4 Scope of Case Studies (1) To Demonstrate how UNFC can be used with different national classifications (Norway, Poland, Russian Federation, Ukraine) To demonstrate that UNFC can be used at all levels: Deposit / Field Norway: Gullfaks Field Poland: Barnowko-Mostno-Buszewo and Koscian Fields Venezuela: Orinoco Belt National / Portfolio Norway Poland Venezuela 15/11/2005 P. Blystad, 2005: Case Studies UNFC 4

5 Scope of Case Studies (2) Setting Onshore Offshore Petroleum type Conventional oil Non-conventional oil Gas Accumulation size Very large Medium Small UNFC has been demonstrated to be applicable in different settings. Focus upon Case Studies as support for the Guidelines / Specifications 15/11/2005 P. Blystad, 2005: Case Studies UNFC 5
