Abstract
A multi-zone packing system having unique features that allow for remote operation, thereby eliminating the need to raise and lower a work string and crossover tool to various zones of interest during a frac pack, gravel pack or related completion procedure. The squeeze pack system has a crossover tool or port collocated with each zone of interest and remotely operated closing devices to allow for the setting of each packer and the packing job to be performed with minimal or no movement of the work string.
