At bottomhole conditions the "methane" natural gas is in solution and not crystalline. It's just like the CO2 in your Miller Lite, it does not come out of solution until the pressure is reduced to the "bubble point" pressure. Even if the reservoir is at the bubble point if the gas breaks out of solution 1 standard cubic foot of gas at the surface with be compressed to a volume of .00155 cubic feet down hole @ 10,000 psi pressure.
Hoagland, like Matt simmons,Mikao Kaku, Bill Nye and others continually demonstrate their ignorance about the subject matter. Of particular interest was the mindless comment about 100,000 psi bottomhole pressure. If that was the case and they drilled into a permeable formation it would have launched the entire rig into space immediately upon drilling into it. The earth itself only weighs about 164 #/cubic foot if it was solid silica, so at 18,000' with 100,000 psi of pressure the force lifting the earth would be 14,400,000 pounds per square foot with the weight of the earth only being 2,952,000 pounds per square foot. If Hoagland was right we would be looking at oil volcanoes in the gulf without any drilling. BP reported 14#/gallon rat hole mud in the hole before cementing. Therefore this was the mud weight that balanced the reservoir pressure so that they could run casing before the blowout. This mud has a hydrostatic gradient of .728 psi/foot of depth. The reservoir pressure is therefore at most 13,099 psi.
If the casing has split and it's pressuring up outside the wellbore it certainly isn't good, but it's still nothing that the relief wells can't handle with the bottom kill. It is simply a matter of balancing the heigth of hydrostatic head with the weight of mud to match the bottomhole pressure. This is your high school algebra teachers moment. If 18,000 heigth of 14#/gallon mud equals 13,099 psi and the casing is split at 1000' from the surface what weight of mud must be pumped to equal 13,099 psi.

Read my post again.
How do you use a GPS device and a Depth Finder to map a gas bubble on the ocean floor?
That is the basis of the whole thing. I don't think an average High School Student would take more than a minute to cut through that.
Could be he is that illiterate, but do you really think so?
Gulf of Mexico Framework Bathymetry Data Service Award number IA560110408b, Category 2: Establishing Framework Data Service NOAA and ESRI will establish an OGC compliant Web Feature Service of framework bathymetry data for the Gulf of Mexico.
Bathymetry provides the spatial infrastructure for a broad range of gulf-wide users including those in recreational boating, fishing, ecosystem modeling, flood inundation, marine transportation, oil and gas exploration and management, dredge material management, and coastal hazards.
User demand and expectation for available bathymetry has increased as the terrestrial geospatial community has progressed and users see the value of seamless map products for the land-sea interface.

It never ceases to amaze me that when a complex subject is at hand, wannabe experts crawl out from under every adjacent rock and start screaming. In medicine, we see this with all sorts of semi-schooled people who for one reason or another want to be or appear to be doctors and AREN'T: angry nurse practitioners, grandiose nurses who have become confused about what they don't know, PAs, non medical PhDs of all stripes, naturapaths, chirosociopaths and other myriad sub-criminal sociopaths, narcissists and opportunists. During the swine flu scare, all of these types crawled out and either tried to sell their uneducated opinions or actually sell some type of snake oil. It resulted in mass confusion.
Here we see the same damn thing; all sorts of people with no credentials in petroleum chemistry, geology, rig engineering, etc., running their uninformed mouths, in order to gain their moment of fame.
Too bad we no longer have actual news and independent reports whose reports could be trusted. We are surely in the age of confusion. Information age----BS.
