What the impacts on the current revolution market of the shale gas?

The development of technologies for production of shale gas has been considered a revolution for business and economics of natural gas. Many agents and even the U.S. government believe that unlinking price of natural gas from price of oil in the United States is a structural phenomenon that reflects the new technological and geological context of the natural gas industry. There is a perception that the technological revolution of shale gas will affect permanently not only the U.S. gas industry, but also the global gas trade. Those believing this structural show the following arguments to support this view:

  • The current shale gas resources in the USA are equivalent to 3.5 times the volume of all proved reserves in the USA today. Moreover, the availability of shale gas resources is not restricted to USA. A recent survey conducted by Department of Energy (DOE) has pointed out the existence of large volumes of shale gas resources in 48 sedimentary basins in 32 countries, including Brazil, Argentina, Bolivia, Uruguay and Paraguay.
  • The technological learning process in the last 10 years has reduced dramatically the cost of producing shale gas. The main innovations were: i) reduction of the time for drilling wells, ii) improvement of horizontal drilling techniques, iii) improvement of geological knowledge in production areas, iv) development of hydraulic fracturing technology and standardization of equipment. These innovations have reduced production costs to less than US$ 3 per MMBtu, in the best producing areas. Continue lendo »

Fukushima Nuclear Accident: a dilemma for the world energy planning

The accident in Fukushima Daiichi power plant, located about 250 km from Tokyo, and the classification of the French Nuclear Safety Authority (ASN) on the explosions occurred in the Japanese generation plant that reached the level 6 (serious accident), in an international scale for nuclear events until level 7 [*] engraved energy experts worldwide. That adds a strong element of uncertainty for the global nuclear industry.

The INES level (6) means serious accident, stating that there was release of radioactive material and as consequences the adoption of measures to protect the population in the affected area.  This reflects the world public opinion, causing major concerns and pressure against the generation of electricity through this source.

Shortly after the accident, some experts, under the impact of the tragic news and images in real time, agreed with the thesis that the revival of the nuclear industry was being aborted.  Perhaps the question not discussed is: Without using nuclear energy, how can we meet the increasing consumption of energy required by societies in the coming years in a context of reducing emissions of greenhouse gases?

A future agenda for biofuels policy in Brazil

In biofuels on 17/01/2011 at 00:30

The Brazilian Association for the Study of Energy – AB3E – held on December 14, 2010, in Rio de Janeiro, a seminar to discuss the agenda for the Brazilian energy policy for the next administration. In the specific panel, where agenda for biofuels was discussed, there were two approaches: one from representative of Petrobras, Eduardo Correia, Competitive Strategy area, who identified a number of critical uncertainties that influence strongly the biofuels market, developing initially from these uncertainties four exploratory scenarios and selecting two scenarios for the next 20 years, and the other one from professor José Vitor Bomtempo, Energy Economics Group, who assessed the future of the biofuels industry in a strategic approach with assumptions that break current paradigms.

This article presents the considerations from these experts and question on the topic that will surely be discussed by energy policy agenda developers for future years. Continue lendo »
