Here's some charts based on the data in the International Petroleum Monthly just released last week. The data is through December, 2008 so we can get quarterly and yearly averages as well as the monthly.
First, the monthly. Apparently July, 2008 is holding it's own as the top month of oil production by about 500,000b/d over May, 2005.
Now the quarterly averages. The second quarter of 2005 holds its record as the most prolific quarter of oil production in world history 74,061 to 1q2008's 74,048
The plateau holds. I still think it's amazing that for 4 years world oil production has remained on a plateau within about 1 1/2 million barrels a day, even in the face of an incredible price rise.
And the yearly averages. 2008 seems to be the winner so far, pending further revised stats. Still not very impressive in the face of $100+ oil.
