Coast Guard and BP admit ‘MYSTERIOUS second pipe’ stuck in BOP; Experts say indicates casing ‘dislodged’ (VIDEO, PHOTO)

Discovery of second pipe in Deepwater Horizon riser stirs debate among experts, New Orleans Times Picayune, July 9, 2010:

Article Excerpts

For the first time Friday, the Coast Guard and BP acknowledged that a mysterious second pipe, wedged next to the drill pipe. “We found there was actually two sets of drill pipe there,” said retired Adm.

While Allen said he believes the second pipe fell from above, some experts have advanced another explanation. They believe poorly cemented casings — tubes that are supposed to form solid walls down thousands of feet of the well bore — may have been dislodged by the blast of natural gas that shot up out of the well and above the sea floor.

If that’s what happened, the piece of pipe would have gone into the blowout preventer, the 450-ton tower of valves and pistons that sits on top of the well head and is supposed to shut off the well in an emergency. …

The Coast Guard’s acknowledgement [sic] of the two metal tubes Friday — and a subsequent reference by BP to its plans to tie the two pipes together as the company installs a new oil collection system over the shaved-off riser — actually comes more than a month after the Department of Energy noted the existence of two pipes using special imaging technology. At the time, BP dismissed the Energy findings as “impossible” because only one pipe in sections was used for drilling, a Tribune News Service story reported last month.

Oil industry expert Matt Simmons  says the second pipe is lodged in the BOP after “tremendous pressures” from the blast ruptured the well casing. This ejected part of the casing through 50 feet of steel inside the BOP.

Matt Simmons: There’s now sufficient scientific evidence… the government finally did, i think, subsea sonar imaging at the end of last week about the actual BOP.

And coming up through five stories of steel were two shafts of the casing.

Which really indicates that [the casing] must have come out at such tremendous pressures.

If the well casing has come up through the BOP, the relief wells are unlikely to work. For more information on the relief wells chances of success with a ruptured casing, see:
