date of Patent: November 7, 2023Assignee: King Fahd University of Petroleum and MineralsInventors: Abdullah S.

Patent number: 9920238Abstract: A process for recovering oil from a carbonate reservoir of high salinity, wherein supercritical CO2 floodings are combined with a fluorosurfactant in the tertiary recovery. Embodiments include alternating injection and co-injection schemes of the supercritical CO2 and the fluorosurfactant. A stable fluorosurfactant-CO2 foam that is not susceptible to the harsh conditions of the reservoir (temperature, pressure and salinity) can be successfully generated, leading to a reduction in the mobility of CO2, an increase in the mobility of the reservoir oil, higher contact between the injected fluid with the oil and a better sweep efficiency of the oil.Type: GrantFiled: April 21, 2017Date of Patent: March 20, 2018Assignee: King Fahd University of Petroleum and MineralsInventors: Zaid Zaffar Jangda, Abdullah S.
