1. A tool for expediting the downhole sampling of hydrocarbons of a formation traversed by a borehole, the tool comprising:

  • a first chamber carrying a first reactant;

    a second chamber separate from said first chamber and carrying a second reactant, said first reactant and second reactant chosen to generate an exothermic chemical reaction when in contact with each other;

    a first port coupled to said first chamber and said second chamber; and

    an injector coupled to said first port, said injector injecting heated injection fluid generated by causing said first reactant and said second reactant to react in an exothermic chemical reaction while in said tool through said first port and into one of the borehole or the formation.
