NOTES TO THE TABLES
I. Note on Sources
The data published in Oil & Energy Trends Annual Statistical Revieware drawn from a great variety of sources, mainly the official government
statistics of the countries concerned, international organisations, trades associations, oil companies,press releases, and other trade publications.
It is not possible to acknowledge everysource for each of the tables. However, in general, national official sources, when available,have been
used wherever there is a conflict with other sources.
For the OECD countries, the national trade statistics of member countries have been used extensively as well as the governments’statistical
publications specialising in energy. For manydeveloping countries, the annual reports of the national oil companies have been an invaluable
source. In the major oil producing countries, the energy ministries’statistical publications have been especially useful. Among international
organisations, the principal sources used are the United Nations, OECD, EU, and OPEC.
II. Notes to the Tables
General notes to all Tables:
a) Czech Republic refers to the former Czechoslovakia up to 1992, and to the Czech Republiconly from 1993 onwards.
b) Germany refers to the former Federal Republic of Germany only up to 1990, and to the reunified Germanyfrom 1991 onwards.
c) The former German Democratic Republic is included under Non-OECD until German reunification in 1990.
d) CIS/FSU refers to the 15 member of the former Soviet Union up to 1991, and to the 12 members of the Commonwealth of Independent
States from 1992 onwards.
e) Yemen refers to the territory covered bythe formerYemen Arab Republic and The People’sRepublic of South Yemen up to 1989, and to the
reunified Republic of Yemen from 1990 onwards.
f) Yugoslavia refers to the six members of the former Socialist Federal Republic of Yugoslaviaup to 1991, and to the two remaining members
only of the Federal Republic of Yugoslavia(Serbia and Montenegro) from 1991 onwards.
g) Kuwait and Saudi Arabia include their share of the Neutral Zone where it is not listed explicitly.
h) In as far as possible other countries include the area covered by the state’s“metropolitan”territory. Outlyingdependencies, etc are listed
explicitly.(see also “Geographical and Geopolitical Coverage”).
Table 1: World Proved Crude Oil Reserves
Canada: Includes estimate of Canadian oil sands ’under active development’as a proxy for proved reservesfrom 2010.
Table 2: World Proved Natural Gas Reserves
Malaysia: Included in Brunei for the years 1970 and 1973. Bangladesh: Included in Pakistan for the year 1970.
Due to an error the series “Total Western Hemisphere”excluded the figures for Canada and Mexico, and “Total CIS/FSU”excluded the figure
for Armenia in Volumes 30 to 35. The series have been corrected and “Total World”has been updated accordingly.
Table 3: World Crude Oil and Natural Gas Liquids Production
General Note: Includes lease/field condensate.
Canada: Includes synthetic crude, experimental and bitumen, pentanes plus and other NGL.
United States: Excludes fuel alcohol and liquid hydrocarbons other than crude oil, condensate and NGL.
United Kingdom: Combined crude oil and NGL stream produced in the UK has become significantly lighter in recent years, and account has
been taken of this in convertingthe original data in metric tons to the volume figures shown in the table. Volume figures shown are consequently
higher than those appearing in some other sources which have used a fixed conversion factor overthe years.
Israel: Includes production in Israel-occupied Sinai in the years 1970 and 1973.
Cote d’Ivoire was revised and updated in 2015, with consequentchanges to regional and world totals.
Table 4: World Natural Gas Liquids Production
General Note: Excludes field/lease condensate except United Kingdom, Indonesia, Thailand, Algeria, and Egypt.
Table 5: World Natural Gas Production
General Note: Table excludes gas flared and quantities re-injected, except where otherwise noted. Germany and Poland: Includes quantities re-
injected.
Table 7: World Primary Electricity
General Note: Includes Nuclear, Hydro, and other non-conventional thermal. (e.g., wind and geothermal)
Table 8: World Primary Energy Production
General Note: Primary electricity is converted to barrels of oil equivalent on the basis of physical energy. (continued on next page)
