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 disposed in a 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, \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; 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; and injecting an oxidizer into the wellbore as a breaker after the step of injecting the exothermic reaction component into the wellbore, where the oxidizer comprises at least one compound selected from the group consisting of: tertiary amines; organic esters; and transition metal salts.
