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.

Patent number: 11781058Abstract: A process for consolidating sand, proppant and other suspended particles present in a subterranean reservoir using an aqueous emulsion particle consolidation system is described. Surfactants with cloud points at or below the reservoir temperature are used to make a low viscosity aqueous external emulsion system with resin and curing agent as the internal phase. As the surfactant reaches its cloud point, it loses its emulsification ability and releases the resin and curing agent to consolidate the sand. The aqueous phase of the system then functions as a spacer to maintain the permeability needed for oil and gas production without additional post flush required.Type: GrantFiled: September 1, 2022Date of Patent: October 10, 2023Assignee: OIL CHEM TECHNOLOGIESInventors: Paul Daniel Berger, Christie Huimin Berger
