Patent ID: 8877691

Claim:
A method comprising: providing a cyclodextrin modifier comprising hydroxypropyl-β-cyclodextrin; providing a treatment fluid that comprises a base fluid and a viscosifying agent; wherein the viscosifying agent comprises a hydrophobically modified polymer and the viscosifying agent optionally further comprises, a viscoelastic surfactant, a phosphonate surfactant, or a combination thereof; and, wherein the hydrophobically modified polymer comprises hydroxyethyl cellulose introducing the cyclodextrin modifier and the treatment fluid into a well bore penetrating a subterranean formation wherein the viscosity of the treatment fluid is decreased due to the combination of the hydrophobically modified polymer and the cyclodextrin modifier, wherein the cyclodextrin modifier is present in an amount of about 1% to about 20% by weight of the treatment fluid; and wherein the viscosifying agent is present in amount of about 0.1% to about 10% by weight of the treatment fluid.
