Shell's entire venture to explore for oil in Alaskan waters has been a disaster from start to finish, leading to many to begin to question whether they are in fact prepared to operate in the Arctic.

Ken Salazar, US Secretary of the Interior, has ordered a 60 day internal inspection of Shell's activities in the Arctic to try and determine whether or not it is capable of such exercises.

A negative outcome could see Shell have its Arctic drilling permit revoked.
