ABSTRACT:
A recovery process and system wherein hydrogen and oxygen are introduced into a vented pressure vessel, known as a gas generator, located at the bottom of a borehole, and ignited and burned to produce steam. The hydrogen and oxygen may be introduced either as a stoichiometric mixture or the combustible mixture may be hydrogen-rich. Remotely controlled valves are located downhole near the gas generator for positive control of the hydrogen and oxygen. Provision is made for maintaining the desired hydrogen-oxygen ratio either by a hydrogen flow control slaved to a downhole thermocouple or by a special hydrogen-oxygen flow control employed in the event that ignition is carried out by a DC power supply located downhole. Although the preferred embodiment employs a fuel-oxidizer combination of hydrogen and oxygen, provision is made for employing other fuel-oxidizer combinations.
