Seal Bore Extension is used in completions where a seal bore packer is used as a production packer and tubing movement is expected. Seal Bore Extension provides sufficient seal bore length so that long seal assemblies accommodate tubing movement while always remaining in the seal bore. Multiple seal bore extensions can be coupled together using a concentric coupling to obtain more seal bore length. Seal Bore Extensions are available for all sizes of seal bore packers. Seal Bore extensions are manufactured from materials that comply with NACE MR0175 STD. For SSC-resistant metallic material.
The PARVEEN Polished Seal Bore Receptacle is designed for applications where a large ID must be maintained through the completion while accommodating extreme tubing movements. The PARVEEN Polished Seal Bore Receptacle modular design allows tool to be easily converted from tension release to hydraulic release. The tension release and the hydraulic release incorporate a Polished Seal Bore Receptacle as well as a PBR seal assembly including 2 sets of working seal units and a debris barrier above and below the working seals. Both versions when combined with a hydraulic or hydraulic/ hydrostatic set can be run in and set in one trip.The polished seal bore receptacle can be retrieved in two trips.The seal assembly is retrieved when the tubing string is recovered. The PBR seal bore is retrieved with a PBR retrieving tool. The Polished Seal Bore Receptacle is available in varying lengths of up to 25 ft. in stroke. An adjustable shear mechanism locks the outer housing and seal mandrel together during run-in. Once the seal assembly is released, it is free to move in the bore, compensating for tubing movement. The PBR assembly can be pinned in the fully stroked, closed or midway position to accommodate pre-spacing in one-trip completions.
