Oil And Gas Reserve Classification

This problem tests whether you understand the reserve classification framework used in oil and gas, especially the relationship between proved, probable, and possible reserves and the confidence levels attached to each estimate. In interviews, this matters because reserve terminology comes up often in upstream analysis, valuation, and discussions of asset quality, risk, and forecasting. Candidates are expected to know how engineers and analysts think about uncertainty in recoverable volumes and why companies and investors rely on these categories when assessing the reliability of a resource base.
