Seal Bore Extension runs below a drillable or retrievable seal bore packers. Seal Bore Extension is run to provide additional sealing bore when a long Seal Bore Assembly is run to accommodate considerable tubing movement. The Seal Bore Extension has the same ID as the corresponding Packer seal bore it is run with. Thus all seals of a long Seal Assembly seat off in the Seal Bore Extension. If the top set of seal normally sealing in the Packer bore should get damaged, the Seal Bore Extension still provide a sealing surface for the lower seat.
