some very interesting jobs in here.
I am a "seinor field professional" I run a wireline crew in the oilfields of wyoming for one of the largest oilfield service company's in the world.
I have a large truck with my office and a spool of steel cable on the back, a 26 ton truck crane, and an F-350 with a 14k gross trailer.
the cable has a copper conducter down the center. to that cable i can hook tools that will tell me where the oil is, what the shear strength of the rock is, porosity, elemental make up, cement quality, and I use explosives to punch holes and do other things in the well bore.
one of the tools I am our local expert on has what amounts to a miniture partical accelerator in it to blast the formation with neutron rad. equivlent to about a 50 Ci chemical source, but at much higher energy levels. we then detect the resulting gamma rays, their energy levels and the decay time of the captured neutrons to tell us all sorts of interesting info about the rock and the fluid behind the steel casing.
i am licensed by the NRC, BATFE, and have a CDL for hazmat transport.
ah, what the heck:
