    Abstract: A thermoviscoelastic system (TVE) fluid useful in a well treatment method can include a hydrophobically-modified polymer and a viscoelastic surfactant (VES) in an aqueous medium, wherein the polymer has a lower critical solution temperature (LCST). The polymer can have water solubility for preparation below the LCST, and the TVE has a low viscosity for pumping down a well bore in communication with a subterranean formation. When the TVE is heated above the LCST, interaction between the hydrophobic groups of the polymer and the VES form a cross-linked network to increase the viscosity to transport proppant into a fracture. The thickened TVE can have a low leak-off rate, optionally including colloidal particles or other fluid loss control agent, and can be broken by contact with hydrocarbons as during flowback from the reservoir.

    Abstract: In a method of treating a sandstone-containing subterranean formation penetrated by a wellbore, a slurry of a carrier fluid containing a surface modification agent of at least one of a hydrolyzable organosilicon compound, a phosphonate compound or a combination of these is formed. The slurry is introduced into the wellbore at or above the fracture pressure of the formation. A sandstone-dissolving material is introduced into the wellbore with or subsequent to introduction of the slurry. The surface modification agent may be encapsulated within an encapsulating material. A composition for use in treating sandstone-containing subterranean formations is also provided. The composition includes an aqueous carrier fluid containing an encapsulated surface modification agent of at least one of a hydrolysable organosilicon compound and a phosphonate compound that is encapsulated within an encapsulating material.
