Proved reserves of gas in trillion cubic meters. The estimates in this variable have been compiled using a combination of primary official sources and third-party data from Cedigaz and the OPEC Secretariat.
Total proved reserves of natural gas - Generally taken to be those quantities that geological and engineering information indicates with reasonable certainty can be recovered in the future from known reservoirs under existing economic and operating conditions. The data series for natural gas does not necessarily meet the definitions, guidelines and practices used for determining proved reserves at company level, for instance as published by the US Securities and Exchange Commission, nor does it necessarily represent the EI’s view of proved reserves by country.
As far as possible, the data above represents standard cubic metres (measured at 15ºC and 1013 mbar) and has been standardized using a Gross Calorific Value (GCV) of 40 MJ/m3.
