Cement Cleanout Blocks

Clears cement from casing

Cement cleanout blocks can be run in tandem with a standard Rhino XS hydraulically expandable reamer, enabling removal of the cement sheath that forms in the casing ID when drilling out the shoe track. Flow through the reamer activates the cutter blocks.

Cement cleanout blocks increase stability when drilling new formation after the shoe track has been drilled out. In addition, they reduce the risk of stuck BHAs by providing dependable cutter block retraction.

Schlumberger offers cement cleanout blocks in several sizes and configurations to accommodate a wide range of casing IDs.
