The AP reports, "With engineers only feet away from completing a pair of them they're now wrestling with how exactly to use them."
BP Senior VP Kent Wells said the kill may be attempted through the failed blowout preventer via a surface ship, rather than wait for the relief well's planned completion later this month.
The AP notes, "BP has never before indicated it might forgo use of the relief well altogether in direct attempts to plug the leak."
"Precisely what the relief wells will do remains to be seen given what we learn from the static kill," BP spokesman Daren Beaudo said. "Can't predict it for certain."
