While some of the largest oil companies are "sleeping" others are working.
It is not at all true for all the big oil companies that they are more interested in buying back stocks than developing new technology.

Yes it is new technology we are talking about. Saudi Arabia and other lazy oil nations have traditionally only needed to throw a pick in the ground and up comes the black gold. It is natural for them not to invest in better technology or equipment.

I'll tell you a secret. Saudi Arabia buys our scrapped equipment and use it in their well drilling and exploration. Yes, they use the drill bits, tools joints and pipes that we no longer deem safe to use.

I can't speak for them or the companies in other parts of the world, but I know that here, we are not being lazy. Our involvement in the oil sector will benefit the world and we are soon if not already world leading on oil technology. Our innovations will make explorations and extraction cheaper for the world community.
Just take the oil sand in Canada. There is already technology that will make extraction easy based on the technology developed for extraction in the North Sea e.g. precision horizontal drilling.

USA is the largest oil consumer in the world and all though she is also one of the larger if not the largest oil producer it is not enough. USA consumes 20 million barrels a day (from memory) and produces around 8 if I am not mistaken. This means she needs to import the rest and oil nations benefit from this high demand. If you take a look at this map, you might notice that USA imports a substantial part of its oil from nations with problems. Take Nigeria as an example. They export around 1.6 million barrels a day to North America which is double of which other African oil nations do. Nigeria have problems with local terrorists or armed groups which destroys the oil pipes and makes it hard to deliver their daily load. This constant uncertainty of Nigeria being able to deliver contributes to higher oil prices for some reason.

Take a look at the map again. This is the nations that comprise OPEC, the organization that controls vast oil resources. They won't produce more oil as they do not agree that it is the demand for oil that pushes the oil prices up. They claim it is speculations, the low dollar value and USA's war in Afghanistan and Iraq (notice the use of USA exclusively). USA claims that the reason for high prices are that the demand is greater than the supply.

Notice how the slightly lesser demand in USA and Asia causes the current oil price to drop. Asian nations decided to drop its state funding of petrol and petrol consumers in USA find it too expensive to drive their car to the local store.

I don't know. I guess we would all benefit from a slightly lesser demand and a higher dollar value, but I think it is the scare mongers aka speculators that invent many crazy reasons for the oil price to go up, that is the major reason for the "crisis" we see today.
