The Leak Is Over: BP, USCG Declare Macondo Well Permanently Sealed

by Miles Wolf Tamboli - The Talk Radio News Service

After five months, the BP Deepwater Macondo Well has finally been permanently sealed.  

“We can now state, definitively, that the Macondo well poses no continuing threat to the Gulf of Mexico,” said National Incident Commander Admiral Thad Allen in a statement released by the Deepwater Horizon Unified Command on Sunday.

Pressure testing was completed early Sunday morning, assuring crews that the well is in fact completely sealed, and that the cement has set.

“This is a significant milestone in the response to the Deepwater Horizon tragedy and is the final step in a complex and unprecedented subsea operation - finally confirming that this well no longer presents a threat to the Gulf of Mexico,” said Tony Hayward, petroleum mogul BP’s group chief executive, in a press release issued Sunday by BP. 

The final plugging of the well was enabled by the drilling of a relief well, which the administration has been touting as the only final answer to the months long leak since the beginning, despite having essentially capped the well with a customized stacking cap in mid July.  The relief well intercepted the Macondo’s annulus last wednesday, and began pumping a cement mixture into the open space on Friday.

The deepwater Macondo well, owned and operated by an amalgam of international corporations - including Britain’s BP and Halliburton, and the Swiss company Transocean - spewed millions of barrels of Sweet Louisiana Crude oil into the Gulf of Mexico after the rig exploded in a string of mishaps that took the lives of 11 workers aboard the Deepwater Horizon rig, and crippled the Gulf Coast’s economy, which relies heavily upon the triumvirate of fishing, tourism, and oil industries.

As of Friday, 39,885 square miles of Gulf of Mexico federal waters remain closed to fishing in response to public health and safety concerns, and approximately 600 miles of coastline are still experiencing some oil impacts, primarily in Louisiana, according to the Deepwater Horizon Joint Incident Command. 

BP America Chairman and President Lamar McKay said Sunday; “BP remains committed to remedying the harm that the spill caused to the Gulf of Mexico, the Gulf Coast environment, and to the livelihoods of the people across the region.” 

BP Shrugs Responsibility For Explosion

In remarks Wednesday after the release of a BP-led investigation into the cause of the Deepwater Horizon explosion in April, BP’s incoming chief executive Bob Dudley said, “the explosion on the Deepwater Horizon was a shared responsibility among many entities.”

These claims come in harsh opposition to BP America Chairman and President Lamar McKay’s earlier statements - “Liability, blame, fault, put it over here … we are the responsible party.”

According to the investigation - which BP funded, led, and published - the ultimate explosion of the Deepwater Horizon rig was the result of a chain of blunders - eight incidents in all. 

First, the cement barrier meant to isolate oil from the annulus (the space between the casing pipe and the surrounding rock) failed to isolate the oil. Then, another measure - called “shoe track barriers” - failed to isolate the oil. 

Negative-pressure testing was somehow accepted, and crews failed to recognize the influx of oil into the wellbore. Safety mechanisms should have then closed the blowout preventer, but instead the oil-mud mixture was diverted into the mud-gas separator, where the gas was vented directly onto the rig. Although a safety mechanism was designed to then prevent ignition, the fire and gas system failed.

All in all, the blowout preventer was ineffective although three separate methods of launching emergency mode were initiated.

Pressure Tests Determine Oil In Annulus; Officials Debate How To Proceed

by Miles Wolf Tamboli - Talk Radio News Service

In a conference call with reporters, Friday, National Incident Commander Thad Allen reported the status of pressure tests on the Macondo deepwater well - the well responsible for the months-long oil spill in the Gulf of Mexico - which resumed Thursday after storms passed through the Gulf.

Allen told reporters that the tests had revealed, “something that is between the annulus and the reservoir that is not allowing the flow of hydrocarbons … the question is, what to do about that moving forward.” 

Crews have determined that there may be as much as 1,000 barrels of “stagnant” oil suspended in the well, which could compromise the success of the bottom kill. “Tt remains a work in progress,” said Allen; “we’re trying to assess the options that we have. Everyone is in agreement that we need to proceed with the relief well - the question is how to do that.”

There is a risk that pumping mud and cement into the bottom of the well could increase the pressure beyond the threshold of the machinery now holding the well shut. “To increase the pressure in the blowout preventer and the capping stack in excess of 7,500 PSI would put that link in between them at risk, and we’re trying to figure out what that means and how we could mitigate that risk,” said Allen. 

Officials report that they are still wholly committed to completing the relief well and executing the bottom kill, and Allen reported that despite pressure test results showing a possible situation in which conducting a bottom kill could endanger the well’s integrity, BP officials would be “delighted” to show that they could, “drill down over 17,00 feet below sea level and hit a 7-inch pipe.” 

“The relief well will be finished, and that is the end result. How it gets finished will be determined on risk mitigation and the way forward that’s being discussed right now. The relief well will be finished - we will kill the well,” Allen concluded. The well will take about 96 hours to complete once drilling has resumed, according to administration officials.

Relief Well Drilling Suspended Due To Weather

By Miles Wolf Tamboli - Talk Radio News Service

As heavy storms brew in the Gulf of Mexico, National Incident Commander Admiral Thad Allen reports that drilling will halt on the relief well that may finally put an end to the months-long BP-Deepwater Horizon oil spill until the weather system has passed.

The Development Driller III, which has drilled to within about thirty feet of the crippled Macondo well, will disengage from the well itself but will remain onsite through the storm. Allen told reporters that the joint command had expected to complete the relief well on Thursday or Friday of this week - “this could potentially delay the final portion of the relief well for two to three days.”

The response team does not expect the storms to reach hurricane status, but are executing safety measures “as a precaution.”

In the meantime, the team, “will continue our aggressive search for oil that’s onshore in the marshes, to make sure we’re being responsive to the oil that does appear.”

“As we near the completion of the relief well, we’ll kind of assess where we’re at because we are moving into a new phase, where we’ll be focusing on locating any oil that remains out there - surface or subsurface - focusing on cleanup, and starting with the long-term recovery issues, and making sure that BP maintains their commitment,” said Allen.

Final Well Kill May Begin This Week

by Miles Wolf Tamboli - Talk Radio News Service

In his daily operational update Monday, National Incident Commander Admiral Thad Allen told reporters that “the job before us now is to finish the relief well… and then seal the well with cement from the bottom up. That will, in our view, at that point, permanently kill the well.”

“We expect that some time towards the end of the week we’ll be in a position to intercept the annulus and commence the kill,” he said.

In the meantime, the response team is moving forward, focusing their attention on cleaning the beaches and wetlands impacted by the Deepwater Horizon oil spill.

Over the next week, Allen will be meeting with local leaders and parish presidents along the coast to coordinate a stronger local response.
