Developments of Energy Resourrces
and in Canada by 203 billion cubic meters. The reserves remarkably
increased in the CIS and particularly in Russia andAzerbaijan, where
reserves increased by 232 and 121 billion cubic meters respectively.
Chinese gas reserves increased by 16.1% from 3.04 trillion cubic
meters, to 3.5 trillion cubic meters. On the other hand, gas reserves
estimates declined in the UK from 253 billion cubic meters in 2011,
to 246 billion cubic meters in 2012. Such a decline could have been
one of the reasons why the UK permitted the hydraulic fracturing
in the unconventional gas reserves as early mentioned. No changes
were recorded in the USA gas reserves estimates.
3. Hydrocarbon Liquids & Natural Gas Production
3-1 Hydrocarbon Liquid Production
Oil production covers both crude oil and condensates production,
while hydrocarbon liquids production covers crude oil, condensates
and natural gas liquids (NGLs) as well.
3-1-1 Oil Production
Estimates show that world oil production increased by 4.3%
from 72.2 million barrels per day in 2011 to 75.3 million barrels
per day in 2012. Natural gas liquids production was estimated at
about 7.5 million barrels per day in 2011, which is 9.9% less than
2010 volumes. The total estimated production of hydrocarbon
liquids in 2012 was about 82.8 million barrels per day, which is
about 3 million barrels per day more than 2011 estimates.
