A catalytic combustor for generating a mixture of steam and combustion gas is located downhole in an oil well, so that the gas mixture can be injected directly into the oil reservoir to displace heavy oils from the reservoir. There can be a single stage of catalytic combustion, or there can be a stage of thermal combustion followed by a catalytic stage. In either case the purpose of the catalyst is to drive the combustion to completion so that the gas mixture contains no soot that would plug the face of the reservoir.
