Estimated Ultimate Recovery (EUR)

byEnverus

Estimated Ultimate Recovery (EUR)

Estimated ultimate recovery (EUR) refers to the total quantity of oil or gas that is expected to be economically recoverable from a reserve or well over its productive life. It is a critical metric used by energy companies, analysts and investors to assess the viability, profitability and valuation of exploration and drilling projects. EUR is typically broken down into three categories based on confidence levels: Proven Reserves (90%+ certainty), Probable Reserves (50%+ certainty), and Possible Reserves (<50% certainty). This estimate influences financial modeling, investment decisions and project planning.

Frequently Asked Questions

How is EUR calculated?

EUR is calculated using historical production data, reservoir characteristics and recovery technology. It often involves simulation models and statistical methods to estimate future recoverable volumes, requiring several months of production data for accuracy.

What factors influence changes in EUR over time?

EUR can change due to technological advancements, oil price fluctuations and infrastructure improvements. For example, higher oil prices may make previously uneconomical reserves viable, increasing the EUR.

What are the categories of EUR and what do they mean?

EUR is divided into Proven Reserves (90%+ chance of recovery), Probable Reserves (50%+ chance), and Possible Reserves (<50% chance). These categories reflect the confidence level in the recoverability of the resource using current technology.

How does EUR affect corporate financial reporting?

EUR impacts asset valuation, depreciation schedules and future revenue projections. It is often disclosed in financial statements and investor reports to provide transparency about a company’s resource base and future earning potential.
