On an open loop system it is possible to take water from one well, run

Yes, but...

The engineering is the sticker. How fast are you going to pull water
out and how fasst will it perculate back? You could easily pull more
out than will perculate back in.

You don't say what your goal is. Water loop for a heat exchanger?

The flow rate should be about 6 gpm through a water-to-water heat
exchanger.
