Not to hijack, but couldn't help myself........
Twisted..you a mud man? What company? I worked for Imco Services from 75-77, and Western Mud/Geo International from 77-92. Was the mud engineer on the deepest well in Ca (I THINK the record still holds......Elk Hills 26,000 +). Got out in 92 and never looked back. Shit load of money even back then, but got REAL tired of the "I'm the boss and you should kiss my ass" mentality of some of the company men, especially when they didn't know shit from shinola about MY mud!
OP, if you can drive a truck, adjust a 36" pipe wrench w/ one hand, or just willing to learn, you can do well. Worked 7 years as a Master Derrickman for Loffland Bros. Drilling Co. and still have all my fingers. Was dicey a few times tho. Broken arm, 28 stitches in the scalp (still have my Dad's old six band aluminum hard hat that saved my ass), a couple of different broken fingers, and a scar on my chin (that one knocked me out of the derrick of a 147 Lee C. Moore triple. Rope belt saved me. Unconscious and hanging there till they could air hoist me down). Twisted is right watch out for the worms. They'll get ya. Everyone of my episodes was the result of someone else's fuckup. Truly.
If you can get some engineering education in the field, you're life will be a lot simpler and more financially rewarded. Good luck on whatever you decide.
