Abstract
Compositions for treating a wellbore include an exothermic additive capable of initiating an exothermic event following contact with a carrier fluid. The exothermic additive can have a coating that delays the exothermic event after contact with the carrier fluid. Methods disclosed herein include emplacing a fluid loss treatment composition in an interval of a wellbore, the fluid loss treatment including: a metallic fluid loss additive; an exothermic additive; and a carrier fluid; and reacting the exothermic additive to initiate an increase in temperature in the interval of the wellbore above a melting point of the metallic fluid loss additive; and converting the metallic fluid loss additive to a molten fluid loss additive; and treating the interval of the wellbore with the molten fluid loss additive.
