1. A method of recovering hydrocarbons from a hydrocarbon formation containing hydrocarbon reserves, at least one injection well and one production well, the process comprising the steps of:
a. injecting a chemical composition into the hydrocarbon formation in an amount effective to, when added to the formation, substantially increase the recovery of hydrocarbons from the reserves,
wherein the chemical composition comprises a primary (methyl, ethyl or benzyl) amine compound, an alcohol and an aqueous carrier solution;
said alcohol being selected from the group of butyl alcohol and phenol alcohol; and
said aqueous carrier solution is a 50% to 75% aqueous solution having a divalent hardness contamination less than 50 ppm;
b. heating said aqueous carrier solution in an annular flow across a tubular encapsulated Polonium thermal battery, said Polonium therermal battery having a first stabilize surface temperature between 300 F and 400 F;
wherein said heating step transfers enough heat from said Polonium thermal battery to said aqueous carrier solution to make a 30 to 75 quality steam phase in said aqueous carrier solution;
c. injecting said 30 to 75 quality steam phase aqueous carrier solution into the hydrocarbon formation containing the hydrocarbon reserves; and
d. thereby producing hydrocarbons and aqueous carrier solution within at least one production well to recover the hydrocarbons from the formation.
