Reserves & Resource Classification (Descriptive)
Inside this lesson
- Distinguish reserves (discovered, recoverable, commercial) from the wider category of resources (including contingent and prospective resources)
- Describe how reserves are graded by certainty under industry frameworks such as SPE-PRMS: proved (1P), plus probable (2P), plus possible (3P)
- Explain the parallel commercial-maturity axis: reserves versus contingent resources versus prospective resources
- Contrast deterministic estimation (single best values) with probabilistic estimation (ranges and P90/P10 outcomes), and recognise that the course describes how volumes are classified - it does not book, certify, or audit anyone's reserves
