The ACT Polished Seal Bore Receptacle is designed for applications where a large ID must be maintained through the completion while accommodating extreme tubing movements. The ACT 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.
