The westernmost peninsula of Eurasia, Europe is bordered by the Arctic Ocean to the north, the Black Sea to the southeast, the Mediterranean Sea to the south and the Atlantic Ocean to the west. The economic and political association of 27 European member states, the European Union (EU) has developed a single market through which a standardized system of laws apply, and under this union, sixteen member states have adopted the euro as its common currency. In 2006, the EU had a gross inland energy consumption of 1,825 million tonnes of oil equivalent, with nuclear energy as the primary source of energy produced in the region. Currently, the EU imports around 82% of its oil and 57% of its natural gas resources.
Geophysicists play an important role in the oil and gas industry as they help find underground oil and gas deposits by creating a clear picture of what is below the earth’s surface. Using physical methods (seismic, gravitational, magnetic, electric) they measure the physical properties of subsurface earth to detect or infer the presence of oil or gas. The most common way to create a clear picture of the earth's subsurface is through the seismic method whereby shock waves that are set off at the surface resonate through the earth, and the returning echo can be used to tell what is beneath the surface. Geophysicists are usually classified into three categories: acquisition, processing and interpretation. A strong geoscience, physics, or mathematics background is necessary for a career in geophysics.
