Y'all have probably dealt with this somewhere, but I understand that there is supposedly a huge amount of oil below the Haynsville Shale Gas find.  It is real deep, but is anyone anywhere looking at trying to exploit this?

Nathaniel, this rumor pops up from time to time. It seems to be a favorite comment of certain industry field personnel when quizzed by laymen. No one has ever posted anything to substantiate such a speculative statement. In fact with the rare exception of specific geologic conditions, oil can not exist at extreme depths. Try Googling, "oil window" for a comprehensive explanation of the depths at which oil occurs.
Just how deep was the b.p well in the gulf that blew out . Wasn`t it realy deep?
The exceptions in the Oil Window theory are formations under the oceans and below massive salt formations. Both tend to make the pressure and heat less than in similar depth formations on land or formations not over laid by salt. The scientific concept is called thermal maturity and is abbreviated Ro. Thermal maturity is a measure of depth, heat and time. The more thermally mature a hydrocarbon the less likely it will be liquid. The gas produced from the Haynesville Shale is highly thermally mature meaning it is dry and contains no liquid components. For that reason, it requires very little treatment to meet pipeline requirements. IANAG.
You can Google Thermal Maturity or Ro but it's hard to find a brief and simple definition. This comes pretty close to condensing the concept for posting on GHS.

Thermal maturity
The amount of heat, in relative terms, to which a rock has been subjected. A thermally immature rock has not been subjected to enough heat to begin the process of converting kerogen to oil and/or gas. A thermally overmature rock has been subjected to enough heat to convert it to graphite. These are the two extremes, and there are many intermediate stages of thermal maturity.
While we tend to say an area is "too deep" for oil to exist, it's not really depth, it's temperature and pressure.

Rock is cooler under the ocean. Rock is also cooler or hotter under dry land or under the sea depending on what kind of rock is above and below the layer you're interested in. If the deeper rock doesn't conduct heat well, and the shallower rock conducts heat well, it will be cooler. Switch the rock around and the rock at the depth you're looking at will be hotter. The amount of heat coming up from deep underground varies from place to place as well.

For any one particular area, as you go deeper, you will usually reach a depth where it gets "too hot." The "too hot" depth will vary from location to location.

Also, for the BP well, when they say it's 15000 feet deep, you have to subtract 5000 feet because that's where the sea bottom is. The rock is around 32F at the sea floor and starts heating up as you go down from there.
The consensus here and among the traditional experts seems to be that it's not true and that it's impossible due to the temperature and other conditions at that depth the local area.

Of course, the experts are sometimes wrong, and maybe someone will drill some wells, produce the oil and prove them wrong. I wouldn't start spending the money yet, though.
wow this is one persistent rumor, i think i've seen it 4 times now
Jack Blake said it is very light gas condensate. Mrs Jane said it is at about 18000' to 20,000'. It's all over the place under the HS.
CONDENSATE UNDER THE HS CRIED JACK BLAKE
Olddog says jack blake must be spending some of his time in the barber shop or the Greasy Spoons in Pleasant Hill and must be listening in to the consultants conversations with info like that. Olddog has heard rumors in this fashion but Olddog has decided to just enjoy the dry gas mailbox money that's a coming. Keep howling Jack Blake.
Keep enjoying that mailbox money howled Jack Blake!
Why do they waste their money to drill exploratory wells down deep if there isn't anything down there or couldn't exist?
What deep exploratory well are you talking about?
