Definitions for "Tertiary Recovery"
The recovery of oil that involves complex and very expensive methods such as the injection of steam, chemicals, gases, or heat, as compared to primary recovery, which involves depleting a naturally flowing reservoir, or secondary recovery, which usually involves repressuring or waterflooding.
Recovery of hydrocarbons from a reservoir by sophisticated methods, for example, heating reservoir or enlarging pore spaces using chemicals. (see also Primary and Secondary Recovery)
Enhanced methods for the recovery of oil and natural gas that require a means for displacing the oil or natural gas from the reservoir rock, modifying the properties of the fluids in the reservoir and/or the reservoir rock to cause movement of the oil or natural gas in an efficient manner and providing the energy and drive mechanism to force its flow to a production well.
