1. A bottom hole assembly (BHA) conveyed downhole on a conveyance string for actuating a selected sleeve assembly of one or more sleeve assemblies located along a completion string, comprising:
a shifting tool comprising a BHA mandrel slidable within a BHA housing downhole thereof, the BHA mandrel having a resettable packer thereon, the BHA housing having slips and one or more sleeve engagement elements at an uphole end thereof, wherein the packer is released when spaced from the slips and set when engaged therewith;
a drag block downhole of the shifting tool for impeding movement of the BHA housing relative to the completion string;
a telescopic BHA repositioning sub connected to the shifting tool, the repositioning sub having a slack mandrel telescopically-coupled to a slack housing, wherein the telescopic BHA repositioning sub is telescopically extendible and collapsible between:
an axially extended configuration in which the one or more sleeve engagement elements engage the selected sleeve assembly with the packer spaced from the slips; and
an axially collapsed configuration in which the one or more sleeve engagement elements are shifted downhole of the selected sleeve assembly, towards the drag block, with the packer spaced from the slips;
wherein, when the telescopic BHA repositioning sub is in the axially collapsed configuration, the BHA mandrel is movable with respect to the BHA housing to engage the packer with the slips to set the packer.
