Multi-stage cementing tools allow the cementing of selected intervals of the casing string to be executed in different stages. Stage collars are a frequent requirement in cementing operations when two or more separate sections behind the same casing string need cementing or for selectively cementing above inflatable packers. Saga group offers mechanical and hydraulic designs of stage collars that are available in a wide range of incremental sizes and manufactured to match up to customers casing grade, weight and thread type. For more information about Saga stage collars, contact [email protected].
