The Oil Drum staff wishes a Merry Christmas to all in our readership community. We are on a brief hiatus in this period, and will be back with our regular publications early in the new year. In the meantime we present the top 10 of best read Oil Drum posts in 2012. The first in this series is an analysis by Heading Out discussing the report by Leonardo Maugeri on future oil production, originally published in July 2012.

The Tech Talks of the last few months have followed a path of looking in a relatively realistic manner at crude oil production with emphasis on that coming from the United States and Russia, as well as Saudi Arabia, the current focus of my weekly pieces. An earlier piece looked at a Citigroup report of considerable optimism, and the post explained why, in reality, it is impractical to anticipate much increase in US production this decade. Since then, after reviewing the production from Russia, several posts have shown why the current lead in Russian daily crude oil production is likely to be soon over and then decline, as the oil companies are not bringing new fields on line as fast as the old ones are running out. Saudi Arabia, as the current posts are in the process of explaining, is unlikely to increase production much beyond 10 mbd, since Ghawar, the major field on which its current production level is built, is reaching the end of its major contribution, though it will continue to produce at a lower rate into the future. The bottom line, at least to date, is that there is no evidence from the top three producers that their production will be even close, in total, to current levels by the end of the decade.

So, (h/t Leanan) there now comes an Energy Study from Harvard which boldly states that this is rubbish - that by 2020, global production will be at 110.6 mbd and these concerns that most of us have at The Oil Drum (inter alia) are chimeras of the imagination.

With the possibility that demand for Iranian oil may fall below 1 million barrels a day (mbd) as sanctions continue to bite, Iran has announced that it wants OPEC to cut back production to the agreed quotas, rather than the overall additional 1 mbd that is actually being produced and sold. Such a move would, of course, make it more difficult for those customers who have found a way to replace Iranian oil, and perhaps incline them more toward disregarding the embargo.

OPEC has just released their December Monthly Oil Market Report (MOMR) in which they anticipate that earlier projections for 2013 oil demand growth will still be valid at 0.8 mbd. (Though they note that December 2012 growth y-o-y was at 1.0 mbd as the US economy continued to improve). They expect that all of this increase will be met by non-OPEC increases in supply, and that demand for OPEC oil may even drop 0.4 mbd. Part of that projection continues to rely on increased US crude production, and the EIA TWIP of December 5th had the latest chart showing that projected growth, based on the newly released Annual Energy Outlook 2013.

As a footnote to that graph, the Alyeska pipeline pumped an average of 582,755 bd in November, which brings the annual average up to 544, 625 bd. It is clear from looking at that plot that the gains in production are assumed to come from increased production of the "tight" oil deposits that have produced the overall gains achieved to date. The optimism of this projection goes a little beyond the levels that I anticipate will be achieved.

This is a guest post by Stephen Sorrell, senior lecturer Science and Technology Policy Research, Sussex Energy Group, and lead author of the UKERC Global Oil Depletion report, and Christophe McGlade, doctoral researcher at the UCL Energy Institute. This post was slightly revised by the authors and updated here on 25/07/2012. Please see paragrapghs 8 and 9 below the fold for the updated text.

Commentary on: Oil: 'The Next Revolution: The Unprecedented Upsurge of Oil Production Capacity and What it Means for the World' - Leonardo Maugeri, Belfer Center for Science and International Affairs, Harvard University

Summary Maugeri's analysis and conclusions are critically dependent upon the decline rates applied to existing and future fields, and yet he does not explicitly say what these decline rates will be. However, Maugeri’s assumptions can be derived from his Table 2, which projects gross and net capacity additions over the period to 2020. Doing so suggests he uses an average annual decline rate for all fields of 1.6% over this period, which is less than half of the IEA and CERA estimates for 2008 (4.1%/year and 4.5%/year respectively). The discrepancy is even greater since the IEA and other analysts project an increase in average decline rates over the 2011-20 period. If we replace Maugeri’s 1.6% decline rate assumption with the IEA estimate of 4.1%, the projected loss of production capacity over the period to 2020 increases from 11 mb/d to 26.5 mb/d. In turn, the projected global production capacity in 2020 reduces from 110.6 mb/d to 95.1mb/d (a reduction of 14%). Since average decline rates would be expected to increase over this period, this projection must be considered optimistic.

There are many unintended consequences as fuel supplies become more scarce and expensive. (With a h/t to Rune Likvern), I see that those Greeks who are being starved of affordable fuel are starting to chop trees down for warmth and income. This sort of desperation has devastated the countryside all over Albania, Africa, and Asia, and it is extremely difficult to stop the practice from spreading or to recover from it. The world expects that fuel must be available at an affordable price, and one of the ongoing questions is whether it will continue to be.

In that regard, BP has just released its Annual Energy Outlook 2030, examining how the world energy supply, and mix, will change in the years up to 2030. The booklet is an update from the study released last year, and reviewed at the time. This year the introductory speech by Bob Dudley focused on energy demand in China and India, Middle East exports, and transport fuel demand. BP sees overall energy demand growing some 40% over the next two decades, with virtually all growth coming from the developing countries. More than half will come from China and India alone. And of that energy, they anticipate that the supply will break out as follows:
