Proven reserves refer to quantities of natural resources, such as oil or gas, that are confirmed to be recoverable under current economic and operating conditions. These reserves are based on geological and engineering data, ensuring that the resources can be extracted with a high degree of certainty. The classification of proven reserves is crucial for energy companies and investors, as it provides a reliable estimate of future production potential. Accurate assessments of proven reserves help in strategic planning and financial forecasting, influencing decisions related to investments in exploration and production activities in fields like petroleum and natural gas.
