Top Hat #8

After 7 attempts at an oil cap to contain the crippling gush of oil;  the 8th containment cap may be the prodigal son. Watch a visual confirmation here:     http://www.ustream.tv/pbsnewshour

Currently, the pressure reads at 6745 psi  and has been climbing approx 2 psi/hour.  A disheartening number for the residents of the Gulf Coast who were hoping that the psi’s were in the 9000 range.

Normally, this low pressure would denote that the well board is compromised and oil will need to be released onto the 4 production vessels which was said by Coast Guard Admiral Thaad Allen to “have the capacity to hold 60-80k bpd”.

However, the general consensus seems to be leaning towards the belief the well has low levels of oil because it has been gushing for so long as opposed to stating that there is another, unfounded, leak.

It was felt that the continuation of testing should continue because the majority of the other factors were positive.

During the integrity testing , all the valves are closed which allows the oil to be fully captured.

The Gulf Coast residents can sleep easier tonight knowing that the testing will continue for at least another 24 hours

At this point in the game, any break from the oil is happily received.

Relief Well Progression

After a little over 24 hours of the subsiding of the drilling of the relief wells for the well integrity test, DD3 and DD2 have been put back into production.

As of this morning, the Relief Wells are nearing the end of the precision phase of the relief effort, using magnetic ranging to give direction to assist steering the drill bit towards the blowout well bore and have drilled within 14.8 feet laterally from the well with an angle of 1.9 degrees.

So close, yet so far away for us Gulf Coast residents who are waiting for the intersection with bated breath.

Once the ranging is completed, the next step for the Relief Well will involve the drilling of 24 ft to the casing point which is hoping to be completed, by the middle to end of next week (July 21-July 25, 2010).

The final drilling intercept to kill the well will be the last week of July, a positive jump from the initial completion date of mid-August.

A friendly note to my local friends~ Enjoy your rest tonight. You’ll need your strength for the next coming days.

The containment chamber that was being fabricated to hold the released oil in the Gulf of Mexico needs to fall back on Plan B as the containment dome encountered flammable hydrate formations as it was lowered onto the leak site.

The mixture of oil, natural gas, pressure and cold water has contributed to the formation of gas hydrates, similar to ice crystals, which formed on the inside of the 100-ton chamber as it neared the seabed and plugged up the top of the structure from where the oil was to be funneled to a vessel on the surface stated BP chief operating officer, Doug Suttles.

BP officials were not giving up hopes that a containment boxes could cover the well. But they said it could be Monday (05.10.2010) or later before they decide whether to make another attempt to capture the oil and funnel it to a tanker at the surface.

Meanwhile, a Plan B has been incorporated which includes crews who are planning to park the giant oil-containment box on the bottom of the Gulf of Mexico, and offload equipment that could be used in a new attempt to stem the flow of oil gushing into the sea.

The company was considering several options, including the most promising technique of lowering a smaller containment box to control the oil flow known as a “top hat” which could be implemented around the middle of this week.

Another option, alebit extended project is to utilize a tube to shoot mud and concrete directly into the well’s blowout preventer which would then be sealed by cement, a process called the “junk shot” that could take two to three weeks.

Other options under consideration included raising the box high enough that warmer water would prevent the slush from forming, or using methanol gas to prevent the crystals from forming.

Philip Johnson, a petroleum engineering professor at the University of Alabama, comments on a risky but possibly effective option of cutting the riser pipe and slipping a larger pipe over the cut end could conceivably divert the flow of oil to the surface.

“That’s a very tempting option,” he said. “The risk is when you cut the pipe, the flow is going to increase. … That’s a scary option, but there’s still a reasonable chance they could pull this off.”

Meanwhile, The Joint Response Team continues to use boom, skimming, controlled burns, and chemical dispersants to prevent the oil from reaching Gulf coastline.
