Thermal Enhanced Oil Recovery (TEOR)
Definition - What does Thermal Enhanced Oil Recovery (TEOR) mean?
Thermal Enhanced Oil Recovery is an oil recovery technique used to reduce the mobility ratio of crude oil in hydrocarbon reservoirs by heating it up in order to vaporize part of it or reduce its viscosity. EOR, an abbreviation of enhanced oil recovery techniques, is sometimes referred to as tertiary or oil recovery. This procedure is helpful in pacing up the flow of crude oil as it reduces the surface tension and improves crude oil permeability. It also helps in easier and faster movement of oil from high pressure zones to low pressure zones.
Petropedia explains Thermal Enhanced Oil Recovery (TEOR)
There are basically three enhanced oil recovery methods which involve thermal, chemical and gas use. By using these techniques, an oil field can be stimulated and boosted to produce more oil and gas. When an EOR method is applied on an oil field, almost 60% of the produce can be extracted from the oil reservoir. If the EOR techniques are not used, any oil field typically contributes 40% of the oil and gas production, which is an average amount.
The gas injection method is the most commonly used EOR technique, followed by thermal injection and chemical injection. Thermal enhanced oil recovery technique can either be achieved by steam flooding or fire flooding.
