This paper explains the idea behind the tertiary recovery method of heavy crude oil from a reservoir using the thermal recovery method of fire flooding (in situ combustion) and its processes of incorporating conditions of the crude. These heavy oils have high viscosity which requires more heat to and create less surface tension in order to allow for much better mobility. In order for this all to happen and it relies on the use of injected air and water while also utilizing those components to the advantage of thermal recovery to heat and vaporize oil and produce steam from water. This heated gas and vapor then provides a thermal push by combustion and pushing oil into the designated production well by methods of dry combustion (air injection, no water), wet combustion (air injection with water), and reverse combustion by means of injecting water and gas on opposite sides of the reservoir for the complete combustion of the whole reservoir.

Tertiary Thermal Recovery by Fire Flooding
Thermal Recovery is used as a tertiary means of getting oil out of some reservoirs that are so highly viscous that the fluid is unable to flow out of the reservoir and into the well (Denehy, 2011). It contains its own form of properties similar to solid materials that can, nonetheless, be pushed to flow with the addition of heat as a means of lowering the viscosity of…
