A zone isolation apparatus is provided which allows for selective communication of fluid between a workstring and one or more subterranean zones. Fluid-pressure actuated packers may be placed in any desired location within a workstring without regard to the placement of the other packers, allowing maximum user flexibility and on-site configuration of the zone isolation apparatus. Each packer includes a rotary coupling to allow rotation of the workstring during running and sealing modes of operation. A latch mechanism is provided to prevent premature or accidental inflation.
