Enhanced Oil Recovery (EOR)
Definition - What does Enhanced Oil Recovery (EOR) mean?
Enhanced oil recovery is the use of different techniques that can help in increasing the production of crude oil from an oil well. EOR, an abbreviation of enhanced oil recovery techniques, is sometimes referred to as tertiary or oil recovery. 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.
Petropedia explains Enhanced Oil Recovery (EOR)
Each oil field typically contributes 40% of the oil and gas production, which is an average amount. However, there are certain techniques that can be employed to extract all the identified oil from the reserve without losing it. These techniques are called Enhanced Oil Recovery (EOR). These techniques are used to enhance the recovery factor of the crude oil and improve the production of an oil well. There are basically three major techniques for enhanced oil recovery – chemical injection, gas injection and thermal injection. Gas injection method is the most used EOR technique, followed by thermal injection and chemical injection.
