| The End of Cheap Oil, by Colin J. Campbell, Jean Laherrere |
| Issues in S and T, Spring 2005, Peaking Oil Production: Sooner Rather Than Later?i 1st, extensive drilling for oil & gas has provided a massive worldwide database, & current geological knowledge is more? extensive than in years past.i Nevertheless, the oil reserves discovered per exploratory well have been declining worldwide for more than a decade.i i This multitude of wells also helps to estimate the size of the discovery’s “reserves”: the total amount of recoverable oil in a reservoir. i Reserves are an estimate of the amount of oil in a reservoir that can be extracted at an assumed cost.i In well-managed oil fields, although estimates of reserves will rise with increases in price, the maximum increase is usually only 10 to 20 % no matter how high the price. i Reserves estimates are but one factor in estimating future oil production from a given reservoir.i A large oil field can have large estimated reserves, but if the field is past its maximum production, the remaining reserves will be produced at a declining rate.i When world oil production peaks, there will still be large reserves remaining.i In the past, higher prices led to increased estimates of conventional oil reserves worldwide.i |

| The End of Cheap Oili Dividing that figure by the current production rate of about 23.6 Gbo a year might suggest that crude oil could remain plentiful & cheap for 43 more years - probably longer, as official charts show reserves growing. i Using several different techniques to estimate the current reserves of conventional oil & the amount still left to be discovered, we conclude that the decline will begin before 2010. i The 2nd is an estimate of reserves, the amount that companies can pump out of known oil fields before having to abandon them.i EG?, if, as geologists estimate, there is a 90 % chance that the Oseberg field in Norway contains 700 million barrels of recoverable oil but only a 10 % chance that it will yield 2,500 million more barrels, then the lower figure should be cited as the so-called P90 estimate (P90 for "probability 90 %") & the higher as the P10 reserves. According to our calculations, the world had at the end of 1996 approx 850 Gbo of conventional oil in P50 reserves,substantially less than the 1,019 Gbo reported in the Oil & Gas Journal & the 1,160 Gbo estimated by World Oil. The difference is actually greater than it appears as our value represents the amount most likely to come out of known oil fields, whereas the larger number is supposedly a cautious estimate of proved reserves. i GROWTH IN OIL RESERVES since 1980 is an illusion caused by belated corrections to oil-field estimates.i A more important cause of the expansion lies in revisions: oil companies replaced earlier estimates of the reserves left in many fields with higher numbers.i John D. Edwards of the University of Colorado published last Aug one of the most optimistic recent estimates of oil remaining: 2,036 Gbo.i |

| Earth Day '96: Are We Running Out of Oil?iProved oil reservesi But the volume of oil remaining in the ground is unobservable--& therefore highly speculative. Consequently, estimates of the amount of oil remaining in the earth's crust are uncertain. Current estimates of proved reserves in the U.S. stand at approx 23 billion barrels. Globally, proved oil reserves stand at nearly a trillion barrels, enough to sustain 1993 production for another 45 years.i Perhaps even more surprisingly, oil reserves at the end of that period stood at 23 billion barrels--3 billion barrels more than total reserves in 1945! i The definition of "proved reserves" was set in 1925, when the American Petroleum Institute (API) defined domestic reserves as the volume of crude oil that geological & engineering information indicate, beyond reasonable doubt, to be recoverable in the future from an oil reservoir under existing economic & operating conditions.i Explicitly excluded was any estimate of future reserve additions at known fields that are probable but not yet proved, as well as future reserves from undiscovered fields, on grounds that "an estimate of reserves which are to come from fields yet to be discovered involves so many uncertainties that it would be grossly inaccurate & misleading." i These unconventional oil resources are about 3 times as large as the volume of original conventional oil in place, & about 10 times the volume of remaining recoverable conventional oil worldwide. i |

| The Great Rollover Juggernaut - World Oil Depletion and the Inevitable Crisisi Recent Signs of Trouble Matt Simmons CSIS 2/24/04 presentation: "Proven reserve write-off is likely worldwide" Aramco's 2/24/04 definition of Saudi Arabia's "Proved Reserves" - just include all past production.i its ?an early admission that what is left of the world's oil reserves is shrinking.i Would you like to guess how many executives of other major oil companies will be eager tell the truth about their reserves?i 1st, published tables of world oil reserves are based on what individual countries claim as "proved reserves".i In the late 1980's all the Middle East countries inflated their "proved reserves" to maintain their share of OPEC production after Venezuela added "heavy oil" to its reserves.i An article in the June 17, 2002 issue of the Oil & Gas Journal pointed out these "claimed" estimates should be lowered by 180 billion barrels.i A technical article posted at: http://www.searchanddiscovery.net/documents/gong03/index.htm indicates that remaining expected recovery (...) in Iraq's 28 largest oilfields is only 41 billion barrels.i A mathematical calculation using this data indicates the world's remaining reserves in these giant fields (...) is less than one trillion barrels of oil equivalent.i |

| "http: //www. prospect. org/ print- friendly/ print/ V12/ 18/ deffeyes- k. html"i During each ensuing decade, more oil reserves would be added & the industry actually would grow instead of drying up.i Around 1995 several analysts began applying Hubbert's method to worldwide oil production. Most of them estimate that the peak year for world oil will be between 2004 & 2008.i The production curve, he found, lags consistently behind the bell curve of cumulative oil discoveries (...). But reliable estimates of oil reserves are a vital ingredient in a Hubbert analysis, & this leads to the chief difficulty in using the method to predict the peak of world oil production: In the late 1980s, several OPEC nations reported huge, abrupt increases in their oil reserves. OPEC had recently changed its rules, assigning each member nation a share of the oil market based not just on the country's annual production capacity but also on its oil reserves.i Oil reserves are defined as future production, using existing technology, from wells that have already been drilled. It's a lot more fun to go into the boss's office next year & announce that there is actually a little more oil than last year's estimate predicted.i |
