Abstract
A gravel packing system for re-entry of a screen assembly by a completion tool having an inflate packer as an isolation barrier for minimizing the necessary height of the gravel pack within the casing and thus maximizing the production interval of a well to permit a higher rate of production. The invention assures re-entry of tools to a gravel pack screen assembly for well completion following a gravel pack operation. A guiding and anchoring tool is run through a casing restriction and/or well tubing to a desired position below the restriction and/or tubing and within the casing and is actuated for anchoring. Guide fingers are formed downhole into a tool guiding configuration and the tool is left anchored within the well casing. Subsequently, a well completion tool is and guided into and latched within the guiding and anchoring tool and the inflate packer is set to enable optimum well production.
