According to this article, Shell Oil Company has announced that it will no longer seek to drill for oil this summer in certain parts of the United States: "Shell Oil Company has announced it must scrap efforts to drill for oil this summer in the Arctic Ocean off the northern coast of Alaska. The decision comes following a ruling by the EPA’s Environmental Appeals Board to withhold critical air permits. The move has angered some in Congress and triggered a flurry of legislation aimed at stripping the EPA of its oil drilling oversight." That's after spending nearly $4 billion on the project.
