Petroleum (gas) was discovered in China 2000 years ago
China started the development of modern oil and gas industry.
Ministry of Petroleum issued a geologic reserve estimation guideline.
Research Institute of Petroleum E&D set up criteria for oil and gas reserves
estimation.
China National Mineral Reserves Committee was formed and devoted to
the promotion of integrated study and setting of mandatory criteria for oil
and gas reserves estimation.
China National Standard Bureau issued the Committee’s criteria.
Ministry of Land and Resources (MLR) was set up.
MLR has organized the amendment of the standard and criteria considering
UNFC/SPE definitions.
The newly amended system was approved and issued by the General
Administration of Quality Supervision, Inspection and Quarantine of
P.R.China, and effective in 2005.

Chinese Petroleum Resource Classification System
�Geological knowledge based three-class system
�Classification is based on the phases or the maturity of
E&D, according to geology knowledge gained.
�Different data requirements are assigned to different
classes of reserves to ensure the E&D phases and
certainties required
�The classes of recoverable reserves are related to the
geologic reserves
�Thresholds of industrial flow are used to be
commercial criteria
Basic Features
6
� Consist with international standards, UNFC, PRMS, SEC, etc.
� Keeping continuity on basic major features of the system by taking the history and reality of standards in China into account; such as three-class-framework, categorizing principals, etc.
� aligns the SPE/SEC definitions of Proved reserves and parts of those considerations of Probable and Possible reserves of SPE;
� Adopts international comparable terminology of reserves (3P system) for the use of international cooperation, evaluation and study;

Discussion
�Challenges for National Oil Companies
�Challenges for current standards to manage
unconventional resources
�Application promotion of UNFC 2009
Challenges for National Oil Companies
Obligations
Sustainable energy supply, effective resources management,
business processes and financial reports.
Challenges
to meet multi-goal requirements, face various standards, huge
workload every year, great amount of data……
Solution ?
� clarify ideas in targeting, planning, organizing……
� to find more effective way or tool……
� to establish/construct consistent resources-database system……
Challenges for Unconventional Resource
Characteristics
distribute extensively without apparent WOC, no clear phases of exploration and Development, easy to ‘discovery’ but difficult to recovery, high heterogeneity in qualities, more complex storage processes ……, in a word, less certainty with more risk.
Sketch map of conventional and unconventional resources distribution, Zou Caineng,2010
Challenges for Unconventional Resource
Challenges
Based on current standards, no big changes in categories, but major
ones are just P1 and resource……
How to manage effectively ?
Strategy policies in upgrading?
Development tendency ?
� more and further works may needed in exploration categories ……
� corresponding relations among E,F,G categories increase ……

Resources
Application Promotion of UNFC 2009
Advantages
Universally acceptable and internationally applicable, powerful
(strong code) ……
Challenges
Aims to overlap most requirements and systems, and work more instructively and effectively……
Suggestion ?
� Let more people know, understand, and adopt
training, work shop, free assistance, joint-study, etc.
� Strong technical supports for development
