How long does the oil reserves in the world lasts?

There's four times more discovered oil in the ground not being used than this is in currently being drilled.\n\nThere's enough oil in the United States that if it were all drilled we wouldn't need to import any oil from anyone.\n\nNext time you see some assclown liberal be sure to thank them for the $3 per gallon gas.

It is a non-renewable fossil fuel.  Oil and natural gas are also fossil fuels.

Yes, actually it will. well, not really run out of oil but obtainable oil.  It is estimated that drillable oil reserves could be extinguished within 50 years given present usage and the estimation of future usage.

~I assume somewhere in this drivel you actually think you posted a question.  Sorry I was to ignorant to figure out what it was.  Maybe you should consider going back to school to learn how to speak and write in intelligible English.  As to to concept of oil being a renewable resource, of course it is.  It just might take a few million years for the ferns to grow, decompose and transmogrify.  What the hey, Sequoias are renewable too.

While the supply of oil is likely to go into a decline within a  decade (some scientists think it already has) there will be many things that will help to extend the supply, so it is unlikely to completely run out for many decades. Some well informed predictions suggest that by 2050 the world will be essentially running on empty, but many things could change over the next 40 years. \nhttp://www.energybulletin.net/primer.php\n\nIt is true that most of the major oil companies have been failing to discover as much new oil each year as they are producing, leaving us currently with falling oil reserves, but the real problem at present is that consumption is growing and has reached a record 83 million barrels of oil per day worldwide. Oil demand is one of the reasons that it is so hard to predict how long our oil supplies will last. When oil reached record high prices in the early 1980's the demand for oil dropped off dramatically. So far, there has been little reduction in demand as a result of the currently high prices in the market. If oil demand drops significantly world oil reserves could last much much longer. \n\nSeveral factors will change the supply of oil as prices increase. Right now many smaller companies are drilling for small oil reserves profitably and successfully. The major oil companies are still ignoring these small reserves as they have difficulty making a return on investment, while the small companies can easily find, produce and profit from 1 million barrel reservoirs. These types of oil reservoirs exist all over the world within the areas where major oil discoveries have been made, but have generally been ignored because these small reservoirs will only produce for a few years and often take more work  to find relative to the size of the discovery than the large fields.  However, many existing oil fields that have been considered depleted are proving to still have a second life in them in the form of these small reserves left behind and missed the first time. These types of reserves are likely to become a major factor in slowing the decline in future years and the oil exploration business may become dominated by small companies that are more agile and creative than the large majors.  \n\nThe other thing to consider is that recovery of oil from a typical oil reservoir is often only about 50% of the oil. If you think about this, it means that it is likely that for the trillion barrels of oil that the world has recovered and consumed, another trillion barrels was left behind. If, and this is a big if that is very much unknown, a new technology is invented that will make it possible to recover this previously 'unrecoverable' oil, the world's oil supply might be extended for many more years. Some techniques already exist to do secondary recovery and these are likely to utilized much more as oil prices rise.  \n\nAs oil prices rise there is much more incentive to use alternative fuels and energy sources like ethanol, methanol, biodiesel, hydrogen, nuclear, coal, tar sands, oil shale, solar, wind, geothermal, hydroelectric, tidal power, biomass, methane hydrates, etc. Each of these types of energy may start taking up some of the current market for oil and as they begin making larger and larger contributions to the energy mix, there will be less demand for oil, stretching out the decline curve even further.\n\nIf you want to keep up with changes and events related to energy production and peak oil I suggest the following web page:\nhttp://www.energybulletin.net/news.php?cat=64  \n\nThe one thing you can be sure of, if the current demand for oil does not decline, the price of oil in the future is very unlikely to be cheaper because it is very unlikely that we can drill our way out of this supply problem.

Specifically as crude oil the best estimate is 2.2 trillion barrels. That includes estimates of undiscovered oil. Known remaining reserves of crude oil are about 890 billion barrels.\n\nHowever, to truly consider remaining reserves you must consider natural gas and NGL's (natural gas liquids). The most reliable estimate is that about 4.9 (Four and nine-tenths: sorry Yahoo seems to be censoring nines)trillion barrels of oil equivalent remain. The "equivalent' part is because natural gas and condensate are also included in that estimate, while these are normally measured in cubic feet and not barrels. This estimate does not include tar sands, oil shale, or gas hydrates which may all make significant contributions in the future. Tar sands are already producing significant oil in northern Canada.   \n\nThe estimate includes remaining reserves, reserve growth (a phenomenon where initial estimates of oil in place often are found to be too low after the fields are fully explored), and estimates of undiscovered oil. Undiscovered oil can be estimated by examining what are called petroleum systems, where basins have formed significant deposits that should contain oil. \n\nThis estimate was made by the USGS in 2000 and the results are published in an American Association of Petroleum Geologists book titled "Global Resource Estimates from Total Petroleum Systems".

Ok, maybe I would be a better person to ask this question since I actually work in the industry finding the stuff. Seems to me some people have made up they're own minds without much knowledge of the industry.\n\nAs one guy has pointed out, yes as it takes millions of years to from and the amount we have used thus far is greater than that being made naturally. \n\nHowever, what people fail to realise is that its the larger discoveries which for the past decade has been in decine due to the price of oil. As such, oil companies were reluctant to spend money in exploration because of the decreased profit they would make. Since Bush decided to invade Iraq, the oil price shot up and now exploration is booming. More discoveries are being made, and production is up.\n\nAlso as you have mentioned there are places which have yet to be discovered. I recently was working for a company which did an exploration well which they had been planning for 20 years! Long time planning if you ask me, but the reason it took so long was because the techonolgy avaliable was not around at the time to explore it. We can only explore within the capabilities of current techonolgy. Not only that there are vast areas of the world that have yet to even be siesmically survey'ed, for example the Pacific Ocean, big huge expanse of water, how long do you think it would take to map the sub surface geology?\n\nAs for your third part of your question, there is such a thing as extended reach drilling, where (as the name suggests) they drill long sections and could quite easily tap potential reservoirs without damaging sensitive environments. Such drilling goes on in the UK.\n\nAll in all no the oil is not running out, these next few years are going to see and peak in the production of oil since hte industry started.\n\nP.S. Removing the oil from the ground doesnt in any way shape or form cause volcanoes as the guy above me suggested, that is mearly ill' education!

Because we still have plenty of coal, oil, and nuclear power supplies and will continue to use these until the world's entire infrastructure changes.  Oil will surely continue to used until every last drop is gone, and the world is forced to use something else.

In truth, most every major land mass has natural gas reserves, but has motivation to not use them. China, for example, just entered into a 3-year, multi billion (or maybe trillion, I forgot) dollar deal with Iran for Oil. China probably has oil, but given it's mountainous terrain, probably not worth it. \n And there is political motivation. As we move forward in the steps in a war with Iran, China effectively halted a great amount of advance by siding with Iran, espicially considering our rather large debt to the Bank of China. And as the Middle East is known as a "conflict zone", and being in the Middle East as I write this, I can agree, the long-term idea for many nations, esp. those in the U.N., is forcew the OPEC nations to sell away their prime export, leaving them succeptable to influence in later years.\n   America has a great deal of oil. Much more than Iraq in Texas alone. But we chose to leave wells covered, so as to ensure that the US will be able to function in the decades to come.\n   As far as dinosaurs.... couldn't say, but if you were to observe the geographic locations where there are several skeletons/fossils found, these lands are not known for being rich in oil\nhope that helps some.

antartica reputedly has a massive amounts of oil reserves but due to environmental protection cannot be checked.\n\nsiberia has huge amounts also but russia being so poor cannot do much with it in large quantities.\n\nrecently the north sea and gulf of mexico again have found new fields as well as the caspian sea.

Oil officials 10, 20, 30, and 40 years ago said AT THAT TIME that we were going to use up what was known to be total global "proven oil reserves." We keep finding more total oil reserves every few years than was thought to exist worldwide a few years previous - kind of funny logic, isn't it? If we keep finding more oil that exceeded known reserves just a few years back, then what are we so concerned about? Interestingly enough, at the same time we keep finding more proven oil reserves, people keep screaming more and more that we are running out of oil - who is right? History says we can keep finding oil, so maybe there is a regenerative process unknown to the scientific community - they can't possibly know everything about everything. \n\nOnly one thing is certain in SCIENCE: it IS ALWAYS CHANGING. Geologists have been getting better year after year at locating oil reserves, and yet so little is known about oil reserves other than location. What is understood to be fact now will be ridiculed in the future by new theories - which have already happened. They thought we couldn't use most crude oil in the early 20th century because nobody knew about cracking or synthesis of crude products, so they just dumped unusable crude products that were not immediately usable as gasoline or diesel. We have come very far since that time in chemistry alone. \n\nIsn't it interesting that what is vaguely understood by a few scientists is continuously spouted as "truth" by those who know far less. SCIENTIFIC FACT IS CHANGEABLE, meaning it can be tested, and if a different result occurs, then the theory changes, resetting what is known as "fact." Oil may be replenishable, and may not necessarily only come from prehistoric plants and animals as current thought suggests. You raise an interesting argument about oil resources, and only the future will let us know for sure - but there will be a definitive answer. Now, who is ready for the truth?

"If you keep it clean, cool and dry, diesel fuel can be stored 6 months to 1 year without significant quality degradation. Storage for longer periods can be accomplished through use of periodic filtrations and addition of fuel stabilizers and biocides."

We all know all good things come to an end, just like the Roman empire came to an end after 600 hundred years, i believe the U.S. will last no more than 2,000 years. I hope I will be proven wrong but that is my best guess.

Yes.  But unfortunately even if all the oil in Alaska was recoverable, it still wouldn't have a noticeable effect on gas prices.  The US uses 19 million barrels of oil a day.  The US Geological Survey estimates there are 10.4 billion barrels of recoverable oil in ANWR.  That's only enough to supply the US's demand for 1.5 years.  And then, as its a non-renewable resource, that oil is gone forever.

oil is not a sustainable resource, so it will not last forever. \n\nSustainable resources, like sustainable agriculture, and sustainable development is  a way that we can configure human development a society in such a way that it does not compromise the need of future inhabitants of earth, this includes not just your children, by your childrens children and so on. I have included a link on sustainability it is packed with information and tons of resources to learn more about why it's essential to our existence. People are getting together everyday in this country (and with other countries) and around the world to create and improve sustainability.

There is plenty of oil for years to come.\n\nBut is your question about Canada predicated on the bizarre theory that we invaded Iraq for oil? That is so laughable that you need severe ridicule and degradation for being so gullible or delusional. I'm too tired right now.

Try Reading the END OF OIL by Paul Roberts.\nIt'll run out a darn-sight sooner than we thought!\nOIL companies have/did lie about the amount of oil they have left.\nThe oil that is being pumped now has 2 go thru more refining than ever B4 & is down 2 the amount of Sea water they pump in 2 the fields.\nEverytime a alternative 2 oil is investigated the Oil companies surpress the data.  They R not going 2 give up on oil until every last drop has been extracted & no-one can predict exactly what affect this will have on the Planet. I'm sure that any warnings would proberly supressed by the oil companies 2.
