Small well drilling rig, how to drill a water well

This is one of our first experiences drilling with the well rig I made. We learned a lot about what improvements we would make in the hydraulic controls. We hit natural clay most of the way and this is a major problem, because you have to change out your drilling mud frequently as it gets very thick and gooey. It would have been better to have some polymer in our bentonite but it's hard to acquire in Mexico. (I adjusted the volume on this video but you may have to tweak it yourself - the motors can be very loud.)

It's a good question. You are correct in assuming that much of the veins of water are clogged during the drilling process by the "mud" but after you've drilled to the depth you want and put the casing in with the gravel pack, you start the development process. This process is very time consuming in removing the mud from the walls but you can now do it because the walls of the well are stabilized by the casing and gravel. I hope that helps.

Nice work.does this work in rock efficiently. Or only for soil..

[@2edge4him]

We have made are way through some rock but it's very hard on bits and it's very time consuming. Thanks for your interest.

U have used hydraulic motor for rotation instead of electric motor. What's the benefit of it. Thanks. I will wait for your answer.

[@2edge4him]

Mostly the power of hydraulics is superior and electricity wasn't always near by.

Very impressive David! How long did it take you to build your rig?

[@2edge4him]

I didn't see this post and am now just giving a reply. It took about a year with all the changes and not working on it full time.

what do you mean by polymer? also have you drill in sand?

[@2edge4him]

Polymer comes in powder form that thickens the water in the drilling process. Thicker water, or drilling mud, then helps pull up the cuttings made from the drill bit in the bore hole. With thicker mud you can bring to the surface larger and heavier cuttings like gravel. Drilling in sand doesn't take thicker mud because it is not as heavy as gravel BUT you may need thicker mud to coat the walls of the borehole to keep the formation solid in the well so it doesn't collapse. It's a difficult thing to know how thick your mud should be as it effects many things in the process of drill and is critical in having a successful well. Sand is very difficult to drill in as it wants to collapse on top of the drill bit. You have to take special precautions to not get your bit stuck and it mostly deals with covering the walls with a thick layer of polymer and other things. I hope that helps.

I am looking for a machine like this one, How can I get one?

[@2edge4him]

I fabricated this drilling rig from scratch, its my own design. Thanks for your interest.

Hi jeff

[@ojbarberena7090]

I have a question about the mud- polymer that is used while drilling, as you mention it covers the walls and prevents collapsing the walls, at the same time wont this mud clog the veins of water that feed the well? Thank you
