Shell Oil to drill less in the Arctic than planned

Shell Oil company will be doing less drilling in the Arctic this summer than it originally planned to.
Company spokesman  Curtis Smith says lingering sea ice and logistical challenges have shrunk their window of opportunity to work.
He said right now, the main goal is to finish two wells, and start some others that they hope to complete next year.
They had planned to drill ten wells over a two year period.
Shell has invested four and a half billion dollars on the project to date.
