I think that in the future, any deep sea drilling should be done when a relief well is ready to go in the case of an accident.

A relief well is a well, so by that logic before drilling a relief well you'd first need to drill a relief well for the relief well, and so on.

Obama’s moratorium on drilling would technically mean no relief well could be drilled.

but it wouldn’t be an open well being pumped. It would be partially completed, and it could be “turned on” in the event the main well was leaking.

Applying logic would show that each would serve as the relief well for the other.
