ABSTRACT:
A method for generating a heated product stream downhole is provided wherein a fuel rich mixture is reacted downhole by contact with a catalyst to produce a partially reacted product stream, the fuel rich mixture comprising fuel and oxygen. The partially reacted product stream is brought into contact with an oxidant thereby igniting combustion upon contact producing a combustion product stream. The combustion product stream may be cooled by injecting a diluent flow such as water or CO2. The cooled combustion product stream may be into an oil bearing strata in order to reduce the energy requirements for the production of heavy oil.
