Proven reserves refer to the subset of recoverable reserves that have been confirmed through extensive data and analysis to have a high certainty of being recovered, often exceeding a 90% confidence level.
Proven reserves refer to the subset of recoverable reserves that have been confirmed through extensive data and analysis to have a high certainty of being recovered, often exceeding a 90% confidence level. This term is predominantly used in the energy sector, particularly in relation to oil and gas reserves, to indicate the quantity of energy resources that can be recovered with reasonable certainty from known fields under existing economic and operating conditions.
Proved Developed Reserves (PDP) are reserves that are expected to be recovered through existing wells and infrastructures. These reserves include producing wells, which are currently generating resources, and non-producing wells, which have been drilled but may require further investment to start production.
Proved Undeveloped Reserves (PUD) consist of reserves that are expected to be recovered from new wells or projects. These reserves require significant capital investment for development. PUDs often involve additional steps, such as drilling new wells or expanding existing facilities.
Proven reserves must meet stringent criteria to ensure a high degree of reliability. The estimation involves geological and engineering data, and frequently, probabilistic methods are applied to verify the certainty level, which must be at least 90%.
The reporting of proven reserves is subject to strict regulatory frameworks. In the United States, the Securities and Exchange Commission (SEC) has set guidelines for how companies disclose reserve quantities, ensuring transparency and consistency in reporting.
Proven reserves play a critical role in investment decisions within the energy sector. Investors rely on these estimates to assess the value and potential profitability of energy companies.
For governments and regulatory bodies, proven reserves provide essential data for planning and managing natural resources efficiently, ensuring long-term energy security.
Probable reserves have a lower degree of certainty than proven reserves, typically around 50%. These reserves are less certain but still considered likely to be recoverable under favorable economic conditions.
Possible reserves have the lowest certainty, often around 10%, reflecting the quantities that may be recovered under very favorable conditions.
