Abstract

A zone isolation assembly array (794) for a well (712) includes a first zone isolation assembly (722A) and a second zone isolation assembly (722B). The first zone isolation assembly (722A) selectively inhibits fluid communication between a first zone (726) and a second zone (728) of the well (712). The second zone isolation assembly (722B) selectively inhibits fluid communication between the second zone (728) and a third zone (796) of the well (712). In another embodiment, the zone isolation assembly array (794) includes a first docking receiver (748A), a second docking receiver (748B), a first docking apparatus (750A) and a second docking apparatus (750B). The docking receivers (748A, 748B) can be positioned in an in-line manner. The second docking apparatus (750B) is coupled to the first docking apparatus (750A).
