A well completion system and associated methods of completing wells provides enhanced convenience in well completions involving well treatment operations. In a described embodiment, a single trip perforating and fracturing/gravel packing method permits a well completion assembly including a well screen and a perforating gun to be installed in a well, the well to be perforated and treated, and the perforating gun to be retrieved from the well in a single trip. Retrieval of the perforating gun permits multiple zone completions in the well without the perforating guns remaining in the well thereafter.
