What type of reserves can be estimated with reasonable certainty to be recoverable under current economic and technological conditions?

What type of reserves can be estimated with reasonable certainty to be recoverable under current economic and technological conditions?

• A. Proved Reserves
• B. Probable Reserves
• C. Possible Reserves
• D. Contingent Resources

Answer: (A)

Proved reserves are the most certain category because they are defined as the volumes that can be recovered with reasonable certainty under existing economic conditions and using current technology from known reservoirs. This means thorough geological and engineering evidence shows these amounts are recoverable with the equipment, facilities, and practices already in place, assuming current prices and costs. They can include both developed and undeveloped areas, as long as they meet that high confidence in recoverability. In contrast, probable and possible reserves reflect lower levels of certainty about recoverability, and contingent resources are not yet considered recoverable under current conditions.
