In-depth insights into the in-situ combustion characteristics of heavy oil: Temperature, oil-gas-water saturation, coke deposition, and enhanced oil recovery

Puntos clave

• In-situ combustion improves enhanced oil recovery efficiency, leading to better yield.
• Key evidence indicates that higher temperatures result in significant oil-gas-water saturation changes, impacting recovery.
• Analysis of combustion characteristics provides insights into coke deposition and its effects on heavy oil extraction.
• Enhanced oil recovery techniques may benefit from understanding the interplay of temperature and saturation levels.
