The International Energy Agency (IEA) has provided an unrealistically high oil forecasts in its new 2012 World Energy Outlook (WEO) according to Gail Tverberg and reported in the Oil Voice Magazine of December 2012.
The IEA claims that the US will become the world’s largest oil producer by 2020 and will become a net oil exporter by 2030.
One reason that the WEO 2012 estimates are unreasonable is because the oil prices shown are comparatively low relative to the production amounts forecast in the report. This is mainly because easy –to –produce oil becomes depleted and when more difficult reservoirs are tapped, the cost of extraction will increase.
The economically extractable oil referred to as “tight oil” is already reaching its production limits, at current prices. The only way these production limits are to be overcome is with high oil prices much higher than the IEA forecasts.
High oil prices cause a serious problem because of their impact on the world economy. IEA has stated that the current high oil prices are already affected the global economy .Accordingly higher oil prices also mean that investment costs required to reach target production levels will be even higher than forecast by IEA which is another impediment in reaching its forecast production levels.
If higher prices put the economies of oil importing nations into recession, then oil prices will drop lower, reducing the incentive to invest in new oil production infrastructure. Accordingly we will find ourselves at the peak of oil extraction termed “peak oil” because of an economic dilemma: while there seems to be plenty of oil available, the cost of extracting it may be reaching a point where it is more expensive than consumers can afford. As a consequence, some oil that we have discovered and counted as reserves, will have to be left in the ground.
The IMF has recently done modeling that is relevant to this issue in a working paper called “Oil and the World Economy Some possible Futures” This analysis may provide some insight to the real situation.
Problem of diminishing returns
It has been revealed that the IEA has not properly modeled the issue of declining resource quality, leading to diminishing returns and a rising “real” (inflation adjusted) cost of production. This situation is referred to as declining Energy Return on Energy Invested (EROEI)
The reason for the problem of diminishing returns is because when a producer decides to extract oil, or gas or coal, the producer looks for the cheapest easiest to extract resource first. It is only when this resource is depleted that the producer seek locations where more expensive, harder to extract resource is available. Thus over time, the inflation adjusted cost of extracting a resource tends to increase.
The issue of diminishing returns exists for any kind of resource. It exists for uranium extraction, gold copper and other kinds of metal as we need more oil in extraction and processing as we go deeper to find ore that is mixed with a higher proportion of waste products.
The problem of diminishing returns also holds for renewables. The first bio fuel developed was ethanol from corn, since the process of making alcohol has been known for ages. Newer methods such as ethanol from biomass and bio fuel from algae tend to be more expensive. Accordingly when we add new biofuel production, it is likely to be more expensive and if we want it, we need increasingly high subsidies.
Wind energy where Sri Lanka is trying to embark on is also subject to diminishing returns. Onshore wind was developed first and is far less expensive than offshore wind, which was developed later. Early units of wind added to an electric grid do not disturb the electric grid to a great extent. Later units of wind energy add increasingly large costs: long distance transmission lines, electrical storage and other balancing –something generally overlooked in making cost analyses.
Shale Oil
Shale oil also referred to as “Tight Oil” according to the IEA is the oil savior of the US and the best known examples are the Bakken and Eagle Ford.
It has been reported that drilling wells in the Bakken already seems to be reaching diminishing returns. The choicest locations appear to have been drilled first, and the locations being drilled now give poorer results as average well in Bakken now requires a price of US$ 80 to 90 barrels, which is closer to the recent selling price.
Oil extracting cost growth rate
Bemstein Research recently published information showing that the marginal cost of oil production was US $ 92 barrel in 2011 for non OPEC countries, non Former Soviet Union oil producers at the 90 percentile of production The cost is increasing at 14 % per year( or about 12 % a year in inflation adjusted terms)
If we take $92 barrel cost in 2011 at the 90thpercentile of production and increase it by 7% a year the real cost will be $169 per barrel in 2020.and $467 a barrel in 2035.
IEA WEO 2012
It is also recorded that IEA has not analyzed three more issues in a realistic manner.
w Rising Real Need for Fuels : the analyses of real need for fuels according to the changing economic factors have not been attempted. The need for fossil fuel will rise with increase in infrastructure such as roads bridges etc, building of schools, hospitals etc. Most of these fuel services will need to come from fossil fuels rather than renewables. Renewables especially from biological sources are limited to the needs of 7 billion humans.
