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.

BP’s Deepwater Oil Spill – The World Continues Drilling – and Open Thread

One of the questions I was asked earlier in the spill was, “Do you expect other countries to stop drilling in deepwater locations, because of the oil spill?” My response was, “Maybe a bit, in a few locations, but in general I expect the drilling to continue.” The world has so much equipment that uses oil as a fuel, and so little in the way of good substitutes, that it is really difficult for governments to decide to discontinue drilling. Furthermore, if an oil company has debt, it needs to continue drilling in order to repay its debt. Even if a company doesn’t have debt, stockholders expect dividends (often to make payments under pension plans), and this need to pay dividends contributes to the need to continue deepwater drilling. Even government-owned companies are under pressure to keep drilling, because governments often use their share of oil revenue to fund social programs.

Certainly there are theoretical reasons for not doing more deep-water drilling–concern about global warming, or fear of more oil spills. But the company that cuts back finds it difficult to support the amount of overhead it has with lower oil production, and the country that cuts back handicaps itself in terms of employment, tax revenue, and balance of payments. It is not a decision most countries are willing to take lightly.

When I look around the world, the only country (besides the US) that seems to have cutback on deepwater drilling is Norway. Norway banned the issuance of new deep-sea permits until the BP oil spill has been fully investigated. Drilling can continue in areas where deep-sea permits are already in place. This is a less severe cutback than in the US, since the US cutback applies to new drilling, including in areas where deep-sea permits are already in place. The Norway ban may have virtually no effect at all–this report indicates that the next licensing round is not until late 2011, and by that time the results of the US investigation will be known, so there may not be any actual impact of the supposed ban.

Elsewhere in Europe, there is generally no ban on deepwater drillng. The UK announced a announced a government inquiry into oil and gas drilling in the North Sea on July 17, but this is not a ban on drilling. European Union Energy Commissioner Günther Oettinger has voiced concerns about deepwater drilling, but so far, this has not led to action. Italy banned drilling within five miles of its coast and 12 miles from protected marine areas, but this ruling is expected to have little impact on the most promising deepwater oil areas, which are off western Sicily.

There are many areas around the world where deepwater drilling continues. The financial report for DryShips, Inc. makes the following statement regarding ultradeepwater drilling:

“It is important to note that although the US Gulf of Mexico is an important area for deep and ultra deepwater drilling it isn’t the only area for growth. West Africa and Brazil remain prolific in terms of discoveries and we are now seeing drilling in many new areas such as East Africa, Mediterranean Sea, Black Sea, Red Sea, India and the rest of the Asia-Pacific.

The Financial Times reports:

While the US quickly ordered a deepwater drilling moratorium, others, including Australia, Greenland, Norway, Canada, Libya, China, Brazil and Angola, have not followed suit.

Australia, which had suffered its own major blow-out and spill just months before the Deepwater Horizon accident, was unmoved.

Martin Ferguson, Australia’s resources minister, said: “Shutting down the industry and putting the nation’s energy security, jobs and the economy at risk does nothing [to ensure safe oil exploration].”

So at this point, the US seems to be mostly alone in its moratorium on deepwater drilling. And because of the many economic pressures, even in this country, there is likely to be continued pressure to rescind the moratorium as soon as possible.
