Deepwater trouble on the horizon: oil discovered floating near source of Gulf of Mexico spill

MOBILE, Alabama -- Oil is once again fouling the Gulf of Mexico around the Deepwater Horizon well, which was capped a little over a year ago.
Tuesday afternoon, hundreds of small, circular patches of oily sheen dotted the surface within a mile of the wellhead. With just a bare sheen present over about a quarter-mile, the scene was a far cry from the massive slick that covered the Gulf last summer.
Floating in a boat near the well site, Press-Register reporters watched blobs of oil rise to the surface and bloom into iridescent yellow patches. Those patches quickly expanded into rainbow sheens 4 to 5 feet across.
Each expanding bloom released a pronounced and pungent petroleum smell. Most of the oil was located in a patch about 50 yards wide and a quarter of a mile long.
The source of the oil was unclear, but a chemical analysis by Louisiana State University scientists confirmed that it was a sweet Louisiana crude, and could possibly be from BP PLC’s well.
The oil could be flowing from a natural seep on the seafloor near the wellhead, experts said. Other possibilities include oil trapped within the wreckage of the Deepwater Horizon drilling rig, or oil deposited on the bottom during the spill that is slowly working its way to the surface.
The most troubling possibility, according to petroleum engineers, is that oil is leaking up through the seafloor surrounding the sealed well pipe.
Last week, in response to Internet postings by lawyers and environmental groups describing a leak, BP issued a blanket denial, stating, “None of this is true.”
Subsequently, the Gulf Restoration Network and Bonny Schumaker with On Wings of Care took aerial photographs of circles of oil floating in the area Friday. The group filed a report with the National Response Center, the federal clearinghouse for pollution incidents.

Chemical analysis of the Press-Register's samples by LSU scientists found that the oil could be from the BP well, but results were not conclusive. BP meanwhile said no oil was present when the company flew over the area Saturday. Watch video
“We stand by what we said last week, neither BP nor the Coast Guard has seen any scientific evidence that oil is leaking from the Macondo well, which was permanently sealed almost a year ago,” BP spokesman Justin Saia wrote in an emailed statement Wednesday. “We welcome the opportunity to test any hydrocarbon sheens detected in the area of the well.”
U.S. Coast Guard officials said Wednesday that the earlier reports were investigated by flying over the site.
The Coast Guard determined that the reported sheens resulted from “natural seeps” and permitted pollution releases at other oil drilling sites. Coast Guard officials did not elaborate when asked how those determinations were made, and said that no boats had visited the well location since the reports were filed.
“I think the primary source with high probability is associated with the Macondo well,” said Robert Bea, an internationally prominent petroleum engineer and professor emeritus at the Berkeley campus of the University of California. Bea responded to Press-Register questions via email after examining photographs taken by the newspaper.
“Perhaps connections that developed between the well annulus (outside the casing), the reservoir sands about 17,000 feet below the seafloor, and the natural seep fault features” could provide a pathway for oil to move from deep underground to the seafloor, Bea said.
“Looks suspicious. The point of surfacing about 1 mile from the well is about the point that the oil should show up, given the seafloor at 5,000 feet ... natural circulation currents would cause the drift,” Bea said. “A Remote Operated Vehicle (ROV) could be used to ‘back track’ the oil that is rising to the surface to determine the source. This should be a first order of business to confirm the source.”

PORT FOURCHON, La. (AP) - BP PLC is sending cleanup crews back to Fourchon (foo-SHONH') Beach because erosion from Tropical Storm Lee unearthed miles of tar balls, tar mats and abandoned cleanup equipment left from last year's oil spill.
Company spokesman Curtis Thomas tells The Courier (http://bit.ly/q62h7J ) that 90 workers and 17 technicians will clean the beach, with the work going on seven days a week.
In addition to the old oil, the erosion uncovered PVC pipes used to secure boom and snares used to absorb oil.
The oil was found by field inspector Forrest Travirca of the Edward Wisner Donation - a private land trust that owns about 9.5 miles of Fourchon Beach. He estimates that eight miles of the beach are affected.
He found the oil while checking for damage from Tropical Storm Lee.

No end in sight for oil in the Gulf of Mexico
Fresh oil seepages raise questions about further problems with BP's damaged oil well.

Fifteen months after BP's crippled Macondo Well in the Gulf of Mexico caused one of the worst environmental disasters in US history, oil and oil sheen covering several square kilometers of water are surfacing not far from BP's well.
Al Jazeera flew to the area on Sunday, September 11, and spotted a swath of silvery oil sheen, approximately 7 km long and 10 to 50 meters wide, at a location roughly 19 km northeast of the now-capped Macondo 252 well.
According to oil trackers with the organisation On Wings of Care, who have been monitoring the new oil since early August, rainbow-tinted slicks and thicker globs of oil have been consistently visible in the area.
"BP and NOAA [National Oceanographic and Atmospheric Administration] have had all these ships out there doing grid searches looking at things, so hopefully now they'll take a look at this," Bonny Schumaker, president and pilot of On Wings of Care, told Al Jazeera while flying over the oil.
Schumaker has logged approximately 500 hours of flight time monitoring the area around the Macondo well for oil, and has flown scientists from NASA, USGS, and oil chemistry scientists to observe conditions resulting from BP's oil disaster that began in April 2010.
Edward Overton, a professor emeritus at Louisiana State University's environmental sciences department, examined data from recent samples taken of the new oil.
Overton, who is also a National Oceanic and Atmospheric Administration (NOAA) contractor, told Al Jazeera, "After examining the data, I think it's a dead ringer for the MC252 [Macondo Well] oil, as good a match as I've seen".
He explained that the samples were analysed and compared to "the known Macondo oil fingerprint, and it was a very, very close match".
While not ruling out the possibility that oil could be seeping out of the giant reservoir, which would be the worst-case scenario, Overton believes the oil currently reaching the surface is likely from oil that was trapped in the damaged rigging on the seafloor.
He said the oil could either be leaking from the broken riser pipe that connected the Deepwater Horizon to the well, or that oil is leaking from the Deepwater Horizon itself.
