I don't know about the really deep wells, but the average 2300 foot
depth wells around here use sucker rods that are the same size
all the way down. You can get an idea of how heavy it all is by looking
at the weights which counterbalance it on the other end of the walking
beam. It is all nicely counterbalanced so the pump motor doesn't have
to lift the weight of the rod on each stroke. BTW the rods screw together
from 20 or 30 foot sections, they aren't all one piece. That would make
it awfully hard to get them in or out of the well.

I figured as much. I find this drilling stuff interesting. I forget
who but someone was recalling some story about droping a wrench
"downhole". I never thought of that before. These deep holes it'd
probably take five minutes for it to hit bottom. I can't imagine what
it'd take to get it back out, big magnet and a long string....
