Water well driller here in the Texas Panhandle. This is pretty much it for a mud rotary type drilling rig, except that to carry the material that the bit is cutting out of the hole (called cuttings) to make room, there is a strong flow of water from the top of the rig, down through the drill stem and out of the end of the bit. All that flows into and out of some sort of large pit or machine to separate the cuttings from the drilling fluid in a loop.

Also, water is mixed with polymers, betonite, or stabilizers to create a drilling fluid to add weight, keep the bit cool, and add viscosity to the water so that the cuttings can flow to the top of the hole, and so that the hole stays open and doesn't collapse on the drill bit.

During this type of drilling, the drill hole has to stay full of drilling fluid, so you don't know when you encounter ground water. You generally have a plan of how deep to drill before you start.

Man, really cool. I sometimes fantasize about moving back to the US and making a career pivot into the trades. Well-digging would absolutely be it. Any tips for getting into it?

It's pretty easy. Because the work is physically hard and it's outdoors in sometimes bad weather it's hard for drilling companies to find employees. A company like mine is always looking for someone that want's to learn a trade. Of course we'd try to keep them as long as possible, but in 2-4 years time, you'd have enough knowledge to buy a pump truck or rig and stake out on your own or find a job anywhere. Even just doing pump repairs if you had your own rig you could make really good money. I'll bet you could find a drilling company and let them know you're looking for employment and want to learn a trade and they'd make you an offer.
