BP is sort of off the hook for most of what comes next....They did their work, cleared out the bad stuff and are about to reopen a dangerous pressure area, which should prove just how stupid these people are...or they will discover they can seal this well temporarily and make big bucks using the oil and gas waiting there patiently and quietly rob America, again! Why cap an easy oil collection point? I do not even see the rationale, but do see some dangers if the pressures are different at the side of the well they tap... They could redo the damage they just eliminated....Hubris. As for the clean up, the oil is in the current, is slowing some progress because the oil must be converted to other chemicals to reduce its plume size and eliminate continued damage to wildlife deep in the Ocean/Gulf currents. The benefit would be more Phytoplankton, but it won't happen using Corexit as a dispersant. Petrotech 25 will work in very cold areas, and the real problem is getting it to the points of concentration. Does BP have the intelligence to use it? No sure, but if not, these continued storm surges will effectively cough up a lot of denatured oil leavings, and corexit remnant tar balls and matts of oil sludge. Hopefully the States will hold BP responsible, but they will have to document their efforts and get Leaders to force the issues!
Best of luck, Gulf states! Someday we might come and see what's left over from all the damage and heat of summer dead zones....

Seems like they must be listening to me....Then again, they might have just decided that the kill would be safe and gone that direction, which, personally doesn't sound feasible or intelligent in any manner, since the pressures are too high to secure a certain seal, and the oil and natural gas is there already at high enough pressures to last about 20 years or more...That's a good well, snookie, woookies! (Baby talking it to be calm....) Otherwise the mud will not be adequate to prevent another vent from opening in the future...with the same effect as the first errors made....(You know, I think I WILL take door number 2...Let's produce some oil!)

I think your on to something Greg. That may very well be the plan. Salvage the well. ? is, how tight is this cap? I speculated that what they may be doing was use a Relief well, as the main bore, releasing pressure on the origional bore, then close it off. Looks like they're halting the Relief wells so they don't get a side blowout, or possible, they've run into problems with the Relief wells.

Listening to reports on Fishermen, and Sea Food suppliers in Northern Gulf, they seem to be under the impression that they'll be back to work in a few days? What's up with that?

This is a small update on world pollution and global warming. Noteworthy is that India has a concentration (as well as China) of underground coal fires ongoing, which are HUGE polluters. They are mostly started by lightning and go on for hundreds of years. Interesting update below.

Indian Ocean sea level rise threatens coastal areas

BOULDER--Indian Ocean sea levels are rising unevenly and threatening residents in some densely populated coastal areas and islands, a new study concludes. The study, led by scientists at the University of Colorado at Boulder (CU) and the National Center for Atmospheric Research (NCAR), finds that the sea level rise is at least partly a result of climate change.

Sea level rise is particularly high along the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra and Java, the authors found.
The rise-which may aggravate monsoon flooding in Bangladesh and India-could have future impacts on both regional and global climate.

The key player in the process is the Indo-Pacific warm pool, an enormous, bathtub-shaped area spanning a region of the tropical oceans from the east coast of Africa to the International Date Line in the Pacific. The warm pool has heated by about 1 degree Fahrenheit, or 0.5 degrees Celsius, in the past 50 years, primarily because of human-generated emissions in greenhouses gases.

"Our results from this study imply that if future anthropogenic warming effects in the Indo-Pacific warm pool dominate natural variability, mid-ocean islands such as the Mascarenhas Archipelago, coasts of Indonesia, Sumatra, and the north Indian Ocean may experience significantly more sea level rise than the global average," says lead author Weiqing Han of CU's atmospheric and oceanic sciences department.

While a number of areas in the Indian Ocean region are experiencing sea level rise, sea level is lowering in other areas. The study indicated that the Seychelles Islands and Zanzibar off Tanzania's coast show the largest sea level drop.

"Global sea level patterns are not geographically uniform," says NCAR scientist Gerald Meehl, a co-author. "Sea level rise in some areas correlates with sea level fall in other areas."

The new study was published this week in Nature Geoscience. Funding came from the National Science Foundation, NCAR's sponsor, as well as the Department of Energy (DOE) and NASA.

-----Wind and sea level-----

The patterns of sea level change are driven by the combined enhancement of two primary atmospheric wind patterns known as the Hadley circulation and the Walker circulation. The Hadley circulation in the Indian Ocean is dominated by air currents rising above strongly heated tropical waters near the equator and flowing poleward at upper levels, then sinking to the ocean in the subtropics and causing surface air to flow back toward the equator.

The Indian Ocean's Walker circulation causes air to rise and flow westward at upper levels, sink to the surface and then flow eastward back toward the Indo-Pacific warm pool.

"The combined enhancement of the Hadley and Walker circulation forms a distinct surface wind pattern that drives specific sea level patterns,"
Han says.

In the Nature Geoscience article, the authors write, "Our new results show that human-caused changes of atmospheric and oceanic circulation over the Indian Ocean region-which have not been studied previously-are the major cause for the regional variability of sea level change."

The new study indicates that in order to anticipate global sea level change, researchers also need to know the specifics of regional sea level changes.

"It is important for us to understand the regional changes of the sea level, which will have effects on coastal and island regions," says NCAR scientist Aixue Hu.

The research team used several sophisticated ocean and climate models for the study, including the Parallel Ocean Program-the ocean component of the widely used Community Climate System Model, which is supported by NCAR and DOE. In addition, the team used a wind driven, linear ocean model for the study.

The complex circulation patterns in the Indian Ocean may also affect precipitation by forcing even more atmospheric air than normal down to the surface in Indian Ocean subtropical regions, Han speculates.

"This may favor a weakening of atmospheric convection in subtropics, which may increase rainfall in the eastern tropical regions of the Indian Ocean and drought in the western equatorial Indian Ocean region, including east Africa," Han says.

I Think they saw that the long-term pressures were possibly workable and have been discussing the production potential instead of the closure issues..Well pressures are aroung 10,000 psi, not much higher...By slowing the completion of the relief wells they reduce the potential of a pressure release from the relief well which could happen if the layer they are drilling is at all permeable. I believe they are going to come up with a surprise announcement that the well is going into production with no loss of oil if they do. The extra lines they connected are to deal with the gas issues, and the upper levels will need to be adapted to allow all gases to be produced and not burned away, as has been done and is being done. A permanent solution might just be a full-scale pipeline from the well to the shore with a link to a local refinery. If that occurs, they will not kill the well...but produce it...And that is actually a better result if it can be done safely....That is, what they are discussing...in my opinion...

They probably just woke up and recognized that - - if they shut all valves - - such high pressures (as quoted by experts) of 100,000 psi would probably blow the new well cap off in a split second.
However, just closing some valves, and having a collection tube attached and directing the oil up (and into a tanker) might work.
But what would they do with the tremendous amounts of poisonous gases (benzene, H2S, CH2Cl2) that come along with the oil? Lowering the temperature would liquefy benzene and dichloromethane (methylene chloride), but to separate out H2S they'd have to go to lower temperatures and possibly higher pressures.

After days of progress, BP freezes work in Gulf

"The oil giant and the government said more analysis was needed before testing could proceed on a new temporary well cap — the best hope since April of stopping the geyser. Work on a permanent fix, relief wells that will plug the spill from below with mud and cement, also was halted."
