The increase in the price of crude continues to activate new drilling. Interest in deep water resources has also continued to increase. New discoveries (in Brazil and along the African coasts) have increased the tenders for projects, especially in countries with heavy consumption, such as China and India.
Exploration in search of shale gas continued to advance throughout the world in 2011. In Europe, expectations in Poland, among other countries, continue to be favourable (estimated at 5300 bcm).
