447. New BooksThe library of books on oil depletion, peak oil, and its dire impact grows rapidly, as awareness reaches many sectors of society. The following additions may be noted:
448. Further Study on Saudi ArabiaThe following analysis by John Lyles presents a logical review of the Saudi situation. Recent presentations by Saudi Aramco Representatives and a review of the technical literature allow the construction of the following table showing the evolution of Saudi Aramco reserves, Oil Initially in Place (OIIP), and recovery factors.
Saudi Aramco often compares the proved reserve estimates for 1975 with the current claimed proved estimate of 260 Gb. This is misleading as, by the definition of Probable and with the passage of time and production experience, surely most of the 1975 Probable would by today be expected to be re-classed as Proved. One should compare Proved plus Probable (2P) reserves and recovery factors. On this basis, the claimed 2P recovery factor has been increased by about 50 % (from 38% in 1980 to 56%). Some elementary maths and petroleum engineering knowledge are sufficient to demonstrate that new discoveries cannot be important in this increased recovery factor. It must pertain almost totally to the pre-1975 reserve base. The amount of technical data available on Ghawar allows one to construct both an independent view of its reserves and a very good estimate of current Saudi Aramco claims. Estimated cumulative production from Ghawar is 54 Gb, and the remaining proved reserves are about 60 Gb (a total of 114 Gb) with another circa 10 Gb as Probable, giving just over 200 Gb Initial Oil-in-Place. (These numbers are fully consistent with the comments of Dr. Afiffi of Saudi Aramco during his recent AAPG lecture tour.) A 1975 Proved & Probable (2P) estimate for Ghawar is not in the public record, but one can make an educated guess. If Ghawar had the same percentage of the 1975 Probable of 67.7 Gb as it had of Proved (46%), then the Aramco 2P Reserve estimate would be 91 Gb. In fact, this is likely a conservative estimate. Inspection of the table above, knowledge of the Saudi field size distribution, and the history of Ghawar Proved Reserve bookings (disclosed by Dr. Saleri of Saudi Aramco for the northern part of the field) all constitute powerful circumstantial evidence that this assumption is approximately correct. On this basis, Ghawar could have accounted for at most 35 Gb of the roughly 200 Gb in 2P Reserve additions since 1975. (Of further interest is that a similar exercise can be done for Abqaiq which suggests that its 2P Reserves have expanded by about 4 Gb from 1975 to 2003, or about 30%.) This implies that the recovery factors in the other large fields in the reserve base have been increased substantially more than for Ghawar, and that the 2P Reserve estimate for Ghawar was reasonably accurate, given the modest production history and zero water cut up to that time. This raises further questions about Saudi Aramco claims that the original 1975 reserves estimates were ridiculously conservative. Based upon the conclusions of this analysis, Ghawar can be excluded from the current OIIP and Proved Reserve numbers. Exclusive of Ghawar, Saudi claimed OIIP is 500 Gb and remaining proved reserves of about 200 Gb. Surprisingly, excluding Ghawar does not have a significant effect on the aggregate recovery factor. Excluding Ghawar, the 200 Gb of Remaining Proved Reserves are 18 % depleted. After removing the estimated remaining Ghawar Reserves from the 131 Gb Proved Developed number, only about 70 Gb, or 35 %, is developed. Of this 18 % depletion, about half is accounted for by only two fields (Abqaiq and Safaniyah, which have produced over 20 Gb). Of the entire 85 or so recognized Saudi fields, only about a dozen have ever been produced, and only 5-6 have produced significant quantities. We may ask if a 50 % Recovery Factor, combined with such a high proportion of Proved and low proportion of Probable (roughly 90/10) is credible, either in the abstract or with reference both to the low state of depletion and the high percentage of undeveloped reserves. The Association for the Study of Peak Oil, Wood Mackenzie, and PFC Energy consultants, all estimate remaining Saudi reserves in an order-of-magnitude of 150 Gb. The U.S. Geological Survey (USGS) estimates about 180 Gb in its study of 2000 based on IHS data. While reserve estimates are properly based upon technical factors and production history, the conclusions must make sense when compared with historical experience. The above analysis is much more consistent with these lower estimates than Saudi Aramco claims. The thrust of above analysis seems to be confirmed by the following press report from Dow Jones
449. Country Assessment - CanadaCanada is the second largest country in the World covering some 10 million km2. The central plains and lakes overlying the Canadian Shield are flanked to the west by the Rocky Mountains and to the east by an older Appalachian chain, while to the north is an archipelago of Arctic Islands. It has an extensive common border with the United States, and is flanked to the northeast by the autonomous Danish territory of Greenland. It is a very sparsely populated country supporting no more than about 30 million.
The earliest settlers crossed the Bering Strait from Siberia at the end of the Ice Age, more than 20 000 years ago. In the 9th Century came the Vikings, who established a few small settlements, to be in turn followed in the 15th and 16th Century by British and French fisherman attracted by rich catches off Newfoundland. In 1534, the French explorer, Jacques Cartier, made his way up the St Lawrence River to reach the sites of what are now Quebec and Montreal. Settlers followed developing the fur trade, later supported by the French Government wishing to incorporate Canada into its Empire. The Jesuits also arrived with the intent of converting the indigenous population. British commercial interests likewise appeared, partly expanding northwards from colonies in America, which led eventually to armed conflict, echoing contemporaneous wars in Europe. The American Revolution and secession brought further conflict and confusion, but British control was progressively established, leading in 1867 to the formal declaration of Canada’s Dominion status within the British Commonwealth. The extermination of the bison, on which the indigenous people depended, led over the years to their decline to less than 2% of the present population. Their lands were also expropriated as railways were constructed to open up the western lands to European settlement. French-speaking Quebec remains as a somewhat less than fully committed province of the country. The Klondike Gold Rush of 1896 drew attention to the mineral potential of the North, which was followed by the discovery of massive deposits of iron, copper, lead, zinc and other minerals in the ancient rocks of the Canadian Shield. The prairies too were opened up as a rich source of wheat. The resulting economic prosperity encouraged further settlement and immigration such that the population increased six-fold from about 5 million in 1900 to its present level. Canada supported Britain in both World Wars, with its forces playing heroic roles in several battles. Oil exploration commenced in the early years of the 20th Century without significant result until 1947 when the Leduc Field was found in a Devonian reef in Alberta, by which time some 250 wildcats had been drilled. Most of country is made up of non-prospective rocks of the Canadian Shield, with the prospective tracts being mainly confined to the foredeep of the Rocky Mountains, the Atlantic margin, and the Mackenzie Delta in the Arctic. It is not at all easy to evaluate Canada’s oil position in international terms because of its particular commercial environment and reporting practices. First, it has an exceptionally high cutoff for heavy oil at 25o API, because of the flow constraints imposed by the cold climate. Second, it has a highly fragmented industry, such that the term wildcat is generously applied, partly for tax reasons. It has huge deposits of bitumen and extra-heavy oil from which synthetic oil is made, and lastly much of the country lies within the Arctic Circle, whose oil is here excluded from what is termed Regular Oil. Much more study is needed to unravel the statistics, with this assessment being no more than an approximation. The Western Canadian Sedimentary Basin, lying mainly in Alberta, is the prime oil province, but is now at a mature stage of depletion so far as Regular Oil is concerned. The Atlantic Margin off Newfoundland has been developed over the past two decades delivering the giant Hibernian Field, with about 700 Mb, but is also approaching maturity. A third province is the Mackenzie Delta and Arctic Islands which are predominantly gas prone. Hopes for new discovery off the Pacific Coast are likely to be dashed as this is not a prospective regional setting. Canada is a net importer of Regular Oil, and its needs are likely to grow as depletion progresses unless its demand can be cut. Substantial deposits of heavy oil and bitumen, mainly from so-called tar-sands, occur on the eastern margin of the Alberta Basin, having been formed when oil from various source-rocks within the basin migrated to be weathered and attacked by bacteria at shallow depth. Extraction is effectively a mining process, involving the removal of up to 75m overburden. In addition are various drilling methods involving steam injection. A new technology based on catalysts is showing promise. The size of the resource is enormous, but it is not an homogenous deposit being subject to many subtle but important variations in oil and reservoir character. So far, only the more favourable sites have been exploited, meaning that future developments will be ever more difficult. Another constraint is the fuel needed to run the extraction and processing, much currently drawn from rapidly depleting stranded gas fields. Large amounts of water are also used, causing the Albertan government to express concern about depletion of the aquifers. It is a costly process with a low net energy yield. Many operators have faced budget over-runs, but new interest is being attracted as oil prices soar. Production, including derivatives, is here estimated to rise from about 1 Mb/d to-day to a plateau at 2.6 Mb/d starting in 2020, in a slow, labour- and capital-intensive process, also carrying environmental costs. This may prove to be an optimistic assessment because, as mentioned, the local gas used to fuel the plants is in decline, and it may be more economic to use new gas from the Arctic directly as gas rather than to produce these difficult liquids. If the World faces a deep depression due to the soaring price of Regular Oil, and a collapse of the stockmarket, that might also cut the demand for the tar-sand products, which will remain relatively expensive. On the other hand, it is possible that the US government may invest in a nuclear power plant to provide the needed energy on the grounds of national security, but again that might be better used as a direct source of electricity. Canada has substantial gas reserves, especially in the Arctic. Approximately 195 Tcf have been discovered, of which 134 Tcf have been produced, leaving estimated reserves of 60 Tcf. They are currently being depleted at a rate of 6.4 Tcf/a, of which 3.3 Tcf/a are exported to the United States. Future discovery is here tentatively estimated to be about 25 Tcf, but it could be higher. Canada unwisely signed up to the North American Free Trade Association, allowing its resources to be drained by its neighbour. Its inhabitants may accordingly soon have to freeze in winter to keep the hairdryers of Houston going. It is reported that a new impetus to further reduce the barriers under NAFTA-Plus is under active consideration between the three governments, premised again on the pretext of “homeland security”. Under such pressure, it would be is easy to forgive the citizens of Quebec if they were again to seek their independence. 450 Buying Oil is easier than Finding ItThe following article puts it well: www.dailyreckoning.com Cosmic Easter Eggs By Eric J. Fry
(Reference furnished by Kellia Ramares ) 451. CNN Relays ASPO’s Message on Peak OilCNN carried the following article on its CNN-Money site, deciding to delay publication until after the election. The original included a reproduction of the graph of declining discovery at the beginning of the ASPO Newsletter, contrasting it with the EIA Scenarios, based on the USGS range, but assuming an absurd 10% decline after peak, which has the effect of delaying the date of peak.
452. Peak Oil Awareness.One of the declared missions of ASPO has been to raise awareness of Peak Oil: in fact it more or less coined the term. In this, it has definitely succeeded as references to Peak Oil now explode throughout the world with new websites appearing almost by the hour to address the issue. It also naturally triggers increasingly vicious responses from the flat-earth community who are forced onto the defensive. The following is an example of such material:
453. A Change of Direction by British GasIn earlier years, Britain’s gas supply was managed by a State entity with long-term national responsibilities, but then the famous Mrs Thatcher privatised it so that investors, speculators and managers could pocket the profits, often in excessive terms, under free market, kleptocratic principles. Now, the Company, which clearly sees the Country’s gas supply falling steeply from depletion, has introduced a new policy. After failing to convince a blind central government, it has succeeded in persuading two urban local authorities to grant tax rebates to householders who cut the waste of energy by installing insulation and efficient light bulbs. It is estimated that as much as £5 billion worth of energy is wasted in UK households. Most remarkable of all is the abandonment of flat-earth economic principles whereby the company discourages the consumption of its product in the national interest. There is hope yet.
454. A Sense of ProportionThe well-known Lake of Geneva in Switzerland is about is 100 km long, 10 km wide and 300 m deep. That gives 300 billion cubic meters or 1887 billion barrels (at 2.69 b/m3). This is approximately the same volume as the World’s total endowment of producible Regular Oil. The oil lake is now about half empty. ( Contributed by Jack Zagar ) 455. BP admits to PeakOf all the oil companies, BP has been the least forthright in explaining the Peak Oil issue, using the concept of Reserve to Production Ratio to give the misleading impression that Reserves support present production for 40 years, as if it were remotely plausible that production would drop to zero the year after. It is therefore very encouraging to find one of its executives, Francis Harper, not only admits to Peak but supports an ultimate recovery for all liquids of 2400 Gb, confirming the ASPO estimate (see Table p.2). BP is evidently now following the lead of ExxonMobil in coming to terms with this subject. The Chairman of Total has also included the ASPO forecast in his presentation. (See www.thebusinessonline.com) (Reference furnished by Jean Laherrère) 456. Remarkable BBC ProgrammeA remarkable programme was scheduled to be broadcast on BBC2 on November 18th entitled The Man Who Broke Britain. It covers the story of a fast-moving new bank working the Derivatives Market in which the trader had placed an oil price escape clause. An explosion in Saudi Arabia results in a price shock, causing a market melt-down throughout the world. At first, it is attributed to al-Qaeda financial terrorism, but is eventually found to be just normal banking. The financial collapse leads to widespread unemployment and demonstrations in the streets as the new destitute react. Government officials and politicians offer bland assurances that the underlying economy was strong, taking a long time to come to terms with the situation. Since the story is so close to reality due to the, now acknowledged, near absence of the spare capacity, the programme runs a good chance of being self-fulfilling, which might explain why the BBC at the last moment decided not to show it, although we hear now that it may be broadcast on December 9th on BBC2 at 21:00. Don’t miss it, if it appears. ( Reference furnished by Alison Kenter of WalltoWall TV ) 457. External Costs of PetroleumThe International Center for Technical Assessment has published a comprehensive study of the external cost of using petroleum, including road building, pollution, administration, environmental, and military costs, and finds that the real cost of gasoline in the United States is between $5 and $15 a gallon. Declining production in the future will naturally reduce these external costs, but the alternatives may also carry their own, possibly even higher ones.

459. Correction to ModelThe Depletion Model evolves all the time based on new data and insight. The Table on Page 2 has been revised to reflect a more reasonable assumption of heavy oil production based on the evaluation of Canada in Item 449. The resulting Ultimate for All Liquids falls to 2400 Gb after rounding, identical to that proposed by BP (see Item 455), and is only slightly below the USGS High Probability Case of 2452 Gb. As computed, the resulting midpoint peak of Regular Oil comes in 2005, and of All Liquids in 2007, but they are shallow peaks. A full revision awaits publication of this year’s data in December. 460. No Change for Climate ChangeThe Intergovernmental Panel on Climate Change has decided that the Fourth Assessment Report, which is to be issued in 2007 will keep the same flawed scenarios (SRES) as given in the 2001 Third Assessment, which it judges to be reliable despite widespread criticism. In general, it seems that the organisation will not face criticism directly but retreat behind academic peer group evaluations. The trouble is that the peer group is likely to be the self-same academic economists, lacking the knowledge or mindset to address the resource limitations imposed by Nature. Climate Change is certainly an important subject deserving the closest scrutiny, so it is unfortunate that those responsible continue to provide misleading information to governments when their case would be strengthened not weakened by properly addressing the energy depletion issue and its impact on the economy and population at large, as has explained, for example, by Laherrere in several papers including:
461. London Conference on DepletionThe Institute of Energy hosted an important conference on depletion in London on November 10th. Chris Skrebowski, Editor of Petroleum Review, set the scene by urging the participants to face the facts and look at the numbers, confused as some of them undoubtedly are. Dr Bentley followed with an excellent comprehensive review, in turn supported by Francis Harper of BP and Ken Chew of IHS presenting realistic assessments of discovery and corresponding production profiles. They were countered by the well known flat-earth assertions of Professor Odell, who yet again tried to invoke an abiotic origin of oil to support his notion of a limitless resource. He was partly supported by Robert Arnott, from an Oxford flat-earth tank, who suggested that the lack capacity reflected a lack of investment, restrictions to exploration in certain countries and the senility of explorers, whose average age is apparently 49. But he did confess to being in ignorance of the facts because the data cost too much for him to buy. Finally Michael Smith pointed out that if, for the sake of argument, the claims of potential increased capacity by the Middle East countries were accepted at face value, dubious as they were, there would still be a shortfall to world supply by 2011, assuming a 1.5% annual increase in demand. 462. Britain’s Energy Time BombThe following article reveals a new position by the British Government, which is now forced to admit to Peak Oil. The most telling line refers to a foreign policy of “Country Action Plans on Energy”. The price can be high with more than 100 000 innocents killed in Iraq so far.
Calendar - Forthcoming Conferences and MeetingsThe subject of Peak Oil will be addressed at the following conferences and meetings, with presentations being made by ASPO members and associates [shown in parenthesis]: 2004 2005 [Information on future events for inclusion in the Calendar is welcomed]

Even the U.S. government agrees that the amount of oil that can be pulled from the planet is finite. But it estimates that global oil production will likely peak in 2037, rather than in 2008. "All or nearly all of the largest oil fields have already been discovered and are being produced. Production is indeed clearly past its peak in some of the most prolific basins," the federal Energy Information Administration (EIA) said in a recent report on peak oil.
Supply and production scares in places like Russia and Nigeria have boosted prices recently more than worries about the end of the oil age. "Countries are always drilling and exploring for oil (despite political turmoil), because there is power in having oil," ASPO's Aleklett said in a recent interview. "This takes us to the heart of a security issue," added Rodgers. "It is likely that OPEC can step in and meet demand if a peak in non-OPEC regions happens. But then we'll be even more dependent on parts of the world that aren't stable and reliable."
