ACT Overshot Expansion Joint (OEJ) Assembly is designed for applications where extreme tubing movements are expected due to stimulation or production of the well and when a tubing separation device is also required.
The OEJ assembly is a one-trip system, which allows the well to be flanged up prior to setting the packer. The OEJ assembly incorporates a slick joint sub as well as housing – packing set including working seal units and a debris barrier above the working seals. The plain receptacle, housing – packing set and seals can be retrieved when the tubing string is recovered for maintenance or the entire completion can be retrieved by straight pull after ensuring that J-pin engaged with J-slot, thus allowing the packer to be retrieved.
The OEJ assembly is available in varying lengths of up to 20 ft. stroke. Adjustable shear pins lock the inner & outer assembly together during run-in. Once the shear screw gets sheared by applying load, the outer assembly gets disengaged and it is free to move on the inner assembly, compensating for tubing movement.
