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.
MWD/LWD refer to measurement and logging while drilling. The MWD operator measures the path of the wellbore while it is being drilled, and this data is then used to help plan the direction that the well will be drilled. LWD, while sometimes used interchangeably with MWD, refers more to the process of obtaining information about the rock being drilled, while MWD is more about the drilling operation.
