A Couple of Anecdotes
• A famous company misrepresents its reserves with collusion of the board of directors
• Application of revised rules significantly alters management’s previous estimate
• Risk mitigation not in-place results in revision of field reserves
• Management found to be trading shares prior to release of revised reserves estimates
Institute of Mining and MetallurgyLondon, 1911

Principles for Resource Classification
• Project based– Project management
• Classification of total volume• Clear boundaries between categories
– Discovered– Commercial (economic and social license)

Resources are measured against …
Economic to extract (commercially feasible)
Technically feasible to extract
Uncertainty well defined (with high confidence)

Sources of Uncertainty
Successful development plans include contingencies and mitigations for possible outcomes.

Reservoir Technical Limits

• Options– Doable now (or almost)
• Possibilities– Potentially economic– May require incremental
technology development– <5 & >5 yr timescales
• Barrier opportunities– Technical or commercial
barrier– Not currently doable or
uneconomic– Requires step change

The improvement of hydrocarbon recovery and investment efficiency is demonstrably linked with advances in
technology.
The right linkage between depletion and technology plans is vital to
maximising value from our assets.

Resource Identification
• Aids business planning• Investment decisions for individuals and corporations• Allows efficient resource utilisation
• Principally an aid to efficient development

Sustainable Development for All
• Definition must include entire resource base– Maintain competitive advantage– Recognise the total potential
• Over-conservatism may lead to lost opportunity• Uncertainty analysis must identify the components
– Technical– Project– Commerciality and Social License
UNFC-2009 with its focus on economic viability, technical feasibility and uncertainty is well placed to
meet all of these needs.
