One popular EOR technique is thermal recovery, which involves injecting steam or hot water to heat the crude oil. In-situ combustion, or fireflooding, is another thermal technique where an oxygen supply is introduced to ignite the oil within the reservoir.

By pushing the oil from the injection wells toward production wells, this process forces the remaining crude out of the rock pores. At this stage, the recovery rate is relatively low, often leaving the majority of the oil trapped in the rock matrix, and signaling the need to transition to enhanced recovery methods.
By reducing the viscosity of the oil, the heated fluid flows much more easily through the rock and toward the production wells. Secondary Recovery: Water and Gas Drive When primary recovery slows to an uneconomic pace, operators move to secondary recovery techniques to maintain output.

Primary Recovery: The Natural Flow Oil extraction begins with primary recovery, a phase that relies on the natural energy already present within the reservoir. Thermal Methods: Steam and Fireflooding Thermal recovery is particularly vital for heavy oil deposits, where the viscosity is so high that the oil barely flows at room temperature.
