Skip to comments.BP's Deepwater Oil Spill - the Testing Continues - and Open Thread
Posted on 07/17/2010 9:52:05 AM PDT by profgoose
At this morning's press briefing, Kent Wells of BP reported that pressures have now reached 6,745 psi, and are building at about 2 psi per hour. BP is estimating ultimate pressure will be around 6,800 psi. While this is not as high as originally expected, there are several reasonable explanations for this lower pressure reading, including the possibility that the well is now somewhat depleted, and therefore has lower pressure.
BP seems to be encouraged by the results. Mr. Wells said several times, "We are encouraged that we have integrity," and "We find no evidence of lack of integrity."

There, fixed it.
My best guess is that the cap was designed for the 9000 number and they're pretty happy with the true numbers.
He is sayong of course tht the wellisn’t leaking, not that there is any interity, either at BP or in Washington.
Something nobody is talking about...the fact that oil is spewing out of that well at 100,000 barrels a day. THAT’S A LOT OF OIL! What if the Gulf at 5,000 feet below sea level has enough oil to last us for another 200 years?

I'm strongly suspecting that the reason the pressures are less than expected is because the Macondo well has been in communication with and draining a small compartment, rather that the entire accumulation. This reservoir is most likely composed of turbidite sands. Turbidites reservoirs are often "amalgumated" sands. That is they are deposited by a series of turbidity flows over some period of time. The sands may make one big pile, but are still individual sands. The pre-drill estimate of 50-100 million bbls is no doubt based on seismic data, which does a fair job of indicating the overall size of the sand accumulation. However, seismic is often too blunt a tool to image the individual turbidite sands that make up the whole sand accumulation.
In a compartmentalized reservoir, individual sands aren't well connected to one another. A well draining one sand may get little or no contribution from adjancent sands. In the normal oil field development and production situation a compartmentalized reservoir is a bad thing. It means more wells (hence more cost) are required to produce the field. In the present situation, compartmentalization may be a good thing. It means the last 80+ days of "production" may have drawn down the pressure in the compartment significantly from what was observed when the well was initially drilled.
You're leaving out the people who were talking about 70,000 psi. Good idea to leave them out.
That is a distinct possibility and sedimentary deposits may have combined to scew the original estimate.
Still.... that was a huge a variance but, Thank God Obama and his experts stopped the leak... for now.
An exercise in pronoun selection.
Is Obama Claiming Credit for Gulf Spill Solution?
THE PRESIDENT: Good morning, everybody. I wanted to give everyone a quick update on the situation in the Gulf. As we all know, a new cap was fitted over the BP oil well earlier this week. This larger more sophisticated cap was designed to give us greater control over the oil flow as we complete the relief wells that are necessary to stop the leak.
Now, our scientists and outside experts have met through the night and continue this morning to analyze the data from the well integrity test. What they’re working to determine is whether we can safely shut in the well using the new cap without creating new problems, including possibly countless new oil leaks in the sea floor.
Now BP’s scientists are the “Scientists formerly known as They”

Oooooh, you so clevah, Grasshoper.
Loved your double entendre(damn spell checker)
The GIF was my way of saying, “I’m ALL EARS, WHAT’S HAPPENING?”
I like it.
The 9000 psi figure was from wireline downhole measurements made before the blowout.
"My best guess is that the cap was designed for the 9000 number and they're pretty happy with the true numbers."
Design max pressure for the BOP stack was 13000 psi.
I can’t hear it because I need FP10. That will not install on my system. Will be looking at other sources that usually allow me to get audio/videos such as CSPAN.
Pressure readings after 41 hours were 6,745 pounds per square inch and rising slowly, Wells said, below the 7,500 psi that would have reassured scientists the well was not leaking. ...
What’s with the US and WE. BP you narcissist moron. You didn’t have anything to do with it you POS>
I fully expect after his little mini holiday is over we will hear about leaks from the seafloor. I hope that I’m wrong.
BELEAGUERED energy giant BP was hit with further bad news this morning as it emerged dangerous arsenic levels have been found in seawater around the Gulf of Mexico.
British scientists warned that the oil spill is increasing the level of arsenic in the ocean, and could further add to the devastating impact on the already sensitive environment.
BPs Deepwater Horizon rig has been spilling between 3,681,500 litres and 911,454,000 litres of oil into the sea per day since it exploded on April 22.
They said the arsenic then gets magnified up the food chain, as fish eat small amounts of the deadly poison and may eventually impact humans, researchers said.
Professor Mark Sephton said arsenic, which is found in seawater, was normally filtered out of the ocean when it combined with sediment on the sea floor.
But oil spills stop the normal process because the oil combines with sediment and it leads to an accumulation of arsenic in the water over time, he said.
Arsenic only needs to be a 10th of a part per billion to cause problems.
He added: Our study is a timely reminder that oil spills could create a toxic ticking time bomb, which could threaten the fabric of the marine ecosystem in the future.
What worries her most about the current spill are the unknown effects of the dispersant chemicals used to break up oil into small droplets that sink into the water column. “If they put dispersants into any body of water without the presence of oil, people would be up in arms about the release of such toxic substances,” she says. “But because they are being applied in the name of remediation, people stand by and say it’s OK. But it isn’t OK at all; it’s making the Gulf a big experiment with no baseline to judge the real consequences.”
Federal government biologists who approved the use of dispersants say the chemicals are the lesser of two evils: they are toxic to some extent, but they keep the oil from reaching sensitive wetland habitat along the coast. I ask Earle about this but, aside from the limited use of dispersants to protect specific marshes from approaching slicks, she will have none of it.
“Deploying dispersants at the well head and on the surface many miles from shore is shockingly irresponsible,” she says. “It means you are taking oil that could be collected on the surface and [causing] it to go where it is impossible to recover. Life in the water column is exposed to the chemicals from the surface... and it’s killing all the way.”
Plug the damn hole
On July 8, 2010, the Associated Press reported that U.S. Reps. Barney Frank and John Tierney stated publicly that Dr. Lubchenco should resign, and Frank said he intends to bring his request to the White House. Frank and Tierney represent New Bedford and Gloucester, Massachusetts respectively, New Englands biggest fishing ports. The two Democrats took the unusual step of calling for a senior appointee of a President of their own party to resign, saying shes failed their regions struggling fishermen.
That pressure reading can mean three things apparently. Reservoir depletion, Cross Talk with Another Reservoir, or Leakage into the porous rock strata. Going into the test that value was inconclusive and meant that Well Integrity was not assured. They are now going to just assume the well has been depleted and that explains the lower pressure. They have absolutely no way to prove that with any degree of certainty. So basically, we have learned nothing from this test and they continue to roll the bones (dice).
I’m a little concerned about your inability to express yourself. LoL
The scale and magnitude of this thing is being hidden from the sheeple.
Have they stopped the test yet ?
He’s such an as*. He really is. He’s such a freak. I KNEW he would try to take credit for it. So when it’s bad, it’s mean ole BP, evil oil, and so on, but some good news and he’s we, us and I. Gawd he makes me sick.
“Text version from The Oil Drum.”. Thanks. Like you commented a few posts down. Time to bring in the witch doctors with their bags of bones and trinkets. Maybe Obi from Nairobi has some he could give a call to be flown down to Houston.
BP leak puts up to 4.5 million barrels of oil in sea: IEA
Also, I don’t believe lots said on theoildrum. Most of them are peak oil, solar, windmill freaks. I think since the spill it’s changed as some sane people have signed up, but make no mistake, the libs are thick over there.
That is what they were before the BP spill, from what I gather. But since the spill lots of idle actual rig workers and even a few people from BP have been posting on the site.
Reports on the Oil Drum are that they were trying to collect some of that gas leaking from one of the Well Head Cement Ring Bleeder Lines down at the base. They were having difficulties. They need to find out what is leaking. That is the most important piece of information they can acquire over the next 24 hours. IMHO.
A truly educated take on the pressure drop. Thanks for posting and hopefully giving the “Doomsday Drama Queens” something to think about.
Probably because there is not much for the submersibles to do, other than a couple to monitor things. You don't keep expensive equipment like that "at depth" unless they are actively working.....too many things to go wrong.
Hey, joe. Guess what keeps the OIL from combining with the SEDIMENTS. Those nasty, evil old DISPERSANTS, that's what. The dispersants keep the oil in solution and suspension, and prevent such combination. So this looks like another place where the use of dispersants was A GOOD THING.
Agree. But they could have a few showing what they are doing at the seabed floor regarding the leak in one of the lower valves within the lower subsea floor casement. Then again, maybe they are doing nothing in that regards. The last statement was not meant as negative. Maybe they have to obtain a new valve or valve gasket etc., before any repair can be started.
You’re referring to the Muslim-in-Chief, right?
Skandi 1 has been parked down at the bottom of the BOP at the wellhead showing a closeup at the leaking Bleeder Line. They are playing a little trick with it however. The line they are showing is only the occasional leaker. The main leaker is the next one in the back and the angle they have obscures it. I think anyways. Skandi 2 has been showing the Three Ram Stack but not a clear image of the exit ports to determine if they stopped the test. There are 8 to 9 others online with feed.
