It’s as if Deepwater Never Happened..

cairn-energyWhen the Deepwater disaster occurred in the Gulf of Mexico four months ago, many commentators argued that this was a “game changer” that would change the energy debate forever.

Politicians and the public would realise that the ecological and social cost of offshore drilling was becoming unacceptable, the thinking went.

If you morph the lessons of the Deepwater disaster as well as the Exxon Valdez, it is that the risks of deepwater drilling are huge. Everyone though realises that we were lucky in the Gulf, where the warm waters are more able to breakdown the oil compared to the cold waters of the Arctic.

In the the Arctic some 5 million barrels of oil spilt would have been a complete ecological catastrophe as the oil would take years – decades even – to break down.

But the lessons of Deepwater has not been learnt. The oil industry is just carrying on regardless.  Going ever deeper, going ever further into the Arctic.

Take this week’s news about Cairn Energy that says it has found natural gas off Greenland’s western coast.

In the words of respected energy correspondent , Guy Chazan, from the Wall Street Journal, the find is “bolstering hopes that the area could become one of the world’s last significant untapped hydrocarbon provinces.”

Although the find is currently too small to be commercially viable, Chief Executive Bill Gammell said he was pleased with the results. “We’re encouraged because we’ve established there are hydrocarbons in a basin that nobody has ever drilled before that’s the size of the North Sea.”

A new North Sea in the Arctic.

As Guy Chazan argues: “Some of the world’s largest energy companies have gravitated to Greenland’s iceberg-strewn waters in recent years, lured by estimates of its enormous resource potential. The U.S. Geological Survey says the area could hold around 50 billion barrels of oil and gas, more than the total proven reserves of Libya.”

But after Deepwater, when we have witnessed what can go badly wrong when the industry pushes the boundaries of new frontiers, should the industry be there at all?

A Greenpeace protest ship has arrived in the area to protest against Cairn’s, but a Danish warship prevented the protest vessel from entering an exclusion zone around the rig.

Greenpeace argues that “companies like Cairn Energy who chase the last drops of oil at any environmental cost are pushing us in the wrong direction. It’s time to go beyond oil.”

The commentators said Deepwater was a game changer, but the game hasn’t changed at all.

Its as if Deepwater never happened. Because the game is still all about oil..

BP’s Deepwater Horizon – BP Begins “Fishing Operation” – and Open Thread

Based on a press release by BP this evening, BP started the “fishing” operation aimed at removing the drill pipe this is within the BOP this morning.

One reason for removing the drill pipe is a practical one, according to a technical talk by BP’s Kent Wells on August 19:

Reporter: I was hoping you could explain a little bit more why you need to remove the drill pipe; how it would impede the progress in moving the capping stack and the legacy BOP and putting the new one on.

Kent Wells: Yes. Another good question. So, we could have up to, I think it’s around 3,500 feet of drill pipe hanging below the BOP. And, if we were to – and we believe that the drill pipe’s being held by the BOP. So, if we were to try to pick up the BOP right now, we’d have to lift it 3,500 feet straight up to pull all of the drill pipe out, and then we’d have difficulty handling that, et cetera.

So, we think it’s more prudent for us to go in and try to what we call fish it, actually pull the drill pipe out first and recover all of it, and then go and then take off the capping stack and then recover the BOP. So, I think that’s the procedure that we believe is the most prudent way to go about it, at this point in time.

In the same technical talk, Kent Wells indicated that the fishing operation wouldn’t be very easy to watch through the ROV cameras:

We’ll actually be fishing inside the capping stack down into the BOP, so there wouldn’t be any good ROV feed that would indicate that. But, what we will do is we’ll make sure that we keep you informed through briefings or releases, et cetera, about how that process is going, so that you understand it.

Once the drill pipe is removed, the next step will be to remove the blowout preventer (BOP) in an undamaged way, so that it can be used as evidence in determining why it did not function properly at the time of the original blowout. Admiral Allen sent Bob Dudley a letter, giving him until Sunday evening to put together a plan for safely removing the BOP, and ensuring that the BOP salvage operation does not compromise the investigation. According to the letter:

According to BP’s recent press release, once BP gets approval, it will proceed with an operation in which it replaces the original BOP with the BOP from the second relief well. In anticipation of a successful operation, BP has unlatched its BOP from the second relief well site.

BP’s press release also indicates that BP and the federal science team are also making contingency plans, in case something goes wrong with the fishing operations.
