ABSTRACT:
The invention provides a composition for use in a subterranean formation penetrated by a wellbore, the composition comprising: a) a solvent consisting essentially of a water-soluble solvent selected from the group consisting of any solvent that is at least 25% by weight soluble in water and any mixture of two or more thereof in any proportion, wherein the solvent is from about 90% to about 99.9% by weight of the composition; and b) a tackifying compound, wherein the tackifying compound is from about 0.01% to about 10% by weight of the composition; wherein the tackifying compound and the solvent are mutually selected such that, for the ratio of the tackifying compound to the solvent, the tackifying compound is soluble in the solvent. The invention also provides a method for treating a subterranean formation penetrated by a wellbore, the method comprising the steps of: a) forming the composition; and b) introducing the composition through the wellbore into the subterranean formation. Preferably, the solvent consists essentially of isopropyl alcohol.
