At a lecture on ‘Geohazards’ earlier this month as part of the postgraduate Natural Hazards for Insurers course at University College London (UCL), Dr. Richard G. Miller, who worked for BP from 1985 before retiring in 2008, said that official data from the International Energy Agency (IEA), US Energy Information Administration (EIA), International Monetary Fund (IMF), among other sources, showed that conventional oil had most likely peaked around 2008.
"We need new production equal to a new Saudi Arabia every 3 to 4 years to maintain and grow supply… New discoveries have not matched consumption since 1986. We are drawing down on our reserves, even though reserves are apparently climbing every year. Reserves are growing due to better technology in old fields, raising the amount we can recover – but production is still falling at 4.1% p.a. [per annum]."
"… a sustained decline in global conventional production appears probable before 2030 and there is significant risk of this beginning before 2020… on current evidence the inclusion of tight oil [shale oil] resources appears unlikely to significantly affect this conclusion, partly because the resource base appears relatively modest."
"Greater reliance upon tight oil resources produced using hydraulic fracturing will exacerbate any rising trend in global average decline rates, since these wells have no plateau and decline extremely fast – for example, by 90% or more in the first 5 years."
"Crude oil production grew at approximately 1.5% per year between 1995 and 2005, but then plateaued with more recent increases in liquids supply largely deriving from NGLs, oil sands and tight oil. These trends are expected to continue… Crude oil production is heavily concentrated in a small number of countries and a small number of giant fields, with approximately 100 fields producing one half of global supply, 25 producing one quarter and a single field (Ghawar in Saudi Arabia) producing approximately 7%. Most of these giant fields are relatively old, many are well past their peak of production, most of the rest seem likely to enter decline within the next decade or so and few new giant fields are expected to be found."
"The oil price has risen almost continuously since 2004 to date, starting at $30. There was a great spike to $150 and then a collapse in 2008/2009, but it has since climbed to $110 and held there. The price rise brought a lot of new exploration and development, but these new fields have not actually increased production by very much, due to the decline of older fields. This is compatible with the idea that we are pretty much at peak today. This recession is what peak feels like."
"We’re like a cage of lab rats that have eaten all the cornflakes and discovered that you can eat the cardboard packets too. Yes, we can, but… Tight oil may reach 5 or even 6 million b/d in the US, which will hugely help the US economy, along with shale gas. Shale resources, though, are inappropriate for more densely populated countries like the UK, because the industrialisation of the countryside affects far more people (with far less access to alternative natural space), and the economic benefits are spread more thinly across more people. Tight oil production in the US is likely to peak before 2020. There absolutely will not be enough tight oil production to replace the US’ current 9 million b/d of imports."
"We are probably in peak oil today, or at least in the foot-hills. Production could rise a little for a few years yet, but not sufficiently to bring the price down; alternatively, continuous recession in much of the world may keep demand essentially flat for years at the $110/bbl price we have today. But we can’t grow the supply at average past rates of about 1.5% per year at today’s prices."
"In the US, high oil prices correlate with recessions, although not all recessions correlate with high oil prices. It does not prove causation, but it is highly likely that when the US pays more than 4% of its GDP for oil, or more than 10% of GDP for primary energy, the economy declines as money is sucked into buying fuel instead of other goods and services… A shortage of oil will affect everything in the economy. I expect more famine, more drought, more resource wars and a steady inflation in the energy cost of all commodities."
"… the minimum oil price needed to increase the oil supply in the near term is at levels consistent with levels that have induced past economic recessions. From these points, I conclude that, as the EROI of the average barrel of oil declines, long-term economic growth will become harder to achieve and come at an increasingly higher financial, energetic and environmental cost."
