abbr: combination of forward combustion and water flooding. Also called wet combustion.

a tertiary recovery mechanist consisting of combustion and water flooding.

n: a common type of in situ combustion in which the combustion front moves in the same direction as the injected air. Burning is started at an injection well and moves toward production wells as air is continuously injected into the injection well. Compare reverse combustion.

n: a type of in situ combustion in which the combustion front moves counter to the direction of the injected air. Air is injected into a production well and burning is started near the well. When the combustion zone has advanced a short distance from the well. air injection is stopped from the production well and started from an adjacent injection well. The fire advances toward the injection well, but the oil moves toward the production well. This method may be used with very viscous oils. Compare forward combustion.

n: the simultaneous or alternate injection of water and air into a formation during an in situ combustion operation. The water reduces heat loss by transmitting heat that would otherwise be left behind in the formation, reduces the amount of required air, and increases the rate of advance of the fire flood. Also called COFCAW (combination of forward combustion and waterflooding). Compare dry combustion.

injecting air and water into a reservoir during a fireflood.
