1. A method of recovering heavy oil from a subterranean heavy oil reservoir, the method comprising:
conducting an exothermic chemical reaction of a feedstock chemical to produce a reaction product that is a first solvent; injecting an injected solvent comprising the reaction product into the subterranean heavy oil reservoir, wherein said injected solvent has an injected solvent temperature equal to an elevated temperature resulting from heat generated by said exothermic chemical reaction, the elevated temperature being greater than an ambient reservoir temperature, and wherein injecting occurs before said injected solvent temperature has decreased to said ambient reservoir temperature. |
