Although the massive oil leak in the Gulf of Mexico has been reduced to a trickle based on successful attempts to finally cap the well, the permanent solution to the crisis will only arrive upon completion of the relief wells that BP is currently drilling.  The company expects the relief well to permanently end the flow of oil by mid-August.  Given the fact that relief wells represent the most certain way to kill a troubled well, should oil exploration firms be required to preemptively drill relief wells along with exploration wells?

Making preemptive relief wells a required part of deep sea oil exploration was the subject of an opinion article in today’s Wall Street Journal.  Michio Kaku, a professor of theoretical physics at City College of New York, makes the following recommendation:

In the future there should be much tighter controls on deep-water drilling, and there should be redundant systems on hand so that the well can be capped or siphoned immediately if the blowout preventer fails. Perhaps relief wells should be drilled simultaneously with the main well, since they are the gold standard for stopping oil leaks and work nearly without fail. There also has to be a standby fleet of ships with skimmers, centrifugal pumps and booms ready to handle oil once it is leaked.

One obvious problem with the idea of automatically drilling a relief well is the high cost of such a preventative step.  Drilling additional relief wells also comes with its own set of risks and requires additional drilling platforms which are extremely costly to operate.  While one may think that offshore drilling contractors would jump for joy at the thought of the additional rigs that would be required under such a policy, in reality the step would make exploration uneconomical.  Furthermore, there is clear evidence indicating that faulty well design was used for the Macondo well and it may be better to tighten regulations specifying the nature of drilling techniques rather than mandating preemptive relief  wells.
