System and method of producing oil

A system for producing oil from an oil reservoir having a well, the system comprising:

• a system casing;
• a combustor arranged within the system casing and configured to combust a fuel during operation;
• a diluent generator having a first end fluidly coupled to receive combustion gases from the combustor, the diluent generator further having a second end fluidly coupled to the oil reservoir;
• a diluent conduit fluidly arranged between the inner surface of the system casing and an outside surface of the combustor and the diluent generator, the diluent conduit extending along the length of the combustor and diluent generator;
• and
• a plurality of nozzles coupled to the outside surface of the diluent generator and configured during operation to spray a diluent fluid into the combustion gases in the diluent generator, a direction of spray being at least partially towards the first end, the plurality of nozzles being offset both longitudinally and circumferentially about the housing.

A system for producing oil from an oil reservoir having a well, the system comprising:

• a system casing;
• a fuel conduit and an oxidant conduit movably arranged within the system casing;
• a mixer arranged within the system casing and configured to receive an oxidant and a fuel from the fuel conduit and the oxidant conduit,
• a combustor portion disposed within the system casing and operably coupled to and spaced apart from an end of the mixer and configured to form combustion gases;
• a diluent generator portion disposed within the system casing and operably coupled to the combustor portion opposite the mixer, the diluent generator portion having a terminal end coupled to the system casing;
• a diluent conduit extending along the length of and thermally coupled to the combustor and diluent generator;
• a plurality of nozzles coupled to the diluent generator and fluidly coupled to the diluent conduit, the at least one nozzle being positioned to spray a diluent fluid from the diluent conduit in a direction towards the combustor portion, the plurality of nozzles being offset both longitudinally and circumferentially about the diluent;
• and
• at least one centering member slidably engaging an inside surface of the system casing and is operably coupled the mixer, the combustor portion and the diluent generator portion.
