Abstract
A new gravel packing system is provided whereby a well may be perforated, gravel packed and placed on production with a single trip of the tool string into the well. The system will include a crossover assembly which has a closure mechanism operatively associated therewith. The closure mechanism may be operated to preclude downward fluid flow through the crossover tool, to establish at least a portion of a downward gravel pack slurry flow path, and to establish at least a part of a carrier fluid return flow path. At the conclusion of a gravel pack operation, the closure member may be either withdrawn from the assembly or expelled to the bottom of the wellbore, leaving the tool to be placed on production without tripping the tool string.
