Hi Frank. Good to see you are still going at it.
On the well subject, I may be way off, but, instead of pushing that sand back out into the surrounding gravel, maybe a sand bucket down the well would allow the sand to be lifted out of the well and clear itself from the gravel ? 100 years ago, we would drive a screened point down into the stream and sometimes, after several years, we would shoot a .22 bullet down into the pipe and the concussion would help clear the screen, if it also didn't blow the screen out in the process. ::)
It's amasing how much sand can be taken out of a well in a days time, all by setting up a tripod and a pulley system. This was common for anything over 22' shallow wells before the rotary rigs were invented.
Frank S:
I can't say that I haven't thought of a bailing bucket, the thought of hauling one in and out of the well tens of hundreds of times is not a task that I relish even using a powered capstan. Even with that though the only real amount of sand that would be brought up would be that which is in the bore hole itself with a minor amount being drawn into the bore from the gravel. This is why aI am planning on constructing a kind of jet nozzle and use the power of high speed flowing water to suck the sand up out of the well.
Harold in CR:
AHhhh, must have read your post wrong. I thought it said blast the sand back through the gravel. :-[ :)
Frank S:
Sorry Harold I sometimes don't make my self perfectly clear Water or air either way, the high volume properly directed will suck the insides out of a bowling ball.
Back in my oilfield days we used to blast a 20" diameter hole 50 feet into the ground using nothing but an air driven rotary bit that had several nozzles, at a high volume and pressure. A deflector shield came loose once and there were rocks the size of soft balls going 100 feet into the air.
Harold in CR:
No problem, Frank. You are talking something similar to a rotary drill rig using water to flush the cuttings up and out. I get that.
