Notes: Proved reserves of oil - 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. |
|
|
|
|
Reserves-to-production (R/P) ratio - If the
reserves remaining at the end of any year are divided by the production in that year, the result is the
length of time |
|
that those remaining reserves would last if
production were to continue at that rate. |
|
|
|
|
Source of data - The estimates in this table
have been compiled using a combination of primary official sources and
third-party data from Cedigaz and the OPEC Secretariat. |
