Abstract
A zone isolation assembly for a fluid monitoring system in an existing subsurface well includes a fluid receiving pipe, a docking receiver, a docking apparatus and a first sealer. The fluid receiving pipe includes a pipe interior and a fluid inlet structure. The fluid receiving pipe receives a fluid through the fluid inlet structure into the pipe interior. The docking receiver is connected to the fluid receiving pipe. The docking apparatus moves between (i) a docked position wherein the docking apparatus is docked with the docking receiver, and (ii) an undocked position wherein the docking apparatus is undocked with the docking receiver. The first sealer is spaced apart from the docking apparatus. In certain embodiments, the first sealer selectively forms a fluid-tight seal between the fluid receiving pipe and the casing to divide the fluid zone into a first zone and a spaced apart second zone. The first zone and the second zone are not in fluid communication with one another when the docking apparatus is in the docked position.
