摘要： Methods are provided for treating a portion of a well and include the steps of: (a) forming a treatment fluid comprising an aqueous solution, wherein the aqueous solution comprises: (i) water; (ii) a water-soluble polysaccharide; (iii) one or more water-soluble salts, wherein the one or more salts are selected and are in at least a sufficient concentration such that the water-salt solution has a density of at least 10 ppg; and (iv) urea; and (b) introducing the treatment fluid into the portion of the well. According to the inventions, the concentration of the urea in the water is in at least a sufficient concentration such that aqueous solution: (1) has a G′ of at least 2 Pa, or (2) is filterable. According to the inventions, an identical aqueous solution except with less than the sufficient concentration of the urea would not satisfy the above conditions.

摘要： Well bore servicing fluids are provided that include a thermally activated viscosification compound. Further, methods of servicing a well bore are provided that include displacing such a servicing fluid into the well bore, wherein a viscosity of the servicing fluid increases as it passes down the well bore due to its temperature increasing. Thus, the viscosity of the servicing fluid is effective to suspend solids therein when the servicing fluid is in the well bore. The servicing fluid may be, for example, a cement slurry, a drilling fluid, a gravel packing fluid, a fracturing fluid, a completion fluid, or a work-over fluid. In an embodiment, the thermally activated viscosification compound includes at least one water-soluble hydrophobically modified polymer comprising a hydrophobic substituent having from about 1 to about 22 carbon atoms.
