Why the Well in the Gulf cannot be stopped - What you didn't know about the pressure
I have not seen this information anywhere, and it just occurred to me today to compare something I saw several years ago to the well disaster in the Gulf.

Nobody can deny the pressure of the oil and gas coming out of the well is in the range of 20,000 to 50,000 psi. Due to the simple physics of the depth it must be a MINIMUM of about 20,000 psi.

In the late 1990's, I was at a defense department vendor meeting in Virginia and saw a device demonstrated that used water combined with a simple abrasive as a cutting device.

A stream of water 1mm or so in diameter was forced out of a super hard orifice at approximately 50,000 psi. I saw it cut 1" steel like it was butter. I also saw a video of the same technology adapted to a device to cut through 8 feet of concrete like it was not even there. In a few minutes it could cut a slab out of an aircraft runway so a fast repair could be made in situations where aircraft must land quickly.

Can you imagine the cutting power of an abrasive laden stream 8 inches in diameter at lets say 30,000psi or more?

The drill pipe in the Gulf well that extends down to the bottom of the well is as I understand approximately 8 inches in inside diameter with a 2" wall thickness. I realized today that with the pressure of the oil and gas coming out and with the sand and other abrasives that have to be carried along with it. That drill pipe is almost certainly already eroded away to practically nothing. It was never meant to withstand full flow at those pressures.

The reservoir of oil and gas at the other end of the pipe is estimated to be the size of Mt Everest. It WAS contained by thousands of feet of rock and the weight of the water in the Gulf. Those idiots drilled into something they were not prepared to deal with and it is going to kill all of us.

I think what they now know and are not telling is that it is not stoppable. The immense pressure is eating a hole in the floor of the ocean that will only get bigger and bigger. The pressure and the abrasive nature of the oil, gas, and rock particles that are coming up will eat a bigger and bigger hole until it literally does erupt like a volcano letting oil out and seawater into the heated area below and creating an explosion the likes of which has not been seen on this planet in hundreds of thousands of years.

There is no way anyone is going to survive this long term. The only game in town is going to be who can manage to be the last man standing.

Let us all hope that when the realization of this truth lands on the masses that they hunt down the greedy bastards who did it and make sure they die a long and torturous death.

Re: Why the Well in the Gulf cannot be stopped - What you didn't know about the pressure
To those who really want to know why the oil is shooting up from the drill pipe I'll keep it as simple as possible.

The well continues into the seafloor for 10,000 feet. The well pipe excludes the surrounding rock which is 2-3 times heavier per unit volume than the liquid and gases that are within the pipe. If the surrounding rock is a little more than twice as heavy as the material within the pipe, there will be an accumulation of approximately .5 psi per foot of depth. Therefore a well 10,000 feet into the seabed would generate a theoretical differential of 5000 psi if it were "shut in."

However, the well in question is not shut in, so the exit pressure is much less, but still great enough to generate the flows we see in the videos. When BP attempted the "mud kill" they were merely attempting to replace the lighter liquids in the drill pipe with heavy muds that equal the the density of the rock on the outside of the pipe which would balance the differential and stop the flow. This technique is used very often in oil and gas drilling procedures.

The well continues into the sea floor for 23,000 feet which is over and above the 5000 foot depth of the water.

Do the pressure calculation on that.


Anyway the density of the surrounding rock has nothing to do with the pressure of the oil and gas coming out of the well or the actual internal pressure of the well which many have estimated to be in the 50,000 psi range.

Plus add the pressure exerted by millions of tons of earth pressing on the oil pulled towards the center of the Earth by gravity. (uncalculable)

BOP below sea floor = 5067ft below sea level = ~18 360ft total vertical depth (TVD) feet.
(KB-(From kelly bushing-oil inductry term))

The mud weight used while drilling the pay zone(18360ft) was 16ppg

Hydrostatic pressure(HP) = TVD x 0.05 x Mud density(ppg)
=18 360 x 0.052 x 16
=15 275PSI HP

They displace riser with sea water ~8.5ppg

the hydrostatic pressure lost when they displace riser and 3000ft of wellbore (5067+3020=8087ft)
reduce HP=(8087 x 0.052 x 16)- (8087 x 0.052 x 8.50)
=6728 - 3574

15275 - 3154 PSI = 12 121PSI

so the Formation pressure = between 15275 to 12121PSI.

If that is the case, then why have even oil industry people admitted that the 15,000psi working pressure of the BOP was not sufficient to contain the pressure of the well?

My other question about the weight of the "mud" is how much overpressure did they have to use on it to force it down?

We will never be told the actual pressures they were dealing with, but they were obviously well beyond the capability of the BOP to contain them.

 Quoting: OsoSmooth



I'm an oil field engineer, I work with calculations like this on a frequent basis.

The average pressure in a formation is fundamentally related to the geologic overburden, a positive differential would lift the formation and find equilibrium.

At a seafloor depth of 18,000 feet the differential is around 9000 psi at the seafloor, considering the liquids within the pipe, if shut in. The depth of the water is irrelevant at the top of the BOP. If nothing but gas was inside the pipe from the bottom up, shut in pressure would be in the 20,000 psi range, but this is obviously not the case. Even if the well had a shut in pressure of 9000 psi at the seafloor, the oil and gas can not escape at 9000 psi due to friction within the the drill pipe. It's estimated that the exit pressure is less than 1000 psi.

That's why oil is blowing out the top of the BOP, the shearing ram didn't cut off the pipe and seal the flow, it has nothing to do with the pressure coming up the pipe.

15000psi working pressure doesnt matter as long as there is some mud in the hole. ~15275 is the "overpressure" or Hydrostatic pressure the drilled with, it would of blown out if the formation pressure was higher than this when they drilled through it.

roger, Im only going off the HP while drilling and reduced HP which caused the kick, so its really still a best guess. I still cant imagine it being higher than 20K PSI.

The compromised casing would mean that the formation pressure could be lower, not higher, right?

Directional data, drilling data and formation data are measured down-hole and transmitted to surface either as electromagnetic waves or pressure pulses where they are processed and displayed. Directional surveys are normally taken after each joint of pipe is drilled and while the next joint of pipe is loaded providing inclination and azimuth of the borehole.

Re: Why the Well in the Gulf cannot be stopped - What you didn't know about the pressure
Let us all hope that when the realization of this truth lands on the masses that they hunt down the greedy bastards who did it and make sure they die a long and torturous death.

Re: Why the Well in the Gulf cannot be stopped - What you didn't know about the pressure
The well continues into the sea floor for 23,000 feet which is over and above the 5000 foot depth of the water.

Do the pressure calculation on that.


Anyway the density of the surrounding rock has nothing to do with the pressure of the oil and gas coming out of the well or the actual internal pressure of the well which many have estimated to be in the 50,000 psi range.



I'm an oil field engineer, I work with calculations like this on a frequent basis.

The average pressure in a formation is fundamentally related to the geologic overburden, a positive differential would lift the formation and find equilibrium.

At a seafloor depth of 18,000 feet the differential is around 9000 psi at the seafloor, considering the liquids within the pipe, if shut in. The depth of the water is irrelevant at the top of the BOP. If nothing but gas was inside the pipe from the bottom up, shut in pressure would be in the 20,000 psi range, but this is obviously not the case. Even if the well had a shut in pressure of 9000 psi at the seafloor, the oil and gas can not escape at 9000 psi due to friction within the the drill pipe. It's estimated that the exit pressure is less than 1000 psi.

I respect your position based on you qualifications.

However, I beg to differ with you on the pressure. The lying cocksuckers aka BP said there is a oil/methane ratio of 60/40

If that well is indeed pushing out 40 percent gas, wouldn't that have a bearing on the psi?

Look at the methane formation as seen on this live cam:

I also have to believe the psi is MUCH greater than 1,000 psi. If I'm wrong, then I would have to believe the well pressure is low because a hell of alot of oil is gushing out elsewhere.

What do you think of that?

Re: Why the Well in the Gulf cannot be stopped - What you didn't know about the pressure
I have a few questions for those intelligent about this gusher. I don't know the answers.

1. Where is the Methane (40%?) reserve (pool?) in relation to the oil?

2. As I understand it the Methane is like slush, nearly frozen and under some pressure. If this stuff is being released wouldn't that create a void in the Methane reserve allowing the slush to warm turning into a more pressurized and volatlile gas? Does the oil reserve heat and expand creating increased pressures?

3. Does the temperature difference, if any, between the oil and Methane slush create a cause for concern?

4. Personally I can't see how 18,000 feet of sea floor could collapse but what is taking the place of the oil, methane, and other stuff venting from the BOP?

5. Is the sea floor bulging at the gusher site?

Thank you in advance for sharing your knowledge. :)

Re: Why the Well in the Gulf cannot be stopped - What you didn't know about the pressure
Ive worked on and designed several BOP containment devices. Spoke with people in the military, and several military contractors. I have since abandon that effort because of a shroud of secrecy.

At this point we the people of the world need to know something.

A) Are there more then one leaks
B) If so where they are
C) How were these leaks created
D) Who gave the order to use corexit.

From there we can make intelligent decision on how to possibly stop this or at least make some counter measures to contain and corral oil, and to possibly even set up massive movements for crop and farm cleaning is rain winds up being a problem.

As far as I can tell, two things can stop this. A) an explosive charge at 1 mile down, and b) a pole reversal.

so its not only the weight pressure , heat pressure from lava, , and these caverns are not just one big bubble they have a bit of infrastructure holding it all up too
