ABSTRACT:
A crossover tool assembly is run in with a packer and after the packer is set it is released from the packer for independent movement. The assembly is picked up to allow spring loaded dogs to come out so that upon setting down weight the crossover assembly has an outer assembly that is supported on the packer mandrel. The crossover mandrel can then be set down and picked up to operate a j-slot mechanism in the crossover. Relative movement induced by the j-slot with the outer assembly of the crossover supported by the dogs allows a return path within the crossover to be opened or closed independent of any contact with the packer mandrel.
