Energy question of the week: Does the oil spill in the Gulf of Mexico mean the end of deep sea drilling?
Even if BP itself may well be in difficulty because of the disaster, the global oil industry will hardly give up exploring deep-sea oil reserves. Even US President Barack Obama failed to enforce a temporary stop to drilling at a New Orleans court. Thirty-two oil companies contested the stop order, and although the White House may well appeal against the decision, the outcome of such an appeal is far from certain.

An end to drilling in the North Sea?
Deep sea drilling is going on at around 350 sites in European waters. Following the disaster in the Gulf, EU Energy Commissioner Günther Oettinger has decided not to grant any new drilling licenses – but only for the time being, until the causes of the Deepwater Horizon spill have been determined. European oil companies are pushing to explore and exploit new oil fields, since reserves, especially in the North Sea and North Atlantic, are dwindling.
There is certainly a good chance that safety measures will be improved on deep-sea platforms worldwide. But it is senseless to propose that oil companies from the industrialised West should shut down their operations, according to analyst Volker Steinbach from the Federal Office for Geo-sciences and Resources (Bundesanstalt für Geowissenschaften und Rohstoffe; BGR) in Hanover. "In such a case I can only imagine that China would immediately snap up the licenses," he says. And it seems pretty doubtful that China would implement similarly stringent safety standards.
Brazil's oil reserves are even deeper than the Gulf of Mexico's
The emerging economy of Brazil is similarly unlikely to abandon its recently discovered reserves, off the coast northeast of Rio de Janeiro. Reserves in the Pré Sal area are estimated to be around 55 billion barrels (each barrel is 159 litres). These fields will be opened up in the near future, and could make Brazil the fourth largest oil producing country in the world. But such business opportunities are always accompanied by risk. In order to exploit these fields, Brazil’s Petrobras will have to drill at an ocean depth of 2000 metres and sink its wells seven kilometres deep. An even bigger technical challenge that that of the Gulf of Mexico.
The DLR Energy question of the week in 'The future of energy' Year of Science
The Federal Ministry of Education and Research (BMBF) has given the Year of Science 2010 the motto 'The future of energy'. For this reason the science journalist Jan Oliver Löfken will this year answer a question on the subject of energy in his blog each week. Do you have a question about how our energy supply might look in the future? Or do you want to know, for example, how a wave power plant works and how it can efficiently generate electricity? Then send us your question by email. Science journalist Jan Oliver Löfken will investigate the answers and publish them each week in this blog.
