A completion assembly has a packer for isolation and indicating shoulders incorporated into a sleeve mounted uphole of the packer. Locating the indicating shoulders above the packer allows them to be larger than placement below the packer where the assembly generally has to neck down to permit operations such as gravel packing. Placement above the packer makes the indicating shoulders less restrictive to subsequent production flow or for passage of tools further down the wellbore.
