Distribution of natural gas reserves - 1987/1997/2007
These pie charts shows the % distribution of world natural gas reserves according to geographic region for the years 1987, 1997 and 2007.
Units | 1987 | 1997 | 2007 | |
---|---|---|---|---|
Gas: Proved reserves [15] - Trillion cubic metres (from 1980) | % of total (Tcm) | |||
Total North America - Proved gas reserves | % of total (Tcm) | 9.5 | 5.7 | 4.5 |
Total S. & Cent America - Proved gas reserves | % of total (Tcm) | 4.4 | 4.2 | 4.4 |
Total Europe & Eurasia - Proved gas reserves | % of total (Tcm) | 42.2 | 41.7 | 33.5 |
Total Middle East - Proved gas reserves | % of total (Tcm) | 29.2 | 33.8 | 41.3 |
Total Africa - Proved gas reserves | % of total (Tcm) | 6.9 | 7.3 | 8.2 |
Total Asia Pacific - Proved gas reserves | % of total (Tcm) | 7.9 | 7.3 | 8.2 |
(1) Proved reserves are generally taken to be those quantities that geological and engineering information indicates with reasonable certainty can be recovered in the future from known reservoirs/deposits under existing economic and operating conditions.
(14) Source of data: The estimates in this table have been compiled using a combination of primary official sources, third-party data from Cedigaz.
(15) Trillion equals one million million (1012). 1 trillion cubic feet of natural gas = 26 million tonnes of oil (approximately).
