Slope production drops faster than estimated

Slope production drops faster than estimated
State officials say their overestimating could hurt budget plans

$this->bbcode_second_pass_quote('', '
')Alaska North Slope oil and gas fields declined 12.5 percent in production of crude oil and natural gas liquids last year, according to an analysis by the state Department of Revenue.

North Slope average daily production in state fiscal year 2007 was 738,000 barrels per day, down from an average of 844,000 barrels per day in the previous year.

The drop in production is higher than estimates by both industry and the state. The state makes long-term production forecasts as part of its twice-yearly state revenue forecasts. Royalties and taxes from oil production pays for 85 percent of the state budget.

Part of the decline was due to the Prudhoe Bay field's partial shutdown for several weeks in 2006 after BP experienced leaks in corroded pipes. The decline was also partly attributed to weather conditions at the Valdez Marine Terminal in November that impeded tanker loadings, the analysis shows.

But the data also shows a steepening of the natural decline of the large, older fields on the Slope, rates that exceeded estimates by the producers and the state.
....
The Prudhoe Bay field, which suffered a partial shutdown in August and September 2006, showed the most dramatic decline in total annual production, a drop of 19.4 percent, according to the analysis. Prudhoe is the largest field in northern Alaska and accounts for roughly half of total North Slope production.

The Kuparuk River field, the second largest field, showed an 8.8 percent decline. Endicott, an offshore field that started production in 1987, showed a 20.2 percent decline. Alpine, a relatively new field that began in 2000, showed a decline of 14.8 percent. Production from small satellite fields near Alpine has keep the field processing facilities at maximum capacity.

But a 2% world decline rate is perfectly reasonable...

I think a 2% world decline rate is wishful thinking. Every field is declining "faster than estimated" or "faster than expected". That doesn't bode well for a shallow slope on the right side of Hubbert's curve.

Yes.

The assumption that the right side of the curve will even remotely resemble the upside is completely irrational thinking. Advanced drilling techniques and all.

Even if the world decline rate is around 2-3%, the decline in exports will be much higher, at least from those areas where the oil is state-owned. It is usually only excess production, above domestic use, that is exported and that proportion will be the one to feel the decline rates.
Kind regards, Katkinkate

If you don't mind me asking? Where did the chart above come from? Is it your chart or was it out of some report? Has it been peer reviewed?

And why does it jump from a 1% decline to a 4% decline without passing through 2% or 3% ?

Slope is harder than expected especially if you consider EROEI. There is no information about it in those charts. I think that the second part of Hubbert courb regarding world oil production will more likely look like a cliff. (Note that i didn't mention politic as was said above)

Address in the graph is for the article Updated World Oil Forecasts, including Saudi Arabia from last week. That article doesn't contain this chart, however.

Cantarell is 20% and North Sea is 14%, innit? So 17% between the two of them, those are the headline grabbing catastrophic declines we're pulling our hair out over.

Unless you're factoring in Ghawar, which some say is crashing now as well...

These rates of decline, along with the Export Land Model and the likelihood of dramatic export cuts dues to growing domestic consumption are what scare the hell out of me.

If this doesn't make your view of the future more doomeristic, please tell me why not. I really need some straws to clutch onto. :(

I have to agree with the common sentiment here. Every time I see a projected decline rate it's around 4%, and reports of actual decline rates are in the 10-15% range... It's time for those cockeyed optimists to wake up and smell the coffee!

Alright, the Saudis say they can increase production on into the next couple decades, ever since they revised their reserves in the 80s. You don't really think the politicians of the last 20 years have been merely naive to believe them, do you? No one's ever questioned them about this, they must know something we don't, right?

Right?

Right?

It's only part of the problem. Take Kuwait, building 2.5 GW of power capacity next year, planning to run it on oil. After halving their claimed reserves and by default coming clean about 1985 and all that, is Kuwait going to lift production to compensate for the implied loss of exports? Unlikely. Is KSA going to selflessly add that burden to the West's annual wish list? Unlikely.

I think yes, the global decline rate will be a lot higher than 2%. In fact, I don't know who is still predicting 2%. Campbell was saying 3.25% back in the mid-1990s, Bakhtiari suggests 5% these days. Once we are off the slow turning point, that is what we are realistically looking at.
