Estimated Ultimate Recovery (EUR)


Estimated Ultimate Recovery (EUR) is a forecast used in the oil and gas industry to predict the potential total amount of extractable resources from a specific energy reserve. It considers various factors such as the reserve’s physical characteristics, efficiencies in extraction techniques, and recovery rates. This estimation is crucial for businesses and investors as it impacts projected revenues, profitability, and investment decisions.


Estimated Ultimate Recovery (E-U-R) is typically pronounced as:”Eh-stuh-may-ted Ul-ti-mayt Ri-kuhv-uh-ree”

Key Takeaways

Estimated Ultimate Recovery (EUR) is a crucial concept in the oil and gas industry. Here are three main takeaways about it:

  1. Predictive Measurements: EUR’s primary purpose is to predict the total amount of producible resources from a reservoir. This assessment gives valuable insights into the potential profitability of a well or oil field over its lifetime.
  2. Key Determinant for Investment: EUR impacts the decision-making process in the oil and gas industry. Oil companies depend on the EUR to identify profitable ventures and steer clear of those with lower predictions. Thus, it is influential in defining investment and development strategies.
  3. Accuracy Matters: The accuracy of EUR estimations is paramount for future planning and profitability. Errors or inaccuracies can lead to ineffective planning and significant financial losses. Consequently, a thorough understanding and constant refinement of estimation models are vital.


Estimated Ultimate Recovery (EUR) is a crucial term in business and finance, particularly in the oil and gas industry, as it provides a prediction of the total amount of recoverable resources that will be extracted from a well or a field over its productive life. This estimation can significantly impact the decision-making process regarding the profitability and feasibility of investing in a particular project. It serves as a basis for financial forecasts, risk assessments, and capital allocation. Therefore, precise EUR calculations can lead to improved overall business planning, optimal resource allocation, and maximized profits. Furthermore, EUR estimates can influence a company’s valuation in the market, contributing to its overall financial strategy.


The Estimated Ultimate Recovery (EUR) is an essential term in the oil and gas industry that serves a crucial role in valuing these resources. The primary purpose of EUR is to project the total amount of extractable hydrocarbons from a particular reservoir. Accurate predictions of EUR allow companies to make informed decisions about future operational strategies, including plans for drilling and production schedules, thereby contributing to optimal resource management and maximizing profits. Essentially, the EUR is an indicator of the reservoir’s profitability, and hence, is pivotal to investment decisions.Furthermore, EUR plays an instrumental role in the financial assessment and valuation of oil and gas companies. Investors typically evaluate the performance of these corporations based on their reserves’ estimated recoverable volumes, a function directly associated with the EUR. Thus, if a company’s EUR figures are robust, it may attract increased investment. Additionally, accurate estimation of EUR assists in preventing wastage of resources and ensuring environmental sustainability in hydrocarbon extraction processes. In inaccurate estimates could result in either overexploitation or underutilization of resources; hence, EUR is vital for maintaining a balance between profit and sustainable practices.


1. An Example from the Oil & Gas Industry: A petroleum company may use Estimated Ultimate Recovery (EUR) to evaluate the potential profitability and lifespan of a new oil or gas well. For instance, Company X’s geoscientists and engineers predict that a recently drilled well will ultimately produce 1 million barrels of oil. This estimate helps the company make decisions regarding future investment in infrastructure around the well, such as pipelines and storage facilities.2. An Example from Renewable Energy Sector: A solar energy company might evaluate the Estimated Ultimate Recovery (EUR) of a new solar farm. After assessing the maximum possible energy output and the expected lifespan of the solar panels, they anticipate that the farm will ultimately produce 1 terawatt-hour of electricity. This information could guide decisions about modernizing the panels or investing in additional energy storage solutions.3. An Example from Mining: A gold mining company might use the estimated ultimate recovery (EUR) to forecast how much gold can be extracted from a new mine. After conducting geologic surveys and tests, the company determines that they will be able to ultimately recover 200 tons of gold from the mine. This EUR helps them calculate potential long-term revenues and influences decisions regarding the scale of extraction operations.

Frequently Asked Questions(FAQ)

What is Estimated Ultimate Recovery (EUR)?

Estimated Ultimate Recovery (EUR) is a term used in the oil and gas industry to predict the total amount of resources a reservoir or well will produce over its entire productive lifespan.

How is EUR calculated?

EUR is calculated using a variety of factors such as initial production rates, decline rates, recovery factor, as well as the quality and quantity of resources in the reservoir. Sophisticated modeling techniques and data analysis are required to make this prediction.

What is the significance of EUR in the oil and gas industry?

EUR is a crucial value for companies in the oil and gas industry as it helps them determine the profitability and feasibility of drilling in a particular reservoir. It informs decisions related to exploration, development, and production investment.

Can the EUR change over time?

Yes, the estimated ultimate recovery of a well can change over time. This is due to changes in well performance or updates in forecast methodologies. Also, implementing enhanced recovery methods can also change the EUR.

How is EUR used in financial planning for oil and gas companies?

EUR is used to estimate the revenue that a well might generate over its lifespan. This information is invaluable for financial forecasting, investment budgeting, and long-term planning.

What happens if the actual recovery is less than the EUR?

If the actual recovery is less than the Estimated Ultimate Recovery, it could indicate a variety of issues, such as technical problems with extraction, lower-than-expected reservoir quality or inaccurate initial assessments. It may also cause financial losses and missed production targets.

How reliable is the EUR as a prediction tool?

The reliability of EUR largely depends on the quality and accuracy of the data input and the reservoir modeling. While it’s a pivotal guide, it remains an estimate and there is always a potential for deviation in actual recovery.
