Methods and compositions for altering the viscosity of treatment fluids used in subterranean operations |
| abstract |
Methods of decreasing the viscosity of a treatment fluid through contact with a cyclodextrin modifier. Such methods include providing a cyclodextrin modifier; providing a treatment fluid that comprises a base fluid and a viscosifying agent wherein the viscosifying agent is selected from the group consisting of a hydrophobically modified polymer, a viscoelastic surfactant, a phosphonate surfactant, or a combination thereof; and, 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. |
