How much oil is left in the world?

The world's oceans cover an area of 100 million square kilometers, about twice the size of the land. The continental shelf and continental slope are about 55 million square kilometers, which is equivalent to the total area of terrestrial sedimentary basins. 1 4 of the proven oil resources and 45 of the final recoverable reserves on the planet are buried on the seabed.

The center of gravity of the world's proven oil reserves will likely shift from land to sea. In the history of modern petroleum, the Western Hemisphere has been the main reservoir of the world's oil resources for a hundred years. After World War II, the Eastern Hemisphere replaced the Western Hemisphere as the world's main reservoir of oil resources.

The existing reserves in the eastern hemisphere are 96 billion tons, which is five times that of the western hemisphere, the potential reserves are 105 billion tons, which is twice that of the western hemisphere, and the final recoverable reserves are 225 billion tons, which are times that of the western hemisphere, accounting for about 74 of the world's final recoverable oil reserves. Among them, the reserves and final recoverable reserves in the Middle East alone are times and times that of the Western Hemisphere, respectively. In various regions of the world, the ** breed varies greatly.

According to the severity, there are three types: light, medium and heavy; According to the sulfur content, there are three types: low sulfur, sulfur and high sulfur. **Varieties can be divided into low sulfur light oil, sulfur light oil, sulfur medium oil and heavy oil, high sulfur medium oil and heavy oil, etc. Low sulfur light oil has the highest economic value and is the best among the best, mainly concentrated in Africa, the North Sea and Southeast Asia.

There are many sulfur-containing light oils, mainly distributed in the Middle East and Russia. The largest number of sulfur-containing medium oil, heavy oil and high-sulfur medium oil and heavy oil are mainly distributed in the Middle East and Latin America.

How much oil reserves are there in the world right now? About 1.15 trillion barrels have been proven. While this is a 10 percent increase from the previous two years' estimates, at the current rate of extraction, there are only enough oil reserves on the planet to meet the world's oil consumption for 41 years.

The world's oil reserves are mainly distributed in the Middle East, Latin America, Europe, Africa, Asia and North America. The top 10 countries in terms of reserves are Saudi Arabia, Iraq, Kuwait, the United Arab Emirates, Iran, Venezuela, Russia and Central Asian countries, Mexico, the United States and China. Among them, Saudi Arabia has the largest proven reserves, accounting for 25% of the world's total reserves, which can be mined for more than 90 years.

Iraq, Kuwait, the United Arab Emirates and other countries can mine for more than 100 years each, while the United States can only mine for 10 years based on current production. The estimated proven reserves and production of major countries in the world are ranked as follows: Sort by country and region Oil reserves (10,000 tons) Sort by country and region Oil production (10,000 tons) 1 Saudi Arabia 1 Saudi Arabia 42150 2 Canada 2 Russia 41080 3 Iran 3 United States 28625 4 Iraq 4 Iran 18650 5 Kuwait 5 China 17075 6 Abu Dhabi 6 Mexico 16825 7 Venezuela 7 Norway 15175 8 Russia 8 Canada 11100 9 Libya 9 Nigeria 10600 10 Nigeria 10 United Kingdom 10475

There is no such thing as an estimate, because many of the figures are estimated, there are too many assumptions and uncertainties, and new fields are being discovered as they are being exploited.

According to the known statistics, they are the following ten countries.

10. Nigeria.

Nigeria is Africa's largest producer, with proven oil reserves of 35.3 billion barrels.

9. Libya.

Libya has abundant ** resources, of which proven oil reserves are 39.1 billion barrels, Libya ** production has reached 1.6 million barrels per day, domestic consumption is about 250,000 barrels per day, and net exports are about 1.2 million barrels per day.

2. Saudi Arabia.

Saudi Arabia has the largest oil reserves in the world, and 90% of the country's economy comes from exporting petroleum fuels. With 265 billion barrels of oil reserves, Saudi Arabia has the highest oil reserves in the world.

1. Venezuela.

Venezuela has proved oil reserves of 296 billion barrels in recent years, making it the country with the largest proven oil reserves in the world. However, Saudi Arabia's oil exports are still not comparable.

At present, Venezuela has the largest proven oil reserves, which means that Venezuela has the most recoverable oil at present, but the United States is currently the most produced, with an average daily output of about 12 million barrels per day.

Venezuela. Venezuela has the largest oil reserves in the world. It is an important oil producer and exporter.

Petroleum is a natural chemical raw material and an important resource, because of its importance, it is called "the blood of industry", which shows the role of oil in industry. The country with the largest oil reserves in the world is currently Venezuela.

The importance of oil is self-evident, and there are two theories about whether oil is a renewable resource, one is that oil has evolved over a long period of time and is a non-renewable resource. Another theory is that oil is produced by carbon in the earth's crust and is a renewable resource.

The historical origins of oil

Oil is an indispensable raw material for chemical industry, as early as ancient Egypt and ancient Babylon, there are records of oil extraction, at that time, people began to use asphalt to bond walls to waterproof. Later, people collected oil for fuel and used it in wars.

In the 19th century, a pharmacist invented kerosene lamps, and kerosene lamps became popular. China's oil resources are also very rich, as early as the Song Dynasty, Shen Kuo named this liquid that can cook, light and heat. <>

Which country has the largest oil reserves in the world?

Many countries in the world have a lot of oil reserves, and a lot of oil reserves means that they are rich in resources. In the world, the country with the largest oil reserves is Venezuela. Oil is measured in barrels, and one ton is approximately equal to seven barrels.

In 2018, Venezuela had confirmed oil reserves of nearly 300 billion barrels, ranking first in the world. Venezuela is also one of the largest oil exporters to the United States. The abundant oil resources became the backbone of the country's economy. <>

Our country is also rich in oil resources

In the ranking of global petroleum resources, the reserves of China's petroleum resources are also among the top ten. There are more than 100 billion barrels of proven oil reserves. China's oil fields have now developed to more than 500, the most famous are Daqing Oilfield, Shengli Oilfield, Liaohe Oilfield in Northeast China, North China Oilfield in North China, Karamay and other oilfields in Northwest China.

Venezuela is because there is a lot of oil, so their country does not need to develop other industries, and they can live very rich.

Saudi Arabia, their oil reserves are very high, they export more oil, and the country is relatively rich.

Saudi Arabia, this place has a lot of oil, and they all live a very happy life on oil.

The country with the largest reserves is Venezuela, which has the largest oil reserves in the world, with reserves of about 296 billion barrels.

Saudi Arabia is this country, and this country can now be said to have the largest oil reserves in China. It can be said that it is the kingdom of oil.

Introduction: People know that oil is a very important energy source, and oil is very versatile, but oil is also a non-renewable energy source. How exactly is oil formed? Why is there so much oil on the planet?

In fact, through the composition of petroleum, we can roughly understand the main substances formed by oil**, because petroleum is mainly a hydrocarbon, and energy can be released in the process of combustion, so as to promote some power. Some people believe that oil was formed by ancient organisms, because there were many plants on the surface of the earth in the past. Most of these plants are very luxuriant and abundant.

Moreover, there were many animals on the ground at that time, and the size of the animals was also very large, so these animals and plants would be buried in the ground because of the movement of the earth's crust in the process of crustal movement. In such a situation, it will be found that after a long period of geological changes, these plants and animals can gradually evolve into oil. Of course, there are some people who think that there were a lot of hydrocarbons underneath the ground in the past, and these hydrocarbons have undergone some changes due to the movement of the earth's crust, and gradually become oil.

Therefore, in fact, there is still a lot of oil extracted under the geographical ground, and the cost consumption caused by the different difficulty of exploitation is also different.

In fact, oil is a non-renewable energy source and will be consumed very quickly. Moreover, these oils also affect the direction of energy flow, so it is recommended to actively develop the use of renewable energy, such as solar energy, wind energy, ocean energy, tidal energy, these energy sources can actually be used by people at any time, and there is no need to worry about depletion. This is very important for the progress of a society's productive forces, and most renewable energy sources are clean energy, which will not have too much impact on the environment in the process of generation and consumption.

In ancient times, after the collective death of animals, large corpses were formed, and the putrid fat was mixed with the geology and squeezed to form oil. Because the size of dinosaurs in ancient times was very large, and there were many dinosaur groups, there was a lot of oil.

The process of formation is particularly long, generally evolved from the carcasses of animals or microorganisms, which has lasted a particularly long time, and the movement of the earth's crust is particularly frequent, because the history of the earth's existence is relatively long.

Oil is produced through a combination of biological precipitation and the movement of the earth, and the reason why there is a lot of oil on the earth is because human beings have been constantly extracting it.

Petroleum is formed through the continuous evolution of geological layers. This is because there is a lot of oil in the Earth's mantle.

The countries with the most oil in the world are:

1. Venezuela.

Venezuela is located in the north of South America, is a very oil-rich country, its oil volume has exceeded 300 billion barrels, although its oil volume is the largest in the world, but it is still a very poor country, because its oil is of poor quality and extremely difficult to extract.

2. Saudi Arabia.

Saudi Arabia is one of the countries with the largest oil reserves in the world, with the largest production and storage in the world, and has the world's largest road and offshore oil fields, with oil production reaching 266.5 billion barrels, making it a veritable oil powerhouse.

3. Canada.

Canada is the third largest country in the world in terms of oil production, and its oil is mainly distributed in Alberta, and its oil production is between 1697, in fact, Canada's oil production is very low, because its extraction is very manpower and financial resources, but its oil quality is very good.

4. Iran. Iran is the world's fourth largest oil producer, and its oil is mainly located in the world's most oil-gas-rich eastern region, with an oil production of 157.4 billion barrels, which has transported about 20 million tons of oil to China, and is also one of the richest oil countries in the world.

5. Iraq.

Iraq is located in southwest Asia, the oil industry is the spiritual pillar of the country, with its geographical conditions, oil and natural gas resources are very rich, its oil production is also abundant, about 142.5 billion barrels, is also one of the top ten countries in oil reserves.
