Abstract
A method of recovering heavy oil from a subterranean heavy oil reservoir. The method includes conducting an exothermic chemical reaction of feedstock chemicals to produce a reaction product that that is a first solvent and injecting an injected solvent including the reaction product into the subterranean heavy oil reservoir. The injected solvent has an injected solvent temperature equal to an elevated temperature resulting from heat generated by the at least one exothermic chemical reaction and the injecting occurs before the injected solvent temperature has decreased to an ambient reservoir temperature.

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.
