A downhole system includes a first tubular having a first end, a second end, and an intermediate portion having an inner surface defining an interior. The second end includes one of a screen liner and a casing shoe. A second tubular is coupled to the first end of the first tubular. The second tubular includes a terminal end portion, a second end portion and a ported zone arranged between the terminal end portion and the second end portion. The terminal end portion and the ported zone extend into the interior of the first tubular. A packer member is arranged on the second tubular between the terminal end portion and the ported zone. The packer member is selectively expandable to seal against the inner surface to fluidically isolate the one of the screen liner and casing shoe from the ported zone.

Shoe isolation system and method for isolating a shoe

An isolation method is described for gravel packed zones separated by at least one packer and having an auxiliary conduit passing through the packer into adjacent zones. The conduit includes at least one each of a shunt tube, flow housing, annular space, and isolation valve housing. The flow housing, the annular space, and the isolation valve housing are all annular and formed between two concentric pipes. The method includes running in an assembly of screens isolated by at least one packer with at least one auxiliary conduit extending into adjacent zones defined by the packer when the packer is subsequently set. The method also includes closing flow in said conduit to prevent flow into shunt tubes during production based on creating a flow barrier in the annular space, the flow housing, or the isolation valve housing, the shunt tubes supplying slurry through the auxiliary conduit prior to the production.

Isolation packer with automatically closing alternate path passages

A gravel pack system includes a tool string having an inner string member, an outer string member, and a passage arranged between the outer string member and the inner string member. A packing element is provided on the outer string member. A first valve is coupled to one of the outer string member and the inner string member outwardly of the packing element in a downhole direction. The first valve fluidically connects the passage and the open hole wellbore. The first valve is configured and disposed to shift from a closed position to an open position. A second valve is coupled to one of the outer string member and the inner string member outwardly of the packing element in an uphole direction. The second valve selectively fluidically connects the passage and the open hole wellbore. The second valve shifts from an open position to a closed position.
