This two-day course is designed to provide an improved understanding of the processes underlying petroleum resource assessments. SEC, Canadian (NI 51-101), and SPE reserve and resource classification guidelines are examined and compared; extensions and modifications that better support both internal portfolio management and regulatory reserves disclosures are discussed. Fundamental deterministic and probabilistic assessment approaches are reviewed; class exercises are used to demonstrate integrated methodologies that provide improved quality assurance. A complete set of course materials and lunches are included.
