Peak cheap oil is an incontrovertible fact  

I'm always a little dubious about Ambrose Evans-Pritchard but this column (wondering about the hype over Maugeri's mistaken analysis of peak oil) is worth a read - Peak cheap oil is an incontrovertible fact.

Brent crude jumped to $115 a barrel last week. Petrol costs in Germany and across much of Europe are now at record levels in local currencies. Diesel is above the political pain threshold of $4 a gallon in the US, hence reports circulating last week that the International Energy Agency (IEA) is preparing to release strategic reserves.

Barclays Capital expects a “monster” effect this quarter as the crude market tightens by 2.4m barrels a day (bpd), with little extra supply in sight. Goldman Sachs said the industry is chronically incapable of meeting global needs. “It is only a matter of time before inventories and OPEC spare capacity become effectively exhausted, requiring higher oil prices to restrain demand,” said its oil guru David Greely.

This is a remarkable state of affairs given the world economy is close to a double-dip slump right now, the latest relapse in our contained global depression. ...

So we face a world where Brent crude trades at over $100 even in recession. Fears of an Israeli strike on Iran may have spiked the price a bit, though Intrade’s contract for an attack is well below levels earlier this year. Iranian sanctions may have cut supply by more than the extra 900,000 bpd pumped by Saudi Arabia. Japan’s increased reliance on oil since switching off most of its nuclear reactors has played its part.

Yet the deeper force at work is the relentless fall in output from the North Sea and the Gulf of Mexico, endless disappointment in Russia because of Kremlin pricing policies, and the escalating cost of extraction from deep sea fields.

Nothing has really changed since the IEA warned four years ago that the world must invest $20 trillion in energy projects over the next 25 years to feed the industrial revolutions of Asia and head off an almighty crunch. The urgency has merely been disguised by the Long Slump.

We learned in the 2006-2008 blow-off that China is now the key driver of global oil prices, with consumption rising each year by 0.5m bpd -- now a total 9.2m bpd in a world market of 90m bpd. Demand is broadly flat in Europe and America.

So what will happen when China latest spending blitz gains traction? The regions have unveiled a colossal new spree on airports, roads, aeronautics, and industrial parks: a purported $240bn each for Tianjin and Chongqing, $160bn for Guangdong, $130bn for Changsha, and so forth. Sleepy Guizhou has trumped them all with $470bn. Your mind goes numb.

What will happen too when car sales in China surpass 20m next year, as expected by the China Association of Automobile Manufacturers? ...

World opinion has swung a little too cavalierly from the Peak Oil panic four years ago to a new consensus that America’s shale revolution -- and what it promises for China, Argentina, and Europe -- has largely solved the problem.

Much has been made of “Oil: The Next Revolution” by Harvard’s Leonardo Maugeri, who forecasts an era of bountiful supply and cheap oil as global output capacity rises by almost 18m bpd to 110m bpd by 2020.

Sadad al-Huseini, former vice-president of Saudi Aramco, has a written a testy rebuttal, arguing that Dr Maugeri assumes a global decline rate of 2pc a year from oil fields compared to the IEA’s estimate of 6.7pc. There alone lies the gap between crunch and glut. ...

The shale revolution has profound implications for America’s role in the world and the global balance of power, but let us not get carried away. Oil experts noticed how many crews in the Bakken field were told to stand down when crude prices dipped earlier this summer. “Supposedly cheap shale turned out to be rather expensive shale in that, as soon as Brent fell to $90 per barrel, a large proportion of US shale oil in key regions seemed to lose all its rent,” said Paul Horsnell from Barclays Capital.

Leonardo Maugeri's recent paper Oil: The Next Revolution on the presumed future abundance of oil supplies rejects the pessimistic outlook of limited increases in oil capacity over the next decade. It suggests global oil capacity will exceed 110 million barrels per day by the end of the decade, putting an immediate end to concerns regarding constrained long-term oil supplies. This conclusion is based on an assessment of new projects with a reported capacity of 49 million b/d before a downward adjustment to 29 million b/d to allow for completion risks and reserves depletion. Maugeri holds two PhDs, one in Political Science and one in Economics, and has extensive executive experience with ENI in strategies and developments and in petrochemicals.

In putting forth this optimistic thesis, Maugeri apparently sets aside a variety of technical realities, including the difference between natural gas liquids (NGLs) and conventional oil, reserves depletion versus capacity declines, and proven reserves as opposed to speculative resources.

The report mixes NGLs, which feed petrochemicals and domestic or industrial fuel applications, with conventional oil, which is the main source for transportation fuels. When fractionated, NGLs yield propane, butane and light naphtha. These products cannot replace oil distillates such as gasoline, diesel or jet fuel.

For example, NGLs grew from 7 million b/d in 2003 to an estimated 12 million b/d in 2011 but provided no relief to the demand for transportation fuels, which was surging across those years. The growth in NGLs is now forecast by the IEA to reach an ambitious 20 million b/d by 2030. Impressive as this may be, NGLs will remain at best marginally relevant to transportation applications until widespread changes occur in the technology and infrastructure of the auto and trucking industries. Given cost and complexities, there is no evidence that this is likely to happen within this decade.

In regard to capacity declines, the report appears to confuse oil reserves depletion with capacity declines. In the world of petroleum engineering, depletion quantifies residual reserves in the ground, while declines define a reservoir's ability to sustain a given level of production over time. Incremental reserves in modern discoveries are added early in a discovery's life while production declines are a subsequent development related to reservoir factors including changing fluid compositions and diminishing reservoir energy. Maugeri's suggestion that incremental reserves may offset capacity declines mixes up speculative exploration variables with reservoir engineering realities.

The report takes exception to the IEA's 2008 estimate of an average 6.7% global oil capacity decline and offers an equivalent estimate of less than 2% per year. This low estimate is apparently based on the observation of historical production rates from major oil producing countries. It is not clear how the author extracted the convoluted effects of offsetting market volatility, spare capacity utilization, natural production declines, and ongoing new capacity investments from such historical trends.

The IEA’s 2008 study, on the other hand, applies well-established petroleum engineering principles to 800 post-peak fields that make up the majority of global oil supplies. The natural decline rates of these fields were reported to average 3.4% for 54 supergiant fields, 6.5% for scores of giant fields and the 10.4% decline rate for hundreds of large fields. At the IEA's 6.7% level of capacity declines, the current 74 million b/d of conventional oil supplies (which exclude NGLs, biofuels, nonconventionals and various other liquids) would require 5 million b/d of supplemental new capacity annually just to maintain a flat level of supply. Based on these assessments, Maugeri’s 29 million b/d of "risked" new capacity would only replace declines through 2017. Even the full 49 million b/d of new projects would only extend current liquids production on a flat trajectory to 2021.
