4. The global energy landscape is constantly and rapidly evolving in response to advancing
technologies, energy and environmental policies, and in recent years also to an economic crisis
that emphasized widely different growth dynamics among different areas of the world.
In the past decade, the prices of the key energy sources have also shown a high level of instability,
often not justified by the dynamics of demand and supply fundamentals, but rather related to the
speculative behaviour of financial markets.
At this regard, a need has been recently emerging to control energy price volatility, which is
harmful for both producers and consumers and jeopardizes international economic stability, in
other words, a wish to return to energy prices that first of all reflect market fundamentals. To
achieve this, it is helpful to have updated, reliable and exhaustive historical data analyses, in
order to identify the structural trends that will characterize the future energy system purged of
conjunctural or speculative phenomena.
It is in this perspective that Eni is publishing the ninth edition of the World Oil and Gas Review,
an initiative that has led the company to become an outstanding source of information in the oil
and natural gas market.
In this edition you will again find data concerning oil and gas consumption, production, reserves
and international trade for all world countries. These figures are accompanied by specific indicators,
charts and rankings providing an additional key to understanding the data, over and above the
absolute values.
What are the main indications that emerge from an analysis of the latest historical data?
With regard to the oil market, in 2009 consumption decreased by 1.2 million barrels per day
(mbpd) compared to the previous year (-1.4%), primarily as a result of the economic crisis. In the
2005-2009 period, global demand only grew by 1 mbpd, equal to a 1.2% increase. However, this
figure is the result of opposite dynamics that clearly show the existence of two quite different
trends. On the one hand, the developed countries (OECD area), after reaching consumption peak
in 2005, have been moving in the direction of a constant drop, recording a reduction of 4.3 mbpd
(-8.7%). On the other hand, the emerging and developing countries have been heading in the
opposite direction, with consumption rising by 5.4 mbpd (+15.8%) in the 2005-2009 period. This
growth has been driven by China, India, Saudi Arabia and Brazil, which account for 66% of this
increase (34% for China alone).
At January 1, 2010 oil reserves were higher by 13.5 billion barrels (+1.1%) compared to 2009.
The constant growth of oil reserves in the second half of this decade has led the global reserve
life index to rise from 37 years in 2005 to 40 years in 2009. Once again, oil reserves prove to be
a dynamic, increasing value, capable of evolving as a result of changing prices and technologies.

5. The year 2009 was highly turbulent for the gas market as well, with global consumption falling
by 0.8% compared to 2008 (-23.5 bcm). In recent years, however, gas demand has been far more
robust than oil demand, with an 8.7% increase in the 2005-2009 period. This figure was the result
of strongly rising consumption in emerging and developing countries (+13.8%), as well as of
growth in industrialized countries (+3.9%), albeit weaker than in the past, particularly in the last
few years. In the latter regions, environmental benefits compared to other fossil fuels open further
space for growth in the natural gas market, particularly in the power generation sector. Significant
news are also observed on the production side. In 2009, following a boom in unconventional
gas (primarily shale gas), the United States became the leading world producer with 583 bcm,
overtaking Russia, the historical leader of this ranking. The US growth in gas production is one
of the most evident ongoing trends in the natural gas market, with an increase of approximately
80 bcm (+16%) in the 2005-2009 period, a figure close to current Italian annual consumption.
Qatar’s production has also risen rapidly, to the point of doubling from 2005 to 2009.
Global gas reserves have also increased significantly (+4.8% at January 1, 2010 compared to the
same date in 2009), continuing a trend that led them to rise by 10.3% compared to January 1,
2005. In 2009 the life index grew from 58 to 60 years, and it is likely to reach above the 60 year
level soon.
The statistics contained in the World Oil and Gas Review provide a comprehensive account of this
and other market dynamics.
We submit these statistical pages to your analysis, in hope that this edition will once again prove
to be a helpful work and study tool.

9. Introduction
Areas and aggregates
This Review adopts the most commonly used names for countries and not necessarily the official name.
The names used do not in any way indicate the opinion of Eni on the legal status of countries,
territories, cities or areas mentioned. The term “country” is used to indicate, when necessary, also a
territory or area. Borders between countries are indicated on the maps and do not imply judgement
of any kind or the position of Eni with regard to current international disputes.
For operational and analytical purposes, economies are divided among income groups according
to 2008 Gross National Income (GNI) per capita, calculated using the World Bank Atlas method,
in effect until 1st July 2010. The groups are: low income, $975 or less; lower middle income,
$976–3,855; upper middle income, $3,856–11,905; and high income, $11,906 or more. Classification
by income does not necessarily reflect development status.
Other analytical groups based on geographic regions are also used.
Eni regrets that it is not able to supply further information on the data presented in this Review, apart
from the methodological notes.

10. Introduction
Notes and methods
The sources of the data are: Arab Oil & Gas Directory, Bureau of Labor Statistics, Cedigaz, Enerdata, Eni, International Energy Agency, IHS Energy,
International Monetary Fund, Italian Ministry for Economic Development, Oil & Gas Journal, PIW, Platt’s, Wood MacKenzie and other official sources.
Measurement units used are: thousand barrels per day (oil) and billion cubic metres per year (natural gas).
The figures for reserves are expressed in millions of barrels (oil) and billions of cubic metres (natural gas) and refer to proven reserves as at 1st January.
The figures for other chapters indicate annual averages.
Blank spaces in the tables indicate that the figure was not available, zero indicates a figure that is not significant (except for the chapter
“International Trade”).
Total may differ from the sum of the individual figures as a result of rounding up/down.
In the chapters “Production” and “Consumption” of oil, in some countries figures may include oil from non conventional sources and others
sources of supply.
The difference between the consumption and the production of oil is given by the change in stocks, the processing gains obtained in refining and the
amount of biofuels which is not included in production.
Gas production, consumption, exports and imports are assessed by using the same calorific value per cubic metre (39MJ/cm, GCV), in order to make
data among countries comparable.
In the chapter “Production” of natural gas, the figures concern traded production and do not include quantities of burnt, dispersed or re-injected gas.
The data in the chapter “Reserves/production ratios” have been obtained by dividing the reserves of a given year by production for the same
year. The calculation of the relation between reserves and oil production: annual production is multiplied by 365; for Saudi Arabia and Kuwait the
country production figure is used plus half of the production of the Neutral Zone; for Canada the production level considered is that of conventional
oil production.
Introduction
The figures in the chapter “Per capita consumption” have been obtained by dividing the consumption of a given year by the population in the same
year. For oil, annual consumption is multiplied by 365, before being divided by the population.
The figures in the chapter “Production/consumption ratios” have been obtained by dividing the production of a given year by consumption for
the same year.
IV In all the chapters, the list of the “first ten countries” is drawn up by ordering the countries on the basis of the last available year. In the chapters
“Reserves/production ratios” and “Production/consumption ratios”, the list of the “first ten countries” is drawn up by selecting the largest
producers in the last available year and ordering them on the basis of the value of the reserves/production and production/consumption ratios. In the
chapter “Per capita consumption”, the list is drawn up by selecting the largest consumers in the last available year and ordering them by the value
of per capita consumption.
In the chapters “Exports” and “Imports” of natural gas”, the figures for a country’s exports and imports may differ from those reported in the
chapter “International Trade” for the same country, because of the different source of information and the different calorific value attached
to the cubic metre. As far as Italy is concerned, the series of gas imports (source of information: Italian Ministry for Economic Development), is
not homogeneous because from 1995 to 2001 it includes imports on the basis of the contractual origin of the gas, and from 2002 on, it takes
into consideration the country of physical origin.
In the chapter “International Trade” of natural gas, trade figures for the United States include also the trade of Portorico.
In the chapter “Production quality” figures for total oil production in each area or country do not coincide with the figures in the “Production”
chapter. This is due to the exclusion of natural gas liquids and extra heavy crude from the figures for the first (except for Venezuela). Moreover, it has
not been possible to allocate or define total production. In some countries the ‘Ultra Light’ category also includes, in total or in part, the production of
condensates. For Canada the production includes syncrude.
For the definition of the qualitative parameters for single crudes, the data of “Eni R&M Division–San Donato Research Center–Downstream technolo-
gies” have been used, wherever possible. Quality levels, indicating API gravity and sulphur content, are defined as follows.
Ultra Light API level equal to or greater than 50° and a low sulphur content
Light & Sweet API level equal to or greater than 35° and less than 50°; sulphur content less than 0.5%
Light & Medium Sour API level equal to or greater than 35° and less than 50°; sulphur content equal to or greater than 0.5% and less than 1%
Light & Sour API level equal to or greater than 35° and less than 50°; sulphur content equal to or greater than 1%
Medium & Sweet API level equal to or greater than 26° and less than 35°; sulphur content less than 0.5%
Medium & Medium Sour API level equal to or greater than 26° and less than 35°; sulphur content equal to or greater than 0.5% and less than 1%
Medium & Sour API level equal to or greater than 26° and less than 35°; sulphur content equal to or greater than 1%
Heavy & Sweet API level equal to or greater than 10° and less than 26°; sulphur content less than 0.5%
Heavy & Medium Sour API level equal to or greater than 10° and less than 26°; sulphur content equal to or greater than 0.5% and less than 1%
Heavy & Sour API level equal to or greater than 10° and less than 26°; sulphur content equal to or greater than 1%
