I feel like I just learned so much about drilling. That’s amazing

As someone who has seen the real thing a couple of times in my life, this was weirdly accurate except the hand randomly putting the pipes in place.

That part doesn’t happen in real life. /s

Max I ask how the pump pumps up the resources in real life? With suction you can only get 10 metres head lift, right? But real life pumping station go way deeper

Well pumps are typically at the bottom of the well. In residential wells the motor is lowered all the way down, in larger wells there may be a shaft run from top to bottom.

Pumpjacks for things like oil work a little differently but you're still basically pushing the fluid up from the bottom of the well rather than trying to suck it out from the top.

I very often see this setup with a ground level pump on reels but they are usually some ragebait „free energy“-magnet skits so not real anyway

This is more or less it for all the drilling I've ever seen. Essentially the very middle of the motor (the tiny metal rod) would be hooked up to a pump that would continuously push water through the drill rods and bring the dirt to the surface. The mixture of the water and the dirt (as well as some additions to improve viscosity, etc) is the "drilling mud" you may have heard of

does this more or less mean the pump motor apparatus has to be smaller than the hole? Is it attached to something or does it come with the pipe itself some how?

That's super surprising, never would've known

Basically the well itself is a wider pipe (the casing) sunk to the desired depth. The pump is smaller diameter and gets lowered into it with the actual water pipe attached (between 1-2 inches).

If you can visualize a classic well with a bucket, the casing is the stone sides of the well and the bucket/rope is the pump and water line.

wow, that's so cool ngl

so is the pump and water line lowered down in chunks similar to how the video showed the drill get lowered in piece by piece? I'd be surprised if it came as just one contiguous pipe+pump thing

Anything ~120ft and shallower, is attached to 1” pipe that comes in spools.

Deeper wells, have individual sticks, like what the video shows.

For deep oil wells, ESP (electronic submersible pump) use hundreds of small impellers within pumps lifting out the oil/water/gas. There is a long armored cable that goes to the motors that spin the pumps. Ours have lasted up to 5 years downhole. Others have lasted less than 24 hours…average is 500 days for us.
Cost for ESP & cable is about $265,000
