Abstract

See full text

Process and apparatus are set forth for ascertaining and controlling the flammability of produced gas from an in-situ combustion enhanced petroleum production well whereby the produced oil is sampled, the produced gas is periodically sampled, the temperature, pressure and produced gas flow rate are sensed, and a moderant gas is added to the production well to avoid flammability when the sampled and sensed parameters indicate a flammability condition exists.
