There is great difference between the petroleum resources used in China and the concept of resources commonly used in the world

which would easily result in confusion and misunderstanding. So

we especially regard the resources used in China as geological resources

which can be called recoverable resources after it has been revised with its economic availability and predicted recovery.It can then be approximately correlated with the resources in the world. Based on the composite volume of proved reserves and geological resources in 2000 to be 1035?10

t

and the recoverable resources is calculated to be 116.1?10

t

correspondingly

the degree of resources to be proved is 52.2%. After averaging the 16 values independently estimated by different geological experts in different periods

the recoverable resources is about 132.5?10

t. Being compared to the equivalent values

the recoverable oil resources in China is slightly higher than that of natural gas.For both resources and undiscovered oil recoverable resources

eastern China ranks first

and the second would be north-western China and the continental shelf.
