Controversial statement. See the list of countries, TOP-10, by oil reserves:
1st place - Venezuela.
2nd place - Saudi Arabia.
3rd place - Canada.
4th place - Iran.
5th place - Iraq.
6th place - Kuwait.
7th place - United Arab Emirates (UAE).
8th place - Russia
The list doesn't make any sense. The cost of production of crude oil in Saudi Arabia is only around $9 per barrel (that includes transporting the crude to refineries). For Russia it costs around $30 to produce one barrel of crude from the onshore deposits (including transport). For the arctic reserves, the production cost excluding transport is $120 per barrel. So it is not right to group all the deposits together. It may give an impression that Venezuela will benefit the most in future, but the cost of production there is manytimes what they have in Saudi Arabia.
You misunderstood the key point a little - I wanted to say that the income received from one and the same resource (oil, even with a different cost price) cannot always be used wisely! Whatever the cost of production in the Russian Federation, for the period from 2000 to 2018 the budget of the Russian Federation received several trillion dollars !!! (sources are readily available in the public domain) For that kind of money, the country could implement a huge number of projects within the country, raise the standard of living, and at least gasify the houses of its citizens! If you don't know - in the Russian Federation, being the largest gas supplier to the world market, more than 40% of the residential sector is not supplied with gas! They could also develop a technological niche, at least follow the path of purchasing technologies to create a foundation for further growth. But all they did was a pitiful parody of Silicon Valley - Skolkovo, where hundreds of billions of rubles were stolen. The output is nothing significant or deserving minimal attention. During this period, no new schools were built, but their number, on the contrary, decreased! At the beginning of 2000, there were schools in the Russian Federation: 46 thousand, now, in 2021, it has decreased to 24 thousand! Medicine fell into decay, and the reforms turned out to be a failure - the number of medical institutions and the quality of their work significantly decreased! The retirement age was increased, social funds were reduced.
But for example, Norway in recent years has created the National Welfare Fund of Norway. With reserves of over 1 trillion EURO! No, they didn’t set up palaces all over the country for their president, they didn’t surround themselves with a half-million, tame, national guard, to protect themselves from their own people!
And the United Arab Emirates, over the past decades, from desert settlements have turned into the most technogenic and developed megacities! At the same time, they invest this money both in the population and in the technologies of the future!
And in the state of Alaska, every citizen of the state receives an annual supplement from the sale of oil, and part of the funds goes to the development of the state's infrastructure ...
I'm sure this will make the main idea that I wanted to convey clearer?
Well, about prices, production costs.
I agree that Saudi Arabia has the lowest production cost. But in Iran and Iraq, it does not differ much - $ 9 and $ 10.5 per barrel - so what? Is it also wonderful to live there like in Saudi Arabia?
But in Norway it is generally $ 30 / bbl. and the most difficult conditions for offshore oil production! Can I tell you about the quality of life in Norway?
By the way, I disagree on the estimate of the cost of oil production in the Russian Federation - your data is greatly overstated! Official data in Russia - the weighted average cost of production is about $ 18 / bbl, or from $ 9 to $ 20, depending on production sites and infrastructure. This is according to the official statements of the Deputy Head of the Ministry of Energy of the Russian Federation, Pavel Sorokin, in 2020, which you can easily check in open sources ...
