The 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.

The port collar has a full opening to allow other tools to pass without restriction.
The Port Collar Shifting Tool uses spring loaded blocks that locate in the cementing sleeve providing a tie to the workstring. Download PDF
