Does anyone have a nice list of the top 10 (or even more if it's easy) fields and whether they are in decline or not. I don't know where to find that info.

Sweet! Thanks.

Now, not to be a PITA, but, do we know which of these are already in decline?

Absolutely fascinating. Thanks to those who compiled these lists!

[killJOY]

Hey, A_O, that list looks familiar.

Bet you got it here. Great oil site.

[smiley]

Number 8: Kirkuk is in decline

[Ludi]

I'm really amazed by those decline percentages! Where's that nice comforting 2% we were promised?

[smiley]

I think this is a nice idea. We should get this list as complete as possible. It might be very illustrative.

No 7 Ahwaz and no 9 Marun: Decline

$this->bbcode_second_pass_quote('', 'P')roduction of Ahwaz Bangestan oil field, for example, has fallen to 160,000 b/d from 250,000 b/d and will fall to 60,000 b/d within 1-2 years. A gas injection program could increase production to 220,000 b/d and maintain it at that level.

[grillzilla]

These three sites seem to confirm Marlim is declining, maybe at about 8%
especially the last one.

LMAO Sorry, I was away visiting relatives. Hang on and I'll update.

[Kez]

Where does China's big field fit in this list? I didn't see it listed. I thought it was the 4th or 5th biggest in the world?

"Daqing has 25,000 wells that produced 17.9 billion gallons of oil last year, about a third of the nation's total."

http://www.cnn.com/WEATHER/9808/17/chin ... index.html

By my rough calculations that's about 1.16 million barrels per day.

[MOCKBA]

$this->bbcode_second_pass_quote('Dreamtwister', '

[4dsc]

Are the estimates of the field size the real estimates or are they the inflated ones we got from the 1980?? I seem to recall the Kuwaiti's revised their estimates downward??

[Dreamtwister]

Upgraded #6 Tengiz and #13b Kashagan to "Additional production possible". Downgraded #15 Romashkino to "likely decline". Need more data on production rates to calculate decline.
