Notes: The published reserves figures rely on survey responses
and official updates released by individual countries, which are not provided
every year in many cases. OGJ changes its estimate for a particular country
only when it receives evidence that a change is in order. Therefore, in a given
reserves summary, a year-to-year change may not necessarily reflect a change
that applies to the calendar year alone. According to the Norwegian
Petroleum Directorate data, Norway's proved reserves of oil declined 5.6% to
5.5 billion bbl. Please read Conglin Xu and Laura Bell, "Global reserves,
oil production show increases for 2014", OGJ, Dec. 1, 2014.
Proved/proven oil reserves - 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.
