Reserves

• U.S. proved oil and condensate reserves totaled 21.317 billion barrels (bbls) in 2007, up 1.6% from the 2006 figure. The 2006 number had fallen 3.6% from the 2005 figu re, which had risen 1.8% from 2004’s level.
• As of 2007, the top 10 states/areas for proved gas reserves in the U.S. include Texas (5.122 billion bbls); Alaska (4.163 billion bbls); California (3.322 billion bbls); the Federal waters of the Gulf of Mexico (3.320 billion bbls); New Mexico (735 million bbls); Wyoming (690 million bbls); Oklahoma (530 million bbls); North Dakota (482 million bbls); Louisiana (458 million bbls); and the Federal waters of the Pacific (441 million bbls).
• U.S. proved oil reserves are now at 55% of the all-time high of 39.001 billion bbls in 1970.
• According to the U.S. Dept. of Energy, significant increases in oil reserves occurred during 2007 in North Dakota (+17.0%); Colorado (+10.9%); Alaska (+7.5%); Louisiana (+7.0%); Utah (6.3%); Texas (+5.2%); and New Mexico (+4.3%).

Production

• In 2008, the U.S. produced 4.956 million barr els per day (bpd), down 2.2% from the 2007 figure. However, if not for a brief disruption in September caused by Hurricane Ike, the 2008 average would have increased from 2007’s level. Previously, U.S. output was down 0.7% in 2007 and 1.5% lower in 2006.
• At current output rates, the U.S. has about 12 years of production available from existing proved reserves.
• The top 10 oil-producing states/areas in the U.S. during 2008 included the Federal waters of the Gulf of Mexico (1.2 million bpd); Texas (1.1 million bpd); Alaska (688,000 bpd); California (587,000 bpd); Louisiana (203,00 0 bpd); Oklahoma (172,000 bpd); North Dakota (167,000 bpd); New Mexico (162,000 bpd); Wyoming (147,000 bpd); and Kansas (108,000 bpd).
• Across the U.S., the number of actively producing oil wells during 2007 was 525,287, up 5.0% from the 2006 figure.
• Over the last 20 years (since 1989), the number of U.S. gas-producing wells has fallen 13.4%.
• During the last 20 years, average oil well productivity has fallen 25%, to 9.4 bpd per well.

Consumption

• U.S. oil consumption (total products supplied) in 2008 was 19.419 million bpd, down 6.1% from the 2007 figure. Most of this decline can be traced to the deep recession that began in the back half of 2008. This was the lowest oil usage average since 1998’s 18.917 million bpd.
• About 51% of finished petroleum products in 2008 were accounted for by motor gasoline. The next largest share (23%) was taken by distillate fuel oil, followed by kerosene-type jet fuel (9%).

For transportation purposes, California (615,649 bpd) led the nation in total petroleum consumption during 2007, followed by Texas (512,376 bpd); Florida (296,000 bpd); New York (194,083 bpd); Illinois (193,091 bpd); Ohio (188,757 bpd); Pennsylvania (182,120 bpd); Georgia (171,387 bpd); Virginia (148,820 bpd); and Michigan (144,401 bpd).
