Lumpkin, W B; Meldau, R F

A method and apparatus analyzes a gas stream from an underground in situ combustion process to provide one or more parameters for indicating the conditions in the combustion zone and facilitating control of the combustion operation. In one aspect of the method, the signal from various instruments are rationalized through a control computer. This puts out a control signal and/or a print out for use in controlling the air injection rate and/or the production rate at the production well head to maintain an optimum utilization of the oxygen in the air stream and to optimize the in situ cracking process.
