After so many years of depletion of oil, why is the oil not only not decreasing, but more and more?
Oil is a fossil energy source and is non-renewable, which means that oil will be drained one day. In 1956, the famous geophysicist Marion King Hubbert (Marion King Hubbert) once mapped out A bell-shaped curve, according to which it can be found that oil production will reach a peak between 1966 and 1972, and then continue to decline until exhaustion.
According to industry reports in the early 1990s, the world's total oil reserves at that time were about 995 billion barrels, but by 2017, according to the data of the BP World Energy Statistical Yearbook (2017), the world's proven oil reserves Reserves have grown to 1,706.7 billion barrels.
And in recent years, there are fewer and fewer newly discovered oil fields. When the oil fields are exploited to a certain extent, the difficulty of exploitation will become more and more difficult, and the exploitation cost may even exceed the original price, so the exploitation has to be stopped.
Why is there more and more oil?
From the perspective of exploitation, the world's oil reserves are very large, but it is very difficult to extract. For example, the oil extraction rate in China is less than 30%. However, with the continuous progress of science and technology, the extraction technology, equipment and exploration technology are becoming more and more advanced. , those oilfields that are difficult to exploit may be re-exploited.
From the environmental point of view, the environmental problems caused by oil also need to be solved urgently. The excessive use of oil has brought about a very serious greenhouse effect. Countries around the world are vigorously developing new energy sources such as wind energy, water energy, solar energy, and nuclear energy. , its main purpose is not to deal with oil depletion, but to deal with the growing climate problem.
From the synthetic liquid fuel, we have mastered the method of converting natural gas into liquid fuel a long time ago, but the cost is very high. With the development of science and technology, the construction cost is getting lower and lower, but it has only been applied in recent years. In terms of industrial production and manufacturing, it has gradually entered thousands of households, and some oil resources have been saved, and there is no need to worry about the exhaustion of oil and the lack of energy for human beings.
To sum up: It is impossible for humans to run out of oil, and it is impossible for oil to be exhausted before human extinction.
