Allen: Gulf Relief Wells Must Go Forward

BP's blown-out oil well in the Gulf of Mexico is not yet plugged for good, and work on what's been touted as the permanent solution will need to continue, the federal government said Friday.

Retired Coast Guard Adm. Thad Allen, the government's point man for the spill response, said crews must move forward drilling the relief well even though officials were still evaluating the best way to finish it.

"The relief well will be finished," he said. "We will kill the well."

BP had thought the mud and cement pumped in from above the leak may have essentially killed the well. But the relief well will allow engineers to pump in mud and cement from below, which is intended to permanently seal the well.

Special Section: Disaster in the Gulf

Work on the wells was stopped this week because of bad weather.

The decision to resume work on the relief wells means a key milestone in the crisis that wreaked havoc on the Gulf Coast's economy and ecosystem remains days off. However, Allen has repeatedly insisted on an "overabundance of caution" when it comes to permanently plugging the well.

Officials had been testing the pressure beneath the cement plug currently in place. Steady pressure would indicate the presence of cement in the space between the inner piping and the outer casing, likely indicating a permanent seal.

But because pressure rose during the testing, the scientists concluded that space still needs to be plugged in.

It would have been difficult to say the "bottom kill" was unnecessary after promising it for weeks as the ultimate solution, said Eric Smith, associate director of the Tulane Energy Institute.

"That's been the mantra all along, that they wanted to do the bottom kill," he said.

Proceeding with the relief well makes sense, said Bob Bea, a petroleum engineering professor at the University of California, Berkeley, who is conducting his own investigation into the disaster.

Too little is known about how much cement might be inside the space between the inner piping and outer casing to be confident the well is permanently plugged, he said.

"Everything we know at this time says we need to continue the work with the relief wells," he said. "We don't know the details of how they plugged the well from the top. We don't know the volume of material they put in the well bore, and without that we can't tell how close to the bottom of the well they got."

Drilling of the first relief well began in early May. Since then, the drill has been guided some three miles from the surface and two miles beneath the sea floor to within 30 to 50 feet of the target. The drill is about as wide as a grapefruit, its target less than half the size of a dartboard.

It's unclear when the drilling could be finished. Officials had projected as early as Friday before the nasty weather forced the operation to a halt. Drilling that final stretch is a time-consuming and careful process as engineers work to make sure they don't miss.

Crews dig about 20 to 30 feet at a time, then run electric current through the relief well. The current creates a magnetic field in the pipe of the blown-out well, allowing engineers to calculate exactly where and how far they need to drill.

The flow of oil into the Gulf has been halted since July 15, when a temporary cap over the well was able to contain the spill. But officials have stressed for weeks that only a bottom kill will ensure the well is no longer a danger.

Before July 15, the oil leaked almost unimpeded for nearly three months and spewed some 206 million gallons of oil, according to the government's latest estimate. The crisis began on April 20, after an explosion on the BP PLC-leased Deepwater Horizon drilling rig that killed 11 workers. Officials don't yet know the cause of the explosion, or why machinery designed to prevent the unchecked flow of oil failed to work.

BP has already spent $6.1 billion responding to the spill.

This is an example of utter baloney.

When BP capped the well and pressure held, the obvious conclusion was that the blowout did NOT damage the inner or outer casing. At that time the correct thing to do would have been to extend a standpipe down from the surface, connect it to the cap, then start pumping oil out of the oil field and into tankers.

In short, put the well into production.

After a number of years when the oil field was exhausted then it would not make any difference if the well was plugged or not because the oil pressure would no longer be there.

But, why don''t they do this?

They don't do it for 2 reasons:

1) The Coast Guard is seeking revenge against BP. They know that once the well is solidly plugged that BP will have to start all over again to drill another well into the oil field. After all the oil is still down there. This is expensive to BP and just further punishment. Of course, it also creates more jobs for the area.

2) Both the government and the other oil companies do NOT want a large flood of crude oil from the well onto the oil market. If that happened it would depress prices, lower gasoline prices, and otherwise make things good for the consumer. But from the governments point of view it would reduce profits to the oil companies and thus the taxes that they pay, it would reduce gasoline tax revenue and reduce money flowing into government coffers. It would also make it more difficult for alternative energy ideas to develop since many of them would no longer make any economic sense.

This is the reality of oil politics.

The whole episode has convinced me to be really, really thankful that the intersection of the North American and Caribbean plates is south of the Gulf of Mexico.

'Cuz I don't think these oil wells - what with the inferences that horizontal fracturing is a possibility when sealing same - have shown any indication that they would maintain their integrity in the event of a shallow earthquake.
