HOUSTON, July 19 BP Plc (BP.L) (BP.N) said
seepage nearly 2 miles (3 km) from its ruptured Macondo well in
the Gulf of Mexico is natural and is unrelated to the oil leak,
a spokesman said.
"Scientists have concluded that the seep was naturally
occurring," BP spokesman Mark Proegler told Reuters.
Another spokesman, Daren Beaudo, said BP was testing two
sets of bubbles rising from the top of the wellhead. One was a
"slow-developing gas bubble" on the seafloor near the top of
the well. The other, which BP disclosed on Saturday, also was
near the top of the well where a cap is shutting in all oil
Beaudo said it is possible the bubbles are nitrogen, which
can form at the seabed atop deepwater wells, rather than
natural gas, which could signal a leak in the well. BP has
taken samples of both bubbles for testing.
"We will communicate results when testing's complete," he
