No Peak Oil in Sight: We’ve Got an Unprecedented Upsurge in Global Oil Production Underway

junho 26, 2012

New interesting post from Prof. Mark Perry (mjperry.blogspot.com):

No Peak Oil in Sight: We’ve Got an Unprecedented Upsurge in Global Oil Production Underway

 

The global oil boom underway represents the most significant increase in any decade since the 1980s.

In the tradition of resource economist Julian Simon, here are some of the conclusions and predictions from new research just published by Harvard Research Fellow Leonardo Maugeri, titled “Oil: The Next Revolution; The Unprecedented Upsurge of Oil Production Capacity””

1. Contrary to what most people believe, oil is not in short supply and oil supply capacity is growing worldwide at such an unprecedented level that it might outpace consumption. From a purely physical point of view, there are huge volumes of conventional and unconventional oils still to be developed, with no “peak-oil” in sight. The full deployment of the world’s oil potential depends only on price, technology, and political factors. More than 80 percent of the additional production under development globally appears to be profitable with a price of oil higher than $70 per barrel.

2. The shale/tight oil boom in the United States is not a temporary bubble, but the most important revolution in the oil sector in decades. It will probably trigger worldwide emulation, although the U.S. boom is difficult to be replicated given the unique features of the U.S. oil (and gas) arena. Whatever the timing, emulation over the next decades might bear surprising results, given the fact that most shale/tight oil resources in the world are still unknown and untapped. China appears to be the first country to follow the U.S. example. Moreover, the extension of horizontal drilling and hydraulic fracturing combined to conventional oil fields might dramatically increase world’s oil production and revive mature, declining oilfields.

3. In the aggregate, conventional oil production is also growing throughout the world, although some areas (e.g. the North Sea), face an apparently irreversible decline of the production capacity. In most traditional producing countries, old oilfields go through a production revival thanks to better techniques and knowledge, or advanced exploration and production technologies, so far used only in the U.S. and in the North Sea. Huge parts of the world are still relatively unexplored for conventional oil (for example, the Arctic Sea or most of sub-Saharan Africa).

4. Over the next decades, the growing role of unconventional oils will make the Western hemisphere the new center of gravity of oil exploration and production.

5. Based on original, bottom-up, field-by-field analysis of most oil exploration and development projects in the world, this paper suggests that an unrestricted, additional production of more than 49 million barrels per day (mbd) of oil is targeted for 2020, the equivalent of more than half the current world production capacity of 93 mbd.

6. After adjusting this substantial figure considering the risk factors affecting the actual accomplishment of the projects on a country-by-country basis, the additional production that could come by 2020 is about 29 mbd. Factoring in depletion rates of currently producing oilfields and their “reserve growth,” the net additional production capacity by 2020 could be 17.6 mbd, yielding a world oil production capacity of 110.6 mbd by that date – as shown in Figure 1 above. This would represent the most significant increase in any decade since the 1980s.

Collective Intelligence and Neutral Point of View: The Case of Wikipedia

junho 26, 2012

Paper do National Bureau of Economic Research- NBER dos EUA!
“Collective Intelligence and Neutral Point of View: The Case of Wikipedia

Shane Greenstein, Feng Zhu

NBER Working Paper No. 18167
Issued in June 2012
NBER Program(s):   IO   PR

We examine whether collective intelligence helps achieve a neutral point of view using data from a decade of Wikipedia’s articles on US politics. Our null hypothesis builds on Linus’ Law, often expressed as “Given enough eyeballs, all bugs are shallow.” Our findings are consistent with a narrow interpretation of Linus’ Law, namely, a greater number of contributors to an article makes an article more neutral. No evidence supports a broad interpretation of Linus’ Law. Moreover, several empirical facts suggest the law does not shape many articles. The majority of articles receive little attention, and most articles change only mildly from their initial slant.

O que se pode destacar na indústria do smartphone?

junho 22, 2012

O smartphone é o artefato que mais representa hoje a convergência tecnológica, bem como a organizacional: ele conjuga os atributos da telefonia móvel, os serviços da Internet, e os artefatos de computação pessoal.

Mas o que é que se pode destacar na indústria do smartphone, do ponto de vista econômico?

A “Trindade Essencial”: Ecossistema + Plataforma + Arquitetura

junho 13, 2012

O tema da newsletter da Creativante da semana que vem é este => A “Trindade Essencial” = Ecossistema + Plataforma + Arquitetura!

Através deste conceito de “Trindade Essencial“, argumentaremos que não basta ter apenas um “ecossistema” de empresas (como no Porto Digital) para se ter sucesso.  O essencial é que este ecossistema esteja voltado a produzir “plataformas”  de produtos e serviços (de preferência globais), e que estas definam sólidas “arquiteturas de indústrias“, tal como fazem os EUA, e, de modo particular, o Vale do Silício!
