I can't understand why 1960/1970 known reserve then are still being presented.
Most claim there is only 20 billion or 30 billion known reserves, but it is many times more than that. Also, wells that went dry in the 1970's, are producing again at capacity and will produce as long as they did 40 years ago. There is something going on that we do not know yet - oil may not be fossil fuel, it may be made in the mantle and a renewable energy, i.e unlimited supply.
There is also more than 500 years of coal, more than 300 years of natural gas, and more than 1000 years of methane hydrate.
There have been dozens of predictions for when we would run out of oil since oil was discovered, and the predictions were exceeded every time.
Timeline -
One of many sources - (http://www.radford.edu/~wkovarik/oil/5oilreservehistory.html)
• 1857 -- Romania produces 2,000 barrels of oil, marking the beginning of the modern oil industry.
• 1859, Aug. 25 -- Edwin L. Drake strikes oil in Titusville, Pennsylvania
• 1862 -- First commercial oil production in Canada, also 1863 in Russia.
• 1862 -- Most widely used lamp fuel (camphene) taxed in US at aprox. $1 a gallon; kerosene taxed at 10 cent per gallon. (Kovarik, 1997)
• 1863 -- John D. Rockefeller starts the Excelsior Refinery in Cleveland, Ohio.
• 1879 -- US Geological Survey formed in part because of fear of oil shortages.
• 1882 -- Institute of Mining Engineers estimates 95 million barrels of oil remain. With 25 milliion barrels per year output, "Some day the cheque will come back indorsed no funds, and we are approaching that day very fast," Samuel Wrigley says. (Pratt, p. 124).
• 1901 -- Spindletop gusher in Texas floods US oil market.
• 1906 -- Fears of an oil shortage are confirmed by the U.S. Geological Survey (USGS). Representatives of the Detroit Board of Commerce attended hearings in Washington and told a Senate hearing that car manufacturers worried "not so much [about] cost as ... supply."
• 1919, Scientific American notes that the auto industry could no longer ignore the fact that only 20 years worth of U.S. oil was left.
• 1920 -- David White, chief geologist of USGS, estimates total oil remaining in the US at 6.7 billion barrels.
• 1925 -- US Commerce Dept. says that while U.S. oil production doubled between 1914 and 1921, it did not kept pace with fuel demand as the number of cars increased.
• 1928 -- US analyst Ludwell Denny in his book "We Fight for Oil" noted the domestic oil shortage and says international diplomacy had failed to secure any reliable foreign sources of oil for the United States. Fear of oil shortages would become the most important factor in international relations, even so great as to force the U.S. into war with Great Britain to secure access to oil in the Persian Gulf region, Denny said.
• 1926 -- Federal Oil Conservation Board estimates 4.5 billion barrels remain.
• 1930 -- Some 25 million American cars are on the road, up from 3 million in 1918.
• 1932 -- Federal Oil Conservation Board estimates 10 billion barrels of oil remain.
• 1944 -- Petroleum Administrator for War estimates 20 billion barrelsof oil remain.
• 1950 -- American Petroleum Institute says world oil reserves are at 100 billion barrels. (See Jean Laherre, Forecast of oil and gas supply)
• 1956 -- M.King Hubbard predicts peak in US oil production by 1970.
• 1966 - 1977 -- 19 billion barrels added to US reserves, most of which was from fields discovered before 1966. (As M.A. Adelman notes: "These fields were no gift of nature. They were a growth of knowledge, paid for by heavy investment.")
• 1973 -- Oil price spike; supply restrictions due to Midde Eastern politics.
• 1978 -- Petroleos de Venezuela announces estimated unconventional oil reserve figure for Orinoco heavy oil belt at between three and four trillion barrels. (More recent public estimates are in the one trillion range).
• 1979 -- Oil price spike; supply restrictions due to Midde Eastern politics.
• 1980 -- Remaining proven oil reserves put at 648 billion barrels
• 1993 -- Remaining proven oil reserves put at 999 billion barrels
• 2000 -- Remaining proven oil reserves put at 1016 billion barrels.
• 2005 -- Oil price spike; supply restrictions and heavy new demand
• 2008 -- Oil price spike; supply restrictions and heavy new demand, global economies collapse when oil reaches over $140 USD/bbl.
Notice that as time goes on, the reserves keep rising exponentially? The reserves they are publishing global reserves and it will be in about 300 to 500 years from now as it stands today. Who knows, next century they could be warning we only have 1000 years of oil left.
No need to worry for more than 15 to 25 generations. I think they will be smart enough to know what to do without our help.
