fractal distalation.... crude oil is placed in a "distailler and at certain temps certain products come off the crude. Lightest to heaviest. In the end you are left with a hodge podge of left overs ... tar

Could be he knows oil supplies are dwindling in Saudi Arabia where he has co-harts. Knew he had to do something to keep up his flow of money to himself and cronies based on oil production and trade. Somehow I think the Saudi's are in on this somewhere.

I do agree.  The presence of oil in the middle east has propped up medieval autocratic governments that would have otherwise fallen by the wayside.  The petro-dollars have given these government the means to basically bribe their populations without really serving them.  While some middle-easterners are ridiculously rich, the majority are in abject poverty (that is why Islamic radicalism is becoming so popular).  If you look, you will see that the radical Muslim movements are the most popular in the countries that are trying the hardest to restrict their people.

Another good clue is whether or not you are near a salt dome (i.e. cental and south Louisiana).  Oil is almost always found in the vicinity of these domes.

They are distributed based on where the specific minerals are located.  For example, the diamond industry is located in areas like South Africa where there are large diamond deposits.

The gold and diamond bearing Earth of Africa influences trade also its Northern fruitful savanahs are a reason its great population of animals and beasts also attract zoos. A bounty for smugglers and hunters is Africa. It is also rich in oil, herbal medicines snd vegetation. Logging also occurs there

Same reason.\n\nThe US wants control (influence) of the entire oil-producing region, so that they can ensure a regular supply.\n\nIt's not about individual countries.

because its a global world today and the oil prices have increased often globally.

The Niger delta is one of the largest oil production areas in Africa and hence has a big impact on the barrels produced per day in the region.The prices are dependant on the production form this area.

Ofcourse there is. The US oil wells are running dry now. Oil companies need to buy new wells and hence look for other geographical locations. Oil is the only reason for wars by US led in the Gulf or Asia.

oil forms when marine microorganisms (plankton) die and accumulate.  given the right amount of time (millions to tens of millions of years) and temperature (100-200C), they mature and become trapped below ground in the oil source rock.  this has nothing to do with the Earth moving off its axis.  all it means is that we know where to look for oil and we know that we're using it up far faster than it can form.

Aren't those two closely related? Political instability in the region is the leading factor in the high price of oil on the world market. With all this sabre rattling going on over Iran's nuke policy it's no wonder the price is up. I think the general incompetence of our Republican led congress (not to mention the level of corruption in ALL levels of government) and improving education in this country ought to be the real issues.

Few  processes on earth operate in isolation; areas on our planet are interconnected, which means linked to conditions elsewhere on earth. A condition, an occurrence, or a process in one place generally has an impact on other places. The exact nature of this interaction is not known. For example the presence of abnormally warm water off south Americas west coast (El Nino) seems to be related to unusual weather in other places in the world.
