Oil prices fluctuate amid tensions over Greenland and North Sea energy summit

Oil prices have been moving up and down recently. They fell on expectations of increased supply, then steadied as concerns about supply from Iran eased.

Much of the focus has shifted to Greenland, where political tensions are creating uncertainty. At the same time, European leaders held an energy summit focused on the North Sea, where a project is underway to capture carbon dioxide and pump it under the seabed.
