Norway’s economy is significantly dependent on oil, and starting in 2004, its oil output began to stagnate as the country’s deposits were running dry. However, in 2007, new oil reserves were discovered in the North Sea that could only be fully extracted with an untested, cutting edge technology called Ionic Infusion. The Ionic Infusion method injects saltwater into underwater shale deposits, causing a chemical reaction that activates the oil and makes it extractable. Norwegian oil firms employed this technology to the new deposits in late-2007. Below is Norway’s oil output per capita figures from 2002 to 2018. Norway’s population is assumed to have stayed constant during 2002-2018. Based on this information and the data & chart below, please explain the changes in Norway’s oil sector productivity from 2002-2018, including at least three concepts related to economic and productivity growth over time.
