The view from space indicates that the oil may be leaking at a rate of
barrels a day, dwarfing the figure of 5,000 barrels that US officials
the British oil giant BP have used in recent days.
That would mean that some nine million gallons may already have escaped
the underwater well following the April 20 explosion that killed 11
workers. It suggests the disaster will almost certainly prove greater

which leased the rig and owned the oil rights, had downplayed the
danger of any spill - predicting "no significant adverse impact" -
when it submitted its exploration plan last year.
The scale of the looming catastrophe was still unclear yesterday as
winds hampered an emergency operation to mop up the 2,200 sq mile
being blown towards the coast of five US states.
Even BP has acknowledged that the 5,000-barrels-a-day figure for the
already a five-fold increase on the 1,000 barrels that it initially
is only a "guesstimate". The Coastguard has also said that that
leak rate could turn out to be much greater than 5,000 barrels.
The implications of the higher figures for the fishing waters, wildlife
beaches of the Gulf - and the residents whose livelihoods depend upon
are potentially devastating.
John Amos, director of SkyTruth, a satellite data monitoring outfit that
supplies analysis to environmental groups, told The Sunday
that the images and information made public by BP indicated that the
was made up of at least six million gallons of oil.
"That is a conservative estimate and it would mean that oil is leaking
a rate of 20,000 barrels a day," he said. "That's a real
eye-opener. And I believe the true figure is significantly higher."
Ian MacDonald, a Florida professor of oceanography who tracks maritime
seepage, estimated that more than nine million gallons may already
escaped into the sea on the basis of higher industry estimates of the
of leakage. BP engineers have been desperately and unsuccessfully
use unmanned submarines to initiate a failed switch-off device on the
about a mile beneath the surface of the water.
In the absence of such a quick-fix solution, the company is pursuing two
remedies to stop the leak, but both will take weeks or months.
In the medium-term, the company is hoping to cover the leaks with
steel domes that would capture the escaping oil and funnel it back to a
at the surface through pipes. The technology has been deployed for
much shallower depths but has never been used for a deep-sea spill.
It has also dispatched a drill ship to the area to begin digging a

well, but the process will take at least three months and possibly
At the same time, investigations have been launched into the two crucial
failures - why the rig exploded and then why the automatic switch-off
did not then activate. Oil industry analysts believe the explosion was
caused by a "blow-back" when a pressure surge thrust natural gas
up to the rig platform. One area under focus is a recently-completed
cementing operation by the company Haliburton, which was intended to
oil and gas from escaping by filling gaps between the outside of pipes
the inside of the hole drilled into the ocean floor into which they
According to a 2007 US government report, cementing was a factor in 18
well blow-outs in the Gulf of Mexico over a 14-year period. And
investigators have also been told that cementing was a likely cause of
major 10-week blow-out in the Timor Sea off Australia last year.
Haliburton has declined to comment while the cause of the accident is
investigated and lawsuits are pending.
The second disastrous failure occurred when the rig's "blowout
