Abstract
A test system and method for testing a well having a first and second zone includes a chamber and an isolation device moveable in the chamber. The isolation device separates a first and a second portion of the chamber. The chamber is adapted to receive fluid in the second chamber portion from the first zone. The isolation device is adapted to be moved in the chamber in a first direction by the first zone fluid. The first chamber portion can be charged with fluid pressure to move the isolation device in a second direction to pump the first zone fluid inside the second chamber portion into the second zone.
