Default new well casing depth

Just had a well drilled a couple weeks ago, its a 6" casing , I had an old drilled well at 80' that went dry was only getting 1 gpm recovery . new well is 141' . only problem is I looked at the bill and it says they drilled 141' after 8' they hit limestone until 141' they only put 23' of casing in and the rest is just a hole in rock, is this normal? I thought the casing is supposed to be quite a bit farther down then that,

Casing is only used until they hit rock. The main purpose of the casing is to prevent surface water from entering the well.

Where are you located?

Sounds like they went a long way into the lime rock that probably wasn't necessary. As porous as most limerock is, going that far to get a usable amount of water is overkill. It also makes it easy to have more hardness, iron, sulphur and other undesirables. I'll bet the rig was a Rotary.
