Abstract:

A universal washdown system for circulating fluid through a wellbore to clean debris therefrom and to gravel-pack a production zone is provided. The system includes a production assembly with a multi-position service tool assembly disposed therein. The multi-position service tool is connected to and sealingly engages a packer that is included in the production assembly. The multi-position service tool assembly moves from a first to a second position in the production assembly by pulling longitudinally thereon. The apparatus is lowered into the well with the service tool connected to the production assembly in the first position. When the service tool assembly is in the second position, fluid passing down through a longitudinal central flow passage defined therethrough is communicated with an annulus defined between a liner assembly and the wellbore through crossover ports defined in the service tool to allow a gravel pack fluid to pass into a desired formation.
