Abstract
A zone isolation assembly () for a subsurface well () having a surface region (), a first zone () and a second zone () includes a docking receiver () and a docking apparatus (). The docking apparatus () is selectively moved relative to the docking receiver () between a disengaged position and an engaged position. In the disengaged position, the first zone () is in fluid communication with the second zone (). In the engaged position, the first zone () is not in fluid communication with the second zone () during movement of a fluid between the first zone () and the surface region (). The docking apparatus () can be maintained in the engaged position substantially by a force of gravity. The zone isolation assembly () can include a pump assembly () that pumps the fluid while the docking apparatus () is in the engaged position. The zone isolation assembly () can include a fluid collector () that collects the fluid when the docking apparatus () is in the engaged position.
