Apparatus for and method of gravel packing a well, wherein a well liner is run into a well bore on a hydraulically set packer assembly which is releasably supported on a setting tool which provides a fluid flow crossover and seals which are selectively positionable within the packer body and a sealing receptacle in the liner. A ball is dropped to enable pressure to set the packer. The running tool is released and moved upwardly to a circulating position at which fluid can circulate downwardly through the running pipe string and the running tool, through the crossover to the annulus outside the liner to deposit gravel, the fluid flowing upwardly through the crossover and past the packer into the annulus outside of the running pipe string. The running tool is then moved further upwardly to position the seals for reverse circulation of fluid down the annulus outside of the running pipe string and through the crossover into the liner, and then back through the crossover into the running in pipe string. All of the setting, circulating, gravel placement and reverse circulating operations are performed during a single trip of the equipment into the well bore.
