What Is Peak Oil?reaches itsThe date an area‟s oil productionmaximumMeans that about half the oil has been produced Does not mean “running out of oil” Does mean a continuous decline in productionWhen oil half gone, the flow of oil begins to fall Not like a gas tank Oil in the ground is not in a pool but in tiny droplets Droplets move slowly through the earth due to pressure At halfway point pressure drops – flow decreases

Lots of bad news, but It‟s not hopeless!! Human ingenuity and technology are remarkable. Appropriate policy choices are available to minimize and adapt to climate change.Maybe we‟ll be lucky, and unanticipated factors or feedbacks may slow therate of change. Perhaps we (esp. U.S.) will be forced to change by the price and availability of fossil fuels. 13

Oil wealth has made possible rapid economic development,which began in the 1960‟s and accelerated in the 1970‟s.Saudi oil reserves are the largest in the world, and Saudi Arabia isthe world‟s leading oil producer and exporter.A major new gas initiative promises to bring significantinvestment by the US and European oil companies to developnon-associated gas fields in three separate parts of Saudi Arabia.In April 2000, the government established the Saudi ArabianGeneral Investment Authority to encourage foreign directinvestment in Saudi Arabia.
The population of Saudi Arabia is approximately 22,757,092, which includes 5,360,526 non-nationals. 42.52% of the population is aged 0-14. 54.8% of the population is aged 15-64. 2.68% of the population is 65 years old or older.

Saudi Arabias crude oil production peaked in 2005 at 9.6 mbd. In 2010 Saudi production averaged 8.2 mbd. According to official Saudi sources, Saudi oil production will not increase beyond 8.7 mbd until 2015. And as domestic consumption is projected to grow by 5% per annum, Saudi exports are expected to shrink by 10% in the next 4-5 years (see Table 2). A steady production decline was forecast from 2010 onwards (see Figure 1).

Most Middle East producers have passed their prime. Iran peaked at 6 million barrels/day in 1970s. Iraq, Kuwait, Oman, Syria and Yemen have all passed peak output. UAE and Iraq might have growth prospects. Many giant Middle East oilfields are far past Peak Oil. Saudi Arabia has 36% of Middle East reserves.

“Oil has never run out.” Great new discoveries “must be around the corner”. Proven oil reserves (1.2 trillion barrels) equates to 40 years current use. Oil sands and other unconventional oil wait in the wings. High oil prices will likely create new energy supplies, economists are our „high priests‟.
THE DEBATE OVER RESERVES: PESSIMISTS AND OPTIMISTSDuring the 1990‟s, the debate over oil reserves generatedcontroversy between the "pessimists" and the "optimists". Oil is so important that publishing reserve data has become a political act. Most of the dispute between the so- called pessimists (mainly retired geologists) and the optimists (mainly economists) is due to their using different sources of information and different definitions. The pessimists use technical (confidential) data, whereas the optimists use the political (published) data. “
PESSIMISTS •the world is finite and so are its recoverable oil resources • all of the oil-bearing regions worth exploring have already been explored • the big fields have already been discovered • claim that official figures for proven reserves have been overestimated • world oil production is currently at its optimum (peak) and will decrease steadily •Geologists and physicists tend to hold this position. OPTIMISTS •hold a “dynamic” concept of reserves • believe that volumes of exploitable oil and gas are closely correlated to technological advances, technical costs and price • tend to be economists
Ghawar has produced about 60% of all Saudi Arabian oil from 1951-2004 and still accounts for some 50% of the Saudi production When Ghawar output declines, Saudi production will most likely have peaked After peak in Saudi Arabia it is difficult to envisage a global increase in conventional oil production
The entire world assumes Saudi Arabia can carry everyone‟s energy needs on its back cheaply. If this turns out to not work, there is no “Plan B”. Global spare oil capacity is now “all Saudi Arabia”. No third-party inspector has examined the world‟s most important insurance policy for years. Conventional wisdom says “Do not worry, Saudi Arabia has always come up with the goods.” If conventional wisdom is wrong, the world faces a giant energy crisis.
Saudi Arabia problemsSince 1970, Saudi Arabia has been the world‟s “swingproducer” of petroleum: the only country capable ofgreatly increasing production in a short time (in responseto supply interruptions such as hurricanes in GOM,violence in Nigeria, war in Iraq).KSA insists it still can fulfill the role of swing producer,but releases no verifiable data....its attitude is “trust us.”Analysts are (finally) starting to get very concerned (MattSimmons). A. Unexplained jump in reserves in 1990 (170 to 258 Gb). B. Ghawar reserves? 70 Gb (SA); 25–40 Gb (analysts).71
C. Almost all KSA production comes from 6 supergiantfields, and >60% comes from Ghawar. All six werediscovered 40–60 years ago. Five of the six have producedat very high rates for most of their history.D. At least some of the wells in these super giant fieldsare producing very, very high amounts of water withpetroleum(70% to 90%; 30% is typical trouble level). Inother fields, these levels have led to very rapidproduction declines.E. Saudi Aramco says production from existing fieldsdeclines 8% every year. Thus, KSA needs to increaseproduction by up about 1 million barrels/day every yearjust to compensate.72
The Ghawar field found in 1948 has produced 60% + of Saudi oil, is now producing approx. 5 million bopd and is approaching its tail. When Ghawar peaks, Saudi will have peaked and so will the world. Indications are that the OPEC “swing production is about to be exhausted
Peak means that production can no longer be increased; we have then produced about half of the oil After peak the price of oil will be market driven
Multinational companies depend on cheap energy for global trade. The whole economic model of more and more each year will have to be re thought. Everything possible will be brought into service to maintain the current economic system. Unpredictable consequences.
► Last man standing► Wait for the techno fix► Powerdown► Create lifeboats
Action required on two fronts (Think globally; act locally):Personal lifestyle changesAchievement of world wide political consensus and action. - Shift of consciousness?
► Adopt the Uppsala protocol - Distribution of remaining energy, rather than fight over it.► Reduce population and consumption to long term carrying capacity by each country living within its ecological footprint►Oppose the scandalous promotion of Nuclear power►Press for meaningful debate about our energy future.
► Let as many people as possible know about peak oil www.Livingonthecusp.org www.peakoil.net► Get informed Web based news The Ecologist, Resurgence, Positive news
► Chose a low energy lifestyle.► Learn to live and really live with less not just make do. "Faced with a choice between the survival of the planet and a new set of matching tableware, most people would choose the tableware" - George Monbiot
► Create communities. You can‟t go it alone.► Re-localise economies and energy production.
If we use this opportunity to radically change what we do and how we do it, (adopt a post industrial society), then something positive can emerge. However, if treat this as just an energy crisis then we are setting ourselves up for a bigger fall further down the line.
