Casing Attachments

Casing attachments are items   attached to the casing outer diameter (OD) as the casing is run in the   wellbore. These items are designed to contribute to a successful primary   cementing job, helping to enable complete cement coverage and achieving the   designated top of cement. Over time, numerous casing attachments have been   developed for use in primary cementing operations. These attachments can help   the operator successfully place the casing string in the well and enhance mud   removal from the wellbore. The type of casing attachments used depends on   individual well requirements. 

Secondary (remedial) cementing   has become very expensive. Casing attachments can provide an inexpensive   alternative by helping optimize primary cementing success. Proper placement of   the primary cementing slurry is as important as the correct slurry design.   The effective use of casing attachments can help optimize slurry placement   by:

Assisting with running and   landing tubulars to the targeted depth for effective wellbore architecture;

Helping achieve optimum   circulation for mud displacement and slurry placement for successful zonal   isolation;

Helping reduce the chances of   differential sticking of the tubulars.

PYZS offers a wide array of casing attachment products for successful cement placement slurries. These include devices such as centralizers, stop collars, cement baskets, and scratchers and wipers that condition the wellbore and optimize casing positioning.
