What is Estimated Ultimate Recovery (EUR)?
Estimated Ultimate Recovery (EUR) is a mystical term in the realm of oil and gas exploration, representing the total amount of oil or gas that can be potentially recovered from a reserve or well over its productive life. It’s like that magic number you hope to hit at the casino—but instead of chips, it involves barrels of crude and cubic feet of natural gas! 🎰💧
Definition
Estimated Ultimate Recovery (EUR) is an estimate reflecting the total quantity of oil or gas that a particular well or field can ultimately yield, encompassing hydrocarbons that have already been recovered and those still to be produced.
EUR vs Recoverable Reserves Comparison
| Estimated Ultimate Recovery (EUR) | Recoverable Reserves | |
|---|---|---|
| Definition | Total estimate of potential production from a well/field | Specific quantities of oil or gas that can be recovered |
| Confidence Levels | Includes categories of proven, probable, and possible reserves | Often classified into proved, unproved, and probable |
| Time Frame | Represents the entire life of the reservoir | Typically refers to a specific time span or project |
| Users | Used by companies and investors to gauge potential profits | Primarily utilized in financial reporting and audits |
Examples of EUR in Action
- An oil well showing an EUR of 1 million barrels implies that, over its life, an estimated total of 1 million barrels can be produced—this includes what’s been pumped out already plus what’s left in the ground.
- If an oil company estimates that there are 500,000 barrels as proven reserves and an additional 300,000 as probable, the EUR total could be stated as approximately 800,000 barrels.
Related Terms
- Proven Reserves: These are economically recoverable quantities of crude, confirmed by drilling and production.
- Probable Reserves: Reserves that are less certain than proven but are estimated likely to be recovered.
- Possible Reserves: These are quantities that may be recoverable but involve significant uncertainty.

Fun Fact
Did you know that the oil and gas industry’s estimated ultimate recovery figures were previously based on crystal ball readings until the invention of more scientifically reliable methods? Just joking—they were based on educated estimates, historical production data, and geology magic! 🔮
Frequently Asked Questions
