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.

Halliburton 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.

Summary Summary Formation Packer Shoes-H07160
Halliburton formation packer shoes are installed on the bottom of casing in applications where casing will be set on top of a producing formation. In addition to the standard packer shoe line offered by Halliburton, premium threads are available for specific customer applications. Typically, formation packer shoes are used to pack off an open hole below the casing to help protect low pressure formations against cement contamination.
Summary Summary E&P: Using buoyancy-assisted casing equipment to extend lateral reach
A major challenge in lengthy horizontal or highly deviated wellbores is running the casing string to depth. Drag between the casing string and the formation can often exceed the load capacity of the casing hook, preventing tools from reaching optimal setting depth.
