Patent ID: 7631696

Claim:
A zone isolation assembly array for a subsurface well, the subsurface well including a surface region, a first zone, a second zone and a third zone, each zone being positioned at a different depth from one another below the surface region, the zone isolation assembly array comprising: a first docking receiver that is fixed within the subsurface well; a second docking receiver that is fixed within the subsurface well, the second docking receiver being positioned more proximate the surface region than the first docking receiver; a first docking apparatus that is adapted to be moved from the surface region to an engaged position with the first docking receiver to inhibit fluid communication between the first zone and the second zone; and a second docking apparatus that is coupled to the first docking apparatus, the second docking apparatus being adapted to be moved from the surface region to an engaged position with the second docking receiver to inhibit fluid communication between the second zone and the third zone, the second docking apparatus moving away from the engaged position at a different time than the first docking apparatus moves away from the engaged position.
