Zusammenfassung:	A system and method for deployment of an isolation seal assembly wherein an isolation seal assembly is releasably attached to a reverse circulation debris removal tool (130). The system includes a debris removal tool (130) having a head with an elongated snorkel extending from the head; and an isolation seal assembly attached to the head with a shear device so that the snorkel (134) protrudes past the end of the isolation seal assembly. The isolation seal assembly further includes a tubular (122) with a latch adjacent a first end (142), an external seal below the latch, and openings (120) formed along tubular (122) between latch and the seal. The debris removal tool (130) is used to engage the isolation seal assembly with a lower completion assembly (82). The openings (120) in the isolation seal assembly permit the debris removal tool (130) to continue to function after the isolation seal assembly is engaged with the lower completion assembly (82).
