I don’t feel like holding hands, but to give you an idea of magnitude (lightly edited from above):
Note substantial percentage of OPEC imports are Venezuela. Not a substantial improvement over the Mid-East in many respects.
US proven reserves are declining and are higher extraction cost than existing proven reserves in other areas.
No.
Petrol is a global commodity. Total demand (excepting some near term barriers due to refinery set up / optimization) is what counts. Saudis btw sell at a discount to the US in order to keep market share on the (correct) belief that most folks are too economically illiterate to understand the dynamics of the market.
US btw is the largest single market, our demand is the single largest component. Think that through.
Small percentage, the issue however is the global market and total demand, not what % is directly sold. This is one of the most well-developed and liquid commodity markets around.
Sounds like it might be right. Go to the International Energy Agency for further information and data, although the DOE site is quite rich as well.
