Most geologists believe that oil, like coal and natural gas, is gradually formed by long-term compression and heating of ancient organic matter. According to this theory, oil is formed by the changes of prehistoric marine animals and algae corpses. In fact, this assumption is not true, because even if all the living things on the earth are converted into oil, the oil production is too different from the proven oil reserves on the earth.
The distribution of oil reserves is uneven, and the main oil-producing area in the world is the Middle East. Because what is produced in any place is also regular. There is generally no oil in the ground where crops can be planted; Where there is oil, it is often a barren land like the Middle East. After millions of years, the land has formed such an unbalanced landform, so the resources produced are unbalanced.
The topography of the Middle East belongs to the junction of plates, which provides an important material basis for the formation of oil. At the same time, compared with other regions, the Middle East is relatively low, forming a basin state, which also makes it easy for oil to accumulate in it. In addition, the surface of the Middle East is closely covered, and it is not easy to leak and volatilize. These three factors are also the reasons why the Middle East is rich in oil. But there is still no completely reasonable explanation for the real formation of oil.
According to the data of 20 19, Saudi Arabia, the largest country in the Arabian Peninsula, has oil reserves of 266.5 billion barrels, accounting for 16% of the world's proven reserves, ranking second in the world, and Venezuela, the number one, has 296.5 billion barrels, 30 billion barrels more than Saudi Arabia. However, proven reserves and recoverable reserves are different, and some places are not worth large-scale mining because of cost and technical reasons. However, most of the large and super-large oil fields in Saudi Arabia were discovered between 1936- 1970, and no new oil fields of comparable scale have been discovered since then. Therefore, the implied increase of reserves must come from the improvement of the prediction of existing recoverable reserves.
At present, the production situation and recoverable reserves estimation of various oil fields in Saudi Arabia are state secrets, and only a few insiders know how many there are, so there are different opinions. In the crude oil market, professional oil market analysts generally do not predict the rising and falling trend of crude oil by predicting when Saudi production and reserves begin to decline. At present, Saudi Arabia produces more than 6.5438 billion barrels of crude oil every day, about 4.5-5 billion barrels a year, which can last for 60-70 years according to the proven reserves.
However, according to the internal analysis reports of many investment institutions on Wall Street, it is generally believed that Saudi Arabia will run out of oil in about 20 years. In recent years, the Saudi government is also worried about the current situation of extreme dependence on crude oil, worrying about the situation like Venezuela. Saudi Vision 2030 put forward by the government in 2065438+2006 has carried out comprehensive reforms in politics, economy, culture and society. Economically, it is easier to weaken the dependence on crude oil exports and develop diversified economies, including 2065 438+09 Saudi Aramco IPO, which provides financial support for economic transformation and aims to improve the economic structure. But it is not easy to change in a short time, and the effect seen in recent years is not ideal.
This is mainly because of the great correlation between oil and the US dollar, and Saudi Arabia must follow the global strategy of the United States, including the fact that the pricing and supply of oil are actually affected by the strategic interests of the United States. The United States does not want Saudi Arabia to get rid of the situation of relying solely on the oil industry in order to better control oil resources and maintain the international economic and trade system centered on the US dollar. For example, Biden recently reformulated the Middle East strategy after taking office. While pushing up oil prices, on the one hand, he eased the relationship between Yemen and Iran, which are hostile to Saudi Arabia, on the other hand, he brought up the murder of political opponents by the Crown Prince two years ago to beat the Saudi government.
Oil is a non-renewable resource. Many people worry that if oil is used up and there is no oil available, many oil-using machines will not work normally. Isn't it impossible for a machine that works on oil to operate normally?
In addition, for example, most of the vehicles we often use are driven by gasoline. Can't cars move without oil?
I have to say that this worry is still necessary, so we must plan ahead.
So, how much oil has been discovered on the earth now? How long can proven oil be used by human beings?
In fact, many experts have already calculated this problem.
At present, the known world oil reserves are10.7 trillion barrels, and Saudi Arabia's oil reserves are not ranked first.
In fact, we know Venezuela, and most people know it through the United States, because the United States has many complaints about this country!
There have been few wars with Venezuela. Venezuela is not like Saudi Arabia, which is like a subsidiary country of the United States. So the United States is still very interested in Saudi Arabia.
Of course, the United States can get more benefits from Saudi Arabia.
Generally speaking, the United States will intervene in countries with large oil reserves, and eventually these countries will listen to the United States. Venezuela does not want to listen to the United States, so they have always been hostile to the United States!
Since Venezuela has the largest oil reserves in the world, what is the oil reserves of their country?
So far, Venezuela's proven oil reserves are 303 billion barrels.
Saudi Arabia's oil reserves rank second in the world, at 297 billion barrels. In fact, they are only a little less than Venezuela. But Saudi Arabia's oil production is definitely the highest in the world at present.
Canada 654.38+06.7 billion barrels, Iran 654.38+05.5 billion barrels and Iraq 654.38+04.7 billion barrels.
Other countries also have it, but the number is not too much.
So, how long can these proven oil reserves in the world last for mankind?
Soviet experts estimate that human beings can use it for another 50 years. However, it must be clear that this 50-year period is to find out the oil reserves.
In fact, there are many countries that may have more oil reserves, or people find that there is no foreign report at all, so just remember the rest.
In short, there must be a lot of oil reserves.
At least Saudi Arabia still has a lot of unexplored oil reserves. Now people are not in a hurry. Let's use the proven ones first.
Therefore, the proven oil reserves at present may only be 9 Niu Yi Mao. At least our generation and even the next generation hardly need to worry about running out of oil.
There are many diamonds in the world, but people don't develop them, only a little each year, just to ensure the price of diamonds.
In fact, oil is similar to diamonds, and things are rare. Only when the reserves are small can they be sold at a high price. Therefore, the world's oil reserves must be much larger than those currently proven. Don't forget that three-quarters of the area is ocean, and there may be a lot of oil reserves under the ocean.
In short, we basically don't have to worry about this. We can use it whenever we need it.
Saudis are very proud and give people a lot of money every year. What we know is that they are a very rich country. They are rich because they have a lot of oil.
Without oil support, Saudi Arabia estimates that eating is a problem.
As we all know, the hinterland of Saudi Arabia is basically desert and its industrial base is very weak. If so, Saudi Arabia will not be proud without oil.
Many people are concerned about whether Saudi oil will run out. If mining is carried out at the current rate, how many years will it take to complete?
At present, the proven world oil reserves are10.7 trillion barrels, and Saudi Arabia ranks second in the world.
Do you know where the country with the largest oil reserves is?
Venezuela!
Venezuela has proven oil reserves of 303 billion barrels, ranking first in the world.
Saudi Arabia's oil reserves are 297 billion barrels, ranking second in the world.
Canada 654.38+06.7 billion barrels, Iran 654.38+05.5 billion barrels and Iraq 654.38+04.7 billion barrels.
As for Saudi oil, how long will it take to run out?
According to their current mining progress, it can still be calculated. At present, Saudi Arabia produces130,000 barrels of oil every day, reaching 4.7 billion barrels a year.
If we continue to mine at this rate, Saudi Arabia's recoverable reserves will be exhausted within 56 years.
In other words, the prime time for oil in Saudi Arabia is still more than 50 years.
However, we must be clear that this is the known reserve of Saudi oil, and it is believed that there is still more oil in Saudi Arabia that has not been exploited. In other words, it is impossible for most of us to see Saudi oil being exploited in our lifetime.
Maybe there is more unexplored oil under the desert in their country.
In fact, many countries in the world have long been discussing how many years oil can last.
Russian media previously reported that oil can be used by human beings for another 50 years.
Of course, this also means that the proven oil reserves can be used for more than 50 years. In fact, there are still many oil reserves, which may not be proved.
Is there an oil reserve in the deep sea?
This is not clear at present. In short, every country with a lot of oil is not worried about this problem. Their greatest concern is to exploit the discovered oil and sell it. After all, oil is underground. If you don't exploit it, it may flow to and be exploited by neighboring countries.
Of course, many people are worried about what to do when the oil runs out.
As we all know, countries worried about oil exhaustion are now considering replacing oil with new energy. Whether it can really replace oil needs to be studied.
In short, at present, 50 years may not be enough. Maybe more oil will be found in these 50 years.
In short, our generation will never see the scene of Saudi oil running out.
