[QUOTE="Redgully, post: 1630430, member: 33533"] So with mud drilling they take samples of the cuttings coming up every meter and wash it and that tells you what you're drilling through so if you see iron stained sand you have a pretty good idea there is water. If you get smooth 'washed' pebbles you know you hit really good water. Quartz is a good sign too. When you hit rock or granite you stop mud drilling and put in casing. They then go down with air and slowly clean the hole until only water is coming up and you can start to see what sort of water flows you have. Then you can put a hammer drill bit on and start drilling the rock looking for more water. When you air drill using just foam it is like in the movies, you get a massive gush of water if you hit a good strike, usually in granite, you hit a crack in the rock and get drenched. That is always exciting to watch. You see the rod drilling hammering away and it is loud and slow, everyone is standing watching and talking, then the hammer stops, the rod drops a foot or two and starts hammering again, you know you got a crack. Everyone stops talking and is watching the hole, could be a dry crack or lots of water. The rig operator is nervous because he may be just about to be drenched.....and woosh up it comes and you can't wipe the smiles of peoples faces. Best part of drilling. [/QUOTE]
