recovery methods for heavy oil reservoirs
dear all,
I need to know what the most applicable methods are in the recovery of heavy oil reservoirs

In situ combustion technique involves heat generation within reservoir itself. Air is injected and burns some of oil and cause displacement of remaining oil. Water is often injected which transfer heat from combustion zone to the other zones of reservoir so by combination of steam, hot water and combustion gas oil become less viscous and start flowing towards production well. There are different types of In situ combustion methods:
In Situ dry combustion (forward or reverse)
In situ wet combustion: This process permits the injected water to scavenge heat left behind the burning front, where the water flashes to steam and moves through the burning front to enlarge the advancing steam zone.
In situ combustion with oxygen: This process involves injection with air or oxygen, either in alternating slugs or as continuous injection which increases the efficiency.
