It raises the whole question of why the temporary fix of the capping of the upper well was never even tried, knowing there was a strong probability that the 13,000 foot wells had been damaged by the initial eruption and violent racing oil and gas and debris pressing depths in the bowels of the earth.
It was already clear evidence that the envelope had been violated. Although not mentioned in news reports of general interest, a point of view from the floor of the sea taken by a camera on the ROV a bone, a remotely operated robot submersibles monitoring the wellhead, and the display on the site of BP, beginning at approximately 2: 48:40 Central Time on June 16, showed clouds of mud looking for water suddenly emerge and begin to obstruct the view of the ocean floor. Part of the floating material was colored and could be pushed to the mud by leaking methane gas. Some looked decidedly dark brown, like the oil was seen coming from the top of the shutter (BOP).
A second rover, Viking Poseidon an ROV, which was not included in the live cams posted on BP’s public access on June 16 but could be seen here, also showed a large cloud of billowing brown churning up the sea floor at the beginning of 3:06:00, Central Time. Other pictures showed rising bubbles form the floor of the sea – something that had not been seen previously.
If any of these video images are actually showing oil or gas out of the ground around the wellhead, it could mean only one thing: that the coating was severely violated somewhere underground, and there is no way to stop any flow of oil, or even obtain all the above well. That would certainly explain why the pressure at the wellhead blocked stabilized at approximately 6750 psi. This is well below the 8000-9000 “psi” was until Friday the government and BP said would be full pressure, and is even below the new target for improvement mentioned retired Admiral Thad Allen which, on June 16 reported a more modest 7,500 psi would be good. (Claim of Allen that the pressure in the underground tank, 13,000 feet below the flow of the sea, could be lower by 15-20%, explaining the low readings at the wellhead due to 1-2 million barrels that have already escaped, is patently absurd. We’re talking about a tank said to contain over 1 billion barrels of oil! two million barrels would be only 0.2% of this amount. In addition, the shell n is not a rigid container such as an oil reservoir. The pressure is caused by the weight of the crust 2.5 miles and miles of water sitting on it, which will continue to press with the same force, however it remains still plenty of oil in the reservoir. There may be a slight decrease of the oil out, but not by that amount.
