Can someone identify potential reasons for the oil prices rising?

Supply and demand... reduced supply coupled with the increasing demand for oil in emerging nations that in the past were less dependent on fossil fuels to power their transportation, industries and heating needs. Oil prices will continue to rise in the future since it is a finite commodity with and every increasing demand.Can someone identify potential reasons for the oil prices rising?

As more and more oil is taken out of the ground, only the lower grades or more inaccessible oil remains in the ground. These reserves were uneconomical to extract in the past because it was cheaper and faster to get to the higher grade oils and it all sells for the same price. Now these poorer quality deposits are all that remains so if we still want oil, they are our only choice. Methods to extract and refine these grades are much more expensive, so it follows that the price of the oil itself must go up.


Another reason is that Earths population is always increasing so the demand for oil is also increasing, hence prices go up. Theres big big bucks to be made in the oil industry so a lot of greedy people are attracted to it. If they want more money, they're gonna set prices higher. We need oil, and they know we need it enough to pay whatever they ask.
