Abstract

A technique facilitates simplified cementing operations in a borehole with fewer trips downhole. The technique utilizes a cementing system having a stage cementing collar in combination with a cup tool. According to an embodiment, the stage cementing collar may comprise a collar body, a no-go connected to the collar body, and a port closure sleeve which serves as a valve positioned to close/open flow ports extending laterally through the collar body. The cup tool may be conveyed downhole on, for example, jointed pipe or coiled tubing, for engagement with the port closure sleeve. The cup tool is used to shift the port closure sleeve between operational positions, e.g. from a port open to a port closed position.
