Posted: Thu Jun 23, 2005 8:08 pm Post subject: Saudia Arabia has 68 Years of Production at 2004 Levels ?? |
|
|
Can someone help me understand how this chart from the economist, which shows that Saudia Arabia has 68 years of oil reserves at current production, and several others have over 70 years of production at current rates, compares to the work of peak oiler modelers who say peak world production is near? I mean, I understand that the demand will increase over time rather than staying at 2004 levels, but 68, 100+ etc. years of production at current levels? This seems so far off from what some others are saying it's very difficult to make sense of.

three things off the top:
1. they are assuming no growth..which never works
2. they are assuming that we'll get every drop, and maintain current levels of production, which doesn't happen due to pressure loss and water cut
3. they are economists |

oh and..
4. we have to believe their 'proven' reserve 'estimates'
personally, i don't see how an estimate is also proven.
it's sorta like saying, “well mr. president, the Apollo 13 mission is estimated and proven to last 10 days. We launch in t – 10 seconds.”
but hey, whatever keeps those investors happy...  |

There are specific rules ....adopted from suggestions by the SPE regarding what constitutes proven and probable reserves. Proven reserves are expected to have a 90% confidence level that under current economic conditions they will be produced. For most North American companies who are governed by SEC or OSC these reserve figures are audited....new rules suggest certain percentages of reserves which must be audited each year. The big issue is that Saudi Arabia has no one to answer to with respect to their reserve calculations and reporting. As a consequence we have no way of knowing what is proven or probable. The Saudis say they have X and Simmons says they probably have much less than X. Simmons book raises important points but without the data noone can claim to know the answer. |

also the Economist published this
take from that what you want.
you can get to it by taking their 'green quiz' |

The problem with the reserve/production ratio as shown in the chart is that it is a static snapshot in time and doesn't reflect the changing dynamics of growth in demand, degree of depletion or anything else. It means that if all those reserves existed and were exploitable, you could produce them for that many years at current rates of production, and in years+1 there wouldn't be a single drop left.
Geology doesn't work that way.
Remember, peak oil is only the half way point. Saudi, Kuwait, Iraq, Iran will continue to produce oil for many, many years (perhaps not as long as shown here, but certainly many many years). But what matters is the global total. If we only have 30 mmbd of Middle East oil producing in 20 years when demand today is 86 mmbd, then you can see the problem. There's lots of oil left--a trillion or more barrels, but it's not as cheap, not as easy to extract, doesn't have as high energy profit, and IN AGGREGATE, won't be produced in volume higher than what the peak is. And when it stops growing, our paradigm crumbles. |

Yes but the R/P ratio gives an indication of how fast reserves are being produced. Given that most OPEC countries have R/P above 50 years and non-opec has R/P around 15 I have a hard time seeing how OPEC can be at peak as many here claim. OPEC was ramping up rapidly before the 70's oil shocks after which a lot of production was shut in.
Unless of course the reserves figures are complete crap. |

Here's how i see it. Saudi Arabia reports reserves at 262 billion barrels. However they themselves admit that only 130 billion of these are proved while the rest are just probable.
Another constantly brought up argument is than in the 1980's most OPEC countries raised their reserves suddenly by large amounts, some like Saudi Arabia and Kuwait almost doubled their reserves overnight. This data is ther at the ASPO website. Since OPEC quota's are determined by size of reserves, many experts believe that these reserves were spurious ones to gain additional export shares. Another point is that there has been little change in OPEC reserve estimates since the 1980's. For example the Saudi's have reported around 250 billion barrels since 1985 or so although in the meantime hundreds of billions of barrels have been pumped out of the ground throughout the middle east. This essentially is the argument of the critics of Saudi Arabia.
Matt Simmons brings up the issue that 90% of Saudi Arabia's oil production is from 5 mature fields all discovered in the 40's or 50's. His main argument is that the Saudi's may have overworked these fields (water injection and other methods) and these fields may face a sudden collapse and a rapid decline. These issues are complex and considering the secrecy with which the Saudi's guard their reserve data it is difficult to decide where the truth lies.
If the Saudi's are telling the truth it might be possible theoretically for them to sustain their current production for 50 years, but there are reasons to be extremely worried. |

| As far as production, actual annual production, are these good numbers? Who provides data on actual production? Is it possible that some of the actual production numbers could be off? For instance, after it was determined a couple of years ago that Saudi Arabia's annual production had declined a bit (then jumped up again) is there any way that they or someone could have artificially inflated production numbers? Anyone know? |

Read the following which may clearify a few things.
http://www.energybulletin.net/333.html
If consumption continues to grow then it will not be possible to satisfy it by the supply. We did not go into Iraq for Democratic reasons.
If Saudi could deliver all that we need we would not be in Iraq. _________________ Men argue, nature acts !

Economist view: Saudi Arabia have 262.7 Gb left, they produced 10.6 mbdp in 2004:
262.7 Gb / (10.6 * 365 / 1000)= 68 years
Woa! plenty of oil left! no problemo!
but, a few problems:
- they assume implicitly a rectangular production curve as a model (68 years wide by 10.6 mbpd high).
- no increase in demand
For an economist mind, a rectangular production curve is great but for a geologist it is an outrage because it means there is no depletion! you take what you need without physical constraints!
The reality is:
- the production curve is a smooth unimodal curve with a maximum production rate and afterward a depletion. It means that you have to make a compromise between field sustainability (I produce for a long time) and field productivity (instantaneous production output). The more I push productivity (ex: enhanced recovery) the harder is the fall (because I have always the same area (the URR) under the curve).
- demand has to increase just because population is increasing
conclusion: by trying to be simple and concise, economists are missing (or hiding) the real problem: depletion _________________ ______________________________________
