Abstract:
A cleanup fluid for reducing a viscosity of a residual viscous material in fractures of a hydrocarbon-bearing formation. The cleanup fluid includes an exothermic reaction component operable to generate heat, where the heat is operable to reduce a viscosity of the residual viscous material to create a reduced viscosity material, the reduced viscosity material operable to flow from the fractures.

Claim (Index 1):
A method for use of a cleanup fluid in a wellbore or reservoir, the method comprising the steps of:\n preparing an exothermic reaction component operable to generate heat, and the exothermic reaction component comprising at least one component selected from the group consisting of: urea; sodium hypochlorite; ammonium chloride; ammonium bromide; ammonium nitrate; ammonium sulfate; ammonium carbonate; ammonium hydroxide; sodium nitrite; potassium nitrite; and mixtures thereof,\n where the cleanup fluid comprises only liquid components in solution prepared to be fluidly compatible with a viscous fluid component such that the cleanup fluid and viscous fluid component quickly mix, \n where the cleanup fluid does not include viscosifying components at concentrations that generate foam or introduce foam into the wellbore; \n injecting the exothermic reaction component into the wellbore; and allowing the exothermic reaction component to react in situ to produce heat and nitrogen gas, the heat and nitrogen gas operable to increase temperature and pressure in situ, to create a reduced viscosity material.
