A completion assembly for a wellbore, comprising a first tubular string extending at least part way into a wellbore and supporting at least a portion of a pump; at least one additional tubular string extending further into the wellbore and supporting an isolation device that divides the wellbore into an upper zone where said first string is disposed without contact of said isolation device and a lower zone exposed to a formation and where said first string does not extend, the at least one additional string comprising a valve which selectively allows flow through said isolation device to reach a lower end of said first string; the at least one additional string selectively separable adjacent said isolation device into upper and lower segments along its length in said upper zone with said valve remaining on said lower segment to allow said first string with said at least a portion of a pump and said upper segment to be removed from the wellbore while said lower zone is isolated with said valve.
