Canada currently requires that companies operating in the Arctic have to drill relief wells in the same season as the primary well.

As we’re seeing from the BP Gulf oil disaster, relief wells are the only solution with a high probability of success in the event of a major leak. But they take about 3 months to drill, and add cost to the operation (though I don’t know how much added cost). In other words, the oil wouldn’t be as cheap to extract if a relief well were required.

Given the environmental disaster created by the Gulf oil spill, do you think relief wells should be a requirement for all offshore drilling operations, or would this be an excessive requirement?
