  • METHOD OF OIL RECOVERY USING COMPOSITIONS OF CARBON DIOXIDE AND COMPOUNDS TO INCREASE WATER WETTABILITY OF FORMATIONS
    Publication number: 20250250479
    Abstract: A method of recovering hydrocarbons from a subterranean formation includes injecting into the subterranean formation a composition including carbon dioxide and at least one carbon-dioxide-soluble compound under conditions favorable to diffusion into and adsorption of the carbon-dioxide-soluble compound on the subterranean formation so that oil-wettability is decreased or water wettability or CO2-philicity is increased in at least a portion the subterranean formation.
    Type: Application
    Filed: April 28, 2025
    Publication date: August 7, 2025
    Inventors: Robert M. Enick, Deepak Tapriyal, Angela Goodman Hanson, Dustin Crandall
