Off to the Corporate wars for a few days. Check in if I get the chance but should be back by the weekend anyway.

Gotta go show'm how smart I am. Maybe I'll just goof up on purpose and let them sever me to the tune of 18 months salary and full retirement.

Have fun!

Have fun?

Now you're talkin, stick it to The Man!

tell them tio use their oil in an enema.....
fight the power....

or simply invite bear to come along and give a talk on your behalf.....

Why does that remind me of basting a turkey?

Oh, yeah. I have a date with a dead bird next Thursday.

Me too

Hey! If it wasn't fun, I wouldn't be doing it. The day the fun stops, I'm outta there.


Fantastic Forum! Width and breadth of people like I haven't seen in 35 years in this industry. And all pointed towards accomplishing one goal.
And we do it again in 18 months.

oil men meet and have unified goal! must be a conspiracy.....like the masonic society of black gold......
ok, which brands of whisky got sacrificed over the servings of sacrificied cow.... cough up.....

I will have to admit, it was very much a 'good time was had by all.' Like the good times in which we live today. But I define those good times differently from the man on the street. My good time is when none of my group will be hunting a job next spring because of the annual rounds of layoffs. Instead we will be getting retainment bonuses and good things said about us.

Our target for this forum was what we refer to as "Tight Gas" ie natural gas found in rocks that have a very low capacity to flow. If anyone is familiar with the term, the world definition is below 0.1 millidarcies permeability. Personally, I think 0.1 is free flowing. Where I work is <0.01.

I look at your post much like my cat stares at the TV screen.

Would you like some references or would you rather ignore my technical jargon?

Hehe that's all right, I could always look it up later.

sucker here....stepping up to the plate like an idiot but curiosity is something else....


so are you talking about how the gas permeates into the rock or between layers of rock?
if its in the rock and not chambers like the lens you get under the sea bed, then how is it stored in there and then extracted.....

First: Go to http://www.pmel.org/NaturalGas-Glossary.htm and look up
(in alphabetical order)
Btu
Formation
Logging
Mcf
Methane
Permeability
Porosity

Then try http://home.att.net/~numericana/answer/gas.htm to read about Hydraulic Permeability near the end of the page. From what you’ve said of yourself, up to here should be generally a breeze.

http://www.naturalgas.org/overview/background.asp will give you a lot of stuff at a higher level fly-over. http://www.akita-drilling.com/glossary_of_drilling_terms.htm and http://www.aga.org/Content/NavigationMenu/...lossary_(A).htm are good places to return to when hitting new words. Some where in here check out the term ‘dry gas’ as well as Darcy as a unit of flow (http://www.sizes.com/units/darcy.htm).


Rock (in my case sandstone) is laid down with very high porosity and permeability (think beach sand). Over time, it is compressed, cooked and generally suffers the near shades of hell if buried deep enough.
What I work on and what the symposium was about, was extracting NG from rock that still has some small part of that porosity and perm left. (In my field the average is <8% porosity & <10 uD perm.

If I haven't bored you to tears and you're still interested in more .......

zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

Sorry, you guys were talking about cars or something weren't you?

i'll be checking this out but dont go thinking i wont be keeping an eye out on ya with the global issues....



i'll be back.....


sometime later.....

there is something innocuous about th following description....

ok....im gleaning a lot here.....

i bet traps take experience to spot....the longer you been at it, the better you are in recognising the places where they can occur.....right?

the seperation tank....does it use cetrifugal forces?

oh and one more...the 3d seismic....is that like a 2d array positioned on the surface and sound injected, then the time reposnses recomposited to give the box view of underground?

Horizontal Drilling - A major boon to the industry. When a zone is only 5 m thick and you can expose 500 m by drilling sideways......
A young lady I converted over to the dark side a couple of years ago spent some of her earlier life in drilling. She was 'drilling engineer' in an Amoco field in the southern UK At any rate, she and her team drilled a >3 Km horizontal off the UK coast. The rig was on dry land.

I'll mix a couple of these together - Your version on 3d durvey is correct. Set geophones in a grid on the surface and move a set of vibrations either via explosions (dynamite) or engine driven 'earth shakers' across the grid capturing the reflected sound waves. Traps are found via the 2d and 3d seismic. Looking for a particular wavelet contained in the box.
Traps were originally chased by locating a surface anticline and assuming it continued below the surface. For years we used 2d seismic - a single line of geophones up to several miles long going cross country.
Also we could use other folks successes and failures by 'correlating' existing well logs to imply a trap between wells.

Gravity separation of water, oil and gas

gravity you say eh....how long would the process typically take? a week?

Happens real time: In my area it's just water and gas so as soon as it hits the tank, the water falls out and the gas heads out the top (actually sucked out by a compressor). The gas in situ carries 1-3 bbl water/Mcf (million cubic feet) according to formation temperature and pressure.

In the area where all three (oil, gas & water) are produced, the above takes place except that the oil joins the water in the bottom of the tank. This is where the gravity is a little slower. With a tank with a capacity of 100's of barrels, the oil is sucked off the top, the water drained out the bottom while gravity is still working in the middle.
