Thermal EOR ProcessLimitations :•Steam flooded reservoirs should be as shallow as possibleas long as pressure for sufficient injection rates can bemaintained. This is to avoid excessive heat losses in thewell bore.•Steam flooding is not normally used in carbonate reservoir.•Cost per incremental barrel of oil is high.•Low percentage of water-sensitive clays is desired forgood injectivity.•Adverse mobility ratio and channeling of steam may makethis process unattractive.
