(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).
