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.
Wireline logging is used to obtain a record of the geophysical properties of a formation. This data is obtained by lowering a logging tool into a well on the end of a wireline (an electric cable with the ability to transmit data). The data gathered by the logging tools helps to better understand the capabilities of a well and to help make decisions about drilling or production operations.
