USAID, UNICEF, RWSN and NGO's "FAIL" in large diameter irrigation, exploration, and mining, hand borehole drilling !!!!

Neither USAID, UNICEF, RWSN nor any NGO, mining company or other driller, other than wellinventions.com or onemillionwells.org can drill a hand drilled borehole large enough to remove this massive boulder from the bottom of their borehole.

Wellinventions and onemillionwells use a 8inch diameter drill stem to drill and remove large gravel from boreholes - gravel no other organization can remove. And this is not the largest theoretical size boulder that can be removed. Stones this size can be removed either with hand drilling tools or with a powered drill. One would say, it is impossible to remove such large stones from a hand drilled borehole. But the reverse flow method developed by wellinventions.com can remove any size stone that will fit within an available drill stem. And the drill stems are available in any size that is standard in the PVC pipe line of any manufacturer. Many manufacturers extrude pipe from 2 inches up to 24 inches in diameter.

HOW CAN THIS BE TRUE????? How can one drill by hand with an 8 inch or larger drill stem. One simply fabricates the drill stem with joints that are short enough and of thin enough wall that they can be handled by hand. We use 8" pipe, (5 pounds per foot) that is 5 ft. long and it is easily lifted by a single man. It is simple to remove a large stone, one simply fabricates a drill stem using the formula found in U.S. Patent 9,915,113 and matches it with the appropriate compressor and the stone is sucked up the drill stem to the surface and deposited in the mud pit. Using the formula guarantees that the slip velocity required will lift the stone, move it up the drill stem and shoot it under power into the mud pit. Well, one might ask, how is the drill stem removed by hand after the large stone is removed and the borehole reaches designed depth? Using the methods outlined in the patent, the drill stem has its outlet ports plugged and then air is introduced into the drill stem. When the air enters, it displaces the drill fluid making the drill stem into a floating plastic pipe. The pipe is simply allowed to rise under its buoyancy until a joint is reached, then the pipe is supported on a "fork" until the first section is removed. After the first joint is removed, the process is continued until the entire drill stem is removed from the borehole.

What does this mean for you, whether you are a farmer needing a well or a miner needing a method to mine placer meterials at your mine site. It means that you can operate in areas that were never before capable of being drilled. If you are a farmer and need the most water possible from your farmland, this drill will drill in gravel, when the most water lies. If you are a miner, then this drill will allow you to bring up gemstones or ore that could never before be removed by any other hand operated drill.

And if you are simply a person that wants water, this drill will drill deeper, cheaper and more efficiently than any other drill ever manufactured.

There is no reason for any government organization, NGO or mining company to ever use any other method of drilling other than the method of drilling patented by Wellinventions.com.
