NOTES TO THE TABLES

I. Note on Sources

The data published in Oil & Energy Trends Annual Statistical Review are 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 every source 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 many developing 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 Republic only from 1993 onwards.

b) Germany refers to the former Federal Republic of Germany only up to 1990, and to the reunified Germany from 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 by the former Yemen Arab Republic and The People’s Republic 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 Yugoslavia up 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. Outlying dependencies, 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 reserves from 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 converting the 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 over the years.

Israel: Includes production in Israel-occupied Sinai in the years 1970 and 1973.

Cote d’Ivoire was revised and updated in 2015, with consequent changes 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. (contd on next page)
