The deepest research bore hole ever drilled was in Russia, on the Kola peninsula. Over a period of more than a decade a huge purpose-built rig drilled
to over 12 kilometers to investigate the structure of the Continental Crust (sorry about the units, I'm in Australia and we're metric here - so are
The results showed unexpected fractures and fissures and water-bearing zones deep in the crust, where conventional wisdom expected the pressure of
rock above to close up all cracks.
The deepest oil wells that I know are drilled to about 6km, say 20,000ft. Most normal oil wells are drilled to about 3000 to 5000 meters -10,000 to
16,000 ft. etc.....
Well where to begin,
How about Joe Vialls is a interesting individual if he is at all. I believe it must be a group as opposed to an individual. At any rate that was one
well and it took the Russians 10 years to drill it. In other words their technology sucks but they are persistent and overly concerned with records as
opposed to results. Sort of like adolescent bragging rights.
And the well never showed any oil production.
Now this is crap and I am the living proof of that.
Around a month after Hurricane Allen destroyed my home in Corpus Christi I found myself on a Jay Storm jack up rig, #13, about 20 miles off the coast
of the Mansfield Cut pre paring to finish up a well. The true vertical depth [TVD] of this well was 29,000+ feet with a bottom hole circulating
[BHCT]temperature of 365+ degrees and we used 22#/gal cement slurry to secure the casing in the well bore. And it only took about 6 months to drill it
as opposed to 10 years and it tested at 50 million cf of gas a day and I can't remember the amount of condensate. Heck, it was 24 years ago
In short there are parts of Joe's tale that are not even close to ringing the 'bell of truth'
There are wells in certain parts of the world that have been depleted and mysteriously replenished
The Gulf of Mexico is one of these locales.
Whether the recharging is due to migration from another zone or recreation from the core is the subject of an International Symposium somewhere around
now. I will spend some time searching for it but it is late here and I am tired. I will look for awhile though
Found mention of it, here you go
The debate about cooking up hydrocarbons keeps getting hotter.
Some scientists insist that all petroleum comes from abiogenic processes, with hydrocarbon development occurring in the Earth's mantle.
Most geochemists and petroleum geologists remain convinced that crude oil and natural gas have organic origins.
Look for this dispute to intensify in 2003, with new heat coming from an unexpected venue. In June, AAPG's typically sleepy Hedberg Conference could
be the spark that sets off scientific fireworks.
Hedberg conferences address topics proposed by AAPG's Research Committee. They take place in informal settings, with attendance limited to 80-100
On June 9-12, however, a Hedberg Conference will be held in London with the theme "Origin of Petroleum -- Biogenic and/or Abiogenic and Its
Significance in Hydrocarbon Exploration and Production."
"The timing is right," said Barry Katz, a ChevronTexaco Fellow in Houston and a member of the conference's program committee. "Historically, what
has been the big issue is that there's essentially a Western and an Eastern school of thought.
"On the Western side, we've gone through what you've typically done in the scientific method," he noted. "The Russian arguments have been just
that, arguments. We have yet to get them in a room to see what they have on the table."
Katz said he hopes the leading theorists from both sides will attend, so "we can have a balanced view and get everybody to talk to each other.
That's what the Hedberg conferences are all aboutwww.aapg.org...
That's all Folks, Goodnight,
