Help me out here, please.

I think I was hit on a little while ago, but I missed my chance by confusing her. :( :( :(


:wilted:

LOL too bad bor she is a pretty amazing women.


BTW can you tell me why dip angle, Gtotal <the total force of the magnetic field> and metal content of the soil doesn't affect my gyro tool and fucks my magnetometers?
Assuming +1 degree angle in the well bore?
PS ask Scots and he can help you

This is a car wreck of a thread here. Hey Dirty, did you ever get your money out of Roethlisberger?

That fucker owes me $50 still! :chomp:

Please define: "dip angle", "Gtotal" (why is the B-field "G", what does the grav const do here?), what kind of specific chemical content in the soil (para-, anti-, ferro magnetic chemicals will have different effects), "gyro tool", and "+1 degree angle in the well bore" (+1 degrees from orthogonal to the surface of the soil/earth?)

I don't know plug&chug engg stuff, I study the mathematics and theory. Real life applications belong to the engg's.


:cow:
 
Dip angle is the the angle of the geomagnetic field measured from the horizontal component of the field which points to true north.
b or gtotal are interchangeable, gtotal is an industry term. They measure the strength of the magnetic field in a given area.
Declination I assume you know.
Soil content varies, it is the ferrous we are concerned about here.
+1 degree angle from vertical, rig floor or platform down.
It is a trick question.
Gyros are only used, and there are many types for wells with an inclination. They present no value at vertical.
Magnetometers are all affected by the earth's magnetic field, strength, dip angle and ferrous content of the soil. As well as any metal we may have in the hole or from previous wells.
Gyros, are wether rate or laser-ring or mechanical are unaffected by the magnetics of the earth.
I can explain more later if you want. It is cool egg-head stuff. K when I get recharged for you just for asking. This is what pays my salary. Lots of other variables but again I can explain more later sleepy time now.
Check out www.scientificdrilling.com for some more info and study for your test.

Okay, this seriously bugs me. Leave it to the engg's to be too lazy to use a different alphabet, lol.

Do you know what the 'g' comes from in the industry? Has it been around for a while, or is it relatively new? And is it a [insert country] thing, or do you know if the ass-backwards americans use it as well?

That's seriously one of the worst letters they could possibly pick. Better I learn about it here, though. LOL
