Abstract
A deep well system for obtaining artesian samples is set forth. There is a first sample recovery pump which is operated to recover a sample and deliver it to the surface and through a sample flow line. It is surrounded by a packer which is inflated to isolate the region below the sample pump. The sample pump inlet is on the bottom side.
