Gellable treatment fluids containing a terpolymer that comprises 2-acrylamido-2-methylpropanesulfonic acid, acrylamide, acrylic acid monomer units can be used in various subterranean operations where it is necessary for the treatment fluid to remain in a gelled state for extended periods of time at high formation temperatures. Methods for treating a subterranean formation can comprise providing a treatment fluid comprising an aqueous carrier fluid, a crosslinking agent, a gel stabilizer, and a terpolymer that comprises 2-acrylamido-2-methylpropanesulfonic acid, acrylamide, and acrylic acid monomer units, or any salt thereof; introducing the treatment fluid into a subterranean formation; allowing the treatment fluid to form a gel in the subterranean formation; and breaking the gel after it has been in the subterranean formation for at least about one day.

Well completion methods using gellable treatment fluids having long term thermal stability of the gelled state

A method of servicing a wellbore comprising placing a composition comprising an emulsified resin composite into a fluid loss zone of the wellbore, wherein the emulsified resin composite comprises a nonaqueous external phase (NEP) and an aqueous internal phase (AIP), and allowing the composition to cure to form a composite material.

Composite formulations and methods of making and using same

An improved refrigerant composition, or a kit for an improved refrigerant composition, for use in air conditioners comprising a refrigerant, wherein the refrigerant comprises a hydrofluorocarbon having a GWP of less than about 10 and an ODP of about zero, which is present at a concentration of at least about 50% by weight of the refrigerant composition; a lubricant wherein the lubricant is a polar, oxygenated lubricant; and an acid scavenger comprising a siloxane, an activated aromatic compound, or any mixtures thereof.
