A method for treating a zone of a well with a viscosified fluid is provided, wherein the fluid is adapted to break in the well. The method includes the steps of: (A) introducing a well fluid into the zone of the well, wherein the well fluid includes: (i) a water phase; (ii) a water-soluble polymer in the water-phase; and (iii) a source of a hydroxylamine or salt thereof; and (B) allowing the viscosity of the well fluid to break in the zone. |
