The ILS Cement Port Collar provides a full opening stage cementer that needs no plugs or balls to operate. An internal cementing sleeve is opened and closed with pipe manipulation using a shifting tool. Since no plugs are needed, multiple port collars can be run in a casing string. All can be operated with a single workstring trip. The port collar has a full opening to allow other tools to pass without restriction. The ILS Port Collar Shifting Tool uses spring loaded blocks that locate in the cementing sleeve providing a tie to the workstring. Once the blocks locate in the sleeve, right-hand pipe rotation and manipulation are used to open and close the sleeve. Multiple openings and closings are possible with each port collar.
