What I Didn’t Know About the “Oil Spill”


Apparently we have yet to learn the whole truth about the geyser of oil opened in the coastal waters off Louisiana. Basically this was a fumbled attempt by BP  to tap into an enormous high pressure, deeper than the permit, gas and oil pool, 125,000 sq miles in size. Maybe the largest on the planet.

Seleted quotes from Paul Noel’s at PESN: “Mother of all gushers could kill Earth’s oceans”.

The deposit is one I have known about since 1988. The deposit is very big. The central pressure in the deposit is 165 to 170 thousand PSI. It contains so much hydrocarbon that you simply cannot imagine it. In published reports, BP estimated a blow out could reach near 200,000 Barrels per day (165,000) They may have estimated a flow rate on a 5 foot pipe. The deposit is well able to surpass this.
...
Well, this time they hit a pocket of oil at such high pressure that it burst all of their safety valves all the way up to the drilling rig and then caused the rig to explode and sink. Take a moment to grasp the import of that. The pressure behind this oil is so high that it destroyed the maximum effort of human science to contain it.
...
The oil industry has knowledge of the deposit more than they admit. The deposit is 100 miles off shore. They are drilling into the edge of the deposit to leak it down gently to be able to produce from the deposit. The deposit is so large that while I have never heard exact numbers it was described to me to be either the largest or the second largest oil deposit ever found. It is mostly a natural gas deposit. That is another reason not to blast too willy nilly there. The natural gas that could be released is really way beyond the oil in quantity. It is like 10,000 times the oil in the deposit. By yesterday morning, the nature of the crude had changed, indicating that the spill was collapsing the rock structures. How much I cannot say. If it is collapsing the rock structures, the least that can be said is that the rock is fragmenting and blowing up the tube with the oil. With that going on you have a high pressure abrasive sand blaster working on the kinks in the pipe eroding it causing the very real risk of increasing the leaks.

More than that is the very real risk of causing the casing to become unstable and literally blowing it up the well bringing the hole to totally open condition. Another risk arises because according to reports the crew was cementing the exterior of the casing when this happens. As a result, the well, if this was not properly completed, could begin to blow outside the casing. Another possible scenario is a sea floor collapse. If that happens Katie bar the door.
