Compositions and a process for consolidating sand, proppant and other suspended particles present in a subterranean reservoir using an aqueous emulsion particle consolidation system. Surfactants with cloud points 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 release the resin and curing agent to consolidate the sand. The aqueous phase of the system then functions as spacer to maintain the permeability needed for oil and gas production without additional post flush needed.

A method of controlling fines migration in a wellbore penetrating a subterranean formation, the method comprising: introducing into the wellbore a screen mesh in an unexpanded form disposed of a first tubular member having a body with apertures, the screen mesh comprising a degradable material; expanding the screen mesh; injecting a cement slurry into the wellbore to fill open spaces within the expanded screen mesh; allowing the cement slurry to set forming a set cement that reduces or substantially preventing the passage of formation particles from migrating from the subterranean formation into the wellbore; and removing the degradable material of the screen mesh forming a fluid pathway in the set cement, which allows a formation fluid to flow from the subterranean formation into the wellbore.

A method of treating particles of a particle pack located in a subterranean formation comprising: introducing the foam into the subterranean formation; and consolidating the particles of the particle pack after introduction into the subterranean formation.

A method of treating a subterranean formation penetrated by a wellbore comprises: introducing into the subterranean formation a treatment fluid comprising coated polymeric particles having a polymeric core and a curable thermoset coating disposed on the polymeric core; allowing the curable thermoset coating to cure under downhole conditions; and forming a fluid-permeable pack from the coated polymeric particles, the fluid-permeable pack reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore.
