A method of inhibiting carbon dioxide (CO) hydrate formation in a COpipeline is described. The method includes injecting a composition including monoethylene glycol carbon quantum dots (MEG CQDs) into the COpipeline to deposit the MEG CQDs on an inside surface of the COpipeline. The method further includes pressurizing the COpipeline with a gas stream containing COand 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 COpipeline in an amount effective to reduce the formation of COhydrates in the COpipeline during the pressurizing in comparison to the formation of the COhydrates in the COpipeline under the same conditions but in the absence of the MEG CQDs.

Method of inhibiting carbon dioxide hydrate formation

A silane-modified colloidal silica in the form of a Pickering emulsion and a method for enhancing recovery of hydrocarbons and improving conformance using it. When injected into an oil well, the silane-modified colloidal silica separates into an aqueous phase and oil/oleic phase. The aqueous phase forms a gel that blocks the flow of water and the oleic phase that forms permits oil to flow out of the well.
