Not an expert, but pretty knowledgeable, so here goes.
The GS and Boone Pickins statements about $150-200/bbl. oil comes from the following FACTS.
-The world currently has the ability to produce somewhere around 85-86M bbls of oil a day; and the world currenly consumes about 83-84M bbls of oil a day. Meaning there is only about 2M bbls of spare capacity and any supply disruption (instability in Middle East, Nigeria, etc), and the market is in the Negative.
Current growth trends in the world economy (think China, India), call for an increase in demand for oil of about 4-5% per year, and current growth in supply (increase in production) of oil going forward is about 1% per year. So, the growth of oil being produced is very Very likely NOT going to keep up with the growth in Demand in the future years (at least 1-5yrs out).
The Saudis do have about 2M bbls of extra/spare capacity available; however, most of that crude is 'heavy sour crude' which is very expensive to refine, and further there are few refineries that have the capability to refine it.
Off the U.S. east coast (the outer continental shelf) there is an estimated 20-40 Billion Barrels of oil, and even more, there is Billions of cubic feet of 'clean burning' Natural Gas. WE, thanks to Congress and 'special interests' in the this Country, completely refuse to drill for it. ALL of the Oil Executives before congress yesterday, all said, open up these areas for us to drill for more oil here, Domestic Production. In the future, we will be paying $7-9.00/gal. for gas, and probably still refuse to develop our own oil reserves.
All our 'so called' leaders (and future so called leaders) keep talking about is "Wind and Solar" which are good future resources and should be employed to add to our future needs. However, my car does NOT run on Solar power and Doesn't have a Sail.
O.K. so I've gone on long enough. Hope it helps, for what its worth.
