A catalyst containing steam generator is lowered to the formation to be steamed. A packer is set at the upper extension of the generator to retain the steam. Fuel gas and oxidizing gas are passed through the catalyst which causes combustion within the catalyst bed. Water is passed over the heated tube retaining the hot catalyst bed or through the catalyst bed to produce steam.
