Abstract
A method and well tool for using a low-viscosity slurry to gravel pack a completion interval. The well tool is comprised of a screen and at least one alternate flowpath which is initially closed to flow by a valve means. Once a sand bridge is formed in the completion interval, the pressure of the pumped slurry increases which, in turn, opens the valve means to allow flow through the alternate flowpath. Preferably, a plurality of flowpaths of different lengths are provided, all of which include valve means which are adapted to open at different pressures.
