Abstract: Well assemblies and related systems and methods are disclosed. In accordance with an implementation, an apparatus includes a body having a first wall, a second wall, a cover, and an impermeable barrier. The first wall defines a well having a port and a distal end defining an opening having an opening perimeter. The second wall surrounds the first wall and has a distal end. The cover is coupled to the distal end of the first wall and covers the opening along the opening perimeter at a connected portion and uncoupled from the distal end of the first wall along the opening perimeter at an unconnected portion. The impermeable barrier is coupled to the distal end of the second wall and covers the well. The unconnected portion forms a vent that allows air flow out of the well.
